We will build a simple yet robust web UI test solution using Python, pytest, and Selenium WebDriver. I suspect your usecase involves a lot of things happening to the fixture inside the test, but that again begs for more clear example (maybe just as plain assert's) and, probably, evaluating your tests - as it is more common to see just. Every time a fixture is requested in a test (def test_1(global_var)) the fixture function will be called and the result will be passed as the parameter value: what's happening here is that because each test requires the global variable, global_var is being executed each time and resetting the value of pytest. In this chapter of our tutorial, we will provide you with a deeper insight into the magic happening behind the scenes, when we are defining a class or creating an instance of a class. JUnit is, in turn, a Java version of Kent’s Smalltalk testing framework. The full scikit-learn tests can be run using ‘make’ in the root folder.
