Einingarprófanir

Einingarprófanir, or unit testing in English, is a software testing method where individual units of source code are tested to determine if they are fit for use. A unit is the smallest testable part of an application, typically a function, procedure, method, or object. The goal of unit testing is to isolate each part of the program and show that individual parts are correct.

This type of testing is performed by developers during the development process. Developers write unit tests for their code to ensure that each unit performs as expected. If a unit fails a test, it indicates a defect that needs to be fixed. Unit tests are often automated, allowing for frequent and quick execution. They can be run manually, but are commonly integrated into continuous integration and continuous delivery (CI/CD) pipelines.

The benefits of unit testing include improved code quality, easier debugging, and better design. By catching bugs early in the development cycle, unit tests reduce the cost and effort of fixing them. They also encourage modular and well-designed code, as units are more easily testable when they are independent and have clear responsibilities. Furthermore, a comprehensive suite of unit tests can serve as living documentation for the code, demonstrating how each unit is intended to be used and what its expected behavior is.
