Functional testing focuses on verifying the functionality of a software system, ensuring that it meets the specified requirements. Non-functional testing validates aspects such as performance, usability, security, and reliability.
A test environment is a setup that replicates the production environment where the software will ultimately be deployed. It provides a controlled and realistic platform for testing, ensuring that the software performs as expected in different scenarios.
Verification involves checking that a software system or component meets specified requirements and specifications. Validation ensures that the software meets the customer’s expectations and satisfies the intended purpose.
Exploratory testing is a dynamic and ad hoc testing approach where testers simultaneously design, execute, and learn from tests. It relies on the tester’s domain knowledge and intuition to uncover defects and understand the behaviour of the software.
Load testing assesses the performance and behaviour of a software system under specific expected or anticipated load conditions. It helps identify performance bottlenecks, and scalability problems, and determine if the system can handle the anticipated user load.
Some best practices for defect management include accurately documenting defects, prioritizing them based on severity and impact, assigning ownership, tracking the status of defect resolution, conducting root cause analysis, and continuously improving the defect management process.
