Automate Testing - TheIntern.io Selenium Functional Testing Example including Seting Up Environment

Selenium - TheIntern.md

Automate Testing using - TheIntern.io and Selenium locally

Note: This tutorial focus on Automate Functional Testing on Ubuntu.

Environment Setup:

• Install : JDK - Java .
• Download: Selenium server - a *.jar file from this Link.
• Now, we need something to test our environment. Git Clone: TheIntern-Tutorial project from here.
• Install necessary npm packages using following commands :

cd intern-tutorial npm install --save-dev intern

Configuring Intern

Sample intern.js

Path : intern-tutorial/tests/intern.js

// Learn more about configuring this file at <https://theintern.github.io/intern/#configuration>.
// These default settings work OK for most people. The options that *must* be changed below are the
// packages, suites, excludeInstrumentation, and (if you want functional tests) functionalSuites
define({
	// Default desired capabilities for all environments. Individual capabilities can be overridden by any of the
	// specified browser environments in the `environments` array below as well. See
	// <https://theintern.github.io/intern/#option-capabilities> for links to the different capabilities options for
	// different services.
	//

	// The port on which the instrumenting proxy will listen
    proxyPort: 8080,

    // A fully qualified URL to the Intern proxy
    proxyUrl: 'http://localhost:8080/',

	// Browsers to run integration testing against. Note that version numbers must be strings if used with Sauce
	// OnDemand. Options that will be permutated are browserName, version, platform, and platformVersion; any other
	// capabilities options specified for an environment will be copied as-is
	environments: [
		{ browserName: 'firefox', version: '37', platform: [ 'Linux'] },
	],

	// Maximum number of simultaneous integration tests that should be executed on the remote WebDriver service
	maxConcurrency: 2,

	// Name of the tunnel class to use for WebDriver tests.
	// See <https://theintern.github.io/intern/#option-tunnel> for built-in options
	tunnel: 'NullTunnel',

	// Configuration options for the module loader; any AMD configuration options supported by the AMD loader in use
	// can be used here.
	// If you want to use a different loader than the default loader, see
	// <https://theintern.github.io/intern/#option-useLoader> for instruction
	loaderOptions: {
		// Packages that should be registered with the loader in each testing environment
		packages: [ { name: 'myPackage', location: '.' } ]
	},

	// Non-functional test suite(s) to run in each browser
	suites: [ /* 'myPackage/tests/foo', 'myPackage/tests/bar' */ ],

	// Functional test suite(s) to execute against each browser once non-functional tests are completed
	functionalSuites: [ 'tests/functional/index' ],

	// A regular expression matching URLs to files that should not be included in code coverage analysis
	excludeInstrumentation: /^(?:tests|node_modules)\//
});

Create Test File

Path : intern-tutorial/tests/functional/index.js

Ad following code to index.js

define(function (require) {
    var registerSuite = require('intern!object');
    var assert = require('intern/chai!assert');

    registerSuite({
        name: 'index',

        'greeting form': function () {
            return this.remote
                .get(require.toUrl('index.html'))
                .setFindTimeout(5000)
                .findByCssSelector('body.loaded')
                .findById('nameField')
                    .click()
                    .type('Elaine')
                    .end()
                .findByCssSelector('#loginForm input[type=submit]')
                    .click()
                    .end()
                .findById('greeting')
                .getVisibleText()
                .then(function (text) {
                    assert.strictEqual(text, 'Hello, Elaine!',
                        'Greeting should be displayed when the form is submitted');
                });
        }
    });
});

Start Selenium

java -jar selenium-server-standalone-2.xx.x.jar

Start Test

node node_modules/.bin/intern-runner config=tests/intern leaveRemoteOpen

This will open up Firefox and your Test will execute.

Test using Chrome

Note: Update your Google Chrome, make sure Chrome is >43.0

If you want to run Tests on Chrome, we need Chrome Driver.

Download it from here. (Always use latest)

Installing - Chrome Driver in Ubuntu

Unzip & Copy the downloaded ChromeDriver file to this path usr/local/share

Make Selenium Run - Chrome Driver

java -Dwebdriver.chrome.driver=/usr/local/share/chromedriver  -jar selenium-server-standalone-2.xx.x.jar

Change your Intern.js file to run tests on Chrome

environments: [
	{ browserName: 'chrome', version: '39', platform: [ 'LINUX'] },
	// { browserName: 'firefox', version: '37', platform: [ 'Linux'] },
]

Start Test

node node_modules/.bin/intern-runner config=tests/intern leaveRemoteOpen

Useful:

Selenium WebDriver API

https://theintern.github.io/leadfoot/Element.html

To run chrome Driver

You may need to give execute permission to chrome driver
