The main usage is to use the qtbot fixture, responsible for handling qApp creation as needed and provides methods to simulate user interaction, like key presses and mouse clicks: pytest-xdist lets you scale up by increasing the test thread count and scale out by distributing test execution to remote machines. By default, the suggested default test runner is unittest. Test files which pytest will use for testing have to start with test_ or end with _test.py We will demonstrate the way of working by writing a test file test_fibonacci.py for … pytest makes use of assert available in Python for verification of results, it gives out meaningful information which can be used for verification & debugging. pytest.raises is commonly used to raise exceptions, below is an example where Factorial of a number is calculated. Using the same unnecessary_math.py module that I wrote in the doctest intro, this is some example test code to test the ‘multiply’ function. So, to utilize pytest, you need to make it the default test runner first. if it uses make test instead: script: make test. By default, Visual Studio identifies unittest and pytest tests as methods whose names start with test.
