Testing Strategy

Ideon uses Jest with ESM support and focused test suites.

Current Suites​

  • options.test.ts: T2I coercion/sanitization/defaults
  • articleSchema.test.ts: schema boundary validation
  • markdown.test.ts: markdown rendering contract
  • pipeline.runner.test.ts: stage orchestration behavior (multi-targets, generation dirs, resume semantics)
  • config.resolver.test.ts: precedence and idea resolution
  • previewHelpers.test.ts and previewServer.test.ts: recursive discovery, generation grouping, preview resilience, asset serving
  • previewServer.internals.test.ts and previewServer.branches.test.ts: preview branch/error-path and shell/API behavior
  • src/preview-app/App.test.tsx: React preview integration behavior (selection, tab switching, logs inspector)
  • src/preview-app/interactions.test.ts: interaction normalization and grouping utilities
  • prompts.framework.test.ts: framework/style/content-type prompt layering
  • write.command.test.ts: target parsing and CLI write option behavior

Run Tests​

npm test
npm run test:watch
npm run test:coverage

Quality Gates​

Recommended baseline before merge:

npm run lint
npm test
npm run build
npm run docs:build

Extending Coverage​

Priority additions:

  • More preview UI interaction coverage (theme, mobile drawer, and empty/error states)
  • Additional failure-path coverage for provider responses
  • Integration coverage for delete semantics in mixed generation directories
