Samþættingaprófun

Samþættingaprófun is an Icelandic term that translates to integration testing in English. It refers to a level of software testing where individual software modules are combined and tested as a group. This type of testing is performed after unit testing and before system testing. The primary goal of integration testing is to expose defects in the interfaces and interactions between integrated components or systems.

There are several approaches to integration testing, including the big bang approach, top-down approach, bottom-up approach, and sandwich testing. The big bang approach involves integrating all modules at once and then testing the integrated system. Top-down integration testing starts with the top-level modules and integrates lower-level modules one by one. Conversely, bottom-up integration testing begins with the lowest-level modules and gradually integrates higher-level ones. Sandwich testing combines both top-down and bottom-up approaches.

The objective of samþættingaprófun is to verify that the combined components function as expected, identifying any issues that arise from their interaction. This process helps ensure that the data and control flow between different parts of the software are correct and that the system as a whole meets its specified requirements. Effective integration testing can significantly reduce the risk of errors in later stages of development and improve the overall quality of the software product.
