使用现有工具链设置执行代码探查
如果您使用 Polyspace Test xUnit API 编写 C/C++ 测试，则可以探查源文件和测试以计算代码覆盖率、代码执行时间或内存使用。要计算这些度量，请使用 polyspace-code-profiler 命令对源代码进行插桩，将测试与插桩的代码一起编译，然后执行测试。
系统命令
polyspace-code-profiler | (System Command) Profile your source code for calculating C/C++ code coverage, code execution time, and memory use |
CMake 函数
pstest_add_profiling_runtime | (CMake) Create target for compiling a custom run-time library for code profiling |
pstest_instrument_target | (CMake) Instrument a target for profiling |
pstest_add_convert_target | (CMake) Create target for converting test or code profiling results to standard Polyspace Test format |
pstest_add_report_target | (CMake) Generate XML and HTML reports from test or code profiling results |
MATLAB 函数
pstest.exportToPolyspaceProfilingResults | (MATLAB Function) Export coverage results from Simulink Coverage, Simulink Test, or MATLAB Test to Polyspace Test |
