COMPATIBILITY TESTING (CT)

Testing the functionality of an application in different software and hardware environment is called Compatibility testing.

Compatibility Testing is a type of Non-functional testing

Types Of Software Compatibility Testing

• Browser compatibility testing
• Hardware
• Networks
• Mobile Devices
• Operating System
• Versions

Browser: It checks the compatibility of your website with different browsers like Firefox, Google Chrome, Internet Explorer etc.

Hardware: It checks software to be compatible with different hardware configurations

Network

It is to check the application in a different network like 3G, WIFI, etc.

Mobile Devices

It is to check if the application is compatible with mobile devices and their platforms like android, iOS, windows, etc.

Operating Systems

It is to check if the application is compatible with different Operating Systems like Windows, Linux, Mac, etc.

Versions

It is important to test software applications in different versions of the software. There are two different types of version inspection.

Backward Compatibility Testing– Testing of the application or software in old or previous versions. It is also known as downward compatible.

Forward Compatibility Testing– Testing of the application or software in new or upcoming versions. It is also known as forward compatible

Hardware Compatibility Test

·         Test on different processors,

·         Test on different RAM

·         Test on different Motherboard

·         Test on different VGA cards

In Test on different processors – we test for make – Intel, AMD processor and also test for speed – 3.1GHz, 2.7GHz

In Test on different RAM –we test for make – Samsung, Transient and also test for size – 1GB, 2GB

In Test on different Motherboard – we test for make

In Test on different VGA cards – we test for make – Nvidia, ATI

H/w compatibility test is not done for Web applications – because all programs run on the server and not on the local computers. We do h/w CT only for stand-alone applications

The various Compatibility bugs are,

·         Scattered content

·         Alignment issues

·         Broken frames

·         Change in look and feel of the application

·         Object overlapping

·         Change in font size, style and color

·         Object overlapping
