9.7 UI层的自动化测试

一般来说，UI层的自动化测试是通过工具或编写脚本的方式来模拟手工测试的过程，通过运行脚本来执行测试用例，从而模拟人工对软件的功能进行验证。

PyQt是Qt框架的Python语言实现，对于单元测试，Python可以使用它内部自带的单元测试模块unittest。对于模拟手工操作，PyQt可以使用它内部的测试模块QTest。

9.7.1 手工测试与自动化测试

特点总结：

手工测试由人手工去执行测试用例;自动化测试由程序代替人去执行测试用例。
手工测试非常消耗时间，持续进行手工测试会使测试人员感到疲惫;自动化测试可以代替一部分机械重复的手工测试。
手工测试永远无法被自动化测试取代。在整个软件开发周期中，手工测试发现 Bug所占的比例大，大约为80%;而自动化测试只能发现大约20%的 Bug。
手工测试适合测试业务逻辑;自动化测试适合进行回归测试。回归测试用于测试已有功能，而不是新增功能。自动化测试有利于测试项目底层的细节，比如可以测试出软件的崩溃、API的错误返回值、业务逻辑异常和软件的内存使用等。

9.7.4 运行测试用例

默认执行所有的测试用例
按照指定顺序执行测试用例

9.7.5 生成测试报告

使用HTMLTestRunner生成测试报告。

HTMLTestRunner.py

"""
A TestRunner for use with the Python unit testing framework. It
generates a HTML report to show the result at a glance.The simplest way to use this is to invoke its main method. E.g.import unittestimport HTMLTestRunner... define your tests ...if __name__ == '__main__':HTMLTestRunner.main()For more customization options, instantiates a HTMLTestRunner object.
HTMLTestRunner is a counterpart to unittest's TextTestRunner. E.g.# output to a filefp = file('my_report.html', 'wb')runner = HTMLTestRunner.HTMLTestRunner(stream=fp,title='My unit test',description='This demonstrates the report output by HTMLTestRunner.')# Use an external stylesheet.# See the Template_mixin class for more customizable optionsrunner.STYLESHEET_TMPL = '<link rel="stylesheet" href="my_stylesheet.css" type="text/css">'# run the testrunner.run(my_test_suite)------------------------------------------------------------------------
