buster-selenium

Build Status

An extension for buster.js to make it easy to write functional tests with either selenium-webdriver, wd, and webdriverio.

This extensions is only for tests run in node environment.

Install

Installation is done using npm:

$ npm install buster-selenium

Usage

Add buster-selenium extension and corresponding options, to the buster.js config file:

var config = module.exports;

config["Browser tests"] = {
    rootPath: "../",
    tests: ["test/**/*.js"],
    extensions: [require('buster-selenium')],
    'buster-selenium': {
        // required, can be either selenium-webdriver or wd
        driver: 'selenium-webdriver'
    }
}

Write the tests! Please check the documentation of the webdriver module you choose to use. Remember to quit the browser!

var buster = require('buster');

buster.testCase('goToGoogle', {
    'Load google.com': function(){
        var browser = this.webdriver.browser();

        return browser.get('http://www.google.com').then(function(){
            return browser.getTitle();
        }).then(function(title) {
            assert.equals(title, 'Google');
        }).then(function(){
            browser.quit();
        });
    }
});

Go check out Examples of how to setup buster.js config and tests.

Configuration

  • driver - (string or function) - required, choose selenium-webdriver, wd, or webdriverio strings or define a function that returns anything you want to use as the driver.
  • config - (object) - optional, configuration for the webdriver library. Each library is slightly different.
  • timeout - (number) - optional, defaults to 10000. Define how long a test runs before it timesout. Extend the time of your tests if the webdriver-driven browser takes a really long time to complete tasks.

Example

{
    driver: function(config){
        return new require('someOtherWebdriver')(config);
    },
    config: {
        exampleOption: true,
        exampleOption2: false
    }
}

selenium-webdriver config

  • server - (string) - url to the Selenium Server/Hub.
  • desiredCapabilities - (object) - define capabilities for the browser

Note: If phantomjs is not found in $PATH variable, it may be necessary to define the path in desiredCapabilities.

Example

{
    server: 'http://localhost:4444',
    desiredCapabilities: {
        browserName: 'phantomjs',
        'phantomjs.binary.path': './node_modules/.bin/phantomjs'
    }
}

wd config

  • server - (string or object) - url or parameters to the Selenium Server/Hub. Check wd browser-initialization docs for examples
  • desiredCapabilities - (object) - define capabilities for the browser

Note: Defining path to phantomjs is not necessary.

Example

{
    server: 'http://localhost:444',
    desiredCapabilities: {
        browserName: 'phantomjs'
    }
}

webdriverio config

Refer to webdriverio options docs for an explanation of the config options.

Consider setting logLevel property to "silent" when using xml reporter.

Example (taken from a webdriverio example)

{
    desiredCapabilities: {
        browserName: 'chrome',
        version: '27',
        platform: 'XP'
    },
    host: 'hub.browserstack.com',
    port: 80,
    user : process.env.BROWSERSTACK_USERNAME,
    key: process.env.BROWSERSTACK_ACCESS_KEY,
    logLevel: 'silent',
}

Usage

Every test will be extended with a webdriver object with access to two properties.

  • driver - (object) - The require'd webdriver node module. Ex. require('wd'); or require('selenium-webdriver');
  • browser - (function) - A wrapper function around the webdrivers browser builder/initializer. Returns a browser session object with the desiredCapbilities config.

Example

// assume we are using selenium-webdriver
buster.testCase('google', {
    setUp: function(){
        // Get a browser session
        this.browser = this.webdriver.browser();
    },

    tearDown: function(){
        // Quit the browser session, you should clean up every time
        this.browser.quit();
    },

    'go to google.com': function(){
        // Go to the google webpage and assert that its true
        // Buster tests can accept promises!
        return browser.get('http://www.google.com').then(function(){
            assert(true);
        })
    }
});

Notes: wd

wd provides three (at the time of this writing) types of remote/browser objects. A regular continuation style, a promise, and a promise chain. To access them, pass the browser function a string!

// Give me the promise remote/browser!
this.browser = this.webdriver.browser('promise');

// or

// Give me the promise chain remote/browser!
this.browser = this.webdriver.browser('promiseChain');

// or

// Give me the regular continuation style remote/browser!
this.browser = this.webdriver.browser();

Refer to wd docs for more info.
