Testing focuses on system control and error detection, with product orientation and corrective actions. Testing is about checking the behavior of the application, while quality assurance is about making the overall quality level of the project better each day. Some may worry about the risks involved in extending the team: every additional tester added in a product development team makes the development cycle more expensive and less competitive than other products that offer the same function.
On the other hand, it is impossible to find a person who would be familiar with all stages of product development at such a high stage that they will be able to competently assess its effectiveness from the start. Therefore, in most cases, Testers can perform Quality Assurance duties, because they are familiar with every aspect of the product and specific conditions such as business logic behind it.
This situation is also fairly reasonable because being aware of the problems that emerge in the product development process, it is also easier for team members to pinpoint their main roots in the process of their manufacture. After analyzing these two concepts, we can compare them according to their purpose, subject matter, definitions, type of action, and orientation. QA controls the testing process and verifies that the software is capable of working under certain conditions.
Testing focuses on case studies, implementation, and evaluation. Therefore, quality assurance is mainly about optimizing the process in such a way that quality is achieved. To track the success of such quality measures, manual tests are often used and their respective reports. It covers all processes, policies, standards, tools, training, etc. Testing is a very small part of a well-integrated quality assurance strategy. A good quality assurance strategy should be both proactive and reactive.
The methodology that connects quality assurance with testing is quality control. This methodology focuses largely on the search for errors in the operation of the application by testing software at various test levels and types.
The more types of the tests covered, the better it is for the overall tendency of discovering defects. Each level of tests covers different types of usage, e. Quality control is heavily product-oriented. Based on that, the engineers responsible for quality control write appropriate tests answering the demands.
From time to time, quality control may be considered as the end of the production line or last stop of maintenance, however, this is not completely true. The intent of quality control is to prove that the product does work as intended by breaking it or finding differences between requirements and current working results, but testing itself is an endless action and testing cycles will continue until a decisive person responsible for maintaining the overall quality plan decides to stop.
Testing is in fact a part of quality control activities. It is the process of building a system with the intention of finding faults. In this approach, frequent detection is just as important as maintaining overall quality every day of the development cycle.
Quality assurance should be the commitment of every person involved in the development work. The quality of software cannot be ensured by one or even several QC activities performed by one directly delegated person. The first part in a properly planned and executed Quality Assurance process is the Quality assurance strategy. It defines the approach and activities to be carried out during software development to achieve the defined quality of the application under development.
QA should have a holistic view of the project while creating the QA strategy and must address all aspects with respect to software projects from requirements capture to development. Next up is Quality Control QC — a set of activities used to ensure quality in a product or a service. The goal of QC is to ensure a proper implementation of the processes defined in Quality Assurance strategy. The main focus of QC is to validate that the product meets the specifications and requirements of the customer.
It is a reactive process that helps to confirm that the product works as expected. Quality Control activities can be performed by Software Testers with specialist testing skills.
As the development process draws to a close, you arrive at Software Testing or simply Testing as one way in which Quality Control can be implemented. Testing involves validating the product against specifications and customer requirements, finding and reporting defects. It includes various testing techniques such as functional , non-functional , acceptance testing to detect software issues.
A tester identifies what-if scenarios, exceptions, gaps in user stories, and acceptance criteria that are not testable, thus preventing defects instead of finding them at the end. In summary, QA is a process , while testing is an activity embedded within QC. While the goal of QA and QC is to have a quality product at the end, both use different approaches and tools. Other activities that contribute to quality in addition to testing include groomings, plannings, and code reviews. All of these and more are part of the QA process.
We take an active role in groomings and plannings, reviewing user stories from testing perspective, identifying possible risks, gaps, discrepancies, etc. Quality assurance should be everyone's responsibility. One cannot assure software quality by carrying out one or even several QC activities. Teams embed quality from the start by working together, listening to each other, helping each other, choosing the right tools and supporting process. Quality is about being responsible about one's work from the first thought to the last minute of service in production.
Let's call ourselves what we actually are. We are testers and we are part of QA process. Devbridge welcomes Director of Product Design. This app works best with JavaScript enabled.
Are we quality assurance or testers?
