Abstract: This application includes a case generation unit and a case execution unit. The case generation unit obtains an access request received by to-be-tested software, determines a value range of a request parameter in the access request based on the access request, and generates test cases for the access request based on the value range. Subsequently, the case execution unit executes the test cases for the to-be-tested software.
