CSA Quality Assurance Programs 2

Question 1

Which QA metric measures the percentage of defects found during testing versus total defects found (including those found in production)?

Accepted Answer

Defect Removal Efficiency (DRE)

Answer

Defect Removal Efficiency (DRE) measures the ratio of defects removed before release to the total number of defects, indicating the effectiveness of the QA process.

Question 2

In a QA program, what is the primary purpose of a test plan document?

Accepted Answer

To define the scope, approach, resources, and schedule for testing activities

Answer

A test plan defines the scope, objectives, approach, resources, environment, and schedule needed to guide all testing activities within a project.

Question 3

What QA technique involves executing software without actually running the code, relying instead on human review?

Accepted Answer

Static testing

Answer

Static testing reviews artifacts such as code, requirements, or design documents without executing the program, catching defects early in the lifecycle.

Question 4

A company tracks the number of defects per thousand lines of code. This measurement is known as:

Accepted Answer

Defect Density

Answer

Defect Density is calculated as the number of defects divided by the size of the software (often per KLOC), providing a normalized quality indicator.

Question 5

Which type of testing verifies that new code changes have not adversely impacted existing functionality?

Accepted Answer

Regression testing

Answer

Regression testing re-executes previously passing test cases after code changes to ensure existing functionality remains unbroken.
