Unittest system (4) test suite

In the previous section, we shared principles, assertions, and implementations. This time we share the test suite.

Test suites, which we use to organize test runs. So how do you do that

def suite():
    suite = unittest.TestSuite()
    suite.addTest(TestDemo('testone'))
    suite.addTest(TestDemo('testtwo'))
    return suite
​
if __name__ == '__main__':
    runner = unittest.TextTestRunner()
    runner.run(suite())

So, we’ve organized our test suite, and we’ve added two use cases. Then we use textTestRunner to execute the use case, and we look at the result

In fact, we can also organize our test suites by folders. We can duplicate the previous test case.

Then we have two test case files, so how do we organize our test suite by folder loading?

def suite():
    import  os
    path=os.getcwd()
    suite=unittest.TestLoader().discover(path, pattern='test*.py', top_level_dir=None)
    return suite
​
if __name__=="__main__":
    runner = unittest.TextTestRunner()
    runner.run(suite())

It’s really simple, we just need to load from TestLoader. Matches the py file starting with test and assembles the test suite. We then instantiate the TextTestRunner to execute the test suite, and let’s look at the results

If we need to get the number of test cases for the suite during testing, we can do this directly:

Print (suit.countTestCases ())

In addition to the way the test suite is loaded above, we can also load it as follows.

def suite():
    suit=unittest.TestSuite()
    suit.addTests([TestDemo('testone'),TestDemo('testtwo')])
    return suit
​
if __name__=="__main__":
    runner = unittest.TextTestRunner()
    runner.run(suite())

The result of execution is the same

There are other ways:

def suite(): suite = unittest.TestSuite() suite.addTests(unittest.TestLoader().loadTestsFromTestCase(TestDemo)) return suite if __name__=="__main__": suitone=suite() name= unittest.textTestRunner () name.run(suitone) def suite(): suite = unittest.TestSuite() suite.addTests(unittest.TestLoader().loadTestsFromName("testdemoone.TestDemo")) return suite if __name__=="__main__": suitone=suite() name=unittest.TextTestRunner() name.run(suitone)

The results of both of the above methods are as follows

We can also configure the presentation details at execution time.

suitone=suite()
name=unittest.TextTestRunner(verbosity=2)
name.run(suitone)

The result shows detailed information
