自动化-unitest的加载方式

discover(start_dir,pattern='test*.py',top_level_dir=None)

找到指定目录下所有测试模块，并可递归查到子目录下的测试模块，只有匹配到文件名才能被加载。如果启动的不是顶层目录，那么顶层目录必须单独指定。

• • start_dir：要测试的模块名或测试用例目录
  • pattern='test*.py'：表示用例文件名的匹配原则。此处匹配文件名以“test”开头的“.py”类型的文件
  • top_level_dir=None：测试模块的顶层目录

通过testLoader方式

• unittest.TestLoader().loadTestsFromTestCase(类名)
• unittest.TestLoader().loadTestsFromMoudule(模块名)
• unittest.TestLoader().loadTestsFromName(方法名)
• unittest.TestLoader().loadTestsFromNames(方法名，复数形式)

if __name__ == "__main__":
    # loadTestsFromTestCase(class name )
    # loadTestsFromName('AutoTest.AutoTest1') module.class.testcase
    # loadTestsFromName('AutoTest.AutoTest1') module.class
    # loadTestsFromModule(test1) module
    suite_1 = unittest.TestLoader().loadTestsFromName('AutoTest.AutoTest1')
    suite_2 = unittest.TestLoader().loadTestsFromModule(test1)
    suite_3 = unittest.TestLoader().loadTestsFromNames(['AutoTest.AutoTest1.test_1','AutoTest.AutoTest1.test_2'])
    suite_4 = unittest.TestLoader().loadTestsFromTestCase(AutoTest2)
    suite = unittest.TestSuite(suite_3)
    run = unittest.TextTestRunner()
    run.run(suite)
