Consider the following example of TAS metrics. Time to execute automated tests Speed and efficiency of TAS components Which of the following statements is TRUE?

Question

Options

• AA and B are both internal TAS metrics
• BA is an internal TAS metric and B is an external TAS metric
• CA and b are both external TAS metric
• DA is and external TAS metric and b is an internal TAS metric

• A
  91% (50)
• B
  2% (1)
• C
  5% (3)
• D
  2% (1)

Explanation

Option A is correct because both metrics measure the performance of the Test Automation System (TAS) itself - internal TAS metrics evaluate how well the automation framework operates, not what it produces. "Time to execute automated tests" reflects the TAS's own execution performance, and "Speed and efficiency of TAS components" directly assesses the TAS infrastructure - both are inward-facing measurements.

Options B and D are wrong because they misclassify one metric as external - external TAS metrics measure the effect of the TAS on the testing process (e.g., defect detection rate, test coverage achieved), not the TAS's own operational characteristics. Option C is wrong because neither metric measures testing outcomes; calling both external would confuse TAS performance with TAS results.

Memory tip: Think of it this way - internal metrics look inside the machine (how fast does it run, how efficient are its parts?), while external metrics look outside at what the machine delivers (did it find bugs, how much of the code did it cover?). Both items in this question describe the machine itself, so both are internal.
