Are You Performing QA & Software Testing Processes Rightly? Check these Myths!
Undoubtedly, the most critical part of software development process is ensuring that the final product is OK tested and assures superior quality. But, just as every field has various myths, so does the field of Software Testing & Quality Assurance. These myths have arisen primarily due to lack of knowledgeable insights, complexity of the process and misunderstood facts and logic.
Be it be any case, there’s a long list of myths and misconceptions. Following are some of the commonest ones around.
Myth #1: Complete Automation is Required to Ensure Superior Quality
Fact: It is not an undeniable fact that automated testing accelerates the overall testing efforts by reducing the need for certain repetitive manual testing scenarios, but that doesn’t mean that the need for manual testing is vanished. A system that works perfectly fine under regular inputs during automation testing, sometimes fail when a random human input is fed (ad-hoc testing). Thus, to achieve effective testing and a high-quality product, both automation and manual testing must coexist.
Myth #2: There’s no Difference in Quality Assurance and Testing
Fact: Testing is a part of quality assurance, but many people use these terms reciprocally. But Quality Assurance is a broader term and covers the entire software development life cycle right from the requirements gathering phase to the maintenance phase. It typically involves deciding on the testing standards, documentation and sign-off gates along with various testing techniques used to test the system effectiveness and efficiency.
Myth #3: Once tested, a system is bug free
Fact: Testing is basically a continuous process that never ensures the system is completely bug-free, even if all the paths and scenarios have been properly tested for. The whole idea of testing and quality assurance is to bring a system down to an acceptable level, with bugs that are otherwise known (known defects) but are left as the system is stable and doesn’t fail in any sense.
However, being an ongoing process, these bugs are fixed and checked for any side-effects on other modules as a part of the maintenance and the probability of any critical bugs left in the system comes down close to nil. Thus, it’s extremely important that every party involved understands this and agrees upon what an acceptable level of defects must be.
Myth #4: The more you test a product, the better it becomes
Fact: Accomplishing 100% test coverage by encasing all possible test scenarios is not a feasible approach to a high-quality product. In the changing development schedules, it is important that a more systematic approach is put to use in order to determine priorities based on various business essentials and the risks involved.
Myth #5: It’s only the Responsibility of Quality Assurance team to Perform Testing
Fact: It can be extremely unfair to leave quality assurance to be taken care of by a specialized team only. However, QA professionals care deeply about the quality and look at the system from a whole new perspective, but it is also important that every individual involved in the process must also take responsibility of the same so that the end product can be of high quality with near zero defects.
Myth #6: It’s OK to leave quality assurance for the end
Fact: Usually, it is believed that the testing process starts when the development phase comes to a halt, but this approach can prove to be extremely harmful for any product. Quality is something that must be taken care of right from the starting of a project. Moreover, it is comparatively easier to fix bugs in initial stages rather than once everything gets completed. There’s also a possibility that a critical bug might get missed in a rush or in order to fix a bug, you might have to change all of the following code lines that is no doubt a more tedious process.
Myths getting circulated across the industry is quite common, but the consequences of applying them in real processes can be devastating. Thus, to experience the real benefits of quality assurance and get hold of a high-quality end product, it is very crucial that the facts behind them are properly understood.
