1、测试文件命名规则test_xxx.py或xxx_test.py
2、方法、测试函数命名规则test_xxx
3、测试类命名规则Testxxx并且不能带有 init 方法

-k 说明允许你使用表达式指定希望运行的测试用例如果某测试用例名是唯一的或者多个测试用例名的前缀和后缀相同就可以使用表达式快速定位如果你想执行的测试用例名字需包含login_01就可以这么写pytest.main([-v, -k, login_01])如果你想执行的测试用例名字需包含login_01和login_03就可以这没写pytest.main([-v, -k, login_01 or login_03])

-x 说明正常情况下pytest会运行每一个搜索到的测试用例如果某个测试函数被断言失败或者触发了外部异常则该测试用例的运行就会停止pytest将其标记为失败后会继续运行下一个测试用例。通常这就是我们期望的运行模式但是在debug时我们希望遇到失败时立即停止整个会话这时-x就派上用场了。
