BrowserStack<\/a> is a popular cloud testing platform because it provides instant access to all desktop and mobile browsers. And you don’t have to set up virtual machines and devices and browsers. Furthermore, the most effective part is you can run your tests in parallel in different environments. The widest usage of this platform is running selenium scripts on the cloud. But what about load testing a BrowserStack script.<\/p>\n

BrowserStack does not do load testing. However, you can take the scripts that you create for BrowserStack and use them for load testing with a simple modification. This post will walk through the steps with an example script.<\/p>\n

BrowserStack Script<\/h2>\n

Below is a simple automation code written in Node.js to perform a cloud test on BrowserStack.<\/p>\n

Here is a script for BrowserStack:<\/p>\n

var webdriver = require('selenium-webdriver');\nvar capabilities = {\n 'browserName' : 'Chrome',\n 'browser_version' : '62.0',\n 'browserstack.local':true,\n 'os' : 'Windows',\n 'os_version' : '10',\n 'resolution' : '1024x768',\n 'browserstack.user' : 'mahirkaplanc1',\n 'browserstack.key' : ''\n}\n\nvar driver = new webdriver.Builder().\n  usingServer('http:\/\/hub-cloud.browserstack.com\/wd\/hub').\n  withCapabilities(capabilities).\n  build();\n\ndriver.get('http:\/\/slot8.ss.etiya.com\/telaura\/faces\/telaura').then(function(){\n  driver.findElement(webdriver.By.name('uname')).sendKeys('username\\n').then(function(){\n    driver.findElement(webdriver.By.name('password')).sendKeys('password\\n').then(function(){\n      driver.findElement(webdriver.By.id('cb1')).click().then(function(){\n    \n      driver.quit();\n  });\n  });\n  });\n});\n<\/pre>\n
We will modify and simplify the script to run it on the Redline13 load testing platform.<\/p>\n
test.js<\/p>\n
var redline = require( 'redline13-webdriver' );  \/\/import redline13 library\nvar driver = redline.loadBrowser('chrome');  \/\/this might be chrome,firefox,phantomjs.\nvar By = redline.webdriver.By; \/\/ using By library for locator \nvar URL = \"http:\/\/slot8.ss.etiya.com\/telaura\/faces\/telaura\";\n\/\/Rest of the code is the same of Webdriver code\ndriver.get(URL);  \/\/navigate to url\ndriver.manage().window().maximize();\ndriver.findElement(By.name(\"uname\")).sendKeys(\"username\");  \/\/ enter username \ndriver.findElement(By.name(\"password\")).sendKeys(\"password\"); \/\/ enter password\ndriver.findElement(By.id(\"cb1\")).click();      \/\/ enter login button\ndriver.quit();<\/pre>\n
Both of these use a Javascript programming language. However we can use the \u201credline13-webdriver\u201d library to create a script with easier syntax and much clearer. And you won\u2019t have to handle Javascript promises.<\/p>\n
If you don\u2019t have Redline13 library, just run the following to set it up:<\/p>\n
npm install redline13-webdriver<\/strong><\/p><\/blockquote>\n
You have completed the installation. You are ready to run your script. You can check that your script works on your local machine with a command prompt:<\/p>\n
node test.js<\/strong><\/p><\/blockquote>\n
Running a Load Test<\/h2>\n
It’s time to upload the script on Redline13 to perform a load test.<\/p>\n
Steps are:<\/p>\n
