# Mutation Testing Configuration for CDK
# Phase 1: Focus on cashu crate only

# Start with cashu crate only - exclude other crates initially
exclude_globs = [
    "crates/cdk-*/**",  # Exclude other crates initially
    "**/tests/**",      # Don't mutate test code
    "**/benches/**",    # Don't mutate benchmarks
]

# Reasonable timeout to catch hangs (5 minutes minimum)
minimum_test_timeout = 300

# Skip specific mutations that cause infinite loops
# These mutations create scenarios where loops never terminate or recursive functions never return.
# Format: "file.rs:line.*pattern"
