How to Test a WordPress Site in Different Browsers

How to Test a WordPress Site in Different BrowserAre you planning to change your WordPress theme, or trying to add some more forms and tables? Are you worried about your website design and the changes that might occur in the design? You might be sceptical about whether the new website design is uniform and all the users with different screen sizes, os, browsers, and devices are having the same user experience or not. If this is the case then definitely your WordPress website needs cross-browser testing. In this blog, we will have an overview of cross-browser testing and its needs for testing different types of websites.

What is Cross Browser Testing?

In cross Browser testing, we test a website or mobile application across various combinations of device, os, and browser in order to measure the compatibility. It also analyzes whether the application works as intended across all the devices, screen sizes, browsers, and operating systems. 

The need for testing website across different browsers

As per the statistics, google chrome is the most widely used browser with a 65% market share on desktop computers and 57% of market share on mobile devices.

However, other browsers like firefox, internet explorer, safari, opera, Microsoft edge are still in use by hundreds and millions of users across the globe. In order to match the compatibility of your website across various browsers, cross-browser testing is a must!

Nowadays, cross-browser testing is a very important part of building websites. It provides a wide range of browsers, os, screen sizes, and devices. Cross-browser testing ensures a consistent web experience across different devices, browsers, and platforms.

Though all the popular websites behave identically while rendering a website, all the browsers use different code and also go through frequent updations which might lead to handling the web elements differently from time to time. This seriously affects the compatibility of the website across various browsers and your website might look different in different browsers. As these are not WordPress issues, you might not realize your error until someone reports it. Hence it is highly recommended to cross-browse the WordPress site to confirm what the website offers.

For understanding whether the website is functioning as intended in all the browsers and devices, we need to perform cross-browser testing. So we have a number of cloud platforms where adding and removing devices as well as performing parallel and automation testing would be a matter of just a few clicks.

But before performing testing, the best practice would be to make a list of all the browsers, os, and devices that would be required for testing. To do so, we need to know the browsers and devices used by your target audience. So let’s understand how we can do this?

How to know which devices and browsers to use?

Before preparing the test scripts for cross-browser testing, one should prepare the list of browsers and devices to be used. To find which browsers and devices are being used by the target audience we can use Google Analytics Report. 

In google analytics, we can find out the complete list of devices and browsers used by the users.

For finding the type of mobile devices, as shown in the figure below, under the audience on the left-hand side, mobile and then device, you can check all the mobile devices used by your customers.

Similarly, for finding the types of browsers used by the users, as shown in the figure below, under the mobile and overview and setting the secondary dimension as the browsers, you can get the list of all the browsers used by your audience.

Cross Browser Testing in a WordPress Site

Once you have the list of all the browsers and devices, you can go ahead and make different combinations and run cross-browser test scripts. Now let’s discuss the best cross-browser testing tools 

Best browser testing tools for testing WordPress websites

In cross-browser testing, we have to run the same test cases multiple times. That’s the reason it is impossible to execute cross-browser testing manually. Hence using automated test scripts for cross-browser testing is an ideal practice.


The most popular tool for executing cross-browser testing is Selenium. One of the greatest reasons behind its popularity is that it is an open-source tool, hence free of cost. It supports all programming languages, has a huge community consisting of top-notch testing and practitioners. Selenium has different versions better than the previous ones. It is just not a single software but a testing suite consisting of many tools like Selenium Web driver, selenium grid, selenium IDE, selenium RC. Out of these both Selenium Grid and Selenium Webdriver are favourable for cross-browser testing for word press sites. Let’s have an overview of the architecture of Selenium Webdriver and Selenium Grid. 

Selenium Webdriver 

The Selenium Web Driver architecture is shown in the figure below :

The Selenium Web Driver Architecture consists of the client and the server. On the client-side, we can write the test scripts in any programming languages like Java, Javascript, C, C#, Ruby, PHP, etc. This entire test script is converted into the JSON format. The JSON wire protocol enables communication between the client and the server. The JSON wire protocol is available to the browser drivers through HTTP format.  The browser drivers interpret the JSON and execute commands. 

The browser drivers use these commands to run them on the browsers. In this way interaction between the browser driver and browser takes place to test multiple browsers simultaneously. Hence selenium web driver is the best tool for browser testing. 

Selenium Grid

If you are looking to run your testing scripts on multiple devices in parallel then you should certainly go for the selenium grid testing tool. 

The selenium grid allows executing web driver scripts on multiple devices in remote by routing commands sent by clients to the remote browser instances. It enables us to run tests in parallel on multiple devices. 

As shown in the  figure selenium grid consists of Hub and Grids 

Hub: The hub accepts instructions from the web driver client and performs routing of commands in the form of JSON wire protocol to all the browser drivers in the node. It actually takes the access request from the web driver client and executes them remotely on various nodes in parallel 

Nodes: Nodes are the machines or the browser drivers connected to the hub where the hub executes all the commands on these nodes. The nodes receive commands in the form of JSON test commands and execute them using a web driver.

The advantage of using a selenium grid is that it makes cross-browser testing easy by executing a single test on multiple devices and browsers simultaneously. It also makes analyzing and comparing the test results easy.

Hence selenium grid is the best choice for reducing time and labour for cross-browser testing 


pCloudy is a cloud-based continuous testing automation platform for testing both mobile and desktop web applications. It consists of two independent clouds consisting of multiple devices for achieving compatibility with almost all devices in the target market. The device cloud consists of 200+ mobile device browser combinations. The browser cloud consists of 2000+ desktop device browser combinations for achieving accurate results for cross-browser testing. IT supports a number of best test automation frameworks like Selenium, Appium, Robotium, Espresso etc to perform high quality and accelerated test automation. Also, it consists of many futuristic features like local site testing to make testing simple and seamless. Hence these features make pCloudy the best platform for testing your WordPress applications. It functions well in a mobile app or web app!


We know how dynamic the application industry is where everyday new device versions, os versions and browser versions are releasing. This might affect the user experience of the applications across different devices. As these are not WordPress errors that cannot be detected without testing, cross-browser testing is a must. There are a lot of tools to support cross-browser testing. So, choosing cloud platforms is the best because of its numerous advantages. So do make sure to cross-browser test your WordPress site.
