Reviewing tests developed by others would not typically be performed by a tester, but rather by a test leader or a peer reviewer1 . Reviewing tests developed by others is an activity that involves checking the quality and completeness of the test cases or procedures and providing feedback or suggestions for improvement1 . The other options are tasks that would typically be performed by a tester. Option A is a task that would typically be performed by a tester, because it involves preparing and acquiring the test data that are needed for executing the test cases or procedures1 . Option B is a task that would typically be performed by a tester, because it involves setting up and checking the test environment that supports the execution of the test cases or procedures1 . Option C is a task that would typically be performed by a tester, because it involves writing test summary reports that document the results and outcomes of the test execution1 .
