• Running Selenium Scripts On LambdaTest Cloud | Automated Cross Browser Testing

    In this post, we see how to run Selenium Scripts on LambdaTest Cloud Platform. Before that let’s learn why do we execute Selenium WebDriver tests on LambdaTest. In this post, we will learn the following.

    Many times, we face a situation where we have to run selenium scripts with multiple version of browsers. There are always limitations to run on local machines. We cannot install thousands of browsers in our local machine to perform automated cross-browser testing. Remote execution in the cloud is the solution to overcome this limitation. LambdaTest Selenium Automation Grid is a cloud-based, scalable Selenium testing platform which enables users to run their automation scripts on more than 2000 browsers and operating system. In the earlier post (LambdaTest Review), we didn’t mention how to run Java Selenium automated test cases on LambdaTest cloud. Here in this article, we will be looking how to configure and run Java-based automation test scripts on LambdaTest Selenium cloud platform.

    Running Selenium Scripts on LambdaTest Cloud Platform

    In this post, we would be exploring the following:

    What is LambdaTest

    LambdaTest is a Cross-Browser Testing Cloud, allows developers and testers to perform Cross Browser Testing on 2000+ Real Browsers and Operating System Online in varying screen resolutions. LambdaTest allows us to test on latest mobile and desktop browsers on the cloud.

    What is Cross Browser Testing

    Cross Browser Testing is a type of non-functional test which helps us ensure that our website or web application works as expected in various web browsers. We could do Cross Browser Testing on different browsers both manual and automated way. To do Cross Browser Testing manually, we (Software Testers) create tests for each browser and execute it manually on each browser. To do it in an automated way, we could create Selenium tests with multiple conditional statements that execute test cases based on a specified browser type. While testing a website, we need to ensure that our website is appearing same across all the browsers. To do this we need to have all the browsers. Fortunately, there are some tools (e.g., CrossBrowserTesting, LambdaTest) to perform cross-browser testing without testing individually in a manual way.

    Prerequisites to perform Cross Browser Testing Using Selenium

    1. LambdaTest Account – Here is a signup link
    2. LambdaTest Username and Access Key
    3. Java Development Kit (JDK) 1.6 or higher – Java Installation Link
    4. Selenium Jars
    5. TestNG Jars

    Run Selenium Tests on LambdaTest Cloud Platform

    Step 1: Understanding LambdaTest’s Selenium Grid capabilities is very important in using LambdaTest Cloud platform. LambdaTest’s Selenium Grid uses remote webdriver instead of normal Selenium client browser driver. You have to invoke LambdaTest Selenium remote Webdriver. You have to specify details such as browser, browser version, OS and resolution you wish to run your test on, along with LambdaTest specific capabilities.

    Step 2: Create a maven project – check this post for the same

    Step 3: Copy the below code and Run Selenium Test on LambdaTest. The below code tests a simple to-do application.

    Given clear explanation in the comments section within the program itself. Please go through it to understand the flow.

    Step 4: You have to generate Access token. Make a note of your User name and Access token and modify it in the above code.

    Run Selenium Tests on Multiple Browsers in Parallel on LambdaTest

    If you have more than one concurrent session, you can run your test cases on more than one machine at a time. This way you can save your test execution time a lot.

    Copy the below code and Run Selenium Test on multiple browsers in parallel on LambdaTest

    TestNG suite file:

    You can run your test suite on multiple browsers with simple annotations and parameters of TestNG, without changing the browsers parameters in the script every time.

    Cross browser testing comes as part of our job that too running Selenium Scripts in parallel makes our life easy in terms of saving time.
