CC0 1.0 Universal
Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator and
subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for the
purpose of contributing to a commons of creative, cultural and scientific
works ("Commons") that the public can reliably and without fear of later
claims of infringement build upon, modify, incorporate in other works, reuse
and redistribute as freely as possible in any form whatsoever and for any
purposes, including without limitation commercial purposes. These owners may
contribute to the Commons to promote the ideal of a free culture and the
further production of creative, cultural and scientific works, or to gain
reputation or greater distribution for their Work in part through the use and
efforts of others.
For these and/or other purposes and motivations, and without any expectation
of additional consideration or compensation, the person associating CC0 with a
Work (the "Affirmer"), to the extent that he or she is an owner of Copyright
and Related Rights in the Work, voluntarily elects to apply CC0 to the Work
and publicly distribute the Work under its terms, with knowledge of his or her
Copyright and Related Rights in the Work and the meaning and intended legal
effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not limited
to, the following:
i. the right to reproduce, adapt, distribute, perform, display, communicate,
and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or likeness
depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data in
a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation thereof,
including any amended or successor version of such directive); and
vii. other similar, equivalent or corresponding rights throughout the world
based on applicable law or treaty, and any national implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention of,
applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and
unconditionally waives, abandons, and surrenders all of Affirmer's Copyright
and Related Rights and associated claims and causes of action, whether now
known or unknown (including existing as well as future claims and causes of
action), in the Work (i) in all territories worldwide, (ii) for the maximum
duration provided by applicable law or treaty (including future time
extensions), (iii) in any current or future medium and for any number of
copies, and (iv) for any purpose whatsoever, including without limitation
commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes
the Waiver for the benefit of each member of the public at large and to the
detriment of Affirmer's heirs and successors, fully intending that such Waiver
shall not be subject to revocation, rescission, cancellation, termination, or
any other legal or equitable action to disrupt the quiet enjoyment of the Work
by the public as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason be
judged legally invalid or ineffective under applicable law, then the Waiver
shall be preserved to the maximum extent permitted taking into account
Affirmer's express Statement of Purpose. In addition, to the extent the Waiver
is so judged Affirmer hereby grants to each affected person a royalty-free,
non transferable, non sublicensable, non exclusive, irrevocable and
unconditional license to exercise Affirmer's Copyright and Related Rights in
the Work (i) in all territories worldwide, (ii) for the maximum duration
provided by applicable law or treaty (including future time extensions), (iii)
in any current or future medium and for any number of copies, and (iv) for any
purpose whatsoever, including without limitation commercial, advertising or
promotional purposes (the "License"). The License shall be deemed effective as
of the date CC0 was applied by Affirmer to the Work. Should any part of the
License for any reason be judged legally invalid or ineffective under
applicable law, such partial invalidity or ineffectiveness shall not
invalidate the remainder of the License, and in such case Affirmer hereby
affirms that he or she will not (i) exercise any of his or her remaining
Copyright and Related Rights in the Work or (ii) assert any associated claims
and causes of action with respect to the Work, in either case contrary to
Affirmer's express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or warranties
of any kind concerning the Work, express, implied, statutory or otherwise,
including without limitation warranties of title, merchantability, fitness
for a particular purpose, non infringement, or the absence of latent or
other defects, accuracy, or the present or absence of errors, whether or not
discoverable, all to the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without limitation
any person's Copyright and Related Rights in the Work. Further, Affirmer
disclaims responsibility for obtaining any necessary consents, permissions
or other rights required for any use of the Work.
d. Affirmer understands and acknowledges that Creative Commons is not a
party to this document and has no duty or obligation with respect to this
CC0 or use of the Work.

# bats-assert
[![License](https://img.shields.io/npm/l/bats-assert.svg)](https://github.com/jasonkarns/bats-assert-1/blob/master/LICENSE)
[![GitHub release](https://img.shields.io/github/release/jasonkarns/bats-assert-1.svg)](https://github.com/jasonkarns/bats-assert-1/releases)
[![npm release](https://img.shields.io/npm/v/bats-assert.svg)](https://www.npmjs.com/package/bats-assert)
[![Build Status](https://travis-ci.org/jasonkarns/bats-assert-1.svg?branch=master)](https://travis-ci.org/jasonkarns/bats-assert-1)
`bats-assert` is a helper library providing common assertions for
[Bats][bats].
Assertions are functions that perform a test and output relevant
information on failure to help debugging. They return 1 on failure and 0
otherwise. Output, [formatted][bats-support-output] for readability, is
sent to the standard error to make assertions usable outside of `@test`
blocks too.
Assertions testing exit code and output operate on the results of the
most recent invocation of `run`.
Dependencies:
- [`bats-support`][bats-support] (formerly `bats-core`) - output
formatting
See the [shared documentation][bats-docs] to learn how to install and
load this library.
## Usage
### `assert`
Fail if the given expression evaluates to false.
***Note:*** *The expression must be a simple command. [Compound
commands][bash-comp-cmd], such as `[[`, can be used only when executed
with `bash -c`.*
```bash
@test 'assert()' {
touch '/var/log/test.log'
assert [ -e '/var/log/test.log' ]
}
```
On failure, the failed expression is displayed.
```
-- assertion failed --
expression : [ -e /var/log/test.log ]
--
```
### `refute`
Fail if the given expression evaluates to true.
***Note:*** *The expression must be a simple command. [Compound
commands][bash-comp-cmd], such as `[[`, can be used only when executed
with `bash -c`.*
```bash
@test 'refute()' {
rm -f '/var/log/test.log'
refute [ -e '/var/log/test.log' ]
}
```
On failure, the successful expression is displayed.
```
-- assertion succeeded, but it was expected to fail --
expression : [ -e /var/log/test.log ]
--
```
### `assert_equal`
Fail if the two parameters, actual and expected value respectively, do
not equal.
```bash
@test 'assert_equal()' {
assert_equal 'have' 'want'
}
```
On failure, the expected and actual values are displayed.
```
-- values do not equal --
expected : want
actual : have
--
```
If either value is longer than one line both are displayed in
*multi-line* format.
### `assert_success`
Fail if `$status` is not 0.
```bash
@test 'assert_success() status only' {
run bash -c "echo 'Error!'; exit 1"
assert_success
}
```
On failure, `$status` and `$output` are displayed.
```
-- command failed --
status : 1
output : Error!
--
```
If `$output` is longer than one line, it is displayed in *multi-line*
format.
### `assert_failure`
Fail if `$status` is 0.
```bash
@test 'assert_failure() status only' {
run echo 'Success!'
assert_failure
}
```
On failure, `$output` is displayed.
```
-- command succeeded, but it was expected to fail --
output : Success!
--
```
If `$output` is longer than one line, it is displayed in *multi-line*
format.
#### Expected status
When one parameter is specified, fail if `$status` does not equal the
expected status specified by the parameter.
```bash
@test 'assert_failure() with expected status' {
run bash -c "echo 'Error!'; exit 1"
assert_failure 2
}
```
On failure, the expected and actual status, and `$output` are displayed.
```
-- command failed as expected, but status differs --
expected : 2
actual : 1
output : Error!
--
```
If `$output` is longer than one line, it is displayed in *multi-line*
format.
### `assert_output`
This function helps to verify that a command or function produces the
correct output by checking that the specified expected output matches
the actual output. Matching can be literal (default), partial or regular
expression. This function is the logical complement of `refute_output`.
#### Literal matching
By default, literal matching is performed. The assertion fails if
`$output` does not equal the expected output.
```bash
@test 'assert_output()' {
run echo 'have'
assert_output 'want'
}
```
On failure, the expected and actual output are displayed.
```
-- output differs --
expected : want
actual : have
--
```
If either value is longer than one line both are displayed in
*multi-line* format.
#### Existence
To assert that any (non-empty) output exists at all, simply omit the matching
argument.
```bash
@test 'assert_output()' {
run echo 'have'
assert_output
}
```
On failure, an error message is displayed.
```
-- no output --
expected non-empty output, but output was empty
--
```
#### Partial matching
Partial matching can be enabled with the `--partial` option (`-p` for
short). When used, the assertion fails if the expected *substring* is
not found in `$output`.
```bash
@test 'assert_output() partial matching' {
run echo 'ERROR: no such file or directory'
assert_output --partial 'SUCCESS'
}
```
On failure, the substring and the output are displayed.
```
-- output does not contain substring --
substring : SUCCESS
output : ERROR: no such file or directory
--
```
This option and regular expression matching (`--regexp` or `-e`) are
mutually exclusive. An error is displayed when used simultaneously.
#### Regular expression matching
Regular expression matching can be enabled with the `--regexp` option
(`-e` for short). When used, the assertion fails if the *extended
regular expression* does not match `$output`.
*Note: The anchors `^` and `$` bind to the beginning and the end of the
entire output (not individual lines), respectively.*
```bash
@test 'assert_output() regular expression matching' {
run echo 'Foobar 0.1.0'
assert_output --regexp '^Foobar v[0-9]+\.[0-9]+\.[0-9]$'
}
```
On failure, the regular expression and the output are displayed.
```
-- regular expression does not match output --
regexp : ^Foobar v[0-9]+\.[0-9]+\.[0-9]$
output : Foobar 0.1.0
--
```
An error is displayed if the specified extended regular expression is
invalid.
This option and partial matching (`--partial` or `-p`) are mutually
exclusive. An error is displayed when used simultaneously.
#### Standard Input, HereDocs and HereStrings
The expected output can be specified via standard input (also
heredoc/herestring) with the `-`/`--stdin` option.
```bash
@test 'assert_output() with pipe' {
run echo 'hello'
echo 'hello' | assert_output -
}
@test 'assert_output() with herestring' {
run echo 'hello'
assert_output - <<< hello
}
```
### `refute_output`
This function helps to verify that a command or function produces the
correct output by checking that the specified unexpected output does not
match the actual output. Matching can be literal (default), partial or
regular expression. This function is the logical complement of
`assert_output`.
#### Literal matching
By default, literal matching is performed. The assertion fails if
`$output` equals the unexpected output.
```bash
@test 'refute_output()' {
run echo 'want'
refute_output 'want'
}
```
On failure, the output is displayed.
```
-- output equals, but it was expected to differ --
output : want
--
```
If output is longer than one line it is displayed in *multi-line*
format.
#### Existence
To assert that there is no output at all, simply omit the matching argument.
```bash
@test 'refute_output()' {
run foo --silent
refute_output
}
```
On failure, an error message is displayed.
```
-- unexpected output --
expected no output, but output was non-empty
--
```
#### Partial matching
Partial matching can be enabled with the `--partial` option (`-p` for
short). When used, the assertion fails if the unexpected *substring* is
found in `$output`.
```bash
@test 'refute_output() partial matching' {
run echo 'ERROR: no such file or directory'
refute_output --partial 'ERROR'
}
```
On failure, the substring and the output are displayed.
```
-- output should not contain substring --
substring : ERROR
output : ERROR: no such file or directory
--
```
This option and regular expression matching (`--regexp` or `-e`) are
mutually exclusive. An error is displayed when used simultaneously.
#### Regular expression matching
Regular expression matching can be enabled with the `--regexp` option
(`-e` for short). When used, the assertion fails if the *extended
regular expression* matches `$output`.
*Note: The anchors `^` and `$` bind to the beginning and the end of the
entire output (not individual lines), respectively.*
```bash
@test 'refute_output() regular expression matching' {
run echo 'Foobar v0.1.0'
refute_output --regexp '^Foobar v[0-9]+\.[0-9]+\.[0-9]$'
}
```
On failure, the regular expression and the output are displayed.
```
-- regular expression should not match output --
regexp : ^Foobar v[0-9]+\.[0-9]+\.[0-9]$
output : Foobar v0.1.0
--
```
An error is displayed if the specified extended regular expression is
invalid.
This option and partial matching (`--partial` or `-p`) are mutually
exclusive. An error is displayed when used simultaneously.
#### Standard Input, HereDocs and HereStrings
The unexpected output can be specified via standard input (also
heredoc/herestring) with the `-`/`--stdin` option.
```bash
@test 'refute_output() with pipe' {
run echo 'hello'
echo 'world' | refute_output -
}
@test 'refute_output() with herestring' {
run echo 'hello'
refute_output - <<< world
}
```
### `assert_line`
Similarly to `assert_output`, this function helps to verify that a
command or function produces the correct output. It checks that the
expected line appears in the output (default) or in a specific line of
it. Matching can be literal (default), partial or regular expression.
This function is the logical complement of `refute_line`.
***Warning:*** *Due to a [bug in Bats][bats-93], empty lines are
discarded from `${lines[@]}`, causing line indices to change and
preventing testing for empty lines.*
[bats-93]: https://github.com/sstephenson/bats/pull/93
#### Looking for a line in the output
By default, the entire output is searched for the expected line. The
assertion fails if the expected line is not found in `${lines[@]}`.
```bash
@test 'assert_line() looking for line' {
run echo $'have-0\nhave-1\nhave-2'
assert_line 'want'
}
```
On failure, the expected line and the output are displayed.
***Warning:*** *The output displayed does not contain empty lines. See
the Warning above for more.*
```
-- output does not contain line --
line : want
output (3 lines):
have-0
have-1
have-2
--
```
If output is not longer than one line, it is displayed in *two-column*
format.
#### Matching a specific line
When the `--index <idx>` option is used (`-n <idx>` for short) , the
expected line is matched only against the line identified by the given
index. The assertion fails if the expected line does not equal
`${lines[<idx>]}`.
```bash
@test 'assert_line() specific line' {
run echo $'have-0\nhave-1\nhave-2'
assert_line --index 1 'want-1'
}
```
On failure, the index and the compared lines are displayed.
```
-- line differs --
index : 1
expected : want-1
actual : have-1
--
```
#### Partial matching
Partial matching can be enabled with the `--partial` option (`-p` for
short). When used, a match fails if the expected *substring* is not
found in the matched line.
```bash
@test 'assert_line() partial matching' {
run echo $'have 1\nhave 2\nhave 3'
assert_line --partial 'want'
}
```
On failure, the same details are displayed as for literal matching,
except that the substring replaces the expected line.
```
-- no output line contains substring --
substring : want
output (3 lines):
have 1
have 2
have 3
--
```
This option and regular expression matching (`--regexp` or `-e`) are
mutually exclusive. An error is displayed when used simultaneously.
#### Regular expression matching
Regular expression matching can be enabled with the `--regexp` option
(`-e` for short). When used, a match fails if the *extended regular
expression* does not match the line being tested.
*Note: As expected, the anchors `^` and `$` bind to the beginning and
the end of the matched line, respectively.*
```bash
@test 'assert_line() regular expression matching' {
run echo $'have-0\nhave-1\nhave-2'
assert_line --index 1 --regexp '^want-[0-9]$'
}
```
On failure, the same details are displayed as for literal matching,
except that the regular expression replaces the expected line.
```
-- regular expression does not match line --
index : 1
regexp : ^want-[0-9]$
line : have-1
--
```
An error is displayed if the specified extended regular expression is
invalid.
This option and partial matching (`--partial` or `-p`) are mutually
exclusive. An error is displayed when used simultaneously.
### `refute_line`
Similarly to `refute_output`, this function helps to verify that a
command or function produces the correct output. It checks that the
unexpected line does not appear in the output (default) or in a specific
line of it. Matching can be literal (default), partial or regular
expression. This function is the logical complement of `assert_line`.
***Warning:*** *Due to a [bug in Bats][bats-93], empty lines are
discarded from `${lines[@]}`, causing line indices to change and
preventing testing for empty lines.*
[bats-93]: https://github.com/sstephenson/bats/pull/93
#### Looking for a line in the output
By default, the entire output is searched for the unexpected line. The
assertion fails if the unexpected line is found in `${lines[@]}`.
```bash
@test 'refute_line() looking for line' {
run echo $'have-0\nwant\nhave-2'
refute_line 'want'
}
```
On failure, the unexpected line, the index of its first match and the
output with the matching line highlighted are displayed.
***Warning:*** *The output displayed does not contain empty lines. See
the Warning above for more.*
```
-- line should not be in output --
line : want
index : 1
output (3 lines):
have-0
> want
have-2
--
```
If output is not longer than one line, it is displayed in *two-column*
format.
#### Matching a specific line
When the `--index <idx>` option is used (`-n <idx>` for short) , the
unexpected line is matched only against the line identified by the given
index. The assertion fails if the unexpected line equals
`${lines[<idx>]}`.
```bash
@test 'refute_line() specific line' {
run echo $'have-0\nwant-1\nhave-2'
refute_line --index 1 'want-1'
}
```
On failure, the index and the unexpected line are displayed.
```
-- line should differ --
index : 1
line : want-1
--
```
#### Partial matching
Partial matching can be enabled with the `--partial` option (`-p` for
short). When used, a match fails if the unexpected *substring* is found
in the matched line.
```bash
@test 'refute_line() partial matching' {
run echo $'have 1\nwant 2\nhave 3'
refute_line --partial 'want'
}
```
On failure, in addition to the details of literal matching, the
substring is also displayed. When used with `--index <idx>` the
substring replaces the unexpected line.
```
-- no line should contain substring --
substring : want
index : 1
output (3 lines):
have 1
> want 2
have 3
--
```
This option and regular expression matching (`--regexp` or `-e`) are
mutually exclusive. An error is displayed when used simultaneously.
#### Regular expression matching
Regular expression matching can be enabled with the `--regexp` option
(`-e` for short). When used, a match fails if the *extended regular
expression* matches the line being tested.
*Note: As expected, the anchors `^` and `$` bind to the beginning and
the end of the matched line, respectively.*
```bash
@test 'refute_line() regular expression matching' {
run echo $'Foobar v0.1.0\nRelease date: 2015-11-29'
refute_line --index 0 --regexp '^Foobar v[0-9]+\.[0-9]+\.[0-9]$'
}
```
On failure, in addition to the details of literal matching, the regular
expression is also displayed. When used with `--index <idx>` the regular
expression replaces the unexpected line.
```
-- regular expression should not match line --
index : 0
regexp : ^Foobar v[0-9]+\.[0-9]+\.[0-9]$
line : Foobar v0.1.0
--
```
An error is displayed if the specified extended regular expression is
invalid.
This option and partial matching (`--partial` or `-p`) are mutually
exclusive. An error is displayed when used simultaneously.
## Options
For functions that have options, `--` disables option parsing for the
remaining arguments to allow using arguments identical to one of the
allowed options.
```bash
assert_output -- '-p'
```
Specifying `--` as an argument is similarly simple.
```bash
refute_line -- '--'
```

# and 0 otherwise.

# All output is formatted for readability using the functions of
# `output.bash' and sent to the standard error.
#
# Fail and display the expression if it evaluates to false.

# as `[[', can be used only when executed with `bash -c'.

CC0 1.0 Universal
Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator and
subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for the
purpose of contributing to a commons of creative, cultural and scientific
works ("Commons") that the public can reliably and without fear of later
claims of infringement build upon, modify, incorporate in other works, reuse
and redistribute as freely as possible in any form whatsoever and for any
purposes, including without limitation commercial purposes. These owners may
contribute to the Commons to promote the ideal of a free culture and the
further production of creative, cultural and scientific works, or to gain
reputation or greater distribution for their Work in part through the use and
efforts of others.
For these and/or other purposes and motivations, and without any expectation
of additional consideration or compensation, the person associating CC0 with a
Work (the "Affirmer"), to the extent that he or she is an owner of Copyright
and Related Rights in the Work, voluntarily elects to apply CC0 to the Work
and publicly distribute the Work under its terms, with knowledge of his or her
Copyright and Related Rights in the Work and the meaning and intended legal
effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not limited
to, the following:
i. the right to reproduce, adapt, distribute, perform, display, communicate,
and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or likeness
depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data in
a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation thereof,
including any amended or successor version of such directive); and
vii. other similar, equivalent or corresponding rights throughout the world
based on applicable law or treaty, and any national implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention of,
applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and
unconditionally waives, abandons, and surrenders all of Affirmer's Copyright
and Related Rights and associated claims and causes of action, whether now
known or unknown (including existing as well as future claims and causes of
action), in the Work (i) in all territories worldwide, (ii) for the maximum
duration provided by applicable law or treaty (including future time
extensions), (iii) in any current or future medium and for any number of
copies, and (iv) for any purpose whatsoever, including without limitation
commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes
the Waiver for the benefit of each member of the public at large and to the
detriment of Affirmer's heirs and successors, fully intending that such Waiver
shall not be subject to revocation, rescission, cancellation, termination, or
any other legal or equitable action to disrupt the quiet enjoyment of the Work
by the public as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason be
judged legally invalid or ineffective under applicable law, then the Waiver
shall be preserved to the maximum extent permitted taking into account
Affirmer's express Statement of Purpose. In addition, to the extent the Waiver
is so judged Affirmer hereby grants to each affected person a royalty-free,
non transferable, non sublicensable, non exclusive, irrevocable and
unconditional license to exercise Affirmer's Copyright and Related Rights in
the Work (i) in all territories worldwide, (ii) for the maximum duration
provided by applicable law or treaty (including future time extensions), (iii)
in any current or future medium and for any number of copies, and (iv) for any
purpose whatsoever, including without limitation commercial, advertising or
promotional purposes (the "License"). The License shall be deemed effective as
of the date CC0 was applied by Affirmer to the Work. Should any part of the
License for any reason be judged legally invalid or ineffective under
applicable law, such partial invalidity or ineffectiveness shall not
invalidate the remainder of the License, and in such case Affirmer hereby
affirms that he or she will not (i) exercise any of his or her remaining
Copyright and Related Rights in the Work or (ii) assert any associated claims
and causes of action with respect to the Work, in either case contrary to
Affirmer's express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or warranties
of any kind concerning the Work, express, implied, statutory or otherwise,
including without limitation warranties of title, merchantability, fitness
for a particular purpose, non infringement, or the absence of latent or
other defects, accuracy, or the present or absence of errors, whether or not
discoverable, all to the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without limitation
any person's Copyright and Related Rights in the Work. Further, Affirmer
disclaims responsibility for obtaining any necessary consents, permissions
or other rights required for any use of the Work.
d. Affirmer understands and acknowledges that Creative Commons is not a
party to this document and has no duty or obligation with respect to this
CC0 or use of the Work.

*__Important:__ `bats-core` has been renamed to `bats-support`. GitHub
automatically redirects all references, e.g. submodules and clones will
continue to work, but you are encouraged to [update][github-rename]
them. Version numbering continues where `bats-core` left off.*

# bats-support
[![GitHub license](https://img.shields.io/badge/license-CC0-blue.svg)](https://raw.githubusercontent.com/ztombol/bats-support/master/LICENSE)
[![GitHub release](https://img.shields.io/github/release/ztombol/bats-support.svg)](https://github.com/ztombol/bats-support/releases/latest)
[![Build Status](https://travis-ci.org/ztombol/bats-support.svg?branch=master)](https://travis-ci.org/ztombol/bats-support)
`bats-support` is a supporting library providing common functions to
test helper libraries written for [Bats][bats].
Features:
- [error reporting](#error-reporting)
- [output formatting](#output-formatting)
See the [shared documentation][bats-docs] to learn how to install and
load this library.
If you want to use this library in your own helpers or just want to
learn about its internals see the developer documentation in the [source
files](src).
## Error reporting
### `fail`
Display an error message and fail. This function provides a convenient
way to report failure in arbitrary situations. You can use it to
implement your own helpers when the ones available do not meet your
needs. Other functions use it internally as well.
```bash
@test 'fail()' {
fail 'this test always fails'
}
```
The message can also be specified on the standard input.
```bash
@test 'fail() with pipe' {
echo 'this test always fails' | fail
}
```
This function always fails and simply outputs the given message.
```
this test always fails
```
## Output formatting
Many test helpers need to produce human readable output. This library
provides a simple way to format simple messages and key value pairs, and
display them on the standard error.
### Simple message
Simple messages without structure, e.g. one-line error messages, are
simply wrapped in a header and a footer to help them stand out.
```
-- ERROR: assert_output --
`--partial' and `--regexp' are mutually exclusive
--
```
### Key-Value pairs
Some helpers, e.g. [assertions][bats-assert], structure output as
key-value pairs. This library provides two ways to format them.
When the value is one line long, a pair can be displayed in a columnar
fashion called ***two-column*** format.
```
-- output differs --
expected : want
actual : have
--
```
When the value is longer than one line, the key and value must be
displayed on separate lines. First, the key is displayed along with the
number of lines in the value. Then, the value, indented by two spaces
for added readability, starting on the next line. This is called
***multi-line*** format.
```
-- command failed --
status : 1
output (2 lines):
Error! Something went terribly wrong!
Our engineers are panicing... \`>`;/
--
```
Sometimes, for clarity, it is a good idea to display related values also
in this format, even if they are just one line long.
```
-- output differs --
expected (1 lines):
want
actual (3 lines):
have 1
have 2
have 3
--
```
