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 in a smooth way 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 together.
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.
Big Bang Approach
- Convenient for small applications.
- Easy detection of faulty bugs.
