Compatibility is the capacity to exist together. As a real-life example, water is not compatible with oil, but milk is. The same thing happens with software or apps that we build.
Compatibility testing is a crucial QA task which guarantees that the software or product that is being tested is compatible, as desired over a broad set of client frameworks and configurations.
The expansion of web browsers, OS (operating systems), and devices has forced associations to guarantee that all their products work as planned over various platforms to avoid costly bugs entering the market or production.
If we talk about ideal testing, one is expected to check the product or app on all possible platforms manually. However, in reality, there are a few limitations, like time to test, budget, and resource availability. So, different tools and devices are often used to test an app or website.
This sort of testing helps discover how well a product performs in a specific environment that incorporates network, OS (operating system), hardware, and other software. It is essentially the testing of the application or products built with the processing environment. It tests whether the application or product is working perfectly with the database, operating system, and hardware or other framework programming, or not.
Need for Compatibility Testing
While releasing a software application, you should keep in mind that it must be of high quality and compatible with all operating systems, hardware, software, etc. You can ensure this through compatibility testing. Compatibility can be guaranteed through embracing compatibility testing which checks for errors or bugs before delivering to the client. For example, mobile compatibility testing of an app or website can be done on various devices with different screen sizes and resolutions.
This testing confirms that the app meets every one of the prerequisites set and agreed upon by both the engineer and the client. This software thus enhances the reputation of the firm.
It is likewise true that quality items improve sales and advertising efforts and bring delight to the user. Besides, an effective compatibility test guarantees genuine compatibility among various processing conditions. Moreover, excellent compatibility testing services additionally affirm the stability and strength of the product that is of much significance before its release.

Types of Compatibility Testing
There are two types of compatibility testing:
- Forward Compatibility Testing: This kind of testing checks whether the product works well with the more up-to-date or upcoming renditions, and is consequently called forward compatible.
- Reverse Compatibility Testing: This kind of testing checks whether the product designed using a current version of an environment also works well in an old version, thus it is called backward compatibility testing.
Compatibility testing can be performed for the following:
Databases: Testing crosswise over databases like Oracle, SQL Server, etc.
Web Browsers: Testing crosswise over programs like IE, Chrome, Firefox, Mozilla, Safari, and so on. Some of the most common mobile cross-browser testing tools include Browserling, Browserstack, Browsershots, and Browsera.
Operating Systems: Testing crosswise over OS's like Mac OS, Linux, and Windows.
Other System Software: Testing the web server, organization, update apparatuses, and so on.
Mobile applications: Testing crosswise over various mobile platforms, devices, networks, and so forth.
Some of the most widely recognized compatibility testing defects are
- Changes for text dimensions and alignment issues,
- Issues related to the scroll bar,
- Changes in CSS style and coloring,
- Presence of broken tables or frames.
Why Do Compatibility Testing?
A badly designed software product that does not work with the majority of systems is risky for the reputation of the organization. Your profits will be reduced because you will not be able to sell this kind of product to all users. Furthermore, clients that do purchase the product and find out that it doesn't work may never buy products from your organization again.
Organizations that experience compatibility issues too late will have to try to correct the issue after the app is already released, which will lead to costly repairs. Performing compatibility tests before the app is released can enable your app to maintain a strategic distance from numerous entanglements.
So, go for it before releasing any of your products to ensure quality.
