# Linktree CI Integration ## Overview Configure CI pipelines that validate Linktree link-in-bio API integrations using a two-tier testing approach. Unit tests mock the Linktree REST API to verify profile retrieval, link CRUD operations, and click analytics aggregation without needing an API key. Integration tests authenticate with a real Bearer token on main-branch merges to confirm link ordering, analytics endpoints, and rate limit handling against the live Linktree API. This ensures every PR gets instant feedback while production-critical flows are verified before deploy. ## GitHub Actions Workflow ```yaml # .github/workflows/linktree-tests.yml name: Linktree API Tests on: [push, pull_request] jobs: unit-tests: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - uses: actions/setup-node@v4 with: { node-version: '20' } - run: npm ci - run: npm run lint && npm run typecheck - run: npm test -- --testPathPattern=unit # No Bearer token needed integration-tests: runs-on: ubuntu-latest if: github.ref == 'refs/heads/main' needs: unit-tests steps: - uses: actions/checkout@v4 - uses: actions/setup-node@v4 with: { node-version: '20' } - run: npm ci - run: npm test -- --testPathPattern=integration env: LINKTREE_API_KEY: ${{ secrets.LINKTREE_API_KEY }} ``` ## Mock-Based Unit Tests ```typescript // tests/unit/link-service.test.ts import { describe, it, expe...
