Cross Browser Testing with LambdaTest

Tram Ho

This is the first article in the journey to learn about LambdaTest. Cross-browser testing is testing your web application on different browsers. Cross-browser testing is important in case you want most people to be able to use your application. LambdaTest works on cross-browser testing and provides you with a platform to test your application without installing a browser. Before we talk about LambdaTest, let’s see what cross-browser testing is.

1. What makes Cross-browser testing necessary?

To understand the need for cross-browser testing, let’s make a simple script. You are a developer of a website. You work from home. Because you have the time, you should upload your profile online. People have started replying to your profile. They care about you and want you to develop their website. Because you are working from home, you only have one system: your personal computer is equipped with two browsers: Google Chrome and Internet Explorer. After you’ve completed developing the website, you’ll see what it looks like in the browser. You provide your website to customers. But customers use more browsers than the ones you have. For example this is the statistics reuse the browser

Now the site is published and the site can be opened on mobile as well. If the website is not displayed best on mobile devices, the owner will lose a lot of traffic, which will ruin your reputation. You can buy 4-5 machines and install different operating systems on it. You should also have different browsers in there with different versions. This will cost you more money than you will earn. This is clearly not feasible. This is where cross-browser testing works. A process of testing web applications on different browsers and different operating systems including mobile platforms.

2. What is cross-browser testing?

Cross-browser testing refers to testing a web application on different web browsers and on different devices. Cross-browser testing helps developers understand how their applications will be viewed in different browsers.

  • Browsers play an important role in the development of a web application. The application may have some functionality that is not yet implemented in all major browsers or lower versions of the same browser. This will greatly affect the end user of the application and cause problems in some features of the application.
  • While showing it to users of your application, you can display warnings or popups for a good experience. But it is quite understandable that no one will actually install another browser or another version just to see your site. Not so long ago, there were only a handful of browsers available like Internet Explorer and Google Chrome, and most of them ran on desktop computers. That was different today. With the huge increase in the advancement of mobile technologies, the platform for viewing a web application has increased. These platforms include various web browsers and mobile platforms.
  • So, if you develop a web application, the main concern is how your application will be displayed in different browsers, because obviously, you don’t want to lose a large number of your end users.
  • Testing your web application against multiple browsers and platforms before publishing will ensure that every user, regardless of what platform he is on, will see your application as required.
  • Cloud-based cross-browser testing has simplified this complexity for you to an unimaginable level. One of your physical machines now works like 100 other machines without any costly investment.

Now, there are two methods of performing Cross-browser testing.

  • Manual testing
  • Tested through online tools

Manual testing

  • Manual testing is a method of testing applications manually in all browsers. For this way, you need to install the different browsers available on the internet into your desktop and mobile device. Remember that not everyone will have the same resolution and browser version as yours.
  • Also, you must remember that the different operating systems these browsers operate on both desktop and mobile devices. This is a very difficult and time-consuming task, from a cost management perspective, it is huge. Not only do you require different browsers on your computer, but you also need to have different machines to run different browser versions. Such an option is not effective and results in a high cost so it is not currently available.

Tested through online tools

  • The disadvantages of Manual testing web applications point us to how to use other online tools. We will use the tool is LambdaTest, they have installed all browsers and versions on their server, so that you can test your website on any browser and version you want. This way you save a lot of resources like your time, effort and money. – Using these tools will restrict you from installing browsers and their versions on different machines. You can only run a virtual machine with your intended specifications in the cloud and the website will run as usual on the physical machine.
  • Testing on such tools will also help you view and analyze various reports and many other things, which is almost impossible if you do it manually.

3. Introduction to LambdaTest

  • LambdaTest is an online tool used to perform interactive browser testing directly on your local or published web and web applications on 2000 real mobile and desktop browsers running on real operating system. Debug in real time on both desktop and mobile browsers with integrated debugging tools.
  • In general, LambdaTest provides you with a platform to relieve your stress about testing your web application on so many different browsers and their versions. Along with that, LambdaTest also offers tons of features included
  • Selenium automation test

  • Automatic screenshot of the test

  • Responsiveness test

  • Use Tunnel to test local pages

  • Regression testing

  • Test screen resolution

  • GeoLocation test

  • LambdaTest also has a unique and very important feature of integration with third party applications. With LambdaTest, you can test your web application and then post issues or bugs to another application like Jira, Slack, GitHub, etc.
  • LambdaTest has also introduced automation testing options in their tools recently. Automation test can be performed on Selenium grid. You can put up to 10 tests in the queue.
  • LambdaTest also allows you to take screenshots of the browsers you choose to test. You are allowed to take 25 screenshots at a time.
  • LambdaTest is used by many people to test and improve their web applications so that anyone who uses it will find it most friendly. Over time, LambdaTest is improving every day by providing integration for many other software along with the aforementioned features.
