In this article, you will see what automation testing is, why we need automation in cross-browser testing, and how automation testing is revolutionizing cross-browser compatibility.

What is Automation Testing?

Automation testing is a software application or website testing technique using automated tools and frameworks for some specific testing goal. It is different from manual testing as in manual testing, the testing is done by the manual efforts to write the test cases and test execution. Automation testing does not require that much human involvement to perform cross-browser testing. The automation testing software can also enter test data into the System Under Test, compare expected and actual results, and help generate detailed test reports. Software applications or website test automation require a lot of money and resources.

When you perform cross-browser testing, your website must be tested against many web browsers and their versions. It’s like a huge task to perform them one by one manually. So, here comes the use of Automated cross-browser testing. Automated cross-browser testing is testing websites or software applications against various types of web browsers and their versions using more automated tools and technologies rather than manual efforts, which is a very time-consuming task.

Automated cross-browser testing tools help to execute testing on real-time devices with different resolutions, configurations, and browsers. These automated tools also support visual testing, functional testing, regression testing, etc. They allow CI/CD integration and parallel testing. All these advanced and automated cross-browser testing features help execute the testing efficiently in less time and cost.

How Automation Testing is Revolutionizing Cross-Browser Compatibility?

Let us see the various points of how automation testing is revolutionizing cross-browser testing.

  • Expanded Test Coverage

Achieving effective and comprehensive test coverage is a major challenge in cross-browser testing. Expanding your test coverage for cross-browser testing is a complex task, particularly when using a manual testing approach. Automation testing helps a lot in expanding your test coverage. Test coverage is defined as the configurations, types of devices, and browser-OS combinations for which you can test your mobile app.

The testing coverage increases when you perform software testing using parallel or distributed testing on more and more devices simultaneously. It also helps to ensure that the software experience increases and the end user gets the best possible experience while using the application. Various test automation tools help augment test coverage and simplify testing complex features such as UI features, databases, and servers.

  • Early Bug Detection

Automation testing helps the QA team and developer team by detecting bugs at an early stage. In automation testing, the testing team can run the unit tests before submitting the codes, followed by other automated tests such as regression and integration testing. It makes it possible to detect bugs and errors at an early stage. And early detection of errors and bugs is easy to fix with minimal impact.

This aligns with the shift-left testing strategy, which aims to identify and fix these errors and bugs early in development. Fixing bugs at an early stage improves the software quality and reduces issue resolution time later in the pipeline. In this way, automation testing helps in early bug detection and revolutionizing cross-browser compatibility.

  • Increased Accuracy

Manual testing is done by human involvement; these approaches are more prone to mistakes. Automation cross-browser testing executes the test scripts more accurately and records detailed test results and analysis. Automation testing to check cross-browser compatibility ensures high testing accuracy by decreasing human error.

Human errors in cross-browser testing occur due to various factors such as fatigue, oversight, and other human factors.

Automation testing can provide more accurate and efficient reports than manual cross-browser testing. It’s also a different kind of data – a human will describe their experience of your app, which is more subjective and less detailed but matters greatly – especially for bugs a machine can’t pick up. All these reasons show how automation testing helps to enhance testing accuracy and revolutionize cross-browser compatibility.

  • Increased Consistency

In cross-browser testing, the lack of testing consistency and standardization causes some essential issues and bugs to be missed. Automation suites are indispensable in continuous testing scenarios, such as triggering regular regression test runs. In automated cross-browser testing, test cases get executed similarly on each iteration of the testing process. You can also run these tests daily, ensuring any new errors or bugs get easily fixed. It leads to improved confidence in the website or web app quality.

  • Cost Savings

The websites or web apps with advanced infrastructures see the highest automation ROI. In automation cross-browser testing, it is seen that the cost of testing is less. It is not only about software test automation; setting up and standardizing automated workflows doesn’t happen overnight. However, long-term ROI in accuracy, speed, and consistency is guaranteed. There are various cloud-based automated tools that are used by the QA team and development team to perform cross-browser testing.

These cloud-based automated tools help save costs as you only have to pay for those resources you use. Also, you can increase the scalability of the test.
