Cross-Browser Testing Tools for Web Apps: Ensuring Top-Level Security and Reputation

Laymen will keep doubting the need for cross-browser testing tools. They believe that testing web apps against different browsers is a waste of money if the code is correctly written by developers, who cost them an arm and a leg. But we know that blunders happen, and even code written by top-notch engineers demands refinement by a scrupulous QA team. Of course, if your aim is to bestow the opportunity to enjoy your web app on Chrome users only, skip this article alltogether. For all the rest who wish to reach a diverse audience with a variety of browser preferences, we’ve prepared this guide on the best testing tools and their new silver bullet – codeless automation testing.

By the way, pay attention here: we’re exploring the peculiarities of cross-browser and not cross-platform testing tools. Quite often, programs combine both of these types of testing because the behavior of an app inside a browser can be predetermined by the type of an operating system and its version. Still, there is a difference. Cross-browser testing concerns Safari, Firefox, Edge, and other browsers, while cross-platform testing checks how an app works across different operating systems: iOS, Android, Windows, and others.

The Essence and Goals of Cross-Browser Testing

An average user gives a web page 5 seconds to load and leaves it ruthlessly afterwards. Indeed, don’t we all become bad-tempered children in the online world, demanding apps to work flawlessly and throwing mental tantrums every time they don’t respond the way we expect? That’s why we can’t even try to eschew QA practices that ensure the impeccable online experience of our clients, and cross-browser testing plays a huge role here. It includes the assessments of the following elements of an app across different browsers and their versions:

  • functionality;
  • design and graphical user interface;
  • responsiveness;
  • accessibility.

After careful evaluation of each of the points, you will be able to unlock the following advantages for your web app:

Sublime User Experience and Performance

The main aim of cross-browser testing is to make sure your app works consistently and doesn’t change its functionality in different browsers. If a user can’t interact with your website on Safari, they probably won’t download another browser to use your app and will simply find another more convenient product.


Web-browser testing tools are frequently used to detect vulnerabilities and potential security breaches in various browsers. This will help to strengthen the weakest aspects of your app.


Leveraging a cross-browser tool aims to increase trust in your product because even minor incompatibilities can be interpreted as a lack of concern for clients.

3 Questions About Online Cross-Browser Testing Tools

Life was so simple when the only browser we had was Internet Explorer. But things have changed, and now, with a variety of browsers in use, we need to optimize and make every web app look appealing in each one. So, to help you get started with testing tools, we’ve prepared short answers to the who, how, and when questions about cross-browser testing.

When should cross-browser testing be performed?

Cross-browser testing can be performed at any point of software development, but, of course, everything has its perfect time and place. People frequently select one of the following times:

  • when a single page is ready;
  • when the whole app is built;
  • when the app is already released.

Which do you think is the best?

1… 2… 3...

Starting cross-browser testing as soon as possible is the most cost- and time-effective option. This approach complies with the DevOps culture so widespread these days and allows to detect mistakes and improve the code from the very start, leaving a bug zero chances to ruin a whole app.

Running tests when an app is already released can damage your reputation with many users encountering glitches, and changing the code of a ready app is extremely costly. But even this option is better than no cross-browser testing at all.

Who performs online cross-browser testing?

Well, traditionally, cross-browser testing is performed either by the development team or by the Quality Assurance team. For example, the CI/CD integration of cross-browser testing automation tools makes it possible for developers to send every chunk of code built for review immediately, ensuring a continuous testing approach.

Sometimes you don’t even need to know programming for this. Modern codeless test automation tools for modern web apps like DogQ provide project managers and business owners with the opportunity to conduct various tests themselves with intuitive design and simple navigation.

How to perform cross-browser testing?

Anything can be done with human hands, but aren’t machines more effective in, basically, everything? Fortunately, cross-browser testing is just the right task to allocate to algorithms. Though you can do it manually as well. Let’s take a look at both of them:

Manual Cross-Broswer Testing

This method, in which a human tester runs the same tests for different browsers over and over, requires more time and effort. In this case it’s also nearly impossible to test an app against a lot of browsers and every of their versions, so you’ll have to limit yourself with a couple of most popular ones. Here, we also shouldn’t forget about the tendency of a human to make mistakes when the work is monotonous.

Automated Cross-Browser Testing

Cross-browser testing that is automated does not require physically uploading different browsers, but rather runs test scenarios in a special tool. The speed at which most of the moden automated browser testing tools run thousands of tests is incomparable with the one of a human.

Speed and reliable test results are not the only advantages of automated cross browser testing. In fact, they often come packed with features so advanced that they help optimize the whole testing process and eventually ensure the high quality of an app. Let’s discover the best features of the tools for cross-browser testing automation through real-world examples.

Let’s start with the most striking pros of Appium: it’s a cross-browser testing tool, open source and free. With this tool, you can test web, native, and hybrid apps across iOS, Android, and Windows operating systems, and it supports most of the programming languages. But… It does require coding. It means that you’ll need to hire QA automation engineers to write test scenarios, so project managers, testers, and business owners can’t run tests independently. Moreover, these tests are difficult to maintain, especially if your app is constantly updating and scaling.

And how much is it?

The tool is free
