There is a Python automation script for the identification and manipulation of common elements, which goes on to talk about Python class inheritance, its third unittest framework, and the application of the report collection package Htmltestrunner.Let's go straight to the code.Applications of UnitTest and Htmltestrunne

Python unit test unittest instance details, pythonunittest This example describes how to use unittest in python unit test. Share it with you for your reference. The specific analysis is as follows: Unit testing, as a developer of any language, should be necessary, because when you come back to debug your complex progra

1 Test Case TestCaseThe most basic component of a software test is the test case , which Pyunit uses the TestCase class to represent the test case and requires that all classes used to perform the test must inherit from the class. The test code implemented by the TestCase subclass should be self-contained, which means that the test case can run either individually or with other test case constituent collections.TestCase is considered a running entity of the test unit in the Pyunit test framework

Python + Selenium notes (3): Use unittest, seleniumunittest # An error may occur when the network is slow. (1) Preface Selenium WebDriver is an API set for automated browser testing. It provides many features for automated interaction with browsers, and these APIs are mainly used to test Web programs. If Selenium WebDriver is used only, we cannot implement the pre-conditions and post-Conditions for executin

Python + Selenium notes (4): unittest Test Suite and seleniumunittest (1)Test SuiteTest Suite A test suite is a set of multiple tests or test cases. It is a set of tests created for the functions and modules of the tested program, the test cases in a test suite are executed together. Using the TestSuites feature of unittest, you can combine different tests into

Some experience about UnitTest module, mainly is the example of crossing net, add a little own understanding, official website address:https://docs.python.org/3.6/library/unittest.htmlThe UnitTest module is a Python unit test framework that supports automated testing, and all use cases share setup and teardown code, and test cases can be aggregated into test sets

The first five sections mainly introduce the environment construction and the use of the requests library, which can be used to send the interface request. But how to manage the interface case? Returns how the results are automatically verified? This is not possible with the above five sections, so from this section we have introduced the Python Unit Test framework unittest, which handles batch use case man

=D.empty - the if __name__=='__main__': +Unittest.main ()Attention:Unit testing can effectively test the behavior of a program module and is a confidence guarantee for future refactoring code.Test cases for unit tests overwrite common input combinations, boundary conditions, and exceptions.Unit test code is very simple, if the test code is too complex, then the test code itself may have a bug.Unit testing does not mean that the program is not a bug, but not through the program must have a bug.
