When a mock is generated with the flag enabled, it introduces the
following changes:
- Does not panic on calling the method without a mock implementation.
- Return zero values iff the implementation is not provided and the
method has return parameters.

This reverts commit f76652f379.
Go test no longer picks up the tests when run from the project root.
$ go test -v ./...
? github.com/matryer/moq [no test files]
testing: warning: no tests to run
PASS
ok github.com/matryer/moq/example (cached) [no tests to run]

Migrating to Go modules needs special handling for fake modules such as
github.com/matryer/buildconstraints.
While extracting the method and parameters from the method signature,
only check and apply the variadic flag for the input parameters and not
for the return arguments.
Issue details:
For an interface with variadic arguments and slice return type, moq was
generating an invalid mock:
type I interface {
Func(params ...interface{}) []byte
}
// ...
type IMock struct {
// FuncFunc mocks the Func method.
FuncFunc func(params ...interface{}) ...byte
// calls tracks calls to the methods.
calls struct {
// Func holds details about calls to the Func method.
Func []struct {
// Params is the params argument value.
Params []interface{}
}
}
}
On attempting to generate the mock in such an instance, the command
would fail on the formatting step:
m.Mock: go/format: 35:30: expected ';', found '...' (and 3 more errors)
See https://github.com/matryer/moq/issues/124,
https://github.com/matryer/moq/pull/125.
- Support formatting output with gofmt(default) or goimports via flag.
- Introduce moq.Config struct to configure moq.Mocker instance. This
breaks backward compatibility but facilitates it in the future if and
when any features are added.
- Use golden file tests for validating formatters. Use
github.com/pmezard/go-difflib to print the diff between expected and
actual.
- Use travis build matrix to test on Windows and macOS
- Make utility func compatible with host OS. Use filepath package to
manipulate path strings for stripping $GOPATH from working directory.
- Delegate to go/build pkg for getting Go paths

When the interface that we are trying to moq is present inside the vendor
directory and the output package name is different, the import needs to be
stripped of the vendor path.
From the docs for packages.{LoadFiles, LoadSyntax} -
https://godoc.org/golang.org/x/tools/go/packages#pkg-constants
// Deprecated: LoadFiles exists for historical compatibility

If the user specifies a different package and the mock name is the same
as the interface name, the type guard comment will be of the following
format:
// Ensure, that MyInterface does implement MyInterface.
So use the $sourcePackagePrefix in the comment.
Add an additional line of code per interface to the generated mock file,
which allows the go compiler to statically check if the mock implements
the mocked interface.
I've stolen the list of "initialisms" from the golint codebase. Normally
I might try and figure out some way to bring the list in from the source
rather than just copy and paste it, since it may fall out of date in the
future. However, if you've ever followed any of the PRs in the golint
repository, you'll know any change like that would likely be rejected.
Most of this list hasn't changed in the last 4 years, so my feeling is
that it won't require many more updates for the life of this project.
