The URLs of the form `help://man/<section>/<page>` link to another help page inside the help application. All previous relative page links are replaced by this new form. This doesn't change any behavior but it looks much nicer :^) Note that man doesn't handle these new links, but the previous relative links didn't work either.

## Name
|
|
|
|
test-js - run the LibJS test suite
|
|
|
|
## Synopsis
|
|
|
|
```**sh
|
|
$ test-js [options...] [path]
|
|
```
|
|
|
|
## Description
|
|
|
|
`test-js` runs the LibJS test suite located in `/home/anon/js-tests`. These
|
|
tests are using a custom JavaScript testing framework inspired by
|
|
[Jest](https://jestjs.io) (see [`test-common.js`](/home/anon/js-tests/test-common.js)).
|
|
|
|
It also supports the [test262 parser tests](https://github.com/tc39/test262-parser-tests).
|
|
|
|
The test root directory is assumed to be `/home/anon/js-tests`, or `$SERENITY_SOURCE_DIR/Userland/Libraries/LibJS/Tests`
|
|
when using the Lagom build. Optionally you can pass a custom path to `test-js` to override these defaults.
|
|
|
|
You can disable output from `dbgln()` calls by setting the `DISABLE_DBG_OUTPUT` environment variable.
|
|
|
|
## Options
|
|
|
|
* `-t`, `--show-time`: Show duration of each test
|
|
* `-g`, `--collect-often`: Collect garbage after every allocation
|
|
* `--test262-parser-tests`: Run test262 parser tests
|
|
|
|
## Examples
|
|
|
|
A very simple test looks like this:
|
|
|
|
```js
|
|
describe("Examples from Gary Bernhardt's 'Wat' talk", () => {
|
|
test("Na na na na na na na na na na na na na na na na Batman!", () => {
|
|
expect(Array(16).join("wat" - 1) + " Batman!").toBe(
|
|
"NaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaN Batman!"
|
|
);
|
|
});
|
|
});
|
|
```
