enable python coverage for subprocesses

Project description

This package installs a pth file that enables the coveragepy process_startup feature in this python prefix/virtualenv in subsequent runs.



$ virtualenv tmpenv
$ . tmpenv/bin/activate
$ pip install coverage-enable-subprocess
$ touch .coveragerc
$ export COVERAGE_PROCESS_START=$PWD/.coveragerc
$ echo 'print("oh, hi!")' >
$ python
oh, hi!

$ coverage report
Name                              Stmts   Miss  Cover
/etc/python2.6/       5      1    80%                               1      0   100%
tmpenv/lib/python2.6/        433    392     9%
TOTAL                               439    393    10%

For projects that need to cd during their test runs, and run many processes in parallel, I ensure a $TOP variable is exported, and I use this .coveragerc:

parallel = True
branch = True
data_file = $TOP/.coverage

exclude_lines =
    # Have to re-enable the standard pragma

    # we can't get coverage for functions that don't return:
    \#.*never returns
    \#.*doesn't return

    # Don't complain if tests don't hit defensive assertion code:
    ^\s*raise Impossible\b
    ^\s*raise AssertionError\b
    ^\s*raise NotImplementedError\b
    ^\s*return NotImplemented\b

    # Don't complain if tests don't hit re-raise of unexpected errors:

    # if main is covered, we're good:
show_missing = True

directory = $TOP/coverage-html

# vim:ft=dosini
