grunt-mocha-selenium
Run functional Mocha tests with wd with Selenium, Phantomjs and Appium.
Getting Started
This plugin requires Grunt.
If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
npm install grunt-mocha-selenium --save-dev
Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
grunt.loadNpmTasks('grunt-mocha-selenium');
The "mochaSelenium" task
Selenium tests are run by a standalone selenium driver that will be downloaded the first time the task is run. Chrome support is provided by the Chrome Driver plugin for Selenium and is provided on demand.
The task fires up a selenium instance for the browser of your choice (Firefox, Chrome or Phantomjs) and initializes an instance of wd, passing it to the mocha test runner's context.
Take a look in the test
directory for examples of what mocha tests
with wd look like.
Overview
In your project's Gruntfile, add a section named mochaSelenium
to the
data object passed into grunt.initConfig()
.
grunt.initConfig({
mochaSelenium: {
options: {
// Mocha options
reporter: 'spec',
timeout: 30e3,
// Toggles wd's promises API, default:false
usePromises: false
},
firefox: {
src: ['test/*.js']
// firefox is the default browser, so no browserName option required
},
chrome: {
src: ['test/*.js'],
options: {
// Chrome browser must be installed from Chromedriver support
browserName: 'chrome'
}
},
phantomjs: {
src: ['test/*.js'],
options: {
// phantomjs must be in the $PATH when invoked
browserName: 'phantomjs'
}
}
}
})
Options
The usual Mocha options are passed through this task to a new Mocha instance.
The following options can be supplied to the task:
options.usePromises
Type: Boolean
Default value: false
If enabled, this will use the promise-enabled wd browser API instead of the normal synchronous API.
options.host and options.port
If these are specified then a server will not be started but these settings will be used to connect to an existing server.
"options.username" and "options.accesskey" can be specified if you want to use Sauce Labs' on demand service.
options.wdCustomizer
If you'd like to add custom wd methods,
you can specify a wdCustomizer
path to a module that patches the wd module
before the wd remote is created.
Example:
grunt.initConfig({
mochaSelenium: {
options: {
reporter: 'spec',
timeout: 30e3,
useChaining: true
},
phantomjs: {
src: ['test/*.js'],
options: {
browserName: 'phantomjs',
wdCustomizer: 'test/wd_customizer'
}
}
}
})
test/wd_customizer.js
:
function wdCustomizer(wd) {
wd.addPromiseChainMethod(
'waitForSomethingCustom',
function(pageId) {
return this.waitForElementByCssSelector('#somethingCustom');
}
);
return wd;
}
module.exports = wdCustomizer;
Usage Examples
See this project's Gruntfile.js
for examples.
In this example, we'll run functional mocha tests for all files in the
test
directory using the wd promises API and the nyan-cat reporter.
grunt.initConfig({
mochaSelenium: {
options: {
reporter: 'nyan',
usePromises: true,
useChrome: true
},
all: ['test/*.js' ]
},
})
Contributing
In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
