Adapters
The YAML is the contract. Adapters drive a browser — or skip it for HTTP.
| engine | Package | When |
|---|---|---|
playwright | @natl/adapter-playwright | Default |
selenium | @natl/adapter-selenium | WebDriver / Grid |
cypress | @natl/adapter-cypress | Cypress teams (MVP) |
http | built into @natl/core | API-only |
natl run suite.yaml --engine seleniumUI + HTTP → with: http in the guide.
