Master The Art Of Cross Browser Testing

“The application runs fine on google chrome, but it is not working on Mozilla Firefox”

 

Sounds familiar, right?

 

Software testers like me working in a software testing company come across ‘incidents’ which will occur on one browser but not on another browser. While testing an application for cross-browser compatibility, the following are the key browsers to watch out for.

 

Ways to perform cross-browser testing:

  1. Cross browser testing can be performed manually.
  2. Testers may use cross-browser testing tools such as Spoon Browser Sandbox, browser shots, and browser.
  3. Cross browser testing websites such as Smartbearand Browserstack.

 

Some more useful tools are:

  1. Rapise
  2. Saucelabs

 

But first, let us understand why cross-browser conflicts occur?

  1. The JavaScript implementation can be different
  2. There can be differences in CSS and HTML validation
  3. Some browsers such as versions of Internet Explorerprior to V9 do not support HTML5
  4. Page alignment errors
  5. Browser incompatibility with OS
  6. Some browsers have non-identical levels of support for technology to others.

 

Why Do We Perform Cross-Browser Testing?

  1. Validate the appearance of the web page is same on all browsers.
  2. Validate that functionality is working as expected.

 

How Is Cross-Browser Test Executed?

Experienced testers from QA testing companies suggest that it is ideal to perform cross-browser testing by doing 100% testing on one browser per platform. And for the other browser, test for the most commonly used functionalities.

 

When To Perform Cross-Browser Testing?

Unlike user acceptance testing, early testing would reap the best benefits in this case. Therefore, start as soon as you get the page designs.

 

Difference Between Cross-Browser and Cross-Platform Testing

Often nivice testers assume that cross-browser testing and cross-platform testing are the same. But this is not the case. In cross-platform testing, you will see yourself testing an application on various platforms such as Windows, Linux, Mac etc.

With cross-browser testing, you will be running your application on various browsers like Chrome, Safari, Firefox, etc. There may be scenarios when the two have to integrate together as some of the browsers with older versions might be compatible only with the limited versions of the platforms.
