Method 1: Randomly selected tests. Long and ugly.
python -m pytest test/stress/test_performance.py::TestPerformance::test_continuous_trigger test/integration/test_config.py::TestConfig::test_valid_config
Method 2: Use Keyword Expressions.
Note: I am searching by testcase names. Same is applicable to TestClass names.
Case 1: The below will run whichever is found. Since we have used 'OR' .
python -m pytest -k 'test_password_valid or test_no_configuration'
Lets say the two above are actually correct, 2 tests will be run.
Case 2: Now an incorrect name and another correct name.
python -m pytest -k 'test_password_validzzzzzz or test_no_configuration'
Only one is found and run.
Case 3: If you want to run either all tests mentioned, or None, then use AND
python -m pytest -k 'test_password_valid and test_no_configuration'
Both will be run if correct or none.
Case 4: Run test only in one folder:
python -m pytest test/project1/integration -k 'test_password_valid or test_no_configuration'
Case 5: Run test from only one file.
python -m pytest test/integration/test_authentication.py -k 'test_password_expiry or test_incorrect_password'
Case 6: Run all tests except the match.
python -m pytest test/integration/test_authentication.py -k 'not test_incorrect_password'
Case 7: Run a test case inside a test class. This situation arises when the test case name is common and we want to run it for a particular test class only. We can combine test class and test name with keywords.
python -m pytest -k "TestClassSomeFeature and test_valid_events"
