Abstract: An information handling system executes test cases against a code that includes a set of functions, wherein the execution is performed at least twice using a different trace switch value. The system also identifies trace logs associated with each test case, and maps each test case to one or more functions based on the association of the trace logs with each test case.

Abstract: A computer system obtains a to-be-processed bytecode file from an archive file of a target application. The archive file is used for creating or updating an installation package of the target application. The computer system collects, from the to-be-processed bytecode file, bytecodes that correspond to N optimization tasks respectively, wherein N being a positive integer. One optimization task is used for optimizing one type of bytecode. The computer system performs an optimization operation on the collected bytecodes that correspond to the optimization tasks respectively, so as to obtain an optimized bytecode file.
