Benefits of Software Testing

Tuesday, 08 November, 2016

In today’s business world, software is everywhere. In the whole process of software development, testing is a phase that is often forgotten. Everybody assumes that once the software is developed, it will work flawlessly. However, it often happens not to be so. Moreover, when it does not, we are all unsatisfied and frustrated.

Problems with software are a frequent occurrence, but only a few people address them in their product. By acknowledging the importance of software testing and making it one of the early steps in the implementation process, the software will be efficient and error-free. The average project has several weeks of testing before release, and often it gets cut out entirely. That should not be so because software testing has come to play a vital role in the success of business. To raise understanding of its purpose, we will discuss the definition of software testing, about Software Development Life Cycle and benefits of software testing.

What is Software Testing?

Software testing is a series of processes aimed at investigation and evaluation of the quality of software. It ensures that software product is made by regulatory, technical, business, functional and user requirements. Software testing is a wide process that is composed of several connected processes. Through these processes are three things checked: software completeness regarding functional requirements; finding technical errors and ensuring the software is bug-free; assessing usability, performance, security, localization, compatibility, and installation. The software can be tested as a whole, in components, or within a live system. For a product to be considered fit for use, it needs to pass each of the tests. After each series of testing, the software is sent for corrections. After resolving these errors, the testing team runs the next series of tests to confirm that the errors are solved. After that, a new test series is run to identify new errors. This cycle continues until the product reaches a desired level of quality. Software Quality Assurance uses a variety of testing approaches, like unit testing, integration testing, functional testing, system testing, regression testing, load testing, stress testing, usability testing, and acceptance testing. Software testing can either be done manually or by using automated tools. Some of the methods include white box testing, black box testing, and grey box testing.

Why is Software Testing Important?

In software development, everything needs to be double-checked before the product is released. It is important to have a tester team who will test software and invest effort and knowledge to make sure that our product is defect-free.

Software testing is required to point out the errors that occur during the development phases. It assures that the application has an adequate performance and that customers are satisfied with it. When the delivered product is of quality, it helps in gaining the confidence of the customers. Software testing with strict test execution assures lower maintenance cost. There cannot be any failures because it can be very expensive in the later stages of the development. For staying in business, having a software testing is imperative. A critical defect left undetected can cause losses in business. Every serious company will invest in a tester team and find experts who will be capable of detecting problems and flaws in a software product.
Requirements Gathering/Analysis is the step critical to the success of the project.  All the needs to have to be presented in detail, and everything has to be well documented. In this phase, communication between all stakeholders, project team, and end users is crucial.  In the Design phase, lead development prepares technical requirements that will detail database tables, new transactions, security processes, hardware, and system requirements. The Business Requirement defines how the application will be written. In the Coding phase, the development team codes and tests processes applying unit testing. It is important that developers are flexible if any changes are introduced since it is the longest phase of Software Development Life Cycle. When the product is done, it is released to the Testing phase. When the application gets to the testing phase, it can be put under different types of testing. User acceptance testing is the last part of testing. Here, end users do the testing to make sure that the system meets their expectations. When all the phases are finished, and there are no errors, impleme
ntation and deployment can begin. Once when customers start using the application, the real problems will occur, and they need to be fixed on time. This is when Maintenance phase begins.

Top 5 Benefits of Software Testing

For testing experts, it was difficult to explain that the testing phase of every project is vital. Managers often see this process as a cost, and not a profit source. They want to reduce this cost by reducing the quality of the testing or with not implementing it at all. Because, their goal is to make the most profitable software possible, not so much the best software possible. An often thought is that testing does not contribute to accumulating revenue. But, that is wrong. Software testing is a great tool for business optimisation. Benefits of software testing are enormous, and they have a significant role in entire business.

First of all, thequality of your product is high, and that is important for the customer. For quality, customers will surely pay more money. Even more important is that with selling high-quality products, you build a strong reputation and brand image, things that are important in the long-term.

In the centre of every business has to be a satisfied and a happy customer. When selling something, you are aware that everything does not end there. The client can ask for a refund if the product does not suit him. If the product is not reliable, you need to invest more money in fixing or replacing it, and then you realise that it would be best that quali
ty was controlled from the start. Adding this cost, the only conclusion is that it pays to produce a higher quality product. Only when you do the software testing right can you guarantee that your product is valuable and reliable.

Speaking of profit, the testing phase is a part of it. A good product needs less promotion because people will recommend it one to another. Word-of-mouth recommendation is the best and most valuable commercial you can get, and it’s the best advertising tool. Offering a rigorously tested and quality checked product means having respect for your clients. That will help in retaining old customers and gaining new ones.

Not only will the testing phase bring profit, but it will cut down existing expenses. In the long run, it will save money because you are selling software that does not need constant fixing. It is often seen that compromising on quality ends up with having to spend more money than planned. Secondly, the benefit of software testing is that it allows removing errors and bugs before the products get shipped to the market. That will prevent unsatisfied clients and unnecessary expenses that bring customer support. Third, the costs of the service can be reduced by using automated software testing solutions.

User experience is a significant factor when putting some products on the market. Software needs to be simple, understandable, and easy to use. Only testers can assure that. Their experience will make sure that the software is designed in a way that is logical and intuitive. If you want great user experience, software needs to be free from bugs and errors, which can be a source of dissatisfaction for users. Choosing a good software testing service with a professional team will guarantee the quality of a product and good user experience.

The biggest benefit is that software testing leads to business optimisation. Business optimisation means more satisfied clients, customer retention, fewer costs of fixing a product, fewer costs of a customer service, better quality, and more reliable products, improved reputation and brand image.

Conclusion

Software testing is a set of activities that checks if the actual results match the expected results and a process that ensures whether a software system is an error-free one. But, companies and leaders do not always recognize it’s importance. The truth is, the primary goal is to release a product that will bring more profit, and the testing phase doesn’t seem to contribute to this. But, software testing is a significant and important part of software development and Software Development Life Cycle. It can be of great use when it is done from start to enhance the efficiency of the products while keeping the user in mind. Software testing is beneficial because it increases the return on investment with higher percentages. Testing will ensure higher standards in development and in delivered products which will lead to maintaining old customers and bringing in new ones.

Although it is sometimes difficult to see the importance of testing, it shouldn’t be measured purely in cost and time, rather in the great value it brings.
