Accepted Answer

The number of defects per unit of software size (e.g., per KLOC)

Answer

Defect density measures the number of confirmed defects relative to the size of a software module, helping gauge code quality.

Question 4

Which assertion method should be used in Selenium tests (via TestNG/JUnit) to check that two values are equal?

Accepted Answer

assertEquals(expected, actual)
