[] Using Python + unittest test suite TestSuite add only one use case, but performed all use cases, turned out to be PyCharm configuration issues

Today in learning TestSuite test suite, a total of three test cases, the test suite TestSuite added only one, but the implementation of all three use cases.

1. Open: Run Run -> Edit configurations Structure Edit -> New Python + 1 arranged on it. (Do not Python tests)

  

2.Script add the path. Do not add directly to "OK", it should be also possible.

3. Re-run, should be on it. (Execution, you can see here, are not you just add configuration)
