Importance of software testing on software development life cycle

software testing life cycle


One of the biggest challenges in creating good software is the testing phase. Software development lifecycle has evolved drastically over the years, but have we adapted to the evolving nature of software testing?

Pretty good testing is easy to do (that’s partly why some people like to say ‘testing is dead’– they think testing isn’t needed as a special focus because they note that anyone can find at least some bugs some of the time). Excellent testing is quite hard to do, says James Bach, a renowned software tester.

Bach is known for challenging himself and others to create great software through clever testing during the software development life cycle. He believes that every developer can’t test, because it is something which requires a mix of critical thinking, analytical and social skills. If software testing is not performed systematically, then it is just checking.

When testing is part of the software development life cycle in the early phases, bugs and other errors can be picked up and reported at the earliest. Not to mention, the cost of fixing bugs increases with the complexity of the software and how later they’re found in the developmental phase.

Mentioned ahead are some more benefits of implementing software testing during the development life cycle of your software:

Quality check

Be a yardstick of quality. Some people aren’t used to an environment where excellence is expected.”— Steve Jobs

In the highly competitive software industry of today, quality plays an important role. That’s why, a software test plays a key role in the development life cycle by actively keeping a check on the performance and quality of the software. Testing will ensure that the software is error-free.

Any defects can be identified immediately and fixed. Automated testing makes the situation easier by running in the background while engineers focus on other important tasks. The repetitive nature of these tests is handled effectively through an automated testing tool. According to Accelq:

Just like when you design and architect your application, you don’t take a numbers approach; planning your quality focus should be on Test Design. Adapt a test design which is driven by your application business processes, and which encapsulates both the application workflow as well as data combinations. A design that comprehensively covers modularity, reusability and that seamlessly links to your requirements and user stories.

Automated testing improves consistency and performance of the software development lifecycle. Moreover, the stages of testing play an important part in fault recognition. When you launch a finished software and it is bug-free, you are acting upon the direction of the testing tool which showed you estimated outcomes so you could improve the actual outcomes which increase the quality of the product.

Saving the user

Software can be dangerous to the end user if it is not properly tested. Users will be confused, frustrated and might never use the software again if they face errors in the very first run. A solid automated testing tool ensures there are no errors at the user’s end and the security is tightened before the software even makes it to the market. It helps in authenticating and validating key elements through several testing phases.

Your software can be defect-free and its configuration will also be checked periodically by a good testing tool. Incorporating this process in your software development lifecycle means that you have successfully saved hundreds of users from falling victim to a security glitch which isn’t their fault.

Perhaps, the best and latest example of this fallacy is the WannaCry attack which affected a global segment of users of Windows operating system. 98 per cent of the computers affected by the ransomware attack were using Windows 7.

It brought to light the weakness in Microsoft’s patching practices and updates to the newest operating systems. Financial institutions and other major organizations all over the world faced huge losses simply due to a bug which was released through a weakness in one of the most popular operating systems in the world.

Reliability testing

This is yet another benefit of testing during the software development lifecycle. The reliability of your software is determined during the development phase. If the software has gone through smallest levels of unit testing and major levels of regression testing during development, then it is a reliable one to use and pass on to the market.

If someone claims that the software was faulty from the beginning, you have a decent collection of data to negate those false claims. It secures your investment and further improves the credibility of your company. No wonder it is one of the best statistical methods that defines operational testing, which results in a reliable and durable software product.

Economic importance

A well-tested software will be good for your company for its strong economic impact. Any user will trust your company with software and will stick to your software because of the benefits. Testing during the development lifecycle saves your company from updates and other budget-related issues which arise if a defective software is released in the market.

You and your team will also be confident of the end product because it will go through several unit tests, user interface tests and regression tests until the last check is complete.

Testing is more important than you think…

Most developers and stakeholders argue over the interference of a software testing tool in their development life cycle. Many believe it disrupts the development process. If you look at the stats, Up to 50% of mobile users report that they’ll immediately delete an app if they spot a single bug. The stats for web products are nearly the same.

You can’t afford losing all your customers and the reputation of your company by pushing forward something defective. In the case of WannaCry, Microsoft came under huge criticism but it could defend itself thanks to its decades of software innovation. If you are a startup which is coming up with their very first software, users and critics might not spare you a second chance.

So, why should you implement software testing during the development life cycle? Because:

• It improves the quality of your software

• It prevents the user from using a software with bugs

• It increases the reliability of your software

• It saves you money

• It saves your company’s credibility
