What metrics were used in your testing experience?

• Defects:

  • Total number of defects found.
  • Defect density (number of defects per unit size of the product, e.g., per 1000 lines of code or per functional area).
  • Defect discovery rate (number of defects found per unit time).
  • Defect fixing rate (number of defects fixed per unit time).
  • Distribution of defects by severity (Critical, Major, Minor, Trivial).
  • Distribution of defects by type (functional, UI, performance, etc.).
  • Percentage of re-opened defects (Reopened).

• Test coverage:

  • Requirements coverage (percentage of requirements covered by test cases).
  • Code coverage (line, branch, condition coverage if code coverage analysis tools are used).
  • Test scenario coverage (percentage of developed or executed test cases).

• Test execution efficiency:

  • Number of executed and failed test cases.
  • Percentage of successful test case execution.
  • Test suite execution time (for automation).
  • Testing performance (number of test cases executed per unit time).

• Performance and load metrics (if relevant testing was conducted):

  • System response time.
  • Throughput (number of transactions per second).
  • Resource utilization (CPU, memory, disk).
  • Number of concurrent users.

• Test automation metrics:

  • Percentage of automated test cases.
  • Number of automated regression tests.
  • Stability of automated tests (frequency of false negatives).
  • Time for developing and maintaining automated tests.

• Customer satisfaction metrics (indirectly, through feedback, number of incidents in operation).

These metrics help evaluate testing progress, product quality, testing activity effectiveness, and make release stage decisions.
