Which report insight should be prioritized when deciding which test cases to enhance first?

Test cases with the longest names

Test cases that are rarely executed

Test cases that frequently fail due to application defects

Test cases that always pass quickly

What is the best way to communicate test automation results to non-technical stakeholders?

Use clear summaries with business impact and trends

Which report metric is most directly used to identify a trend of increasing instability in the application under test?

Pass rate over successive test runs

Number of test environments configured

A test automation suite has a high maintenance cost: 40 hours per week. The suite catches an average of 15 defects per release, but 10 of those are low-severity and would likely be caught by manual testing. The team is considering reducing the suite's scope. What should they do?

Analyze the ROI of the suite by comparing the cost of maintaining all tests against the value of the defects they uniquely catch.

Reduce the suite immediately because the maintenance cost is too high.

Increase the maintenance budget to improve the suite's reliability.

Keep the suite as is because it catches 15 defects per release.

A team has an automated regression suite that runs nightly. The report shows the suite takes 6 hours to execute, and the team spends 20 hours per week fixing broken tests. The suite detects an average of 5 high-severity defects per release that would otherwise reach production. Management asks whether the automation is worth the cost. What should the test lead do?

Recommend stopping automation because 20 hours of maintenance per week is too high.

Calculate the ROI by comparing the cost of maintenance and execution time against the cost of defects that were prevented.

Recommend increasing the automation budget to reduce execution time.

Report only the defect detection rate to management as proof of value.
