SIT Phase

SIT Phase...?? What is it?? Is that sit? I mean we all sit on the chair or some other thing.  Few weeks i heard about this in my office but in fact I really don't know what is that. Nobody tell me about that include my team lead because everyone is busy work on it. So i need t figure out what is SIT. Hurmmm....

WHAT is SIT?

SIT or formally known as System Integration Testing is a testing on the functionality for an application. It is done to ensure that all the sub component are integrated successfully to provide expected results. SIT is one of the levels in software testing where the entire system is to be verified against the specified requirement. Usually sit done by tester or QA before the system go live.

Purpose of SIT?

1. To ensure that all modules work as specified.

2. To ensure integrated system work as per system requirement specifications (SRSs).

3. To ensure the code is ready for all type of testing scenarios either positive or negative.

SIT testing  usually done by

- System Requirement Specifications

- Business process

- Use cases

- High level descriptions of system behavior

- Interaction with the operating system (OS)

- Existing or new risks

Example:

Currently my user is a banking company. They want a new system which is meet all their requirement. So we as a vendor introduce them with our system but few screens in our system doesn't meet their requirement. So we need to do some enhancement that fulfill all the requirement. Let's say Client Details modules have 2 screen and database. Both screen require client details and all stored in one table database. Compare with the requirement, we need to enhance the module which meet all the SRSs from user. So, we develop new screens together with the database. The new screens and database are integrated with the existing screens. Then testing is done by QA Team which is called as SIT. The testing process is to ensures that all sub-components are integrated successfully to provide expected results and meet all the requirement. This process we called as System Integration Testing.
