Posted By : Sumita Goswami | 11-Jan-2021

What is Cross Browser Testing?


Cross-browser testing is Non-functional testing that involves compiling and evaluating the performance of your web page in contrasting gateway settings. It advises assuring that your web page distributes the best user practice, autonomous of the gateway used to approach it. It checks whether our gateway works as pretended when penetrating over different browsers:


  • Contrasting Browser-OS consolidations i.e., on prominent gateways like Firefox, Chrome, Edge, Safari—on any of the popular operating systems like Windows, macOS, iOS, and Android.
  • Contrasting devices- i.e., users can aspect and collaborate with your web page on prominent machines—smartphones, tablets, desktops, and laptops, etc.
  • Dependable Tools- i.e., the web page is adaptable with dependable automation like screen readers for individuals who are differently-abled.

Why Cross Browser Testing is necessary?


By operating cross-browser testing, we can assure that the web page operates as expected crosswise all the gateways. A web page constitutes current web automation and languages such as HTML, CSS, Python, SQL, PHP, and JavaScript. All these web techs associate to give a finalize peer and operate the website. When these web pages run on contrasting web gateways, shoot the web page code and demonstrate it to the users. But each gateway connects with the web pages particularly and illustrates the web peripheral occupying on their compromise to serve the web page properly. So it drops to web developers to brief gateways characteristics. The cross-browser testing benefit that by identifying gateway-definitive affinity issues so we can debug them expeditiously. It benefits to assure that we are not estranged a compelling part of our spot congregation–commonly because our web page does not work on their gateway-OS.


How to select Brower for testing?


  • Based on acceptance: Choose the 10-20 max approved or frequently used gateways. select the top three platforms—like Android and iOS. This is to diminish our arrival in any spot market. 

                 The intent is to look out-

                1. Which gateway-OS consolidation is most frequently used by our spot congregation

                2. What machines our web page is commonly explored on.

When to do Cross Browser Testing?


  • Create a guideline- Before we start cross-browser testing, execute all the designs and performance tests on the essential gateway-commonly Chrome. This will provide an idea of how the web page was basically designed to review and operate.
  • Create a testing plan- and pick the gateways to test on practice the test specification document to synopsis precisely what you’ll test. Then, as defined in the portion over, choose gateway -OS consolidation to test established on acceptance and website traffic study.
  • Execution- Automated vs Manual: Manual testing requires human testers to conclusively perform out test cases and test scenarios. Automated testing ‘automates’ human cooperation with the help of their code. An individual test script, executed by expert QAs using automation tools like Selenium, can shoot a test scenario on numerous gateways, as many times require. With particular bug-reporting, bugs are effortless to find and resolve. Manual testing has an area for human identified errors. Build upon the web page and scenarios that require to be tested, it can take anyplace bounded by a few hours to distinct weeks to outright. The left the tests can be automated for the immediate, responsive shoot and nearby-prompt assessment.

By now we all are aware that chrome is the best browser for testing but that does not mean we should ignore other browsers like Mozilla Firefox, safari. Testing the application on different browsers can be complicated. Hence, proper planning for testing is required. In such a scenario, we should divide the browsers based on their application and geography.
