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.
