Consider an internet site as a recipe in your home made chocolate chip cookies. Cross browser testing is like making an attempt out the recipe in a number of kitchens with completely different home equipment and substances.
It makes positive the cookie recipe tastes constant and nice whether or not it’s baked within the Chrome, Firefox, or Safari kitchen.
It is an essential a part of high quality assurance when coping with web sites and apps, and this information offers you an summary.
To assist in the writing of this piece, I interviewed Dmitriy Borisov, one of many QA Engineers right here at Semrush.
Why is Cross Browser Testing Wanted?
Once you’re making chocolate chip cookies, completely different ovens or cookie trays can get hotter and prepare dinner quicker or slower than others.
Like home equipment, completely different browsers have their distinctive rendering engines and options. These distinctive options may cause inconsistencies in the best way your web site seems and capabilities.
For instance, a webpage that hundreds completely on one browser may take longer to load or seem incomplete on one other.
Elements that would result in an app or website rendering in a different way embody:
- Totally different browsers (Chrome, Edge, Safari)
- Totally different variations of the identical browser
- Working techniques* (MacOS, Android)
- System sorts (smartphones, tablets, and laptops with completely different display screen sizes)
- Community situations (various ranges of community velocity or reliability)
* Testing throughout completely different working techniques can be known as cross-platform testing.
Cross Browser Testing Definition
Usually carried out by QA engineers, cross browser testing is the follow of evaluating an internet site or app’s performance and compatibility throughout a number of internet browsers.
This check ensures a constant and seamless consumer expertise, figuring out and addressing potential points which will come up on account of browser variations.
When you’ve run a cross browser check, you’ll know if it’s essential make any developmental adjustments to ensure your website runs easily all over the place.
Carry out Cross Browser Testing
To carry out cross browser testing, it’s best to first establish your objectives. Widespread objectives of cross browser testing might embody:
- Validating that the system being examined meets expectations
- Figuring out points with particular browsers
- Replicating and validating any difficulty
- Testing potential fixes to the problem
So as to validate points and check potential fixes, you’ll have to arrange your testing atmosphere.
There are numerous instruments and strategies you should utilize to carry out cross browser testing, together with guide testing and automatic testing.
Setting Up a Cross Browser Testing Setting
A cross-browser testing atmosphere is the platform the place improvement groups assess the efficiency and performance of an internet site or app throughout varied browsers.
That is your managed house designed to duplicate real-world situations, permitting for complete testing and guaranteeing compatibility with varied browsers.
This atmosphere could be arrange manually, however with the assistance of instruments, you will get this performed quicker and at scale.
Select the Proper Cross Browser Testing Instruments
There are a number of cross browser testing instruments and platforms out there to strive. Some we will suggest embody:
- Web site Testing (within the Semrush App Middle)
- Cell App Tester (within the Semrush App Middle)
- BrowserStack
- Playwright
- Selenium
- CrossBrowserTesting
- LambdaTest
Every instrument has its personal benefits and downsides. That you must select the one that matches your necessities and funds.
Configuring Take a look at Platforms
When you’ve chosen your instrument, you’ll have to configure your check platforms. Take a look at platforms are the mixture of browser and working system that you just need to check your web site or software on.
You must select the check platforms based mostly on the gadgets and browsers that your audience is utilizing.
For instance, in case your audience is utilizing Home windows, it’s best to check how your website seems on browsers like Microsoft Edge and Chrome on Home windows working techniques.
With the Web site Testing App, you may select from any of those environments to check your URL:
Deciding on browsers to check with the Web site Testing app
What you are able to do right here is choose all the variations of browsers and working techniques which can be essential to your check. Then, merely hit the “Begin Browser” button to check the URL on every browser.
Take a look at Execution and Reporting
Operating Checks Throughout Totally different Browsers
When you’ve outlined your check goals and created check circumstances, it is time to run checks throughout completely different browsers and cell gadgets. Use a cross-browser testing instrument to automate the method and save time.
Whilst you might need to check your website on the preferred browsers on the planet, it is essential to check your web site or internet software on the browsers that your supposed viewers is on.
If most of your customers are on Google Chrome, it’s best to check on variations of Chrome. It might be tempting to see how nicely your website or app holds up on older browsers, however it’s not all the time needed. Possibly most of your customers are on Edge. In that case, testing on Edge could be extra essential.
Analyzing Take a look at Outcomes
After operating checks, it is time to analyze the outcomes. Some cross-browser testing instruments generate detailed studies and screenshots that present whether or not your web site or internet software appeared accurately. These studies will help you establish points and bugs that should be mounted.
For instance, right here’s what the Web site Testing app exhibits when operating a visible testing atmosphere for a number of browsers:
An instance of a cross browser visible check with the Web site Testing app
As you may see within the picture above, the webpage hundreds very in a different way on every browser, and barely in any respect on just a few (IE 11 and IE 8). You’ll be able to open up any screenshot right here to take a better look whereas visible testing.
When analyzing check outcomes, take note of the next:
- Browser-specific points: Search for points that happen on particular browsers and variations. These points could also be associated to browser compatibility or performance.
- Practical points: Search for points associated to the performance of your web site or internet software. These points could also be associated to consumer interface, navigation, or type submission.
- Efficiency points: Search for points associated to the efficiency of your web site or internet software. These points could also be associated to web page load time or responsiveness.

In conclusion, operating checks throughout completely different browsers and analyzing check outcomes are important steps in cross-browser testing. Analyze check outcomes to establish and prioritize points that should be mounted.
Challenges and Greatest Practices
Widespread Points in Cross Browser Testing
Cross browser testing is an important a part of internet improvement. Nevertheless, it may be a difficult process as a result of huge variety of browsers and gadgets that exist available in the market. Listed below are some frequent points that you could be face whereas performing cross browser testing:
- Browser compatibility points: Totally different browsers have completely different rendering engines, which can trigger variations within the look and performance of an internet site.
