A large-scale artificial PHP codebase designed for benchmarking and profiling Infection mutation testing framework performance.

This repository provides a substantial codebase with comprehensive test coverage to evaluate Infection's performance under realistic conditions. The codebase is automatically generated to ensure consistency and scalability.

Generate code coverage reports for benchmarking:

make generate_coverage

This command:

• Executes the PHPUnit test suite with Xdebug coverage enabled
• Generates XML coverage reports in dist/coverage/xml/
• Generates JUnit test reports in dist/coverage/junit.xml
• Normalizes absolute paths in reports for reusability.

⚠️ Warning: due to the random order of tests, the coverage generation is not deterministic.

Regenerate all auto-generated source and test files:

make generate_code

⚠️ Warning: All files under src/AutoGenerated/ and tests/AutoGenerated/ are auto-generated. Do not modify them manually as changes will be overwritten.

Execute the test suite without coverage:

make phpunit

make help

To add new auto-generated code patterns, see the code-generator README.
