karma-phantomjs-launcher
Launcher for PhantomJS.
Installation
The easiest way is to keep karma-phantomjs-launcher
as a devDependency in your package.json
, by running
$ npm install --save-dev karma-phantomjs-launcher
Configuration
// karma.conf.js
module.exports = function(config) {
config.set({
browsers: ['PhantomJS', 'PhantomJS_custom'],
// you can define custom flags
customLaunchers: {
'PhantomJS_custom': {
base: 'PhantomJS',
options: {
windowName: 'my-window',
settings: {
webSecurityEnabled: false
},
},
flags: ['--load-images=true'],
debug: true
}
},
phantomjsLauncher: {
// Have phantomjs exit if a ResourceError is encountered (useful if karma exits without killing phantom)
exitOnResourceError: true
}
})
}
The options
attribute allows you to initialize properties on the phantomjs page
object, so
options: {
windowName: 'my-window',
settings: {
webSecurityEnabled: false
},
}
is equivalent to:
var webPage = require('webpage')
var page = webPage.create()
page.windowName = 'my-window'
page.settings.webSecurityEnabled = false
You can pass list of browsers as a CLI argument too:
$ karma start --browsers PhantomJS_custom
If you set the debug
option to true
, you will be instructed to launch a web browser to bring up the debugger. Note that you will want to put debugger;
statements in your JavaScript to hit breakpoints. You should be able to put breakpoints in both your test code and your client code. Note that the debug
option automatically adds the --remote-debugger-port=9000
and --remote-debugger-autorun=yes
switches to PhantomJS.
