Why manual testing is still crucial for software quality?

Although advancements in technology have aced the development of automated testing software, manual QA testers need not fear. Yes, there are benefits of automated software that manual testing cannot provide. However, the same concerns certain aspects of manual software testing. Across the realm of different testing types, it becomes clear that manual one is as important as it used to be, and will continue to be prominent for years to come. Here are just seven of the many reasons why manual testing is still a critical part of the software quality.

Reason 1: Manual Testing Resources

Sure, sometimes the time required for manual testing pales in comparison to the time spent on automated software tests. Moreover, these types of tests tend not to be administered until the end of the software development process. That means errors that could’ve been caught earlier are often skipped until the eleventh hour. 

With manual software testing, QA engineers execute different types of tools throughout the process, as there’s minimal front-end work involved. Manual QA engineers run a variety of tests while developers work on the product simultaneously, resulting in saved time, money, and resources for all parties. 

Reason 2: Manual Testing Has the Same Error Rate as Automated Testing

While you might believe that automated testing is the holy grail for error-free testing, it’s not. Any test may result in errors. Since automated testing is essentially a piece of code, there are still chances errors occur and automated test script fails. With manual software testing, QA specialists are more prone to human errors. But the benefit of manual software testing is the opportunity to check the software from a user’s perspective, which is a crucial part of the overall business strategy. 


Reason 3: Improved UI and User Experience

 Remember when you left the website for the images weren`t uploaded or the font was unreadable? Well, these guys needed a tester for their GUI unless they wanted to lose their customers.  Manual testing provides constant reviewing of the site or application by professionals to keep it accessible for different devices, user-friendly, and interface bug-free. These experts can easily identify reasons that negatively affect performance and usability.

          

Reason 4: You Can’t Replace People 

Some testing types are just impossible to automate. Their essence lays in checking by a human being, by a user. They include API, UX, UI, and exploratory tests. Graphical interface, adaptive design, random tests - they`re all about human involvement. 


Reason 5: Manual Testing is Cost-effective for Short-term

Some argue that automated testing ends up being more cost-effective than manual. However, automation will surely take years. Upfront and in the short-term, manual testing is surely more affordable nowadays. Consider the amount of time, technology, and resources required for automated tests. The actual cost of building and running automated testing framework ranges from 5 to 15 times as much as the cost of manual testing. Opting for the latter will help you see results sooner and save money. 


Reason 6: Manual Testing Allows to Perform Exploratory Testing

With manual software testing, QA engineers have the freedom to conduct any tests. With automated testing, they can’t fully interact with the software. People are spontaneous and their behavior is what machines can`t predict. If you know you’ve hired that skilfull staff, make sure to instruct them to demonstrate their experience by handling exploratory testing.

Reason 7: Manual QAs Apply Critical Thought

With automated testing, the result is a list of problems - you’re expected to involve different departments of the team for solving them. On the other side, a manual tester keeps in mind the client’s requirements. Moreover, their previous experience helps find a solution for frequently occurred problems according to the needs. Sometimes, the concept could be altered during the development process, and a human is able to adapt.


Conclusion

While using automated testing methods is efficient and cost-effective in the long-term, the importance and efficacy of manual software testing shouldn’t be overlooked. This article explored seven of the many ways that explain why manual testing is critical for software quality. By understanding the strengths of each type of testing and using a collaborative approach between the two, you can rest assured that your software application is running as smoothly as possible.
