A test analyst is analyzing test results and finds that the defect detection rate is high, but the defect removal efficiency (DRE) is low. The project is under time pressure, and the release date cannot be moved. What should the test analyst do to improve the situation?

Increase the number of test cases to find more defects

Ask developers to work overtime to fix all defects

Prioritize the most critical defects and ensure they are fixed before release

Recommend postponing the release to allow more time for defect fixing

During test result analysis, a test analyst notices that a specific module consistently fails when tested with boundary values but passes with typical values. What is the most appropriate first step to identify the root cause of this pattern?

Retest the module with only typical values to confirm the module is working correctly.

Investigate the common conditions and inputs across the failing boundary tests to isolate the root cause.

Immediately report all boundary value failures as a single high-severity defect.

Assign the failures to the development team without further analysis since they are responsible for fixing defects.

A test analyst is analyzing the results of a test cycle and notices that many defects are found in the 'reporting' module, but the defects are all of the same type (e.g., incorrect calculations). What should the test analyst do to improve defect detection?

Remove some reporting test cases because they are not effective

Add more test cases that focus on different calculation scenarios

Ask the development team to fix the calculation logic

Increase the priority of reporting defects in the defect tracking system
