A complete guide on Device Compatibility Testing

By techbuddysorg

When it comes to developing apps and websites, device compatibility testing is one of the most integral components.

This functionality testing ensures that your web applications are compatible and friendly both with desktops and smartphones.

To meet the deadlines, testers tend to follow the approach of automation testing to ensure compatibility.   

Furthermore, a well-tested software program is what every business person wishes for. This is because it allows a brand name to buy more customers and keep its existing clients.

Despite the fact that software developers will always do their best to meet your needs and specifications, sometimes you have to go on your own to ensure that everything works as it should.

Introduction to Compatibility Testing

As the introduction states, compatibility testing is a particularly interesting method of software testing.

The work that the testers do here is similar to what is done during the functional testing stage in terms of the processes and procedures. 

  • The testers available for compatibility testing are different from the functional testers in that their tests are based on how different types of systems are able to communicate with each other. This is an extremely crucial part of the development and QA process, as compatibility issues can be sorted out at this stage rather than further down the long road of development. 
  • Device compatibility testing is a necessary step if you are going to develop digital solutions. Checking the compatibility of your sites and applications should be an important part of the development process. Since the early days of the Internet, online businesses have been competing for customers and for customers’ attention.

An application, system, or site that is going to be used on multiple devices can cause a whole lot of problems with users if it’s not compatible.

Compatibility testing essentially ensures that the interface looks and acts the same each time it’s used no matter which device is being selected.

Advantages of performing Device Compatibility Testing

Compatibility testing is essential for any kind of site and applications that use multiple hardware, browsers, and operating systems.

Testers are the most qualified persons for this job and developers do the coding according to the output result of testers but practice a compatibility test on each browser for those browsers that are popular to make sure that the site is working fine in all browsers and OS.

Moreover, the advantages associated with it make the process even stronger for several websites and devices. 

  1. Helps to analyze the behavior of the device

Compatibility Testing methods help in understanding the compatibility and acceptance of applications on multiple devices.

Compatibility testing ensures that the application can fulfill the expectations concerned with various models and devices.

This is a vital test to ensure that our applications work well on different operating systems, browsers, and hardware configurations.

  1. Error-Free software for users

Debugging and testing of an app for its different aspects, devices, operating systems, and browsers are required before the launch to eliminate all sorts of errors.

Furthermore, with the elimination of errors, users can easily use it according to the way they want.

Furthermore, this helps them in enhancing their business further as well as prevents downtime of their workforce. It also ensures them against hidden bugs on which they may rely during the final stage.

  1. To understand the security features of the software

Compatibility testing is the solution where people, machines, and software all peacefully coexist together.

It is a must if you are working on a product that will have various users with very different needs, be it, Windows computers or Android smartphones, etc.

A massive number of combinations are there to test. One mistake can ruin everything. Moreover, it helps the users to understand the security features that will come with it. 

  1. To check the availability of the software on other devices

The main objective of compatibility testing is to check the application for proper performance under all possible conditions.

As well as it can check whether the software is reliable enough or not which could cause a serious problem later on.

Compatibility testing should be carried out under different categories of hardware, operating system, and network environments or scenarios that are most likely to be encountered during the actual application use.

Types of Compatibility Testing

Compatibility testing is one of the most crucial parts of quality assurance. Typically, this involves making sure your software or website still functions properly on different browsers and operating systems.

If a developer works on his/her machine, you should go over the program or site in several different environments to make sure everything runs smoothly.

You may have different kinds of compatibility issues depending on what you are testing – backward compatibility being correctly running on older versions of programs and technology while forward compatibility being compatibility with future tech as well.

  1. Backward Compatibility Testing

If you want your app to reach the largest number of devices, then you should make it backward compatible.

It is important that any new app works on all devices at all times in order to allow the customer to use it confidently.

If your app is not compatible with older versions, there’s a risk that users may still be using old software or hardware and be disappointed when they can’t use your app.

The backward compatibility concept has always been critical for the software market. The software developers and companies wanted to ensure that the applications could be used with older versions of software or hardware.

  1. Forward Compatibility Testing

Forward compatibility testing is a strategy used to determine the upcoming differences in the new version of the software. It is essential that the issues raised and solved need to be compatible in the newest edition of the software.

When a company wants to innovate and introduce newer techniques, it might lead to breakdowns upon using previous versions.

Hence, it is a significant element for many companies to test forward compatibility so that the app gets integrated with future devices.

Furthermore, It is critical for consumers to have access to products and services that do not cause any hindrance in their diverse devices of use.

Bugs present in Compatibility Testing

When it comes to critiquing a finished product, there are two things that are very important to note.

First, if you want to be a good game tester, you must be able to break down the game and analyze it to see what makes it tick.

If a bug occurs only in one platform, but not in another, then you could say that this would be called compatibility testing. 

  • Furthermore, with the bugs attached to compatibility testing, it is important for the testers to understand how to remove them. Bugs can cause very serious issues. Sometimes the bugs are free to enter our systems and clog up the holes in your servers, which causes issues for your business. 
  • They prevent a system from working as intended. At other times, they communicate with other software systems present in your network and cause chaos. They can cause a system to crash or slow down drastically.
  • Software bugs are mostly ineffective when dealing with a desktop application. They tend to appear more on smart devices like tablets and phones which come into much more daily use than desktops do. But when it comes to mobile development platforms, the number of errors that can enter your system through apps becomes extremely high. 

Even using a tablet or phone doesn’t mean that you don’t need any maintenance of your operating system because the device is made up of several pieces of software with many interacting components within it.

  1. Not working on several platforms

Frequently you might find that a function that works perfectly in one platform, might not be working in another and vice versa.

This typically is because of compatibility issues. One of the major reasons is that many times you might have used a special feature of a platform that the other does not support.

  1. UI related problems

The process to deal with user interface bugs is that one needs to know why the bug has occurred and how the bug may be reproduced.

One should then retrace his/her steps to find what caused the error code and re-write his/her code. One should focus on testing and whether an update must be done or not.

Furthermore, these issues happen when an application designed for one platform is used in another.

It may be a program designed to run in Windows that is used in Linux or even vice versa. However, the device compatibility testing will ensure that the issues are fixed and hence the users can easily use it. 

Wrapping Up

Software development organizations follow various software testing approaches to verify the efficiency of software.

Compatibility test assures that the developed software product is in compliance with emerging industry standards, and easily used by clients across different platforms.

Moreover, testing the software prior to its release ensures that the product is delivered error-free. Compatibility testing verifies if the application works well with the given operating system, web browsers, and even mobile devices.

Compatibility testing is performed by checking if it contains incompatible codes or not. It also helps solve the problems of a software application during its development cycle.

This test technique ensures that the application is apt to be used on different platforms and in varying operating systems.

There are several compatibility testing methods that can be performed at different stages of the software engineering lifecycle.

The method adopted by a company depends on their needs or the applications developed by them. You can also sign up with LambdaTest for all your testing requirements.
