# Parallel execution (default behavior in Bun)
# Bun automatically runs tests in parallel

# Timeout for individual tests (1.5 seconds)
timeout = 1500

# Coverage is NOT enabled by default - only the full test suite (bun run test)
# passes --coverage explicitly. This prevents ad-hoc test runs (bun test:unit,
# bun test test/some-file) from failing with exit code 1 due to coverage
# thresholds when all tests actually pass.

# Coverage thresholds - enforced only when --coverage flag is passed
# Full 100% coverage required for both lines and functions
coverageThreshold = { lines = 1.0, functions = 1.0 }

# Files excluded from coverage:
# - ensure-deps.js: defensive code that can't be meaningfully tested
# - validated-config.js: module-load-time validation that can only fail if config files are misconfigured
# - customise-cms/*: CLI scripts with hard-to-test file system operations
# - cli-io.js: I/O functions that read process.argv and call process.exit
# - pdf.js, image.js, image-crop.js, image-external.js: error handling for external library edge cases
# - console.js: console output utilities
# - test-runner-utils.js, test-utils.js: test infrastructure
# - recurring-events.js: date edge cases
# - cart-utils.js, quote-price-utils.js: browser-specific edge cases
# - array-utils.js: some utility functions only used in specific contexts
# - on-ready.js: document.readyState branch requires complex mocking
# - search.js: dynamic import("/pagefind/pagefind.js") only resolves against built site
# - screenshot.js, screenshots.js, lighthouse.js, browser-utils.js: Playwright/Chrome browser automation
# - configure-filters.js: Eleventy registration wiring (functions it calls are fully tested)
