FAQPage Schema

What is mutation testing and how does it improve code quality?▼

Mutation testing modifies code to verify test suite effectiveness, identifying untested logic. This ensures thorough quality assurance by revealing gaps that standard coverage metrics miss.

How do I configure a mutation testing campaign for my codebase?▼

Run the `mewt init` command to start a mutation testing campaign. You can then adjust the testing scope and tune timeouts to balance thoroughness with execution time for your specific codebase.

Do I need mewt or muton installed to run mutation testing campaigns?▼

Yes, you must have mewt or muton installed and configured in your environment. These tools are required dependencies for setting up and optimizing the mutation testing campaigns.

What is the best way to optimize mutation testing for long-running campaigns?▼

To optimize long-running mutation testing campaigns, tune the execution timeouts and adjust the testing scope. Applying these optimization strategies balances thoroughness with overall execution time.

When should I not use mutation testing in my workflow?▼

Avoid mutation testing on codebases lacking initial test coverage or when execution time is strictly limited. It requires thorough testing foundations and can be resource-intensive for large scopes.
