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。 我们已经创建了一个测试文件 test_square.py。 使用以下代码创建一个新的测试文件 test_compare.py −
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
上述命令将从 test_square.py 和 test_compare.py 运行测试。 将生成如下输出 −
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:3: AssertionError _______________________________________________ testsquare _______________________________________________ def testsquare(): num = 7 > assert 7*7 == 40 E assert (7 * 7) == 40 test_square.py:9: 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
上述命令将仅从文件 test_compare.py 执行测试。 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:3: AssertionError ================================= 1 failed, 2 passed in 0.04 seconds =================================
