In today’s online and mobile environment, testing for browser compatibility is very crucial and entails two different processes, although these days, they are frequently carried out simultaneously. It is necessary to evaluate web applications for compatibility across various browsers and operating system versions. The second component of testing involves website and mobile app testing across a wide range of devices and operating systems.

In this article, we will explore browser compatibility through advanced testing approaches. For that let’s first discuss what browser compatibility testing is, its types, why it is necessary, ways to perform this testing, when to start, and what to test in browser compatibility testing. 

What is browser compatibility testing?

The term browser compatibility is also referred to as cross-browser compatibility, which describes how well a website or web application works on various devices and in any given browser version. As a result, browser compatibility testing guarantees that an online application or website works as intended across various device, browser, and operating system combinations as required by your product’s market share and user base.

Browser compatibility testing is a vital aspect of regression testing for websites and web applications. It includes both functional and non-functional testing, including design and usability to make sure that all website features work properly in a variety of browsers, including Edge, Chrome, Safari, and others.

With the help of browser compatibility testing, developers can make sure their applications function as intended across all supported browsers, giving the users an identical experience across all devices. Testing for browser compatibility is always necessary to ensure a program functions properly across various browsers and devices.

Why is browser compatibility testing necessary?

On the way to the success of every web testing, is ensuring that it is accessible and functional for all users, regardless of browser. How the introduction of browser compatibility testing can help a wide range of applications.

• Avoid differences in design: The app or website needs to render the same in every browser. If not, users can come across several interfaces, which would leave them with an adverse impression and a terrible user experience.
• Create a positive brand impression: Internet users have varying browser preferences and demand consistent with excellent quality regardless of any browser. If the website or app operates well on all the major browsers, it will always enhance the brand’s image and encourage user loyalty.
• Minimization of potential losses: Errors and inconsistent work across the browsers could result in a loss of users and, consequently, a reduction in revenue.
• Increased competitiveness: In this highly competitive environment with hundreds or thousands of comparable websites and services, seamless cross-browser functionality can provide an added advantage.
• Increasing audience: Users select browsers based on their specific preferences and needs. Browser compatibility testing guarantees that the application is available to the potential users.

The above-mentioned points show that testing for browser compatibility is essential to guarantee that the application is functioning properly. It is a very calculated move to boost productivity and establish the brand’s position in the marketplace.

Types of Browser Compatibility Testing

A variety of tests are included in browser compatibility website testing, all of which are intended to pinpoint certain elements of how an online application operates and appears across various browsers and platforms. There are two major forms of browser compatibility testing-

Exploratory testing

Software testing that focuses on defect discovery and relies on the guidance of the individual tester to find flaws that are difficult to cover in the scope of other tests is known as exploratory testing, sometimes known as simultaneous learning, test design, and execution.

The process of enabling testers to access a product and identify flaws and bugs without the use of a script or test cases is known as exploratory testing. It also inspires testers to utilize their imaginations and imitate end users’ behaviors to emulate real-world usage.

The main purpose of exploratory testing is to find vulnerabilities that could compromise the proper functioning of the website and to analyze how the web application reacts to this erratic user activity. The main significance of exploratory testing is that it allows the developers to better understand how the consumers engage with their product and how it reacts to various activities.

UI testing

UI Testing is known by another name, GUI testing, or user interface testing, is essentially a method that is used to test the features of any product that a person will interact with. This typically entails evaluating the visual elements to ensure that they function and perform as intended to ensure that they are operating by specifications. User Interface testing makes sure that there are no bugs in the UI functions.

Websites contain web elements that are produced using CSS, JavaScript, and a variety of other computer languages. To verify the effectiveness of these components, UI testing runs with assertions and tests on them.

The main objective of UI testing is to guarantee that the website appears consistently and correctly across all supported platforms. The significance of UI or visual testing lies in its ability to identify flaws such as broken design, wrong element sizes, and the display of particular elements only on certain browsers.

Functional testing

Functional testing is a sort of testing that determines whether each program feature meets the software requirements or not. To determine if a function’s output meets the expectations of the end user, each function is compared to the related requirement. Sample inputs are supplied, the results are captured, and it is confirmed that the actual and anticipated outputs match to complete the testing process.

The primary objective of functional testing is to guarantee that all web application features are functioning properly by the defined requirements and specifications of the tests.

The significance of Functional testing is to ensure that users can complete the necessary actions on the website without encountering any problems or mistakes.

Each of these testing methods has a distinct purpose and application. Conducting all these three types of tests ensures that the web application is of high quality and is stable across all platforms, as well as that users are satisfied.

Ways to perform browser compatibility testing

To guarantee that all online applications run correctly and consistently across these various browsers and devices, browser compatibility testing is very essential. The two main testing techniques in this situation are manual and automated. Each one of these strategies has its benefits and drawbacks. Let’s discuss each of them in brief.

Manual browser compatibility testing

Manual browser compatibility testing entails a Quality Assurance engineer manually engaging with the web application and testing its performance across various browsers and various devices using browser compatibility test scenarios.

Automated browser compatibility testing

The development of software scripts, or browser compatibility test scripts, that automatically test the online application across various browsers and devices is referred to as automated browser compatibility testing.

When to start browser compatibility testing

When it’s time to start browser compatibility testing it is a critical component of web application development. The timing of the launch of this type of testing has an impact on error identification and rectification, as well as the overall user experience.

• As soon as possible: The first method is to begin browser compatibility immediately. This option is particularly pertinent to development approaches like Agile, which prioritize the timely release of a functional product to the market. Testing for browser compatibility begins even before a single page is prepared for testing. Compatibility testing helps in finding and fixing problems early in the development process, which is good from a financial standpoint.

• After the development is complete: Browser compatibility testing is a must in situations where a third party develops a website or web application, like in an outsourced project. This is known as user acceptance testing. Starting browser compatibility testing after the development of the full program is complete is an alternative strategy. 

This approach is consistent with iterative development techniques such as the Waterfall methodology, which is not commonly used in today’s IT environment. The website can be tested across several browsers once it has been developed. Although it may take longer and cost more money to resolve defects at this point, doing so still helps to address important issues before release.

• Post-Release: Starting with browser compatibility testing after the application is made available to end users it is the last option that is available. It is better to test the application even though this isn’t the best choice. Testing and bug fixes can be carried out as a part of application change requests once the program is released. Although it is costly and requires numerous application installations, this will enhance user satisfaction.

The topic of when to begin testing browser compatibility is the one that development teams, project managers, and analysts can address. One of the solutions may be selected by the development process and particular task requirements. Furthermore, knowing how to carry out browser compatibility testing is an intricate engineering procedure requiring specialized software and expert knowledge.

What to test during browser compatibility testing

Testing for browser compatibility is a very complex procedure that necessitates a thorough examination of many different facets of online applications. To guarantee peak performance and that the application functions properly across all web browsers, it is very essential to take technical features and details into account during this entire process. Here are some of the key factors that need to be considered:

• Basic functions: Tests the efficiency of basic functions such as links, buttons, dialog boxes, and menus. Technical analysis includes ensuring that JavaScript events are properly handled in all browsers and that AJAX queries do not crash.
• Graphical User Interface (GUI): Technical evaluation of the application’s look across various browsers. It is very critical to ensure that the CSS styles are shown appropriately and that the element location on the page seems to be correct.
• Interaction with the user: Technical confirmation of how the application responds to the user input. Ensuring a prompt and efficient handling of keyboard and mouse events is very crucial. An investigation of code optimization is very necessary to provide a prompt response.
