Unit testing is the first phase of the Software Testing Life Cycle (STLC) process, where the smallest piece of code known as units or individual components is tested. This testing method is performed to make sure that all the individual units or components are working in accordance with the expected requirements. A unit can be a method, function, subroutine etc. The correctness of the code is identified and bugs are detected at the earliest and fixed, which in turn helps in saving time and cost. Through unit testing, the codebase can be easily understood by the testers, thus enabling them to make quick changes. In this article, you will get to know about the purpose of unit testing. Following are the five reasons that justify the purpose of unit testing: 1. Unit testing plays a pivotal role in Extreme Programming (XP): Unit testing is a key part of extreme programming methodology. Incorporating unit tests with XP makes development and code refactoring simpler, develops documentation and makes integration easier. 2. Reliable and reusable: In a unit test environment, the product’s individual modules become isolated from one another and have a specific responsibility. This means that the code is reliable, and because in a tested environment, it has also been tested hence, it is reusable. Reusable code is considered to be consistent, efficient and clean. 3. Documenting Effectively: Unit tests provide a platform for effective documentation. In order to know the functionality provided by one module to another, unit tests can be referred by developers, so that a basic idea about the logic of the module and the system as a whole can be obtained. Indicators are represented by unit test cases that provide information about inappropriate or appropriate use of a software component. In-depth documentation for these indicators is provided by these cases. 4. Quick and easy identification of bugs: The tests covered with code are more reliable than the tests covered without code. If any issue arises in the code due to changes being made to the code, then the root of the problem will be identified by the developer right away.
According to best practices, a group of tests or all unit tests should be first run by developers locally, in order to make sure that the existing code is not disrupted by coding changes. In a specific scenario, after making changes, a developer might forget to run unit tests, due to which potentially non-working code is submitted to a common branch. In order to avoid this, a continuous development approach is applied by companies. Continuous integration tools can be used, which, in turn, allows developers to run unit tests automatically. The tools that are being used for continuous integration determine the speed at which non-working code is detected. 5. Enhanced code coverage: Test coverage ensures that the code should be covered in its entirety. There are many tools that can be used when unit tests are written, in order to ascertain the total percentage of project coverage, function or a separate module. The code sections covered by tests are graphically displayed by these tools and the sections in the code are indicated for which unit tests can be written. When a code is being written, it is important to know whether a particular line can be executed or it can be eliminated. When valid unit tests are available, then coverage metrics can be used to determine whether a code line is relevant or not. Conclusion: If you are looking forward to implementing unit testing for your specific software development project, then do get connected with a premium software testing services company that will provide you with a viable testing strategy that is in line with your project specific requirements.

Architectural plans are detailed, scaled drawings that outline the design and layout of a building or structure. They encompass floor plans, elevations, sections, and other essential details, serving as a visual guide for construction teams. These plans convey dimensions, materials, and spatial relationships. Architects utilize specialized software to create precise plans, ensuring compliance with building codes and regulations. They are crucial documents in the construction process, providing a blueprint for realizing architectural visions.
