GitLab CI/CD使用经验，来自于莫纳什大学的考试任务解析

CI/CD简介

CI/CD的作用在于自动化和加速软件开发、测试和交付流程，通过持续集成确保代码协同工作和质量，通过持续交付降低风险，使每次代码变更都能够快速、高质量地交付到生产环境，从而提高软件开发效率、质量和协作。

作业要求

学校给出一个售货系统的代码，需要学生对于代码进行构建CI/CD（flake8，mypy，pycodestyle，pydocstyle，pylint），并且使用Python完善软件测试（test）。

解析方案

在构建CI/CD管道时，在使用配置文件创建静态分析时，我最初没有区分地将所有阶段合并在一起。在后来的过程中，我通过为每个阶段使用相同的阶段名称来解决这个问题。当测试没有被代码纠正时发生的测试用例。
Below is my code:

stages:- Static Analysis - Testflake8:stage: Static Analysisscript:- pip install flake8- flake8 megamart.pyallow_failure: truemypy:stage: Static Analysis  script:- pip install mypy- mypy megamart.pyallow_failure: truepycodestyle:stage: Static Analysisscript: - pip install pycodestyle- pycodestyle megamart.py allow_failure: truepydocstyle:stage: Static Analysisscript:- pip install pydocstyle- pydocstyle megamart.pyallow_failure: truepylint:stage: Static Analysisscript:- pip install pylint- pylint megamart.pyallow_failure: truetesting:stage: Testscript:- python -m unittest test_megamart.pyallow_failure: false

在修改完测试用例后可以登录你的GitLab可以看到你的测试结果已经通过，但是你的代码风格分析产生一些错误异常

分析代码风格产生异常的原因

PyCodeStyles

使用Python绘制一个柱状图来查看代码风格产生异常的错误代码

接下来根据每一个错误给出解决错误的方式
D200: One-line docstring should fit on one line with quotes (found 4):
这个错误只需要在导入一个模块的时候加上备注写入对于模块的描述就可以解决这个问题，下面是对比：
