    Cross Browser Testing assures the working ability of any website across all existing web browsers. We can also understand it as the compatibility of websites at various Web Browser. It is a kind of non-functional testing through which we test the functions and design of websites.

    Frequently used browsers are Chrome, Safari, Mozilla, and IE. Hence, the testing team tests newly formed websites over these browsers on priority. Also, here we will understand the concept of Cross Browser Testing.

    Things to be kept in mind while doing Testing

    Usually, we all come across issues where websites work fine at one browser but create an issue on others. For example, a website performs well at Chrome, but its designs get distorted at Mozilla.

    Hence to overcome the problem, testers verify the performance of the application across all the browsers.

    Testing the website at various combinations of Browsers and Operating Systems: – Testers check a website on all possible browsers such as Chrome, Mozilla Firefox, Safari, etc.

    Along with browsers, they also ensure performance across multiple operating systems. Also, they plan all possible combinations and execute their test cases.

    Testing on various Mobile Devices:

    Nowadays the majority of people are accesses websites through mobile phone. Hence testing team assures its performance on all the devices. Apart from that, the testing team maintains the responsiveness across all devices such as Tablets, Mobile phones, etc.

    Testing on Assistive Tools:

    IT world has made these tools for the easiness of differently-abled people. Hence we verify the compatibility of a website across these tools as well.

    Things to be kept in mind while doing Testing

    Just imagine what will happen if someone opens your website and it is taking 10 minutes to open? Furthermore, what will happen if the texts and images are overlapping? It all creates a poor impression only.

    Moreover, businesses create web or mobile platforms to showcase their online presence. If any web platform is unable to engage the users, it is of no use. Also, the website should be fast and appealing in order to get attention from clients.

    Hence cross-browser platform testing is one of the important activities. Cross Browser Testing highlights the bugs so that the development team could do the required rectifications.

    Cross Browser Testing is beneficial because it offers

    • Quick Loading of Website
    • Users Engagement
    • Responsive Designs
    • Visible representation of Texts, Images, Videos, etc.
    • Smooth working of attached functionalities.

    How to perform Cross Browser Testing?

    There is some set format based on which testers do cross-browser testing. If we follow the process, there will not be any scope of error. So, let’s understand the ways through which we should do testing.

    Collect the requirement document:

    Before testing any website, make sure to keep the requirement document. With the document, one can analyze the difference between the client’s expectations and the website. Testers share the gap between both the levels, and the developer does required modifications.

    Isolate the basic functionalities:

    Firstly, one should test the website at all combinations of browsers and operating systems. Also, the functionalities shall include the testing of

    • Dialogue boxes of the website.
    • Major functionalities that are expected by clients. It may vary from project to project.
    • Fields of the form.
    • Buttons, through which users navigate from one page to another. Apart from that, testers forget to test the back button sometimes. As a result, issues remain there. So do not forget to validate the back buttons.
    • Cookies of the website.
    • Loading and response time of website.

    Validate design of the web page:

    The quality team tests the layout of the website across all the browsers. Sometimes, a web page opens in one browser but not in another. Hence this phase of testing eliminates such issues.

    Responsiveness of the website:

    As we have mentioned earlier, people use the website through mobile-based browsers, and hence, testing the website on various mobile devices becomes mandatory. Also, the website should have the same appeal across all the devices and resolutions.

    Tips for Cross Browser Testing?

    Creating combinations of operating systems and browsers is not a cup of tea for everybody. Sometimes people find it very annoying and hence by keeping that in mind, we are sharing some tips.

    • Select 15-20 most known and recognized browsers of the world. Afterward, take only two operating systems, for example, Android and iOS. Now making combinations is not a big deal. Moreover, people are frequently using these two operating systems. After the testing, one will cover the major area of clients.
    • Furthermore, make a list of browsers through which people have seen your website. The analytic tool will help to get the details of browsers. Now perform testing through those browsers also.

    Cross Browser Testing is an integral part of any web product, without which a website cannot go live. Hence above-mentioned methods will help in performing Cross Browser Testing.

    Also, the process empowers a website and makes it appealing in front of the world. Moreover, we will keep you updated on more topics. Just be in the loop and feel free to contact, if any issue comes.

    How do you perform cross browser testing?

    Effective cross-browser testing involves defining target browsers and devices, choosing a method (manual, automated, or cloud-based platforms), executing tests, analyzing and reporting results, and retesting after fixes. This process ensures consistent functionality and user experience across various platforms, leading to a high-quality and polished product.

    How to perform cross browser testing in Selenium TestNG?

    For cross-browser testing with Selenium and TestNG, leverage TestNG's parameterization to define different browsers in your XML file. Your test script receives these parameters and dynamically instantiates the appropriate WebDriver (e.g., ChromeDriver) based on the browser name. Run tests with different browsers using separate tags in the XML, specifying the desired browser as a parameter value. This enables executing the same test script across various browsers for comprehensive testing.

    Which tool is best for cross browser testing?

    Open-source options like Selenium offer flexibility but require coding knowledge. Cloud-based platforms like BrowserStack and Sauce Labs provide ease of use and access to real devices, but come with subscription fees. Appium is an open-source option for mobile and web testing. Consider project complexity, budget, and technical expertise when choosing the right tool. Exploring and comparing options is recommended.

    What is the meaning of cross browser?

    Cross-browser means your website works flawlessly across different web browsers (like Chrome, Firefox, Safari) and devices (desktops, tablets, smartphones). It's like ensuring your website is built with "universal bricks" that function well on various platforms, reaching a wider audience and providing a consistent, positive experience for all users.

    What is cross browser testing in selenium?

    Cross-browser testing with Selenium automates tests using the Selenium framework to ensure your website functions consistently across different browsers like Chrome, Firefox, and Safari. You write test scripts that simulate user actions and run them on various browsers to identify any inconsistencies or errors. While powerful and customizable, Selenium requires coding knowledge and can be time-consuming to set up for multiple browsers.
