|
|
|

|
|
See [deprecation notice for `karma`](https://github.com/karma-runner/karma#karma-is-deprecated-and-is-not-accepting-new-features-or-general-bug-fixes).

[Web Test Runner](https://modern-web.dev/docs/test-runner/overview/),
|
||
|
|
[`jasmine-browser-runner`](https://github.com/jasmine/jasmine-browser-runner),
|
||
|
|
and [`playwright-test`](https://github.com/hugomrdias/playwright-test) provide
|
||
|
|
browser-based unit testing solutions which can be used as a direct alternative.
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
The easiest way is to keep `karma-firefox-launcher` as a devDependency in your `package.json`.
|
||
|
|
|
||
|
|
You can simple do it by:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
npm install karma-firefox-launcher --save-dev
|
||
|
|
```
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
```js
|
||
|
|
// karma.conf.js
|
||
|
|
module.exports = function (config) {
|
||
|
|
config.set({
|
||
|
|
plugins: [require("karma-firefox-launcher")],
|
||
|
|
browsers: [
|
||
|
|
"Firefox",
|
||
|
|
"FirefoxDeveloper",
|
||
|
|
"FirefoxAurora",
|
||
|
|
"FirefoxNightly",
|
||
|
|
],
|
||
|
|
});
|
||
|
|
};
|
||
|
|
```
|
||
|
|
|
||
|
|
You can pass list of browsers as a CLI argument too:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
karma start --browsers Firefox,Chrome
|
||
|
|
```
|
||
|
|
|
||
|
|
To run Firefox in headless mode, append `Headless` to the version name, e.g. `FirefoxHeadless`, `FirefoxNightlyHeadless`.
|
||
|
|
|
||
|
|
### Environment variables
|
||
|
|
|
||
|
|
You can specify the location of the Firefox executable using the following
|
||
|
|
environment variables:
|
||
|
|
|
||
|
|
- `FIREFOX_BIN` (for browser `Firefox` or `FirefoxHeadless`)
|
||
|
|
- `FIREFOX_DEVELOPER_BIN` (for browser `FirefoxDeveloper` or
|
||
|
|
`FirefoxDeveloperHeadless`)
|
||
|
|
- `FIREFOX_AURORA_BIN` (for browser `FirefoxAurora` or `FirefoxAuroraHeadless`)
|
||
|
|
- `FIREFOX_NIGHTLY_BIN` (for browser `FirefoxNightly` or
|
||
|
|
`FirefoxNightlyHeadless`)
|
||
|
|
|
||
|
|
### Custom Firefox location
|
||
|
|
|
||
|
|
In addition to Environment variables you can specify location of the Firefox executable in a custom launcher:
|
||
|
|
|
||
|
|
```js
|
||
|
|
browsers: ['Firefox68', 'Firefox78'],
|
||
|
|
|
||
|
|
customLaunchers: {
|
||
|
|
Firefox68: {
|
||
|
|
base: 'Firefox',
|
||
|
|
name: 'Firefox68',
|
||
|
|
command: '<path to FF68>/firefox.exe'
|
||
|
|
},
|
||
|
|
Firefox78: {
|
||
|
|
base: 'Firefox',
|
||
|
|
name: 'Firefox78',
|
||
|
|
command: '<path to FF78>/firefox.exe'
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Custom Preferences
|
||
|
|
|
||
|
|
To configure preferences for the Firefox instance that is loaded, you can specify a custom launcher in your Karma
|
||
|
|
config with the preferences under the `prefs` key:
|
||
|
|
|
||
|
|
```js
|
||
|
|
browsers: ['FirefoxAutoAllowGUM'],
|
||
|
|
|
||
|
|
customLaunchers: {
|
||
|
|
FirefoxAutoAllowGUM: {
|
||
|
|
base: 'Firefox',
|
||
|
|
prefs: {
|
||
|
|
'media.navigator.permission.disabled': true
|
||
|
|
}
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Loading Firefox Extensions
|
||
|
|
|
||
|
|
If you have extensions that you want loaded into the browser on startup, you can specify the full path to each
|
||
|
|
extension in the `extensions` key:
|
||
|
|
|
||
|
|
```js
|
||
|
|
browsers: ['FirefoxWithMyExtension'],
|
||
|
|
|
||
|
|
customLaunchers: {
|
||
|
|
FirefoxWithMyExtension: {
|
||
|
|
base: 'Firefox',
|
||
|
|
extensions: [
|
||
|
|
path.resolve(__dirname, 'helpers/extensions/myCustomExt@suchandsuch.xpi'),
|
||
|
|
path.resolve(__dirname, 'helpers/extensions/myOtherExt@soandso.xpi')
|
||
|
|
]
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
**Please note**: the extension name must exactly match the 'id' of the extension. You can discover the 'id' of your
|
||
|
|
extension by extracting the .xpi (i.e. `unzip XXX.xpi`) and opening the install.RDF file with a text editor, then look
|
||
|
|
for the `em:id` tag under the `Description` tag. If your extension manifest looks something like this:
|
||
|
|
|
||
|
|
```xml
|
||
|
|
<?xml version="1.0" encoding="utf-8"?>
|
||
|
|
<RDF xmlns="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:em="http://www.mozilla.org/2004/em-rdf#">
|
||
|
|
<Description about="urn:mozilla:install-manifest">
|
||
|
|
<em:id>myCustomExt@suchandsuch</em:id>
|
||
|
|
<em:version>1.0</em:version>
|
||
|
|
<em:type>2</em:type>
|
||
|
|
<em:bootstrap>true</em:bootstrap>
|
||
|
|
<em:unpack>false</em:unpack>
|
||
|
|
|
||
|
|
[...]
|
||
|
|
</Description>
|
||
|
|
</RDF>
|
||
|
|
```
|
||
|
|
|
||
|
|
Then you should name your extension `myCustomExt@suchandsuch.xpi`.
