Which software metric measures lines of code, code coverage, defect density and code maintainability index?

The correct answer is Product metrics.

Key Points

• Product metrics are used to measure the characteristics of software products, such as:
  • Lines of code (LOC): A measure of the size of the software by counting the number of lines in its source code.
  • Code coverage: A measure of how much of the code is tested during software testing.
  • Defect density: The number of defects found per unit size of the software, such as per 1,000 lines of code.
  • Code maintainability index: A measure of how easily the code can be maintained, modified, or understood.

Additional Information

• Product metrics focus on the quality and characteristics of the final software product.
• They help in assessing the reliability, usability, and performance of the software.
• These metrics provide insights into areas of improvement for the software development process.
• They are distinct from process metrics (which measure the efficiency of the development process) and project metrics (which measure project management aspects like cost and schedule).
