What is the difference between Quality Engineering and Quality Assurance?
One of the core functions of organizations is to ensure that their products meet the set quality standards. Quality Engineering (QE) is concerned with principles and practices of product quality assurance and control. It is deployed in every phase of product development. QE involves Quality Assurance (QA) and Quality Control (QC) to fulfil the demands of businesses and magnify the customer experience.
QA is different from QE in the sense that it determines that your product meets the specified requirement and aims to maintain the quality of the finished product while QE lays emphasis on improving the product at every step of its development. All in all, QE tests, examines, and enhances the product quality throughout the development lifecycle while QA ensures that the product meets quality guidelines or client agreements.

What is the main purpose of functional testing?
Functional testing ensures that the software operates as expected by validating its features against predefined requirements. It focuses on user interactions, verifying that inputs produce correct outputs. This helps identify usability issues, broken functionality, and compliance with business logic. It ensures a smooth user experience.
Why is structural testing important in software development?
Structural testing evaluates the internal workings of the software, analyzing code logic, data flow, and control structures. It helps developers detect hidden bugs, optimize performance, and improve maintainability. By reviewing code execution paths, it ensures that all scenarios are tested. It reduces potential failures and enhances overall software reliability.
When should you use functional testing over structural testing?
Functional testing is best when validating software behavior based on user expectations and business requirements. It ensures that each function performs correctly in real-world scenarios. Structural testing, however, is more useful for checking code quality, efficiency, and performance. This makes it essential for debugging and optimization efforts.
What are the challenges in functional and structural testing?
Functional testing may overlook internal code errors since it focuses on external behavior, potentially missing edge cases. Structural testing, on the other hand, requires deep programming knowledge and is time-consuming. Both approaches have limitations, making it necessary to balance them for thorough software validation.
