I agree that the function names here are a bit confusing - in essence this
function locates a single test file, while the function in the next code line
`getFilesInFolder` collects files that start with `test_`, thus the main test
file `run_all_tests.py` will be filtered and not be included.
So, in order to be more readable and robust, I changed the
`getFilesInFolder` to receive one more argument of `excludes` and call it with
the main test file in the `excludes` argument.
> Python API for streaming applications
> -------------------------------------
>
> Key: FLINK-5886
> URL: https://issues.apache.org/jira/browse/FLINK-5886
> Project: Flink
> Issue Type: New Feature
> Components: Python API
> Reporter: Zohar Mizrahi
> Assignee: Zohar Mizrahi
>
> A work in progress to provide python interface for Flink streaming APIs. The
> core technology is based on jython and thus imposes two limitations: a. user
> defined functions cannot use python extensions. b. the python version is 2.x
> The branch is based on Flink release 1.2.0, as can be found here:
> https://github.com/zohar-pm/flink/tree/python-streaming
> In order to test it, someone can use IntelliJ IDE. Assuming IntelliJ was
> setup properly (see:
> https://ci.apache.org/projects/flink/flink-docs-release-1.3/internals/ide_setup.html),
> one can run/debug {{org.apache.flink.python.api.PythonStreamBinderTest}},
> which in return will execute all the tests under
> {{/Users/zohar/dev/pm-flink/flink-libraries/flink-python/src/test/python/org/apache/flink/python/api/streaming}}
