​
Test Types

Paragon supports two modes of testing:

​
Code Tests (Unit & Integration)

Tests that live in your repository and run via your test framework.
  • Unit Tests: Test individual functions or components in isolation
  • Integration Tests: Test multiple parts working together (APIs, databases)
  • Frameworks: vitest, jest, mocha, pytest, go test, cargo test, and more
Code tests can run automatically on PRs and pushes.

​
E2E Tests (Step-Based)

Browser-based tests that run against a deployed URL.
  • Step-Based Builder: Visual interface to create test flows
  • AI Actions: Natural language steps like “fill in the login form”
  • Multi-Platform: Chrome, Firefox, Safari, Mobile
E2E tests run against your production or staging URL.

​
Performance Tests

Measure page load speed and Core Web Vitals.
  • Metrics: LCP, FCP, CLS, TTFB
  • Budgets: Set thresholds and get alerts when exceeded
  • Conditions: Test under various network and CPU throttling
