Performing Functional Testing in Cloud environment is not too different from that in regular test environments. However, for cloud environments, the test cases need to be rewritten in order to keep them Cloud ready. Unless new features have been added as a part of the cloud hosting strategy, there is no difference in business process validation.
Functional Testing is generally performed to ensure that the services provided by the software are consistent with its specifications. Functional Testing can be performed through two perspectives –
- Requirement based testing: In this approach the requirements are first prioritized and then the tests are prioritized accordingly. This is done to ensure that the most critical tests are covered in the process.
- Business process based testing: In this approach, the testing scenarios involved in the day to day business of the system are described.
Functional Testing in a Cloud environment involves testing of all the features and functions of the system, which includes both the hardware and the software of the system. It is generally conducted on a completely integrated software platform in order to check its compliance with the requirements. In the cloud environment, the process of verification is carried out against a system of specifications and requirements on a Cloud instead of an on-premise software testing platform. Functional Testing may take various forms in a Cloud environment.
- System Testing: This testing is performed in order to test the behavior of the system within its own boundaries. It is critical to prove that the system functions as it has been designed, inputs and outputs are as expected and the overall quality is ensured.
- Integration Testing: Integration testing verifies that the Cloud environment will not be detrimental to the existing system and will successfully work with the current infrastructure and the environment.
