Software Integration Testing is a kind of process which involves testing some particular modules where a contribution is made by two or more applications as an entire unit or other applications’ modules. This kind of testing ensures whether the applications have the capability of functioning smoothly through assimilation as well as communication established by each other. The testing comes in two different categories – black box and white box – where either is used depending specifically on the contribution level provided by other applications that are involved.
There are generally four types of Integration Testing –
- Big Bang Approach – Testing is done through coupling.
- Bottom-Up Approach – Testing is done in the method of low to high levels.
- Top-Down Approach – Testing is done from higher to lower levels.
- Hybrid Approach – Bottom-Up and Top-Down Approaches are combined.
Advantages of Using Software Integration Testing
People working in the IT industries are aware of the consistent changes which frequently occur. Developing a complex software system requires Software Integration Testing along with its required approaches.
