## Setup
|
|
|

- Execute `npm install` from the root folder
|
|
|
|
## Run
|
|
|
|
You can run the unit tests in two environments:
|
|
|
|
- Node.js: Execute `npm run test-unit` from the root folder
|
|
- Browser: Execute `npx servez -p 8080 --ssl` (or run any other local web sever) from the root folder and access `https://localhost:8080/test/unit/UnitTests.html` in a web browser.

## Notes
|
|
|
|
A small number of tests can only be run in a browser environment.
|
|
|
|
For browser tests, further changes to the library will not be reflected until the page is refreshed.
|
|
|
|
## Troubleshooting
|
|
|
|
When adding or updating tests, the most common cause of test failure is forgetting to change `QUnit.todo` to `QUnit.test` when the test is ready.
|
|
|
|
An error that indicates "no tests were found" means that an import statement could not be resolved. This is usually caused by a typo in the import path.
|
|
|
|
## Debugging
|
|
|
|
To debug a test, add `debugger;` to the test code. Then, run the test in a browser and open the developer tools. The test will stop at the `debugger` statement and you can inspect the code.
