Hi,
In any project / enhancements there will be several rounds of testing done before the changes are moved to Production client. This is basically to ensure that the proposed solution works as per the requirements of the User and at the same time it does not impact the existing settings / configuration.
Normally in any project the following cycle of testing is followed:
Unit Testing: Once the development or Configuration is completed it is tested in a client in Development box which is known as UNIT TESTING. This is to ensure that at a broad level the changes are working.
Integration Testing: In the next step the testing is done in a Test client, which is known as Integration Testing. At this level, it is checked that in depth to ensure that it is working as per the requirements in conjunction with the settings in other modules.
UAT: User Acceptance Testing is done in Quality client which is a close replica of Production environment. In this client, the end users will do the testing and confirm it is as per the design requirements. Unless UAT is completed the changes cannot be moved to Production client.
In some projects a separate regression test is also carried out to ensure that existing functionalities are not getting impacted because of the proposed changes.
Thanks
Murali.
