Advantages of quality assurance  

Software reliability

Having QA engineers do a deep and successful analysis of the software ensures that the product will satisfy the quality standards set by the stakeholders. They will ensure the requirements are met, and all marginal cases are properly handled.
Besides functional, QA engineers cover non-functional aspects like security, load and performance, and accessibility testing, making the end product more stable.

User satisfaction

Bugs discovered by end-users in production are not only more expensive to fix than the ones found in earlier phases. They can also negatively affect the software owner’s reputation, causing significant money loss.
By simulating usage scenarios, QA engineers can identify malfunctions in any part of the system as early as possible and prevent them from rolling out to production, affecting end-users satisfaction.

Domain knowledge

QA experts are extremely important team members with extensive experience and knowledge in the business domain. Usually, they become a knowledge hub, and everyone turns to confirm their understanding of all the requirements.

Development efficiency

Most bugs are found during projects' development or early testing phase by a dedicated QA engineer before the code is shipped to production. The sooner the bug is found, the cheaper it is to fix it.
QA engineers validate the requirements and quickly spot a potential issue or a corner case on a specific feature request. This decreases the time needed for software development and the development costs over time.

Testing efficiency

Having QA engineers write automated tests increases testing efficiency. This enables faster test execution, a decreased margin for human error when compared to manual testing, and an increased testing frequency with an option to run tests every night and after each deployment to the testing environment.

Speed and cost

By writing automated tests, QA engineers can speed up the deployment process. This also reduces the cost of regression testing and increases the overall quality of the software.

Quality assurance testing services - FAQ

Software quality assurance (QA) is a process designed to improve customers’ experience, and advance the quality, speed, and security of your software products. QA testing aims to catch bugs and feature issues before a software product goes live.

Quality Assurance engineers verify that the software is fully built to match your clients' needs. They continuously communicate with all stakeholders to validate that your software meets their requirements. QA engineers focus on improving the software development process and ensuring your product is bug-free.

Automation testing involves QA engineers writing test scripts that automate test execution. It includes a set of instructions to be performed on target platforms to validate a feature or expected outcome.

Manual testing requires QA engineers to be highly involved in everything from analyzing the product, test case creation, and test data preparation to actual test execution and test execution documentation, with a critical view on the application and constantly suggesting improvements.
