What is Cross Browser Testing? A Complete Blog Guide .

• A Comprehensive Beginners Guide to Cross Browser Testing:

We all might have examined that some websites are not appropriately displayed on some browsers and we instantly comprehend that the website is broken. But, as quickly as you open it on a different browser, the website opens up nicely. Thus this aspect illustrates the compatibility of a website with numerous browsers.

• Cross Browser Testing

With the improvement in technology, there are numerous alternatives accessible for browsers, and it’s not just sufficient to create a website work on one of the browsers. Users should not be prohibited to utilize any particular browser to access your application. Therefore, it becomes crucial to test your website’s compatibility with numerous browsers. Some of the generally utilized browsers comprise Chrome, Safari, Firefox, Internet Explorer, etc.

• What is Cross Browser Testing?

#1) Cross-browser testing is completely what its name implies – that is, to test your website or application in numerous browsers- and making sure that it functions invariably and as planned without any dependences or compromise in Quality.

#2) This correlates to both web and mobile applications.

#3) What kinds of applications undergo this? – Customer-facing applications are a decent selection. You might marvel at this point, “Aren’t all applications customer-facing?” Well, yes. They are. Still, let us glance at a few example.

Application 1: An application created for an organization to internally maintain track of its inventory.

Application 2: This is for the end-users to purchase products from this organization

The best notion would be to test Application 2 for browser compatibility testing since it is absurd to regulate what browsers/platforms/versions the end-user is going to utilize.

On the different hand, if all computers internal to the organization utilize  Windows 8 machines with Chrome browser- then there is no necessity to glance or test for anything else troubling Application 1.

• Why Is It Performed?

For that matter, why is any sort of testing performed?

1) To know what is erroneous and be able to rectify it.

2) To strengthen efficiency and user experience and thereby, company.

3) To be notified of any probable hitches

• But precisely, if we think: What is the objective of cross-browser testing? – This is twofold.

The version or appearance of the page in several browsers- is it similar, is it distinct, if one is better than the other, etc.

• Who Executes This Testing?

1) The whole project team should have a capitalized interest, time, wealth, and infrastructure to fund this endeavor.

2) The QA team can be implicated in this procedure or it might be the design team who are keen on understanding how the application fares in numerous browsers.

3) Whether it is executed by QA or any different team- the outcomes are comprehended by the design and development teams and the pertinent changes are rendered.

• How to Perform Cross Browser Testing?

Now we are discussing this!  First things first- is it done manually or utilizing a tool?

It can certainly be executed manually- numerous machines, huge OSs, Multiple browsers, many machines, and but simply, this leads to many problems, considerable investments, and numerous challenges.

• Cross Browser Testing categories -

1) Manual Method

In this case, a company recognizes the browsers that the application must help. Testers then re-run the similar test cases utilizing numerous browsers and investigate the application’s behavior and reveal bugs if any.

In this category of testing, it is not feasible to cover several browsers, and the application might not be tested on major browser versions. Furthermore, executing cross-browser inspections manually is expensive and time-consuming too.

2) Automated Method

Cross-browser testing is operating a similar set of test cases numerous times on several browsers. This category of rehearsed tasks is nicely suited for automation. Therefore, it’s more cost and time effective to execute this testing by utilizing tools. So, plenties of tools are accessible in the market to make this manageable.

The tools enable us with one or more or all of the following relying on the tool itself and the licensing categories :

• They give a VPN (Virtual Private machine) utilizing which you can bind to remote machines and test the working and performance of your JAVA, AJAX, HTML, Flash, and additional pages. Most of these are secure, but since you are delivering your data to a third party, a specific analysis on discretion is informed.

• Screenshots are given for the pages and links submitted of how they appear in numerous browsers. This is, of course, static.

• Multiple browsers are synchronized concerning operations executed on one and the outcomes are illustrated browser-.

• Show the rendition of a page at numerous screen resolutions

• When a difficulty is discovered, a video or screenshots are recorded to transfer the difficulty for more analysis.

• Support commonly is accessible for both web and mobile apps

• Private pages that impose authentication to be accessed can furthermore be tested

• Local, within a private network/firewall pages, can be tested too

• When to Start This Testing?

The moment to begin a Cross-Browser test completely relies on your testing methodology and your testing timeline.

This test can be executed :

#1) As soon as possible:

Commence this testing even when a single page is prepared for testing.

Test that page on each browser. When the next page is accessible, test that moreover on numerous browsers. This will boost the efforts, but it will enable to rectify the mistakes as early as possible in the life-cycle. Therefore, fixing errors, in this case, is much cost-effective.

#2) When the application is comprehensive :

Onset this testing when the application development is complete.it will test the application as an aggregate on various browsers. Remedying the blunders won’t be as cost-effective as in the above case but it will still help in fixing the errors before releasing the application to the users.

#3) When the application is broadcasted:

This is the least favored time for executing a cross-browser test for your application. But it’s reasonable to perform it than to not performing it and allow the end-users to have a horrible experience.

After the application is disclosed for the end-users, this testing can be executed and bugs can be overhauled as a part of the transition requests in the application. This is very expensive and imposes numerous deployments relying on bug fixes.

Severe cross-browser testing can only be achieved when the testing team members who know do this testing. high-level or checking some particular browsers can furthermore be executed by company users or even developers.

This testing involves testing the application completely utilizing several browsers. Testing thoroughly contains functional and non-functional testing of the application.

In maximum organizations, the brand product has different teams for functional and non-functional testing. Therefore, this testing requires to be executed by the team(s) who is (are) credible for functional and non-functional testing of the application.

For this testing, a tester requires the browsers on which the application needs to be tested. These browsers can either be given to the tester as:

• Locally introduced on tester’s machine.

• A virtual machine or several machines  which have access

• Tools that provide users and their different versions for testing.

On cloud – so that numerous testers can utilize the browsers as and when expected. This testing is autonomous of the deployment climates. Therefore, it can be executed in test, QA prevents production environment banking upon the availability of the application in each of these atmospheres.

• What to Test?

1) Base Functionality: Links, dialogs, menus, etc.

2) Graphical User Interface: Look and feel of the application.

3) Response: How well the application acknowledges user actions.

4) Performance: Loading of the pages within the authorized time frame.

If your application functions well on one browser, that doesn’t suggest that it will function well on the other browsers too. Therefore, this testing enables you to assure that an application runs on several browsers without any fallacies. To recognize what breaks on which browser and to fix the website, therefore, we need to execute this testing. If a browser is not at all supported, then the users can handily be acquainted with it.

• To summarize “how” to cross-browser test

#1. Traffic statistics help specify what browsers to test.

#2. A detailed inspection should be executed on the AUT (Application under test) itself to determine what portions of the application or if all of it has to endure this. All of it should be tested on numerous browsers, but again expenses and time have to be contemplated. A good technique is to execute 100% testing on one browser per platform and for the other just test the most crucial and widely utilized functionality.

#3. Once the judgment of “What” to test and “Where (browsers)” is made- infrastructure decisions are to be made- do we amass tools or perform this manually etc. Again, the expense has to be contemplated. Viability, risks, security concerns, people to be implicated, time, acceptance criteria, issue/defect fixing schedules/process – are few things that have to be communicated.

#4. Perform the testing. The conventional functional testing test cases can be utilized when verifying the efficiency of the system. For look-and-feel/rendition test cases are not crucial.

#5. Report the results back to the design team, if they were not entangled in the testing procedure. Change follows.

• When is the best period to do this?

Any testing reaps the promising advantages when it is done early on. Thus, the industry suggestion is, to begin with, it as soon as the page designs are accessible.  But it furthermore can be executed when the site is completely integrated and practical.

If you have skipped the bus on performing the cross-browser test during the design, development, and QA phases, it can however be executed while the application is in production. Still, this is the expensive of all and unpredictable too.

• Where is browser compatibility testing executed?

Usually, the explanation to this question would be one of- Dev/QA/Production environments. But for cross-browser checking, this is not substantial. It can be executed in any one or all of them.

Conclusion

Cross-browser testing enables in development of a promising impression on the users by giving them a compatible experience throughout the application irrespective of the browser or Operating system. Overhauling bugs is cost-effective during the early phases of the growth lifecycle, and the same applies to the deformities found as a part of this testing too.

As you know, every category of testing enables in enhancing the quality of the application and so does the cross-browser test too. This testing enables in enhancing your company which in turn results in Happy clients, Happy You!!
