Integration Testing and Its Types

What is Integration Testing?

Integration testing plays a critical role in software development and testing. Integration testing is a part of functional testing in which we check the functionality of integrated modules. In this type of testing, we integrate one or more than one module and then we test the integrated modules together. Software developers at Oodles Technologies provide Quality assurance solutions to enable businesses to receive highly functional apps that allow seamless navigation. 

At the time of the development phase, most of the features are coded separately and periodically and then they get integrated. But nowadays we also found the continuous integrated development helps in preventing integration-related issues.

In simple words, if we define the integration testing is combining the modules and testing the flow of data between them.

Integration Testing is divided into 2 types.

• Incremental Integration Testing:

In this, we integrate the unit modules and then we check the data flow between the modules after integrating them. 

This is further divided into two types of approach

• Top-Down Approach
• Bottom-Up approach.

Top-down approach:-

Data flow is from top to bottom, the child module is added incrementally. In his child is directly under the parent in this child follows the parent sequence.

Bottom-Up approach:-

It is the reverse of the top-down approach, bottom level units are tested first and upper-level units step by step after that

• Non-Incremental Integration Testing:?-

It is also called as Big Bang Method. In this approach modules are added simultaneously, it is difficult to find the particular issue happening in the application.

• Sandwich Approach:-

It is the combination of both top-down and bottom-up approaches.

Advantages of Integration testing:-

• Uncover the issues which occur after the integration of modules.
• It reassures the assumptions made on the unit testing are correct or not.
• To verify the software is working as it is working in unity?
• The application is tested to check or verify if the standards set by the client meets or not.
