Learn how to implement mutation testing in Python using Cosmic Ray in this comprehensive conference talk from NDC TechTown. Explore the complete process from installation to execution and results analysis of Cosmic Ray mutation testing framework. Master the configuration and execution of mutation tests on Python codebases through hands-on demonstrations using a provided project. Discover how to evaluate test suite effectiveness by introducing controlled code mutations and analyzing how tests respond to these changes. Gain practical experience with advanced topics including creating custom mutation operators and integrating Cosmic Ray into continuous integration pipelines. Walk through real-world examples that demonstrate how to strengthen test suites by identifying untested code paths and improving test coverage through mutation testing techniques.
