> Launcher for Internet Explorer.
## Installation
The easiest way is to keep `karma-ie-launcher` as a devDependency, by running
```bash
npm install karma-ie-launcher --save-dev
```
## Configuration
```js
// karma.conf.js
module.exports = function(config) {
config.set({
browsers: ['IE']
});
};
```
You can pass list of browsers as a CLI argument too:
```bash
karma start --browsers IE
```
You can run IE in emulation mode by setting the 'x-ua-compatible' option:
```js
customLaunchers: {
IE9: {
base: 'IE',
'x-ua-compatible': 'IE=EmulateIE9'
},
IE8: {
base: 'IE',
'x-ua-compatible': 'IE=EmulateIE8'
}
}
```
See [Specifying legacy document modes] on MSDN.
### Running IE in "No add-ons mode"
Please note that since **v0.2.0** default behaviour of launching Internet Explorer has changed.
Now it runs using system-wide configuration (uses same settings as if you would run it manually) but prior to **v0.2.0** it was spawned with `-extoff` flag set explicitly, so all extensions were disabled.
If you expect the same behaviour as it was before **v0.2.0**, Karma configuration should be slightly changed:
- create new `customLauncher` configuration (`IE_no_addons` is used in an example below) with custom flags (in our case it is `-extoff` only)
- browser `IE` in `browsers` field should be replaced with your new custom launcher name
```js
browsers: ['IE_no_addons'],
customLaunchers: {
IE_no_addons: {
base: 'IE',
flags: ['-extoff']
}
}
```
