The practice of evaluating a software application’s interface as an entire system by combining several modules, applications, or components is known as integration testing. The second step in the software testing procedure is integration testing. It occurs immediately following unit testing and prior to system testing. To put it simply, integration testing demonstrates to the testers how well different components interact. The integration testing tools help streamline and enhance the software development process.
An integration test also confirms the fact that the various components are correctly communicating with one another. Integration testing verifies that various technologies and applications are interacting as planned. Its primary goal is to assess software and module interfaces and find any potential communication problems among the two.
Here are some different types of integration testing:
Incremental Testing: This is the testing of multiple modules following their logical combination. The primary benefit of incremental testing is that by carefully examining applications that are integrated step-by-step, testers may identify issues early on. Additional categories for incremental testing include:
Bottom-Up Testing: This kind of testing begins with the architecture’s lowest level module. From the bottom of the structure, control moves up towards the top. Bugs can be immediately rectified because they can be implemented earlier stages. Stated differently, a lesser amount of time has to be spent on identification and troubleshooting.
Top-Down Testing: The top module is tested first in a top-down method. The testing control moves from the top to the bottom. Using the control flow of the architectural framework, modules are tested top to bottom via integration in the top-down manner.
Sandwich Testing: This methodology, which integrates top-down and bottom-up testing techniques, is often referred to as hybrid integration testing. Here, the integration procedure starts at the intermediate layer (downwards), and evaluation is done in both directions: upwardly towards more advanced modules and downwards towards lower-level modules. Testing control incorporates the advantages of both the top-down and bottom-up methodologies and speeds up integration testing for the module’s interfaces because it flows both upwards and downwards.
Big Bang Testing: This kind of testing, which is also non-incremental, is carried out after the system has been put together with all of its components. Putting in a different context, each module undergoes testing as a single unit after being merged with the others. Smaller systems are ideal candidates for this kind of testing.

Finding and highlighting the weak parts is essential before launching the final version. If these mistakes go unnoticed in the beginning or development stage, they will be expensive to fix when the product is out into the world. Exceptions are unanticipated circumstances or incidents that interfere with regular operations. Several things, including incorrect input from users, hardware malfunctions, or software defects, might result in exceptions. When multiple software modules or components are connected jointly, integration testing assists in resolving exceptions.
A crucial part of software development is integration testing, which verifies that all the parts function effectively to provide a dependable and strong program.
