> Most of our examples use assert_that to test examples:
> https://github.com/apache/incubator-beam/blob/python-sdk/sdks/python/apache_beam/examples/complete/autocomplete_test.py#L38
> Some of our examples use this pattern:
> 1) Create a path(s)
> 2) Construct fake command line arguments using these paths
> 3) Construct an argparse object to parse these flags
> 4) Do the (often trivial logic)
> 5) Write to a file
> 6) Manually open and read the file
> 7) Compare results.

> As well as being cumbersome, this obscures the core of what is being
> illustrated and tested. As many as possible tests should be updated to use
> assert_that.
