pytest运行结果解析及其改造

简介：场景假设 - 当运行pytest完成后，需要针对运行的结果进行即时的反馈，打印 PASS 或者 FAIL，及其运行失败的原因，最后将结果推送给消息机器人。

历史攻略：

pytest+allure安装和使用

pytest：并行和并发运行用例

python：消息推送 - 企业微信机器人推送

让你的pytest日志更有序：配置和使用技巧

Python配置与测试利器：Hydra + pytest的完美结合

Playwright - 04：pytest并行、并发、运行浏览器兼容性测试

分析源码：

pytest.main()的执行结果为枚举，依次为以下6种情况。

@final
class ExitCode(enum.IntEnum):
    #: Tests passed.
    OK = 0
    #: Tests failed.
    TESTS_FAILED = 1
    #: pytest was interrupted.
    INTERRUPTED = 2
    #: An internal error got in the way.
    INTERNAL_ERROR = 3
    #: pytest was misused.
    USAGE_ERROR = 4
    #: pytest couldn't find tests.
    NO_TESTS_COLLECTED = 5

根据结果进行判断输出，使用艺术字模块打印 PASS 或者 FAIL即可。

    if result == 0:
        print(Fore.GREEN + Back.BLACK + Style.BRIGHT + f.renderText('PASS'))
    elif result == 1:
        print(Fore.RED + Back.BLACK + Style.BRIGHT + f.renderText('FAIL'))
    else:
        pass
    # step-2：auto report json data，zip to allure-html
    os.system("allure serve report")
    # os.popen("allure serve report")
