than 100, so the corresponding questions are generated directly. The following class implements efficiency considerations in two scenarios. If traversal is fast, you can directly call AddTest to add one more time. If the query is fast, you can use KindOfTestNeed to extract the query conditions, the results generated by the current code are the same each time. If there is a real library, you can use the Randomization of the query results and the Randomization of the KindOfTestNeed condition to g
