What type of information is not included in the results of a test case for an expression rule?

The results of a test case for an expression rule are designed to capture essential information necessary for validating the functionality and performance of that rule. The inclusion of input values used, expected outputs, and any error messages received provides a comprehensive overview of the rule's operation and helps to identify any issues.

Historical performance, on the other hand, refers to the previous executions or evaluations of the expression rule over time, which typically relates to how well the rule performed in past scenarios. This information is not critical for understanding the immediate results of a test case; rather, test cases focus on the current execution context, ensuring that inputs are handled correctly and that outputs match expectations. Therefore, historical performance does not contribute to the specific evaluation of a test case in the moment, making it the type of information not included in the results.
