Built-in tests

Testaro includes about 50 of its own tests, mostly to complement tests from other rule engines.Read 12 Oct 2026 · github.com

Execution modes

It can run a single job and quit, poll a directory for jobs, or poll a server for jobs.Read 12 Oct 2026 · github.com

How it works

A job identifies a web page and the rule engines to run; Testaro adds the results to the job to create a report.Read 12 Oct 2026 · github.com

Integration

Applications can use Testaro programmatically through its doJob function and monitor progress through emitted events.Read 12 Oct 2026 · github.com

Job workflow

A job typically identifies a page URL and asks Testaro to run multiple rule engines, adding their results to create a report.Read 12 Oct 2026 · github.com

License and distribution

The project is MIT-licensed and can be installed independently by cloning the repository or as an npm dependency.Read 12 Oct 2026 · github.com

Notable limit

Some target sites can prevent automated testing, and Testaro reports when a test act is prevented.Read 12 Oct 2026 · github.com

Notable limitation

The host must permit sandboxed browsers; otherwise Chromium launches can fail, and QualWeb's Chromium launch cannot use the documented non-sandbox workaround.Read 12 Oct 2026 · github.com
