Custom mutation testing for Raxol using simplified approach.

This task provides basic mutation testing capabilities when full mutation testing tools have compatibility issues.

Usage

mix raxol.mutation [options]

Options

• --target - Target module or file to mutate (default: all core modules)
• --mutations - Number of mutations to generate (default: 10)
• --operators - Mutation operators to use (default: arithmetic,boolean)
• --report - Generate detailed report (default: true)
• --timeout - Test timeout per mutation (default: 30s)

Examples

# Run basic mutation testing
mix raxol.mutation

# Test specific module with more mutations
mix raxol.mutation --target lib/raxol/core/state_manager.ex --mutations 20

# Quick check with limited operators
mix raxol.mutation --operators arithmetic --mutations 5
