I'm wondering if it's possible to combine coverage.xml files into 1 file to see global report in HTML output.
I've got my unit/functional tests running as 1 command and integration tests as the second command. That means my coverage for unit/functional tests are overridden by unit tests.
That would be great if I had some solution for that problem, mainly by combining those files into 1 file.
You can't combine .xml files, but you can combine the raw data files. Your workflow would look like this:
$ COVERAGE_FILE=.coverage_func coverage run the_functional_tests.py
$ COVERAGE_FILE=.coverage_inte coverage run the_integration_tests.py
$ coverage combine
$ coverage xml
I found a different solution. I used combine feature (read here)
So I run my coverage like: coverage run -p and then I do coverage combine.
That's all. It generates 1 combined report.
You can achieve same result by using appending option. Suppose you ran the coverage on three python scripts.After first coverage use -a for appending.
coverage run first.py
coverage run -a second.py
coverage run -a third.py
Print the report
coverage report -m
Output:Report
Name Stmts Miss Cover Missing
----------------------------------------------
first.py 97 1 99% 95
second.py 1 0 100%
third.py 10 0 100%
----------------------------------------------
TOTAL 108 1 99%
If your source code is in a directory called my_project, you can also do this if you have included pytest and pytest-cov in your virtual environment:
pytest --cov-report html --cov=my_project unit_tests
pytest --cov-report html --cov=my_project --cov-append functional_tests
The --cov-append will add the functional test coverage info to the coverage file that was created when you ran the unit tests.
Use -a option with coverage run command. eg : coverage run -a test1.py This will append the results to existing coverage file, verify the same by doing coverage report
