I'm wondering is there a way to specify more than 1 test file to run when using python coverage config (.coveragerc) file.
If not from a config file, maybe it is possible when running from command line?
At the moment, for 3 different unit tests files I'm using:
coverage run test1
coverage run -a test2
coverage run -a test3
Can it be any shorter? Thanks
Edit (2017-09-25): As @ned-batchelder says in the comments, prefer pytest over nose if starting a new project, as nose is unmaintained.
By taking a look at Coverage documentation, it looks like that the only mode that coverage supports is running a specific module with each command.
You could use a testing framework, such as nose pytest, to run all your tests, and report the success/failure rate and the total coverage.
pytest1) Install pytest, coverage, and pytest-cov
pip install pytest
pip install coverage
pip install pytest-cov
2) Run the pytest commmand, using the --cov flag for every module or package whose coverage you need measured. For example:
pytest --cov=foo --cov=bar
Sample output:
Name Stmts Miss Cover Missing
--------------------------------------
bar.py 3 1 67% 5
foo.py 6 2 67% 9-11
--------------------------------------
TOTAL 9 3 67%
pytest will find your tests if they match the pattern test_*.py (or others, more info here).
nose1) Install nose and coverage
pip install nose
pip install coverage
2) Run the nosetests command, with the --with-coverage flag
nosetests --with-coverage
Sample output (when having a single module foo.py):
Name Stmts Miss Cover
----------------------------
foo.py 6 2 67%
----------------------------------------------------------------------
Ran 1 test in 0.008s
OK
nosetests can automatically find your tests using some heuristics. For example, if you put your tests in filenames that start with test, and create your testcases by inheriting from unittest.TestCase, nosetests will find them. More info here.
