Software Unit Testing: What Is It? Why Is It Important?
It is hard to overestimate the importance of software quality. A single error can have a huge negative impact on your entire business. If bug issues are not addressed efficiently, it may result in everything from an endless cycle of fixes to a destroyed reputation of your company. Effective testing strategies help to minimize such risks by ensuring the quality of the released product. There are many testing practices you can choose to build a great software solution. One of the basic but effective testing techniques to make sure that your product works properly is called unit testing.
What Is Unit Testing and What Are the Unit Testing Frameworks?
Unit testing (sometimes called module testing or component testing) is a technique for testing the smallest testable component of your code (unit) to ensure that it performs as intended. The basic feature of unit testing is the isolation – a unit test only performs a specific function and excludes all external influences, such as dependencies between units, calls to other functions, etc The unit testing process can be done manually, but developers usually use unit testing tools to facilitate the process, so they can focus on more complex tasks such as defining the test cases.
