Top 8 Cross-browser Testing Tools For Mobile & Web

Cross-browser testing tools featured image

Admittedly, Chrome is the dominating browser with around 62.3% of market share as of Nov 2023, but if you only test your websites on Google Chrome, there is still around 38.7% of your users who visit  your site on other browsers that you are missing out on. What if a bug occurs on those browsers? To ensure that no bugs went undetected, you need cross-browser testing.
 

To test across browsers, you may need a cross-browser testing tool. Without such tools, you need to constantly switch from one browser/device/OS to the next for the same test case. 

 

With a good tool, you can easily configure those test cases to run automatically across the environments of your choice, which is way more efficient than manual methods. In this article, we have listed down the top cross-browser testing tools for your QA team to consider. Make sure to choose a tool that aligns best with your team's needs, resources, and technical expertise.

 

Benefits of Adopting a Cross-browser Testing Tool

Cross-browser testing is, in fact, a much smaller subset of cross-platform testing, which involves testing across browsers, operating systems, devices, and their legacy versions. A different combination of these provides a completely different experience. Currently we have around:

  • 9000+ different devices
  • 21 different operating systems (including older versions)
  • 6 major browser engines (Blink, WebKit, Gecko, Trident, EdgeHTML, Chromium) powering thousands of browsers (Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge, Opera, etc.) 

Together they make up thousands of device - OS - browser combinations that you have to take into account.
 

Without a cross-browser testing tool, the QA team has these options:

  • In-House Device Labs: some QA teams set up in-house device labs with a variety of physical devices and browsers ready for testing purposes. This also means investing into physical machines supporting combinations of browsers the team wants to test on. This approach can grow to be quite costly, and the effort to maintain those devices for most accurate test results is never small.
  • Cloud Testing Devices: QA teams can leverage cloud-based testing devices to provide immediate access to virtual environments for a wide variety of browsers and devices. This eliminates the need to maintain an extensive physical device lab. However, a cloud testing service is external, and therefore disconnected from your internal testing activities, leading to challenges in management.
  • Emulators and Simulators: another good option is using emulators/simulators to mimic the behavior of different devices and browsers. These tools are often part of integrated development environments (IDEs) or available as standalone applications. Their downside also happens to be the lack of connection with other testing activities.

A good cross-browser testing tool solves those challenges by unifying all those features in one place. When choosing a tool, you should look at these criteria:

  1. Does the tool support the on-cloud testing of browsers/devices/OS/versions that you need?
  2. Does the tool connect your cross-browser testing activities with other testing activities?
  3. Does the tool offer adequate CI/CD integrations?
  4. Does the tool provide user analytics/monitoring for continuous feedback and insights? 

The questions above should provide you with a good starting point. Now, let’s look at the list of the top cross-browser testing tools in the current market. We compare them in detail, listing down their notable strengths, their key features, pricing point, and even link to their websites/documentations for your convenience. 
 

With that being said, here is our list of the top 10 cross-browser testing tools that we have carefully selected based on the aforementioned criteria:

2. Selenium [Best Framework For Cross-browser Testing]

Selenium as a good framework for cross-browser testing

Selenium is undoubtedly one of the first choices when it comes to cross-browser testing thanks to its well-known versatility. Selenium supports multiple programming languages, including Java, Python, C#, Ruby, and JavaScript. This flexibility allows testing teams to leverage their existing skills and choose a programming language that aligns seamlessly with their expertise.
 

This versatility extends to various browsers, including Chrome, Firefox, Safari, Internet Explorer, and others. Selenium's WebDriver API enables tests to be executed across different browsers without major modifications, ensuring cross-browser compatibility.

For example, let’s look at a code snippet written in Java using Selenium to test on both Chrome and Safari. The testOnChrome and testOnSafari method is a test case for the respective browser.
 

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.safari.SafariDriver;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;
 
public class CrossBrowserTest {
 
    private WebDriver chromeDriver;
    private WebDriver safariDriver;
 
    @BeforeClass
    public void setUp() {
        // Set the system property for ChromeDriver
        System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");
 
        // Initialize ChromeDriver
        chromeDriver = new ChromeDriver();
 
        // Initialize SafariDriver
        safariDriver = new SafariDriver();
    }
 
    @Test
    public void testOnChrome() {
        // Navigate to a website
        chromeDriver.get("https://www.example.com");
 
        // Perform your test steps on Chrome
        // …
 
        // Add assertions or verifications as needed
        // ...
    }
 
    @Test
    public void testOnSafari() {
        // Navigate to the same website
        safariDriver.get("https://www.example.com");
 
        // Perform your test steps on Safari
        // …
 
        // Add assertions or verifications as needed
        // ...
    }
 
    @AfterClass
    public void tearDown() {
        // Close ChromeDriver
        if (chromeDriver != null) {
            chromeDriver.quit();
        }
 
        // Close SafariDriver
        if (safariDriver != null) {
            safariDriver.quit();
        }
    }
}
