@pytest.mark 其他用法_pytest.mark.testcase()用法-优快云博客

本文详细介绍了一个使用pytest进行单元测试的例子，包括多个测试用例的编写、断言的使用、测试标记、条件跳过、预期失败和异常处理。通过具体代码展示了如何组织和执行测试，以确保代码质量和功能正确性。

# 1.跳过这个测试
# @pytest.mark.skip(reason = "跳过这个测试")
# 2.有条件的跳过这个测试
# @pytest.mark.skipif(sys.version_info >= (3,6), reason = "有条件的跳过这个测试")
# 3.strict=True以确保XPASS（意外通过）时，测试的记录为失败
# @pytest.mark.xfail(strict = True)
# 4.标记对故障的期待，如果测试失败且未在加注中提及，则将报告为常规故障
# @pytest.mark.xfail(sys.version_info >= (3, 6), reason = "python3.6 api changes")
# 5.raises参数中指定单个异常或异常组,如果错误类型是别的，就会打印错误
# @pytest.mark.xfail(raises = RuntimeError)
