Josh Rosen commented on SPARK-7721:
-----------------------------------
If we just want to be able to view the coverage reports for individual builds,
we can probably hook {{coverage.py}} into the build and rig it so that each
Python process + test run logs its coverage data to a separate file. Given
these files, I think it's possible to have {{coverage.py}} generate a combined
coverage report. Maybe we could attach / serve these combined HTML reports
from Jenkins.
If we want to be able to compare coverage across builds, we could look into
setting up an integration with Coveralls (coveralls.io), but we might run into
issues with being unable to obtain the right GitHub permissions from Apache.
We could also investigate Sonar.

> Would be great to have test coverage report for Python. Compared with Scala,
> it is tricker to understand the coverage without coverage reports in Python
> because we employ both docstring tests and unit tests in test files.
