This can be used inside the body of the with statement to perform various checks. So unittest can be considered pretty flexible when it comes to test case execution. The framework implemented by unittest supports fixtures, test suites, and a test runner to enable automated testing for your code. One of the recommendations when writing well designed applications is to separate concerns. Now change to the Tests directory and run the regression tests with python run_tests.py. Installation.
