python unit test assert exception

title: python unit test assert exception tutorial with code examples
introduction:
unit testing is a crucial part of software development, helping to ensure the reliability and correctness of your code. in python, the unittest module provides a robust framework for writing and running tests. one common scenario in testing is asserting that a specific exception is raised under certain conditions. this tutorial will guide you through using the unittest module to assert exceptions in your python unit tests with practical code examples.
in the example above, the test_assert_exception method uses assertraises to check if a valueerror is raised within the specified block of code.
here, the test_exception_message method checks if a valueerror is raised with a specific error message.
in the example above, the test passes if either a typeerror or a valueerror is raised.
conclusion:
using the unittest module in python allows you to write effective unit tests, including assertions for exceptions. by employing assertraises and context managers, you can ensure that your code behaves as expected under different error conditions. writing comprehensive unit tests with exception assertions contribute
