Testing

The bundle's tests

tests/Unit checks the configuration and the services it gives, the mapping of the controller and the stylesheet, and both filters: plain text escaped, HTML trusted only as Markup, sanitized or escaped otherwise, documents read and rendered by the application's UJO services. tests/Functional boots a small application — FrameworkBundle with AssetMapper and an HTML sanitizer, TwigBundle, phil/ujo-bundle and this bundle —, renders a template with both filters, and finds the controller and the stylesheet through AssetMapper. tests/js checks the controller and the decisions it makes without the DOM.

From the monorepo root:

vendor/bin/phpunit packages/text-diff-bundle/tests
(cd packages/text-diff-bundle && node --import ./tests/js/register.mjs --test tests/js)

The bundle is held to 100 % covered mutation score by Infection, like the library.

Testing an application

The output of the filters is deterministic: a functional test asserts on the rendered HTML, or counts the ins and del of a page with a crawler. A test of the controller's behaviour runs in a browser — Panther or Playwright — and checks data-text-diff-mode, aria-pressed, the counter's text and the element marked text-diff-current.
