Pytest 文件执行
在本章中,我们将学习如何执行单个测试文件和多个测试文件。我们已经有一个测试文件 test_square.py 创建的。创建一个新的测试文件 test_compare.py 使用以下代码:
def test_greater(): num = 100 assert num > 100 def test_greater_equal(): num = 100 assert num >= 100 def test_less(): num = 100 assert num < 200
现在要从所有文件(这里有 2 个文件)运行所有测试,我们需要运行以下命令:
pytest -v
上面的命令将从两者运行测试 test_square.py and test_compare.py .输出将如下生成:
test_compare.py::test_greater FAILED test_compare.py::test_greater_equal PASSED test_compare.py::test_less PASSED test_square.py::test_sqrt PASSED test_square.py::testsquare FAILED ================================================ FAILURES ================================================ ______________________________________________ test_greater ______________________________________________ def test_greater(): num = 100 > assert num > 100 E assert 100 > 100 test_compare.py创建的。创建一个新的测试文件 AssertionError _______________________________________________ testsquare _______________________________________________ def testsquare(): num = 7 > assert 7*7 == 40 E assert (7 * 7) == 40 test_square.pytest_compare.py AssertionError =================================== 2 failed, 3 passed in 0.07 seconds ===================================
要从特定文件执行测试,请使用以下语法:
pytest <filename> -v
现在,运行以下命令:
pytest test_compare.py -v
上面的命令将只从文件中执行测试 测试比较.py。 我们的结果将是:
test_compare.py::test_greater FAILED test_compare.py::test_greater_equal PASSED test_compare.py::test_less PASSED ============================================== FAILURES ============================================== ____________________________________________ test_greater ____________________________________________ def test_greater(): num = 100 > assert num > 100 E assert 100 > 100 test_compare.py创建的。创建一个新的测试文件 AssertionError ================================= 1 failed, 2 passed in 0.04 seconds =================================
