An approach is provided in which an information handling system analyzes correction information corresponding to an answer generated by a question answer system. The correction information includes a correction to the answer and captured variable information utilized by the question answer system to generate the answer. The information handling system selects input variables based upon the correction analysis and generates a test case that includes the selected input variables and the variable information. In turn, the information handling system tests the question answer system using the generated test case.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method implemented by an information handling system that includes a memory and a processor, the method comprising: analyzing, by the processor, correction information corresponding to an answer generated by a question answer system, wherein the correction information includes a correction to the answer and also includes a plurality of contributing variables that contributed to the generation of the answer; determining that at least one of the plurality of contributing variables is also a sensitive variable, wherein the sensitive variable corresponds to a condition of a patient; replacing, in response to the determination, a sensitive variable value corresponding to the sensitive variable with a generalized variable value; generating a test case based upon the generalized variable value; and testing the question answer system using the generated test case. 2. (canceled) 3. The method of claim 1 wherein the generalized variable value is based upon the sensitive variable value, and wherein the condition of the patient is a rare condition. 4. The method of claim 1 further comprising: selecting an influential variable in response to prioritizing the plurality of contributing variables; identifying an influential variable value corresponding to the selected influential variable; and including the influential variable value in the test case. 5. The method of claim 1 wherein the test case influences the question answer system to generate a different answer that corresponds to the correction. 6. The method of claim 1 further comprising: modifying a test plan based upon the sensitive variable, wherein the generated test case is based upon the modified test plan. 7. The method of claim 1 further comprising: receiving the correction from a user in response to providing the answer to the user; and capturing the plurality of contributing variables in response to receiving the correction from the user. 8. An information handling system comprising: one or more processors; a memory coupled to at least one of the processors; and a set of computer program instructions stored in the memory and executed by at least one of the processors in order to perform actions of: analyzing, by the processor, correction information corresponding to an answer generated by a question answer system, wherein the correction information includes a correction to the answer and also includes a plurality of contributing variables that contributed to the generation of the answer; determining that at least one of the plurality of contributing variables is also a sensitive variable, wherein the sensitive variable corresponds to a condition of a patient; replacing, in response to the determination, a sensitive variable value corresponding to the sensitive variable with a generalized variable value; generating a test case based upon the generalized variable value; and testing the question answer system using the generated test case. 9. (canceled) 10. The information handling system of claim 8 wherein the generalized variable value is based upon the sensitive variable value, and wherein the condition of the patient is a rare condition. 11. The information handling system of claim 8 wherein the one or more processors perform additional actions comprising: selecting an influential variable in response to prioritizing the plurality of contributing variables; identifying an influential variable value corresponding to the selected influential variable; and including the influential variable value in the test case. 12. The information handling system of claim 8 wherein the test case influences the question answer system to generate a different answer that corresponds to the correction. 13. The information handling system of claim 8 wherein the one or more processors perform additional actions comprising: modifying a test plan based upon the sensitive variable, wherein the generated test case is based upon the modified test plan. 14. The information handling system of claim 8 wherein the one or more processors perform additional actions comprising: receiving the correction from a user in response to providing the answer to the user; and capturing the plurality of contributing variables in response to receiving the correction from the user. 15. A computer program product stored in a non-transitory computer readable storage medium, comprising computer program code that, when executed by an information handling system, causes the information handling system to perform actions comprising: analyzing, by the processor, correction information corresponding to an answer generated by a question answer system, wherein the correction information includes a correction to the answer and also includes a plurality of contributing variables that contributed to the generation of the answer; determining that at least one of the plurality of contributing variables is also a sensitive variable, wherein the sensitive variable corresponds to a condition of a patient; replacing, in response to the determination, a sensitive variable value corresponding to the sensitive variable with a generalized variable value; generating a test case based upon the generalized variable value; and testing the question answer system using the generated test case. 16. (canceled) 17. The computer program product of claim 15 wherein the generalized variable value is based upon the sensitive variable value, and wherein the condition of the patient is a rare condition. 18. The information handling system of claim 15 wherein the information handling system performs additional actions comprising: selecting an influential variable in response to prioritizing the plurality of contributing variables; identifying an influential variable value corresponding to the selected influential variable; and including the influential variable value in the test case. 19. The computer program product of claim 15 wherein the test case influences the question answer system to generate a different answer that corresponds to the correction. 20. The computer program product of claim 15 wherein the information handling system performs additional actions comprising: modifying a test plan based upon the sensitive variable, wherein the generated test case is based upon the modified test plan.
