cross browser testing
The name of this testing type speaks for itself: it's needed to check how your app will operate on different browsers. The main point here is to find differences and issues in behavior of the app. It includes everything from loading times to CSS styles rendering and functionality testing.
why is it important?
For you as a software developer the goal is to deliver a product that can be used as wide as possible by maximum amount users on maximum about of platforms. And it does not stop there, each browser has a bunch of versions that my or may not operate differently depending on a large amount of external and internal factors. For example, old IE versions are notorious for browser compatibility issues.In addition to that, even the same version of one browser may operate differently on different OS iterations which also needs to be taken into account.
The process of cross browser testing takes a lot of time even if you know the right tools and how to operate them. Most of external QA teams do not have either time or skills to correctly execute cross browser testing on your app and compile an easy-to-read and transparent result. This is why if you need assistance in this type of testing and you are looking for an external team that can do that for you, you definitely should consider DeviQA`s cross-browser testing services.Our teams can prepare all needed documentation, make some market research and provide you a clean, laconic report.
what are the right tools?
There are a lot of different tools that you can use for cross browser testing and only experienced teams have the right, fast and relatively low time-consumption approach. Here are the tools we are using and would recommend everyone else to do so:1. First of all, if you have a reasonable selection on browsers to test on, for example Chrome, Firefox, Safari and IE it's always better to use real machines with real operating systems. One, because this info will be as valid as it gets. Two, because that is what your target audience will be using. It does not take too much resources to get those and definitely always pays off.
2. In case you are limited in some way, there are a lot of web tools that allow great selection of browser versions and even mobile devices you can check your app on.Best example of such tool is Browserstack.
This is a paid service that provides you access to a great selection of mobile devices as well as operating systems you can test on. Its great for any type of web application as long as it does not involve video or audio calls which Browserstack does not allow. In addition to that, they are using real mobile devices unlike most of similar services that are using emulators. Oh, and they also have a desktop application!
This one is an easy-to-use tool that allows you to take screenshots of your website on different browser versions and gather them all in one place. The good things about it are that its free and you do not have to do anything but pasting a link, checking right versions and clicking one button. After a short time you will get your screenshots and will be able to compare them no problem. Also it provides Linux, Windows and MacOS selection which is just great for a free tool.The downside is that you will not be able to operate any feature of the app and in case you need to login or provide any sort of confirmation to open the page, you will not be able to do so unless you provide a link with a token.
