The term software testing is used to describe the process of verifying that a computer program functions as intended, usually through the use of test cases. There are many different types of tests that can be performed to find bugs, regressions, security issues and other problems. There are two basic types of testing; functional testing and non-functional testing. Functional testing verifies that the output from the application matches its expected result. Non-functional testing checks for errors or defects in the design of the application. Both types of testing require a range of skills depending on the type of testing being done.

Why is Testing important in Software Development?

To understand what your product does

 Most software developers have no idea how their code works. Sometimes they don’t even know how their own programs work! So if they’re not testing their code, then they can’t tell what it’s supposed to do. A good developer should always test his/her code before releasing it into production. This way, bugs are caught early and the cost of fixing them is minimized.

To improve quality

There’s nothing worse than launching a great new feature only to find out later that someone broke something in the back end. If you want to make sure that you build a product that people love, you have to test it properly.

To create better designs

 You might think that designing a website is easy. But really it takes a lot of time, effort, and skill to design a successful site. And without testing, you won’t know whether your design is working or not. You could spend hours creating a beautiful layout but if the content doesn’t load, users won’t see anything.

Test Coverage

A good test coverage is imperative in software development. This can help prevent bugs from creeping into your code base. A lack of test coverage can lead to faulty code that may cause errors or worse yet, security holes.


 Refactoring is a way to improve the quality of code through the elimination of unnecessary work, especially when refactoring is done properly and thoroughly. By doing this, we can avoid many problems down the road.

Unit Tests

Unit tests are written using unit testing frameworks such as JUnit. They provide us with confidence that our code works correctly. Without them, we would have no assurance that what we wrote actually works.

Apart from these

Quality assurance is often overlooked in software development projects. If quality control is not put into place from the beginning, then problems can occur later down the road. To prevent problems like this, it is always best to have testing done before actual coding begins. This will ensure that the project runs smoothly right off the bat without any issues.

When developing user interfaces, it’s easy to focus only on the design aspect. However, if the interface does not work properly, users may not understand how to use the application. By having testing performed after the application has been coded, developers can find out what their users are experiencing while using the application.

Test cases should be written early on in the development cycle. There are many different ways to write test cases, but they all serve the same purpose — to verify whether or not the program functions correctly. Developers who take the time to write test cases and run them throughout the entire development phase will catch bugs earlier than those who do not.

Another benefit of writing test cases early on in the development process is that it forces designers to think about the end product. Test cases help developers know exactly what the finished product should look like. They also provide a clear picture of how the interface works.

Lastly, testing allows testers to give feedback to the developer team. Testers can suggest changes to the code or even report bugs that were not caught during code review.


The conclusion from this article was that testing is not only necessary but beneficial. This is because it helps to find problems early on in the project and prevents them from becoming major issues later on down the line. Also, the sooner bugs are found, the cheaper they are to fix.
