Why is testing Necessary?

Human errors can lead to the development of a error and/or inability during any point of the software development cycle. The consequences are classified as either trivial or catastrophic, based on the impact that results from the error. The need for strict testing and the associated documentation throughout the development process is due to the following reasons:

To identify defects
To reduce the risk of flaws within the system or component
Enhance Quality of System
There could also be an obligation to conduct testing of software in order to satisfy specific industry standards or legal requirements. These rules and standards may specify which techniques we must employ in development of the product. For instance the aviation, motor and medical industries as well as the pharmaceutical and medical industries. All have guidelines for testing their products. The following points illustrate the importance of testing an easy and reliable software product: utilize software application:

The testing is vital as it uncovers bugs and defects prior to the release to the client that ensures the high-quality of the program.

This makes the software more stable and simple for users to utilize.

The rigorously tested software guarantees the reliability and performance of software operations.

Let's say you're using a Net banking application, and you want to send the funds to the account of a friend. You initiate the transaction, you receive an error message and the transaction is deducted from your account. However, your friend informs you that his/her account hasn't received any credit until now. Also, your account is in no way reflecting the transaction that was reversed. This could cause you to be angry and make you an unhappy customer. The question is how did this occur? It's due to the inadequate testing of the online banking application prior to its. It was released. An exhaustive testing of the site for all possible user-related operations will lead to a quick identification of the issue. Thus, it is possible to fix it prior to making it available to the general public to ensure a more smooth experience. Testing's role in success In the example above it is evident that due to the existence of flaws that the system was unable to execute the needed operation and did not fulfil the specifications of the client. Properly applied testing techniques to all test levels and a high degree of testing expertise will ensure a drastic decrease in the number of these software failures.

Testing testers' involvement in review of requirements and story revision - involving testers in the requirements phase helps to identify certain requirements-related defects before they are implemented. This significantly lowers the fix cost. Furthermore, the tester will gain important insight into the project at this point. This, in turn, assists him during the implementation stage that follows the completion of the task.

Testers who work closely with system engineers can help them gain a better understanding of every element in the process. Furthermore, it assists in reducing the chance of design flaws fundamental to the design and helps to identify flaws at an early point. Furthermore, it enhances how well integration situations are designed, and will result in better quality of defect detection.

Testing testers in close collaboration with developers - When testers collaborate with developers, they improve their knowledge of every part that code. Additionally, it allows testers to perform more effective testing to meet customer demands. This reduces the chance of slippage in defects. Testers also learn about areas that are deemed to be risky by the developer and can alter their priorities in line with. In addition, developers get the insight of the tester. This assists in reproducing issues immediately without having to go through the lengthy defect management procedure.

Testers are responsible for confirming and verifying the software prior to its release. This aids in identifying errors that could have gone unnoticed and aids in getting rid of the flaws that led to the errors. Testing at various levels improves the chance that the application will be free of errors and will also satisfy the client's requirements.

Software Testing: A Critical Quality Aspect The production of a top quality software product with distinct and original features has been the top priority of the industry of software worldwide. But, without testing software components under a variety of circumstances, both expected and unanticipated The team is not able to guarantee the quality of these elements. Therefore, tests are conducted to test all software components big and small. To comprehend the importance of Software testing Lets take a look at the following points:

Testing software is vital. Therefore, don't begin from scratch We may test the software we have developed against the requirements of the user and discover that a fundamental function was not present. It could be because of an error in the requirement gathering phase or the coding process. To correct these kinds of mistakes, we might be required to begin process starting from beginning from scratch. Repairing these kinds of errors can be very time-consuming, laborious and costly. Thus, it is recommended to test the software during its development phase.

Assessing the user-friendliness of the software: Ease to use is a straightforward idea that outlines how easy the intended users will be able to utilize this final software. The testing of software ensures that the design of the product in a manner that is in line with the expectations of the user regarding the compliance requirements in a pleasant, satisfying and easy way.

Verification of every aspect of the software - You can check all aspects of the software during testing the software, including testing the fundamental functions as well as testing the system for unusual situations. Unexpected events could be due to an error in the data type or the threat of piracy. Thus, testing ensures that the system is able to handle these kinds of situations effectively. If we discover an error before we know it we can choose to rectify the issue. It is possible to prevent complaints once the application or software is available to users.

Software tests can speed up development Software tests assist developers discover errors and possible scenarios that replicate the error which then allows them fix the issue quickly. Additionally, software testers are able to collaborate together with a developer which allows them to understand the designs, risk areas and so on. in detail. This exchange of information between developers and testers accelerates the development process.


In conclusion, the significance of testing software is vital. Testing software is an essential component of developing software products as it enhances the consistency and efficiency of the product. The primary benefits of testing are detection and removal of the mistakes. Testing also assists testers and developers to evaluate the actual results and expectations to ensure quality. If software development happens in a manner that is not tested, the software might be dangerous or ineffective for users. Thus, the tester must wear a special cover that guarantees the integrity in the application and ensures it is secure to use in real-world situations.
