Integration Testing

Testbytes offers integration testing services for development teams that want to hand over integration testing tasks to an independent testing service provider. It is the phase of software testing where individual software modules are combined and tested as a group. It is done after unit testing and before the onset of validation testing. The input modules are unit tested before integration testing is done. These are then grouped into larger aggregates and further testing is done to those aggregates. The final output after this testing is delivered as an integrated system made ready for system testing.

What Integration testing Ensures?

Integration testing verifies the functional, performance, and reliability requirements of a product. In this form of testing, test cases are constructed to check the correctness of all components when they interact with each other. The idea is that of a “building block” approach, where verified components are added to a verified base on which integration testing of further assembled components is done. Some different types of integration testing are big bang, top-down, and bottom-up.

Big Bang

In this approach, a complete software system or major part of the system is formed by coupling together most of the developed modules and this is then used for integration testing. This method saves time, but if the cases and their results aren’t recorded properly, the test becomes more complicated and may lead to losing valuable time.

To be more efficient and accurate, care must be taken while defining the user-like workloads in order to create a realistic scenario of the environment. This gives confidence that the integrated environment will work as expected for the target customers.

Top-down, Bottom-up and Sandwich Testing

Bottom Up: In this form of integrated testing the lower level components are tested first and are later used to facilitate the testing of higher level components. Until the component at the top of the hierarchy is tested the process repeats itself. This approach can only be fully utilized when most of the modules in the same development level are ready.

Top Down: In this testing methodology the top integrated modules are tested followed by the step by step testing each branch of the module until the end of related modules.

Sandwich Testing: This approach combines top down testing with bottom up testing thereby inheriting the advantages of each of the testing methods. While the Bottom-Up approach helps to easily find bugs, Top-Down helps to easily find a missing branch link.
