To test a report, specifically the recent hire training report within a human resources application, the most direct and effective method is to run the report definition against actual data. This approach allows for the evaluation of the report's functionality, ensuring it meets the requirements and accurately reflects the data.
* D. Run the report definition using the contents of a database table: This option involves executing the report definition to generate the report using data stored in a database table. It allows for the assessment of how well the report handles real data, including the correctness of the information displayed, the performance of the report, and whether it meets the product manager's requirements for reviewing hiring practices.
Creating a copy of the rule (A) and initializing the rule with test data using the run rule window (B) can be part of the development or debugging process but might not fully test the report under realistic conditions.
Identifying a data test page to unit test the rule (C) is more applicable to testing rule logic rather than report output.
