"""A matcher that tests if protos meet MathOpts definition of equivalence.
|
|
|
|
This is designed to be used with unittest.mock, which is canonical for mocking
|
|
in Google Python (e.g., see stubby codelabs).
|
|
|
|
See normalize.py for technical definitions.
|
|
|
|
The matcher can be used as a replacement for
|
|
google3.net.proto2.contrib.pyutil.matcher.Proto2Matcher
|
|
but supports a much smaller set of features.
