Overview
Automated test generation, execution, and evolution for your repositories.
Paragon Testing lets you generate, run, and evolve tests for your repositories. Import existing tests, generate new ones with Paragon, and let it automatically propose test updates when your code changes.
How It Works
- Add a repository — Connect a GitHub repository and configure test settings
- Import or generate tests — Import existing tests or generate new ones with Paragon
- Run tests — Execute manually, on schedule, or automatically on PR/push
- Evolve tests — Paragon proposes test updates when your code changes
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
- Agentic 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
