ContextsΒΆ
Coverage.py 5.0 can record separate coverage data for different contexts during
one run of a test suite. Pytest-cov can use this feature to record coverage
data for each test individually, with the --cov-context=test
option.
The context name recorded in the coverage.py database is the pytest test id, and the phase of execution, one of “setup”, “run”, or “teardown”. These two are separated with a pipe symbol. You might see contexts like:
test_functions.py::test_addition|run
test_fancy.py::test_parametrized[1-101]|setup
test_oldschool.py::RegressionTests::test_error|run
Note that parameterized tests include the values of the parameters in the test id, and each set of parameter values is recorded as a separate test.
