Pytest运行测试子集
一、单个目录运行
运行单个目录下的所有测试，以目录作为pytest的参数即可
(venv_dome) F:\TESTING\BlogPosts\ReadPytest>pytest ch2 --tb=no
================================================================================== test session starts ===================================================================================
collected 9 items
ch2\test_eight.py .. [ 22%]
ch2\test_nine.py .. [ 44%]
ch2\test_seven.py .. [ 66%]
ch2\test_six.py . [ 77%]
ch2\test_ten.py .. [100%]
=================================================================================== 9 passed in 0.12s ====================================================================================
二、单个测试文件/模块运行
运行单个文件里的全部测试，以路径加文件名作为pytest参数即可
(venv_dome) F:\TESTING\BlogPosts\ReadPytest>pytest ch2/test_ten.py
================================================================================== test session starts ===================================================================================
collected 2 items
ch2\test_ten.py .. [100%]
=================================================================================== 2 passed in 0.06s ====================================================================================
三、单个测试函数运行
运行单个测试函数，只需要在文件后面添加 ：： 符号和函数名即可
(venv_dome) F:\TESTING\BlogPosts\ReadPytest>pytest -v ch2/test_six.py::test_01_six_pass
================================================================================== test session starts ===================================================================================
collected 1 item
ch2/test_six.py::test_01_six_pass PASSED [100%]
=================================================================================== 1 passed in 0.04s ====================================================================================
四、运行单个测试类
测试类用于将某些相识的测试函数/用例组合在一起
class TestTen:
expected_result = [i for i in range(1, 5)]
def test_01_ten_pass(self):
actual_result = tuple(i for i in range(1, 5))
assert actual_result != self.expected_result
def test_02_ten_fail(self):
actual_result = tuple(i for i in range(1, 5))
assert actual_result != self.expected_result
要运行该类，在文件后面加上 : : 符号和类名（与运行单个测试函数类似）
(venv_dome) F:\TESTING\BlogPosts\ReadPytest>pytest -v ch2/test_ten.py::TestTen
================================================================================== test session starts ===================================================================================
collected 2 items
ch2/test_ten.py::TestTen::test_01_ten_pass PASSED [ 50%]
ch2/test_ten.py::TestTen::test_02_ten_fail PASSED [100%]
=================================================================================== 2 passed in 0.03s ====================================================================================
五、单个测试类中的测试方法/用例
不希望运行测试类中的所有测试方法/用例，只想指定运行其中的一个，可以在文件后面添加 : : 符号和方法名即可
(venv_dome) F:\TESTING\BlogPosts\ReadPytest>pytest -v ch2/test_ten.py::TestTen::test_01_ten_pass
================================================================================== test session starts ===================================================================================
collected 1 item
ch2/test_ten.py::TestTen::test_01_ten_pass PASSED [100%]
=================================================================================== 1 passed in 0.02s ====================================================================================
六、用测试名划分测试集合
-k 选项允许一个表达式指定需要运行的测试，该表达式可以匹配测试名，表达式中可以包含 and、or、not 。
下面运行的是包含 _pass 的测试：
(venv_dome) F:\TESTING\BlogPosts\ReadPytest>pytest -v -k _pass
================================================================================== test session starts ===================================================================================
collected 16 items / 7 deselected / 9 selected
test_three.py::TestThree::test_01_three_pass XPASS [ 11%]
test_three.py::TestThree::test_03_four_pass PASSED [ 22%]
test_two.py::test_run_pass SKIPPED [ 33%]
ch1/test_five.py::TestFive::test_01_five_pass PASSED [ 44%]
ch2/test_eight.py::TestEight::test_01_eight_pass PASSED [ 55%]
ch2/test_nine.py::TestNine::test_01_nine_pass PASSED [ 66%]
ch2/test_seven.py::TestSeven::test_01_seven_pass PASSED [ 77%]
ch2/test_six.py::test_01_six_pass PASSED [ 88%]
ch2/test_ten.py::TestTen::test_01_ten_pass PASSED [100%]
================================================================= 7 passed, 1 skipped, 7 deselected, 1 xpassed in 0.28s ==================================================================
下面运行的是包含 _pass和_run 的测试
(venv_dome) F:\TESTING\BlogPosts\ReadPytest>pytest -v -k "_pass and _run"
================================================================================== test session starts ===================================================================================
collected 16 items / 15 deselected / 1 selected
test_two.py::test_run_pass SKIPPED [100%]
=========================================================================== 1 skipped, 15 deselected in 0.07s ============================================================================
下面运行的是不包含_pass和_run 的测试
(venv_dome) F:\TESTING\BlogPosts\ReadPytest>pytest -v -k "_pass and not _run"
================================================================================== test session starts ===================================================================================
collected 16 items / 8 deselected / 8 selected
test_three.py::TestThree::test_01_three_pass XPASS [ 12%]
test_three.py::TestThree::test_03_four_pass PASSED [ 25%]
ch1/test_five.py::TestFive::test_01_five_pass PASSED [ 37%]
ch2/test_eight.py::TestEight::test_01_eight_pass PASSED [ 50%]
ch2/test_nine.py::TestNine::test_01_nine_pass PASSED [ 62%]
ch2/test_seven.py::TestSeven::test_01_seven_pass PASSED [ 75%]
ch2/test_six.py::test_01_six_pass PASSED [ 87%]
ch2/test_ten.py::TestTen::test_01_ten_pass PASSED [100%]
======================================================================= 7 passed, 8 deselected, 1 xpassed in 0.09s =======================================================================
下面运行是包含_pass或_run 的测试
(venv_dome) F:\TESTING\BlogPosts\ReadPytest>pytest -v -k "_pass or _run"
================================================================================== test session starts ===================================================================================
collected 16 items / 6 deselected / 10 selected
test_three.py::TestThree::test_01_three_pass XPASS [ 10%]
test_three.py::TestThree::test_03_four_pass PASSED [ 20%]
test_two.py::test_run_pass SKIPPED [ 30%]
test_two.py::test_run_fail PASSED [ 40%]
ch1/test_five.py::TestFive::test_01_five_pass PASSED [ 50%]
ch2/test_eight.py::TestEight::test_01_eight_pass PASSED [ 60%]

================================================================= 8 passed, 1 skipped, 6 deselected, 1 xpassed in 0.09s ==================================================================
上面简介了如何指定测试文件、目录、类、函数/用例，如何利用-k选项选择部分测试，以上总结如有不当之处，还请提出疑义，后面会加以修改，多谢阅读！
始终相信你的努力，终会在某一天得到回报！！！
