unittest 统计测试执行case总数，成功数量，失败数量，输出至文件，生成一个简易的html报告带饼图-编程知识

这是一个Python的单元测试框架的示例代码，主要用于执行测试用例并生成测试报告。其中，通过unittest模块创建主测试类MainTestCase，并加载其他文件中的测试用例，统计用例的执行结果并将结果写入文件，最后生成一个简单的测试报告html页面。

在执行测试时，可以根据需要添加更多的测试文件和测试用例，在自定义CustomTextTestResult类中重写addSuccess和addFailure方法，获取用例的执行结果，并在统计成功和失败的用例数量时进行累加。将用例执行成功和失败的信息分别保存到success_cases和failure_cases列表中，最后将结果写入文件。

在生成测试报告时，利用HTML和CSS语言生成一个表格结构的页面，并将测试结果以文本和图表的形式展示出来。在页面中使用了一些JavaScript代码来计算成功和失败的百分比，并将其以饼状图的形式呈现出来。最终，将html代码写入到文件中，生成测试报告。
