## Tests

The tests are written using karma to simulate a browser environment.
The tests are written using [web-test-runner](https://modern-web.dev/docs/test-runner/overview/)

Probably in the section above we need to add a line for how to install the Playwright browser binaries, otherwise yarn test will not work.

We also need to specify which version of Yarn to use, because yarn playwright install worked for me in yarn v1 and v4 but not v3.

It is weird that it does not work with v3.

Yeah, I wonder if what I was seeing actually had more to do with my other comment (about putting @playwright/test in the top-level package.json)

to test in browser environment (provided by [playwright](https://playwright.dev/)).

If you have never installed playwright before or updated it, you need to install the browsers
by executing:

```bash
npx playwright install

```

To run the tests, run:

```bash
yarn build:test
yarn test # optionally test:chrome, test:firefox, or test:webkit
yarn test # optionally test:chromium, test:firefox, or test:webkit
```

You can run the tests manually to debug them by going inside one package (e.g. `packages/application`)
and then executing `yarn test:debug`. This should open your browser
in which you will be able to select the test file to execute.
The outcome of the tests are displayed in the web browser console and you
can use the web browser debug capability to debug the tests.

> [!NOTE]
> The test files are transpiled and bundled before execution. Therefore
> when debugging in the browser, you must use the file `tests/lib/bundle.test.js`.
> Then you will need to apply the fix to the Typescript test file and re-run
> the test command (to trigger the bundling) to check the test is fixed.
