Moduulikattavuus

Moduulikattavuus, often translated as modular coverage, is a concept in computer science related to testing and verification. It refers to the extent to which a set of test cases covers the individual modules or components of a software system. The goal of achieving high moduulikattavuus is to ensure that each part of the software is tested thoroughly and independently.

This concept is particularly important in large and complex software projects where it is impractical to test the entire system at once. By focusing on individual modules, developers can isolate and fix bugs more efficiently. Moduulikattavuus can be measured using various metrics, such as the number of modules tested or the proportion of code within each module that has been executed by tests.

Achieving good moduulikattavuus typically involves a combination of unit testing, integration testing, and system testing. Unit tests focus on verifying the functionality of the smallest testable parts of an application, while integration tests ensure that these modules work correctly when combined. System testing then evaluates the complete and integrated software as a whole. The principle of moduulikattavuus encourages a structured approach to testing, breaking down the problem into manageable parts.
