Who Performs Unit Testing?
1. Developer
Developers are the ones who are responsible for unit testing to determine if the particular method or function works or not.
- With unit testing, we can identify issues with the specific method or function and develop the respective features accordingly.
- Regarding Unit testing, the developer has a huge responsibility because they are the ones who are taking the first step towards a better quality of an application, also it is like a self-review tool for them before pushing it for code review and deployment to the test environment.
Benefits of Developers Testing Their Code
- This leads to a better understanding of code design because when they write tests, they think about design in smaller testable chunks.
- Speeds up the debugging process by detecting errors or bugs at a very early stage of development.
- Saves time and effort.
- Helps to fix the bugs immediately based on the feedback. (That means unlimited chance of refactoring).
2. QA Engineers
Unit testing is essentially a White Box Testing technique, meaning we perform testing where we know the software works internally but only white box testing is not sufficient that’s why QA (Quality Assurance) comes into the picture.
- The role of QA engineers is to find bugs in the software that unit testing did not find. This is because QA engineers have a different view as compared to developers.
- They use black-box testing instead of white-box to verify the application’s functionality. But when unit testing is done properly before the QA engineers start their work, it brings a huge benefit to software projects. In short, the QA engineers build on the foundation that developers have laid out.
Who performs Unit Testing and why is it Necessary?
Unit Testing is an essential software development procedure that is vital to guarantee the quality and dependability of software solutions. It entails testing separate software program units or components one at a time to ensure that everyone performs as intended. Even though unit testing is a generally accepted practice, there are still questions in the software development world about who does it and why it’s important.
