------------------------------
Summary: Add new matcher to check output file content for
WordCountIT and WindowedWordCountIT
Key: BEAM-3810
URL: https://issues.apache.org/jira/browse/BEAM-3810
Project: Beam
Issue Type: Test
Components: testing
Reporter: Mark Liu
Assignee: Mark Liu
Test use case like
[https://github.com/apache/beam/pull/4755#discussion_r173254182] shows that
verify lines of output for integration test makes the validation and debugging
easier than simple verify checksum. We'd like to add a new matcher (like
FileContentMatcher) to very lines given expected files.
This matcher can be applied to ITs that already use FileChecksumMatcher (etc.
WordCountIT and WindowedWordCountIT).
