7 Essential Benefits of Unit Testing

With quick software releases and development on the rise, we need to make sure that there is no comprise on the quality. To ensure quality software developers carry out various tests to ensure the functionality of the software. Parts of the software must be running efficiently.

To determine the efficiency of individual units of source code we carry out unit testing. The smallest possible component of the software is the unit. A single unit normally has one specific function to perform.

The unit is small in size which makes its handling and designing easier. It is not difficult to record and analyze its test results. Locating bugs using unit testing and fixing them is comparatively easier.

Unit testing aims to distinguish each part of the program to see if each part is working properly on its own. Its ability to identify defects on a large scale shows us how important it as a part of software testing.

If the software is taken as a complex whole it can be harder to identify issues. Unit testing enhances the coverage and quality of the test because each unit gets individual attention. This helps in automating the testing process.

Unit testing allows you to find defects easily and in a short span of time. Stick with us to learn some in-depth benefits of Unite testing.


Filtering out the bugs

Bugs are a common issue that plagues software developers. Fixing these issues can occupy a significant amount of time and at times prove to be difficult. It’s better to identify these issues during the development period than in the production or staging period.

To check for these bugs functional testing services are done, unit testing is a type of functional testing. Making the unit test part of the work process can allow the detection of these issues early on, almost as soon as the code is written. This put the development team in a position to be able to fix these issues as soon as they surface.

Easily Change and Refactor Code

Automated unit tests make it quite easy to catch bugs, which makes you more confident in your product. A software developer feels more at ease after detecting bugs before the release of the application itself because even if hard they have a chance to fix it beforehand. It is a success to identify any issue prior to its release to production.

Test Automation

The whole purpose of testing is to be able to identify the outcomes to assure that the code will run perfectly later on. Manual testing compromises on time efficiency and quality of the software testing.

Using automated tests are quick and allow us to maintain the frequency of testing even if we have other tasks occupying us. Once the scripting of the automation test is done we can make use of it repeatedly.

Code Design

When thinking about unit testing you need to make sure that the code is testable. By breaking down larger units into small units you need to make sure that each component is testable.

Unit testing helps in making the code design more efficient by proper unit segregation, better unit interfaces and the overall concept of design.

Help in documentation

When carrying out unit testing you are providing its documentation. The unit test helps to ensure the proper performance of the software and is only sent for release when its approval is done.

Identifying the functionality of a unit through a test allows developers to conclude if the unit is working or not. It helps to be able to understand the thought behind the code. So documentation can work as a memory log to tell you why you wrote what you wrote.

Improves Teamwork

Unit testing also helps improve teamwork. It allows your peers to review the logic and thought process behind your code. This allows trust and better understanding making the team more cohesive.

Inspires Confidence

It is a whole process to ensure the legitimacy of your product. You design the software then you make tests to conduct on your software. These tests help you to validate the functionality of your software in its early stages.

Once you clear all the tests you can rest knowing your product is of quality and is running smoothly on all mediums. Having faith in your product gives you confidence as you know that customers are likely to have a great experience using your product.


Unit testing is very important because it assures functionality at a micro-level. If individual units of a function are failing to perform how will the application perform well on a larger level? To help smooth out these concerns developers turn towards unit testing.
