Foreword
python unittest is carrying unit testing framework, similar to Junit (Java unit testing framework). Support for automated testing, you can write test pre & post-conditions, and can generate a batch run test cases and test reports.
Use unittest subject to the following points:
1, to be used when introducing unittest module
2, write a test class, and inherit unittest.TestCase
3, test case name begins with test (unittest will automatically be placed in the beginning of the test method test cases focus)
4, assertion assertion format required unittest
Usage Profile
A, front & rear
Front and rear of the front and rear class, a function of: before and after the two kinds of classification set unittest
Opposed front and rear class:
- Perform tests at the beginning of class, app automation mainly used to start the app - class front; web browser automation is mainly used to start the drive, set up to maximize the browser window, open a default url: setUpClass.
- tearDownClass: Rear class - class execution at the end of the test, mainly for closing the browser app & answer
Before and after the function set:
- setUp: Pre - Functions performed at the start of the test function, may be used to write some embodiments preconditions (e.g., operation log, etc.)
- tesrDown: Post - Functions performed at the end of the test function, may be used to write some embodiments postcondition (e.g. test data initialization)
Simple example:
Remarks:
setUpClass & tearDownClass must use decorator @classmethod
Second, write test cases
1, test cases need to test at the beginning
2, unittest common assertion
unittest commonly asserted as follows:
- assertEqual (arg1, arg2, msg = None): verification parameter equal
- assertNotEqual (arg1, arg2, msg = None): authentication parameter ranges
- assertTrue (expr, msg = None): verification parameter ture
- assertFalse (expr, msg = None): false verification parameter
- assertIsNone (expr, msg = None): verification parameter None
- assertIsNotNone (expr, msg = None): Non-verification parameter None
- assertIn (arg1, arg2, msg = None): Verify comprising arg1 arg2
Simple example (ding-dong app to search for the car plus an example):
Third, the implementation of test cases
By unittest.main () implementation of test cases
Example:
