10 Best Cross-Browser Testing Services

Best Cross-Browser Testing Services

Diego Asturias

Web browsers and devices render websites and web apps UIs in different ways. For instance, a 1080p Windows desktop screen using Google Chrome in South Korea would likely display a website in a particular way. But, when you open the same website using an iPhone with a Safari web browser, the results are likely to be different in a mobile located in Brazil.

These visitors may see different form fields, and their cookies may be handled; differently, the website layout may change drastically, orientation may work differently, and the visitor would expect a specific language. It can be pretty challenging to ensure that all these elements provide a similar output and that the visitor has a good experience. However, this is precisely what cross-browsing and cross-device testing solve— they ensure that these renderings are as identical as possible on all devices. 

In this post, we will go through the top ten best cross-browser testing services and products.

Cross-Browser Testing Services and Products

Although the term “cross-browser testing” would indicate that these tests are only performed on browsers, in general, the term also extends to cross-device testing. As of July 2021, the number of mobile device sessions has surpassed the number of desktop device sessions. So, it makes sense to render web apps and pages using a combination of browsers, devices, and OSs.

What’s cross browsing testing? Cross-browser testing is a non-functional test that aims to check a specific web application or site against different web browsers and devices. The test aims to find usability, compatibility, or visual inconsistencies failures. Cross-browser tests provide confidence that a web app and site display and works as they should when accessed through a combination of browsers, OS, and devices. Such tests may also provide an independent view of the application’s status so that business owners have more decision power to either release or withdraw a new version or feature.

What is covered during a cross-browser test?

  • Verify that basic functionality works as intended This includes dialog boxes, menus, form fields, first-party cookies handling, and touch input from mobiles and tablets.
  • Check visuals and design A cross-browser test also helps ensure that the website appearance (layout, fonts, images) matches the web design requirements.
  • Verify a website's accessibility A cross-browser test helps verify whether the web content is accessible to people with disabilities. This is useful for helping ensure compliance with the Web Content Accessibility Guidelines (WCAG).
  • Assess the website's responsiveness Verify whether the web design is fluid and adjusts appropriately to different screen sizes and orientations.
  • Verify geographical access A cross-browser test also helps verify how a website looks in the eyes of a different geographical audience. Check translations, timezone, and currencies.

Who uses cross-browser testing?

Cross-browser testing services can be used by anyone developing a website or web app. Generally, a cross-browser test can be performed during the last phases of development, testing phase, or post-production. Web developers can continuously test Graphical User Interface, compatibility, and functionalities as web developers create different elements. Front-end web designers can use it to analyze and fix the visual elements.

QA engineers may also benefit from cross-browsing testing services. They take development projects and perform exhaustive tests and analyses to assure quality. QA engineers may also check content, layout, responsiveness web design, website or app usability, accessibility, integrations, input such as touch and keyboard, and more.

What to look for in a cross-browser testing service?

Modern, cross-browser testing products and services may offer any of the features below:

  • We have automated UI cross-browser testing.
  • Grid testing to run simultaneous tests on a collection of devices, OS, and browsers.
  • Comparison of web browsers, OS, and devices in parallel.
