Overview and Features of Compatibility Testing

Compatibility testing is performed to ensure compatibility of an application or Web site with different browsers, operating systems, and hardware platforms. Compatibility testing is one of the several types of software testing performed on a system that is built based on certain criteria and which has to perform specific functionality in an already existing setup/environment.

- Compatibility testing can be performed manually or can be driven by an automated functional or regression test suite.
- The customer has different kinds of platforms, operating systems, browsers, databases, servers, clients, and hardware.
- Different versions, configurations, display resolutions, and Internet connect speeds all can impact the behavior of your product and introduce costly and embarrassing bugs.
Therefore, compatibility testing becomes necessary.
- Software is rigorously tested to ensure compatibility with all the operating systems, software applications and hardware you support.
- Compatibility testing will ensure that the code is stable in both environments and that any information/error messages or user interaction is handled and presented in the same way regardless of the OS.
- Compatibility testing can be easily accommodated in manual tests by having different members of the team work on varying screen resolutions to see what issues arise.
- Compatibility testing should take account of the varying connection speeds available to the user base.
- Compatibility testing may be undertaken as part of Performance Testing and so it is always worth checking out what the non-functional test team on a given project are planning to run in order to see if this is covered.
- Compatibility testing can be used to evaluate the performance of system/application/website on network with varying parameters such as bandwidth, variance in capacity and operating speed of underlying hardware etc.
- Compatibility testing can be used to evaluate the performance of system/application in connection with various systems/peripheral devices.
- Database compatibility testing is used to evaluate an application/system’s performance in connection to the database it will interact with.
