Software testing is one of the most essential and fundamental activities in the development of a project, as it enables the processes, working methods and tools necessary to ensure the quality of any development. However, today, we continue to encounter problems when it comes to understanding software testing as an investment, even in the most traditional projects where we assumed that testing activities were normalized.
According to Software Testing Company QAwerk, In order to be able to detect any errors in time and guarantee that the product complies with all the established premises, testing must exist in all phases of a project: from the taking of customer requirements, through follow-up meetings, to the delivery of the final product. What’s more, a project that lacks this process in all its phases ends up generating a higher economic cost and a greater effort during the testing phase.
In most cases, during the planning of a project, the QA team has a few days established for testing, usually coinciding days before deployment. In case of delays during development, the testing phase is usually the most affected, even in some cases to be eliminated for lack of time. It is often considered that software testing is a costly but also dispensable phase when what it really achieves is to ensure the quality of the product, so we would be talking about a guaranteed investment. And it is that, the detection of errors in final phase, later correction of these and the testing of the correction generates greater effort in hours and greater economic investment than having planned the existence of the QA team in all the cycle of life of the development from the beginning, being able to prevent the errors beforehand. The key is to prevent before, not to detect at the end.
A good functional and technical understanding of the business on the part of the QA team guarantees, in turn, what type of tests will be necessary to apply in each testing phase and how to apply them. In this case, we are talking about automated testing. It is more than proven that currently, it takes twice as long to test a functionality than to develop it. Also, exploratory tests can only detect a percentage of errors, also influenced by the short time available to perform them and the number of people available to carry it out.
Automated testing achieves the elimination of errors arising from manual testing. In addition, each software update requires regression tests to ensure that the product continues to function correctly and that none of the modifications has resulted in one or more collateral errors. Regression tests produce extra effort in hours, as well as greater economic expense, making automation necessary, thus saving project time and improving reliability. To this end, it is necessary to analyze which test cases are likely to be automated, always prioritizing those that are most critical and those that are likely to generate uncontrolled errors.
For example, in an application, it is always going to generate more errors the management of an extensive form or a screen of search of information with its corresponding filter, than the access to one or more screens from a menu. Therefore, all those screens that interact with backend or services will be the most priority to be automated. On the other hand, through a continuous integration cycle, we will be able to minimize time and effort in regression tests, accelerate product development and updates, reduce the TTM (Time to Market), at the same time that an increase in test coverage is achieved, minimizing errors in execution.
In short, it is necessary to be aware of the importance of software testing and the inclusion of quality equipment in all phases of product development, without this being considered an economic disadvantage in the planning of a project. Without a doubt, it is much better to detect errors at the right time, thus generating a material time to correct them, than to detect them before the delivery of the product or an important step to production.
