The test is the first test to be carried out before testing integration and system testing. Unit testing is the practice of testing tiny parts of software, typically single, alone and isolated functions. With Unit Testing it has three benefits which are:
- Quality of Code
- Find Software Bugs Early
- Facilities Changes & Simplifies Integration
Quality of Code
Unit testing enhances code quality; it identifies any flaw that might have aroused before further code is sent for integration testing. Writing tests before code makes you believe the issues is more difficult. It exposes the instances of the edge and gives you better code writing.
Find Software Bugs Early
Issues are discovered early on. Because unit testing is performed by developers where they test their individual code before integration, problems can be discovered very soon and then there can be solve without affecting the other piece of code. This involves both the programmer’s application bugs and the unit’s specification faults or missing components.
Facilitates Changes & Simplifies Integration
Unit testing enables the programmer at a subsequent date to refactor code or upgrade system libraries and ensure that the module is still working properly. Unit tests detect modifications that can break a contract for design. They assist preserver and change the code. Unit Testing really decreases faults in newly developed features or decreases bugs when altering the existing functionality. Unit Testing checks each unit’s precision. With, therefore Unit Testing is suitable for website project system.
