argparse和unittest python
问题内容：
我正在使用argparse处理命令行参数。代码运行正常。但是，一旦我在主体中添加unittest.main（），它就无法正常工作。
我正进入（状态：
I am here
option -i not recognized
Usage: testing.py [options] [test] [...]
Options:
-h, --help Show this message
-v, --verbose Verbose output
-q, --quiet Minimal output
-f, --failfast Stop on first failure
-c, --catch Catch control-C and display results
-b, --buffer Buffer stdout and stderr during test runs
Examples:
testing.py - run default set of tests
testing.py MyTestSuite - run suite 'MyTestSuite'
testing.py MyTestCase.testSomething - run MyTestCase.testSomething
testing.py MyTestCase - run all 'test*' test methods
in MyTestCase
我这样做是这样的：
if __name__ == "__main__":
print "I am here"
unittest.main()
问题答案：
采用
runner = unittest.TextTestRunner()
itersuite = unittest.TestLoader().loadTestsFromTestCase(MyTestClass)
runner.run(itersuite)
代替：
unittest.main()
