关于jenkins集成python的单元测试

最近在研究jenkins的集成，然后想把自己写的python工具也用jenkins集成一下

废话少说，来看结构

        while key:
            cnt += 1
            key &= key -1
        return cnt

def main():
    s = Sparking()
    s.get_num_of_zero(32, 5)

if __name__ == '__main__':
    main()`

代码上次svn，然后配置jenkins；jenkins的安装就不介绍了，网上一搜一大片；jenkins里先安装好Cobertura Plugin插件，用来显示代码覆盖率的

1、创建job

2、配置svn

3、设置触发器

4、构建 (前提需要安装pytest-cov)

5、构建后展示report

6、保存、应用即可

7、执行结果和报告

console ：

报告截图：

PS：补充下在virtualenv下的执行

从第4步开始

4、构建这里需要先安装pytest-html 和pytest-cov ，然后添加SHELL

plain 复制代码

`pip freeze > ./requirements.txt
if [ ! -d "venv" ]; then
    virtualenv -p /usr/bin/python venv
fi

. venv/bin/activate
pip install -r requirements.txt
cd sparking
py.test tests/test_sparking.py --html=pytest_result.html --cov=sparking --cov-report=xml`

这里使用了pytest-html生成的报告更好看一些

后面基本一致，注意生成报告的路径要配置正确，看下结果：

最后感谢每一个认真阅读我文章的人，礼尚往来总是要有的，这些资料，对于【软件测试】的朋友来说应该是最全面最完整的备战仓库，虽然不是什么很值钱的东西，如果你用得到的话可以直接拿走：

这些资料，对于【软件测试】的朋友来说应该是最全面最完整的备战仓库，这个仓库也陪伴上万个测试工程师们走过最艰难的路程，希望也能帮助到你！
