最满意答案

符号执行最着名的用法是测试输入生成。 例如， KLEE是一种使用符号执行为C程序生成测试输入的工具。

另一个应用程序是断言检查。 如果合同是指前后条件，那么是，符号执行也可用于此目的。

The most famous usage of symbolic execution is test input generation. For example, KLEE is a tool that generates test inputs for C programs using symbolic execution.

Another application would be assertion checking. If by contract you mean pre and post conditions, then yes, symbolic execution can also be used for that purpose.
