Next on the list is integration testing, which is a key software testing type that evaluates how well the system communicates between different components or modules.
It validates that these components integrate and work together smoothly. Bottom up integration testing verifies that data flows correctly between modules, dependencies are accurately managed, and overall system functionality is not compromised.
It identifies problems such as incorrect data transfer, inconsistent interfaces, or faulty interactions that may occur during the integration process. Integration testing plays a critical role in ensuring that each part of the software system works in tandem to achieve the desired functionality. There are two main subtypes of integration testing:
This approach works best when there’s a clear relationship between software modules. Developers take two modules and verify the flow of data between them. If the integration between them works well, they can add another module and test again. In other words, we can say that developers incrementally add modules and test the data flow in the integration between them.
There are also two types of incremental testing, called top-down and bottom-up approaches, which are based on the parent-child relationship within the system. The incremental method allows early detection and resolution of integration problems and reduces the complexity of testing.
If the data flow is complex and there are difficulties in classifying parent-child relationships, developers can choose the non-incremental integration testing approach, also known as the big bang method. This method may be appropriate for smaller software projects or when all components are readily available and stable.
Example of integration testing process:
A team of developers is working on a software application that consists of a web-based front-end, a middleware data processing layer, and a back-end database. They are setting up integration tests to verify that data submitted to the front-end is properly processed by the middleware and then stored in the underlying database.
