What is cross browser testing?

Cross-browser testing is a process in which web developers test their website or app for compatibility on different browsers, it is a technique in which the developer tools are used to see what code errors happen under different browsers. The compatibility issues can arise in different browsers due to small and nuanced differences between browsers that the developer was unaware of if he did not do cross-browser testing beforehand.

Why do you need cross browser testing?

You need cross-browser testing to ensure that your customers get the same experience regardless of which platform they use, whether it is different browsers, operating systems, and devices. Cross-browser testing is freeware and will allow you to make sure your site renders well to the people that visit your sites, and also you can check or fix compatibility issues before they become a problem for all of them, with this, it will help you satisfy the expectations of users who switch devices and broadens your product’s market appeal.

What are the core features of cross browser testing?
Live Testing

Live testing means being able to test your cross browser testing sites on a browser while you're developing it directly in the background; when you find an error or want to change something, your changes are immediately shown to all of your viewers. This can be done by uploading files and having them open their browsers at the same time, as well as through editing HTML and CSS without leaving the browser window.

Automated Testing

Automated testing is a cross-browser software testing process that tests web pages by performing tasks in each of the major browsers. This automated cross-browser testing is done without human intervention by writing a set of step-by-step instructions that are then interpreted and implemented by an automated software application. The states (text, color, border size) and values on which to test are defined as input parameters to the program by the tester or programmer before running it and can be changed dynamically at any time without stopping or restarting it.

Debugging Tools

Debugging tools in cross-browser testing are those that can be used to detect any errors or discrepancies between how two browsers display a piece of content. It typically looks for things like mismatches between colors, text formatting, and layout to help you identify potential problems with your website's HTML. This is especially useful for sites that use cascading style sheets (CSS) because it allows you to disable CSS and see how the site will appear without styling information applied.

2000+ Desktop Browser Compatibility

The 2000+ Desktop Browser Compatibility tests if the website passes the 2000+ HTML and CSS test. It offers web developers the ability to create websites so they can look good and function on most operating systems.

Free Trial

A free cross-browser testing trial is offered by a company, often in the form of an online preview. Also, cross-browser testing is free which allows potential customers to test initial interest and compatibility with a product before purchasing it outright.

What are the types of cross browser testing?
Browser-Focused Automation

Browser-focused automation sends a headless browser to execute your test cases. You can view the differences between browsers using hardware, software, and manual intervention to validate each change. You can also simultaneously use 3 or 4 different computers to run your tests here and it has increased speed and a reduced risk that some browser/OS combinations are not being tested thoroughly.

Browsers with Real Browsers

Browsers with real browsers use virtual machines or remote machines to run your tests using non-headless versions of the respective browsers. This form of cross browser testing online is free and best suited for functional regression suites that use passive observation.

Self-Hosted Set Up

The self-hosted setup has its own web driver library, it has a list of known bug databases where each browser includes its own list of bugs.

Who needs the cross browser testing?
Web Designers

Web designers need online cross-browser testing to determine whether an issue is a bug or just one rendering way versus another by checking it against other browsers and even searching the internet for similar issues to find out what others have done about them.

Front-End Developer

Front-end developers need open source cross-browser testing tools since they will build out a website using a mixture of technologies to provide access to as many people as possible, and each person will open the website using different browsers or platforms.

Beta Testers

Beta testers need cross browser testing to identify the glitches of their website before release to avoid any frustrations or confusion to the customers when it goes live.

Marketing Designers

Marketing designers need website cross-browser testing to ensure that despite minor differences among web browsers, such visual differences are unlikely to create usability issues since users should have identical menu structures and button functions no matter which device they're using.

What are the steps in using a cross browser testing service?
Step 1:

Know how to do cross-browser testing and check its cross-browser testing abilities.

Step 2:

Evaluate and read cross browser testing interview questions or stream cross browser testing tutorials.

Step 3:

Check its range of supported browsers and devices.

Step 4:

Know who will be using the cross browser testing tools, and consider the learning curve of the tool as many cross-browser testing tools are free and would require weeks of setup and training.

Step 5:

Run parallel test execution.

Step 6:

Report your test and wait. If all fails, you can contact support.

When is cross browser testing done?

Cross-browser testing is done during development. The developers in continuous integration pipelines test new features to make sure they’re cross-browser compatible before pushing the changes to production, and also in pre-release to make sure that no browser compatibility issues crop up in the latest version of the website.

How do I select browsers for testing?

Select browsers for testing based on their popularity to maximize your reach in any target market; and based on analysis on which browser-OS combinations are most commonly used by your target audience and on what devices your website is generally viewed on. You can also use the cross browser testing offline which can also help you invest in development first to produce clean code and keep changes rare once online.

Am I able to test behind my company’s firewall?

Yes, you can use either our local tunnel or enterprise connection manager to connect behind your company's firewall and test your website or web application.

Which locators are best suited for stable cross browser testing?

The built-in locator generator attempts to create stable locators. However, it is difficult to generate quality locators if no information is available; with this case, use the custom IDs for the UI elements of your application.

Is there any scope for increasing the test coverage with cross browser testing?

Yes, depending on the cross-browser testing tool, it must come with features such as ease of creation of test cases, parallel execution of test cases, on-demand access to multiple testing environments, etc. Helps in an overall reduction of testing time. This allows testers to cover more sets of browser-OS versions ensuring that the application runs perfectly on the majority of end-user devices.

Whose websites need cross browser testing?

Every website needs cross-browser testing, every site should be tested on as many screen sizes as possible because there are a lot of different types of old desktops, laptops, tablets, and phones, also understanding how each device responds dictates what you might do with the website you're building on.

What would happen if I did not use cross browser testing on my website?

This means that if your site isn't tested across all browsers and devices you're leaving out close to 50% of potential users, not only those who prefer using mobile devices exclusively as opposed to other types of internet-enabled gadgets.

What is the significance of cross browser testing to marketers?

The significance of cross-browser testing to marketers is finding out what features are not compatible across the web browsers. The free cross-browser testing tools can help you in finding issues in the aesthetics, features, and usability.

What is the significance of cross browser testing to the backend developer?

Back end developers need to test their code for browser compatibility to make sure that the web front-end, the interface, runs as expected in different browsers.

What do you mean by testing bugs in cross browser testing?

Testing for bugs means reproducing a bug or issues that already exist from one browser to another. This is done by looking at the code, finding out what's happening, then replicating it on other browsers.
