Cross browser testing is essential for the survival and stability of any web app. But, What are the factors that need to considered while performing cross browser testing?

Have a look !

Understand the fundamental concept of cross browser testing

Before you start with cross-browser testing, it is very important to understand all the basic concepts of it. Be sure you are clear on all the concepts like

  • What is cross browser testing?
  • Its requirements and objectives. 
  • When you are required to do it.
  • Skills you are required to know to perform cross-browser testing.
  • The complete procedure to do it.

When you have all the above answers follow a systematized procedure to carry out cross-browser testing.

Delineate a checklist

Preparing a checklist can help you execute your tests in an organized way saving you on time and efforts.

They help in setting scope for your cross-browser testing. It can also help you to estimate the time required for the testing and can assure you that you don’t miss out on any browser or operating system.

Your checklist can include the below-given tabs –

  1. Operating Systems
  2. Devices
  3. Browsers and their versions
  4. Combinations of the above three
  5. Design and Animation Authentications to be checked
  6. Functional Authentications to be checked
  7. Content Authentications

Getting the Correct Combination

The main objective of Cross Browser Testing is to test the proper working of web applications on multiple browsers and operating systems.

With new versions of browsers and operating systems releasing almost every month, the possible combinations keep growing and thus increasing the efforts and time required for testing.

In such cases, the best strategy for you is to consider the most recent versions and the most popular versions.

As per to W3C, 97% of the internet users uses 4 major browsers i.e. Chrome, Firefox, IE and Safari.


The web world has now moved out from your desktops and laptops and has spread its wings to the mobile devices.

With a number of platforms available to access the websites, it becomes very important that your website design is responsive.

Your website should be easily accessible on desktops, tablets, and mobile for being available to a large section of people.

But with numerous devices available, it is difficult to test them on all the devices.

So a better strategy in such a scenario is to use tools to simulate the environment of the diverse device than testing them manually on every device.

Or another strategy could be to use Google Analytics or other similar tools and find out the most commonly used device and to carry out the testing in those specific devices.

Summarize the Test Scenarios

Seeing the vast possibilities of test scenarios, it is better to summarize them first.

Start with choosing the major browsers first and then covering other browsers.

Check if you need to test the complete application or checking a part of it will suffice.

Your strategy should be to prioritize testing. Try to check critical functionalities on major browsers and major platforms first and then proceed to the rest.

Use of Virtual Environments and Emulators

Checking various combinations of browsers is a tiring and time-consuming job.

While testing various combinations of browsers and platforms it is advisable to set up virtual machines with their own operating system and a different set of browsers.

Few browsers like chrome also offer you the freedom to access different extensions to help you emulate other browsers.

Emulator and Virtual machines are definitely time saving and efficient strategies for cross-browser testing.

Use of Automation Testing

In cross-browser testing, not only the change in your code requires retesting but changes in the browsers and operating system also requires you to retest your code.

In such scenario carrying out manual testing every time could be very hectic and time-consuming for you.

In cross-browser testing, we always suggest you carry out automation testing to save on time and for better efficiency.

Best Time for Cross-Browser Testing

It is always better to start testing in the early phase of development. Keep testing unit by unit.

And you should then repeat unit testing once the development phase is over.

Testing in the later phases can be very tiring and is prone to more faulty results.


In a world where technology is not driven by one common platform, it becomes very important for you to test that your product works fine for all available platforms.Internet users today have multiple choices of browsers and platforms.Always be sure that your application is compatible with all the browsers, devices and platforms and to their various combinations.
