A programmer should not only write program code, but also be able to test it for functionality. Many people think that testing is a fairly simple process, but in reality it is not.
In this article, we will analyze what testing is. How it works, what types of testing there are, and what it is usually confused with. If you already have skills in testing program code, the information will be even more relevant for you.

Unit testing
Test-Driven Programming
The main goal of unit testing is to write tests and check the smallest unit of code. In most OOP languages, such a unit is a class. Tests are written in the same programming language as the iran email list application code. They are created specifically to check this code.
A unit test is code that checks other code for correctness. Covering code that has already been written with tests helps ensure its correctness, although it is not a perfect solution.
The most effective approach to writing high-quality code through unit tests is TDD (test-driven development).
TDD is a software development technique based on repeating very short development cycles. First, a test is written that covers the desired change, then the code that will allow the test to pass. Finally, the new code is refactored to the appropriate standards.
Unit testing is not like a test also because it lacks execution steps and does not show whether the software is working correctly. When writing a test, you can see whether the code performs the required function. If not, you have to change it until the test passes.
