QA, confidence and value in the present and future
Perhaps more important than the idea or business model behind a product or service, it is its solidity that truly wins the confidence of its users leading someone to trust and chose one solution over another, even when the price is higher. This solidity and stability in IT, as well as in many other areas, is highly linked to the work of QA Engineers whose main task is to test it.
The tests performed by QA engineers go through acceptance or rejection criteria and the results allow a better understanding of the state of the product at a particular moment. In this way it is possible to identify and correct any errors before they reach the end user.
“In the near future, it is expected that this branch of engineering will evolve at a breakneck pace in order to guarantee greater security, stability and, consequently, confidence in all software we use.“
It is after delivery to the customer that the problems caused by the lack of tests will have the most impact. These can translate in ways as vast as just a decrease in the quality of the experience, or, in other issues with totally catastrophic consequences. Thus, it can be said that the earlier, in the development process, a fault is discovered and corrected, the less impact it will have and consequently the less expensive it will be to correct it.
The veracity of this basic QA principle means that more and more, especially in software projects, there is an investment in manual testing in order to guarantee the expected behavior of each new function, but also automatic regression tests whose main objective is to ensure that the introduction of new features does not cause any damage to the existing ones. The repeatability and increasing dimension of the battery of regression tests throughout the project requires that the tester also be a developer, developing his own test code, guaranteeing results in a fast and automated way.
This duality of principles has many advantages, and typically translates into a capacity for critical and objective perspective with the purpose of achieving the best possible final product, as well as, ensuring a well-structured communication bridge with developers thus leading to easier interaction and teamwork, which, in turn, will streamline the entire process.
Investment in QA is increasingly considered an essential part of the development process, not only due to the immediate results in terms of detecting errors but also due to the dynamics it brings to the teams. It currently is an area of engineering in substantial growth with more and more certified testers who add unquestionable value to the projects they operate.
In the near future, it is expected that this branch of engineering will evolve at a breakneck pace in order to guarantee greater security, stability and, consequently, confidence in all software we use. Incrementally advanced test frameworks and the use of artificial intelligence will allow results to be obtained more quickly and consistently, finding the source of failures automatically and combining this data in order to reveal potentially problematic areas or parts of the product.
