python unittest套件加载用例时，出现No tests were found，Empty test suite

• 错误信息：

之前运行好好的脚本，突然报No tests were found，Empty test suite,详情错误信息如下所示：

Launching pytest with arguments loanlaterOfflineExtend.py::LoanlaterOfflineExtend::test_ConfirmLoanOffline3 in D:scriptpy_jjdTestCase

============================= test session starts =============================

• 解决方法：个人习惯，类似场景用例命名规则在后面用数字加以区别例如test_a1、test_a2、test_a3，python之前的版本是支持这样设计的，但现在认为这样的为重复用例名

将用例名从 test_a1、test_a2、test_a3 改test_aA、test_aB、test_aC 如下图所示就可以过了：
