PYTHON

run multiple test cases pytest

@pytest.mark.parametrize("input, expected", [
 (1, True),
 (2, True)
])
def test_check_value(input, expected):
  assert input > 0 == expected

run only few test cases in pytest

py.test tests_directory/foo.py tests_directory/bar.py -k 'test_001 or test_some_other_test'

how to group multiple test in pytest

# content of test_class.py
class TestClass:
    def test_one(self):
        x = "this"
        assert "h" in x

    def test_two(self):
        x = "hello"
        assert hasattr(x, "check")

python pytest use same tests for multiple modules

def pytest_addoption(parser):
    parser.addoption("--libname", action="append", default=[],
                     help="name of the tested library")

    
def pytest_generate_tests(metafunc):
    if 'libname' in metafunc.fixturenames:
        metafunc.parametrize("libname", metafunc.config.option.libname)

        
def test_import(libname):
    import importlib
    tested_library = importlib.import_module(libname)
    # asserts...
