Percentage of work done in test environment preparation is a metric that measures how much of the required test environment setup has been completed. This metric is useful for monitoring the test progress because it indicates whether the test environment is ready for executing the planned test cases or not.

Traceability is the ability to identify related items in documentation and software, such as requirements, design specifications, code modules, test cases, test results, etc. Traceability helps to ensure that all requirements are covered by tests, that all tests are linked to requirements, and that any changes in requirements or software can be traced to their impact on other items.

Test implementation and execution is the stage of the Fundamental Test Process where testers write detailed steps for executing each test case (test procedures), prepare and prioritize test cases for execution, execute test cases and record results, compare actual results with expected results and report discrepancies as incidents.

The version of the application is missing from the defect report. This is a valid criticism because it is important to specify which version of the software was tested when the defect was found, as this can help to identify and reproduce the defect, and to verify if it has been fixed in a later version.

The test case execution effort is dependent on the build quality, because if the build quality is low, then more defects will be found and more re-testing will be required, which will increase the test execution effort. On the other hand, if the build quality is high, then fewer defects will be found and less re-testing will be required, which will reduce the test execution effort.

The ideal number of regression test cycles is as many as time and budget allow, because regression testing is done to ensure that no new defects have been introduced by changes or fixes in the software, and that all previously fixed defects are still fixed. Therefore, more regression test cycles can increase the confidence in the software quality and reliability.

Regression testing can be applied to any test level where changes or fixes have been made to the software or its environment, and there is a risk that these changes may have introduced new defects or re-introduced previously fixed defects. Therefore, regression testing can be done at component, integration, system and acceptance test levels.

Test design is the process of transforming general testing objectives into tangible test conditions and test cases that can be executed and verified against expected results. Test design involves identifying test techniques, coverage criteria, input data, expected outcomes and other test parameters.

The test manager is not right because there is no direct relationship between branch coverage and statement coverage. Branch coverage measures how many branches in the control flow have been executed by a set of test cases, while statement coverage measures how many statements in the code have been executed by a set of test cases. It is possible to achieve high branch coverage without achieving high statement coverage, if some statements are not part of any branch condition or are not reachable by any test case.
