Final answer:
The biggest issue with the defect report is that it does not specify what the expected data should be, which is essential for developers to diagnose and fix the problem. Including the expected result, detailing the discrepancy, and confirming the reproducibility steps are ways to improve such a report.
Step-by-step explanation:
The biggest problem with the defect report described is option D: The developer won't know what the tester expected to see. While the description mentions that the data in column 1 is incorrect and provides a screenshot as evidence, it fails to clearly state what the correct data should be. This omission makes it difficult for a developer to understand the discrepancy between the actual result and the expected result, thus hindering the process of troubleshooting and fixing the issue.
In order to improve the defect report, the following information should be included:
- Expected results: A clear description of what the correct data should look like.
- Actual results: Specific details on how the current data differs from the expected results.
- Steps to reproduce: Confirm that the steps included are complete and clear so that the developer can replicate the issue.
These enhancements would significantly improve the communication between the tester and developer, leading to more efficient resolution of the defect.
