WebdriverJs - Sample programme | Mocha | chai | Javascript

Here is the selenium web automaton sample code , using java script bindings.


Software Setup:
1.Install Node.js & npm
 Node.js from https://nodejs.org/en/download/ ( latest version and please install it )
- Node installs npm software by deault

verification: open command window and type
> node -v
7.2.1
>npm -v
3.10.10

2. Installing selenium :
Create a folder called "webdriver-js" any where and open a command window from the newly cerated folder "webdriver-js" and install selenium

>npm install --save--dev selenium-webdriver


3. install testing framework chai and mocha ( globally )
>npm install chai mocha -g


4. Download chromedriver.exe 
download and place the chromedriver.exe file here ( webdriver-js folder )
https://sites.google.com/a/chromium.org/chromedriver/downloads

5. Sample Script ( save as 'test-with-assert.js' in the same folder)

6.Run
>mocha test-with-assert.js

That's all .




with different way assertions : expect

------------------------

var chai = require('chai');
var expect = require('chai').expect;

// URL
var url = 'http://www.google.com';

        driver.get(url);
        this.timeout(50000);

            expect(title).to.equal('selenium - Google Search');
            done();
            console.log("Selenium Webdriver Chrome Shutdown");
        })
    });
