CSM Quality Assurance & Testing Practices

Question 1

What is the main purpose of Quality Assurance (QA) in software development?

Accepted Answer

To ensure the software meets predefined requirements

Answer

The main purpose of Quality Assurance (QA) in software development is to establish and maintain the desired level of quality throughout the entire development lifecycle. QA focuses on preventing defects by ensuring that the processes used to develop the software are effective and that the final product consistently meets all specified functional and non-functional requirements. It's a proactive approach to quality.

Question 2

Which of the following is an example of a testing method used in QA?

Accepted Answer

Unit testing

Answer

Unit testing is a fundamental testing method used in QA where individual components or 'units' of source code are tested in isolation to determine if they are fit for use. This method helps developers identify and fix defects early in the development cycle, before they can propagate and become more costly to resolve in later stages. It's a key part of ensuring code quality.

Question 3

What is regression testing?

Accepted Answer

Testing the code after changes to ensure no defects are introduced

Answer

Regression testing is a crucial type of software testing performed after code changes, bug fixes, or new feature implementations. Its purpose is to ensure that these modifications have not inadvertently introduced new defects or negatively impacted existing functionalities. By re-running previously passed test cases, regression testing helps maintain the stability and integrity of the software over time.

Question 4

What is the difference between manual and automated testing?

Accepted Answer

Manual testing is more flexible, while automated testing is faster for repetitive tasks

Answer

Manual testing relies on human testers to execute test cases, allowing for subjective evaluation, exploratory testing, and adaptability to unexpected scenarios. Automated testing, conversely, uses scripts and tools to perform predefined tests, making it highly efficient and consistent for running the same tests repeatedly, especially for regression testing. This distinction highlights their complementary strengths in the software development lifecycle.

Question 5

What is load testing?

Accepted Answer

Testing how the software performs under stress or heavy load

Answer

Load testing is a type of non-functional testing designed to evaluate a software system's behavior under a specific expected load. Its primary purpose is to determine the system's stability, response time, and resource utilization when accessed by a large number of users or processing a significant amount of data. This helps identify performance bottlenecks and ensure the software can handle real-world usage demands.
