Humbug is a mutation testing framework for PHP that measures the real effectiveness of test suites by injecting small defects and checking whether tests detect them. It is deprecated in favor of the Infection project.
Use cases
- measure the real effectiveness of my php test suite
- run mutation testing on a php codebase
- find gaps in unit tests beyond code coverage
- check if my tests catch injected bugs
- improve test quality with mutation analysis
When to choose
- you maintain a legacy PHP project already configured with Humbug
When to avoid
- you are starting a new PHP project - use Infection instead
- you need an actively maintained mutation testing tool
