"""Tests that checked-in file(s) match the contents of generated file(s).
The resulting test will verify that all output files exist and have the
correct contents. If the test fails, it can be invoked with --fix to
bring the checked-in files up to date.
Args:
name: Name of the rule.
outs: the checked-in files that are copied from generated files.
generated_pattern: the pattern for transforming each "out" file into a
generated file. For example, if generated_pattern="generated/%s" then
a file foo.txt will look for generated file generated/foo.txt.
target_files: A glob representing all of the files that should be
covered by this rule. Files in this glob but not generated will
be deleted. (Not currently implemented in OSS).
**kwargs: Additional keyword arguments to pass through to py_test().
