Explore pytest, a rapid and simple testing framework for Python, in this EuroPython 2013 conference talk by Helger Krekel. Dive into developer-oriented automated tests, integration techniques, and fundamental py.test features. Learn about automatic test discovery, writing boilerplate-free Python test code, and utilizing test classes with pytest. Master assert introspection, exception assertion, and dependency injection. Discover the power of fixtures, including simple and parameterized examples, scoping, and modularity. Compare pytest with unittest, explore plugins like pytest-coverage, and get a glimpse of upcoming Pytest-2.4 features. Gain insights on test design and thoughtful implementation to enhance your Python testing practices.
