Egységtesztek

Egységtesztek, often translated as unit tests, are a fundamental practice in software development. They involve testing individual components or units of code in isolation to verify that they function as expected. A unit is typically the smallest testable part of an application, such as a function, method, or class. The primary goal of unit testing is to catch bugs early in the development cycle, making them cheaper and easier to fix.

The process of writing and running unit tests is typically automated. Developers write test cases that define specific inputs and expected outputs for a given unit of code. These tests are then executed, and if the actual output matches the expected output, the test passes. If there's a discrepancy, the test fails, indicating a potential bug in the code. This feedback loop allows developers to refactor or modify their code with confidence, knowing that existing functionality remains intact.

Unit tests play a crucial role in maintaining code quality and stability. They serve as a form of living documentation, illustrating how specific pieces of code are intended to be used. Furthermore, a comprehensive suite of unit tests can significantly reduce the time and effort required for integration and system testing, as many issues are identified and resolved at the unit level. This practice is a cornerstone of agile development methodologies and contributes to the overall robustness and maintainability of software projects.
