Cross-Browser Testing:

Testing the website or application in different browsers is known as Cross-Browser testing. Also, it ensures that your website or application's performance should be consistent without any dependencies and compromise in the Quality. This type of testing is applicable for both web and mobile applications.

It make reference to manual and automated testing of a website, also web-based/mobile-based applications over different browsers. The major focus of this type of testing is to make sure that the application or website looks and performs in a same way over different browsers and platforms. The application or website should be stable with the existing version of the browser.

Importance of Cross-Browser Testing:

Website or applications may look and perform differently on different browsers and you can't be sure that which browser your customers may use. Mostly, people visited the website but they may not be aware of browser compatibility issues and they'll leave the website thinking that it is not working.
So for this problem, you should follow the standards and build a professional looking website that works across different browsers with slight variations.

How Do We Perform Cross-Browser Testing:

When you have to perform Cross-Browser testing manually on your website or application then download the latest versions of the different browsers. But if in any case, you are unable to do it then there are many web-based tools that you can use.

Some of the tools are BrowserStack, Ghostlab, and CrossBrowserTesting, but these tools are not free. Also, there are some tools which are free and each will provide multiple testing features.
