Methods and Scenarios of Cross Browser Testing

Cross Browser Testing is a major testing type that is to be performed for web applications. This is because web applications developed by the development team can be accessed by the user from any browser, browser version, device, and OS platform, hence it becomes essential to test the compatibility of applications among different browsers, devices, and OS.

Cross-browser testing helps to prevent and ensure that the application works correctly in other web browsers and platforms also so that the users of other web browsers and platforms can feel the easy and defect-free flow of the application, and make the application to win the faith of other markets users.

Marketers, and Web Designers perform the cross-browser testing and can use them to test the landing of web pages.

The QA team is more responsible for performing cross-browser testing activities, they execute the same scenarios, and test cases with web applications across different browsers to ensure the compatibility of web applications, in case of any discrepancies QA team can raise the defect, and the development team can fix it.

When cross-browser testing can be performed ?

The cross-browser testing can be performed in the Development stage where new versions get integrated and tested with different scenarios in various web browsers and platform combinations.

Or it can be performed in the Staging/Pre-release environment of the application.

The Pre-Requisite of cross-browser testing is as follows :-

1). Choose critical scenarios that are to be tested in cross-browser testing, it could be UI, Security, Storage, Network, etc.

2). Choose the Test Environment, it is one of the major tasks in cross-browser testing in which the combination of web browsers, devices, and platforms is to be selected so that the maximum possibility of testing could be covered across different browsers.

3). Prioritize the browser according to the usage and popularity among users.

Some critical scenarios of cross-browser testing are:-

The scenarios based on Devices

1). To validate that websites or apps are compatible with tablets.

2). To validate that websites are compatible with mobile devices.

3). To validate the page layout of the application in different screen resolutions.

4). To validate the application compatibility with high configuration of hardware.

5). To validate the application compatibility with low configuration of hardware.

The scenarios based on Browsers

1). To validate that websites are accessible through the browser.

2). To validate that buttons of web applications can be displayed in the browser.

3). To validate that each element is clickable on the web page.

4). To validate that the web page takes too long to load in the browser.

5). To validate that all security fundamentals are followed in the scenarios.

The scenarios based on the Network

1). To validate that the website can be loaded successfully in complete network strength.

2). To verify that websites can be worked on slow networks.

3). To validate the rendering behavior of web pages in a slow network.

4). To validate that the major functionality of the application can be accessed in a slow network.

5). To validate that download and upload links functionality in the slow network connection.

The scenarios based on Security

1). To validate the criteria for password is followed under each browser, and OS combination.

2). To validate that guidelines for passwords are displayed in different browsers and platform combinations.

3). To validate that any error message doesn’t contain any critical application information.

4). To validate that cookies and cache storage don’t contain any password-related information.

5). To validate that the user can’t be navigated to the home page again without login, after successfully logging out from the application.

The major purpose of cross-browser testing is to ensure the compatibility of web applications in different browsers and platforms so that their users can experience defect-free applications and use them diligently.
