Cross-browser testing is a method used to assess how web applications function across different browsers, ensuring consistent user experience due to varying interpretations of JavaScript, CSS, and HTML. Automated cross-browser testing enhances accuracy, provides a competitive advantage by quickly testing across multiple environments, and reduces the workload on development teams. Key browsers to be tested include Chrome, Firefox, Internet Explorer, Safari, and Edge.

1. Cross-Browser Testing with Automation
What is Cross-browser testing?
It is a testing method wherein a web application or website is assessed to know how it functions
across different browsers. This is important because each browser interprets and renders JavaScript,
CSS and HTML differently, so that what works in one aspect might not work in another. This testing
method makes sure that the app or site works as intended for all users, regardless of the browser
that is being used for accessing.
The website's functionality is also verified especially when visitors access it through different
combinations and tools.
Following are a few key benefits of automated cross-browser testing:
1. The accuracy of the testing process is enhanced: When cross-browser functionality or
compatibility is tested manually, then there might be scenarios where human errors may occur. For
instance, a particular device or browser may have not been checked. Hence, automation testing
should be applied tactically.
2. Provides a competitive advantage: When different browser combinations, operating systems,
web app functionality on various devices, compatibility with assistive technologies etc., needs to be
checked, then the process can become overwhelming. For this purpose, when the process is

2. automated, then the web app can be quickly tested on different devices and browsers without
having to do it manually each time.
3. The workload is reduced: Development teams already have a bevy of tasks to work upon. They
must make sure that the new features do no break the existing functionality, bugs need to be fixed
and code needs to be worked upon accordingly. Hence, this is where cross-browser automation
testing comes into perspective.
When the process is automated, then the workload of the development teams is reduced to a great
extent. Automation testing will take upon a huge lot of testing tasks. This will help the development
team to focus their expertise on other important testing and development activities.
4. The functionality of popular browsers is tested: Chrome, Firefox, IE, Safari and edge are the most
commonly used browsers. The functionality of web applications needs to be tested on these
browsers as a huge lot of people use these browsers frequently.
