WebTest helps you test your WSGI-based web applications, which includes most actively developed Python web frameworks.
WebTest helps you test your WSGI-based web applications. This can be any application that has a WSGI interface, including an application written in a framework that supports WSGI (which includes most actively developed Python web frameworks – almost anything that even nominally supports WSGI should be testable).
With this you can test your web applications without starting an HTTP server, and without poking into the web framework shortcutting pieces of your application that need to be tested. The tests WebTest runs are entirely equivalent to how a WSGI HTTP server would call an application. By testing the full stack of your application, the WebTest testing model is sometimes called a functional test, integration test, or acceptance test (though the latter two are not particularly good descriptions). This is in contrast to a unit test which tests a particular piece of functionality in your application. While complex programming tasks are often is suited to unit tests, template logic and simple web programming is often best done with functional tests; and regardless of the presence of unit tests, no testing strategy is complete without high-level tests to ensure the entire programming system works together.
WebTest helps you create tests by providing a convenient interface to run WSGI applications and verify the output.
