How it Works
How to Automate Embedded C and C++ Unit and Integration Testing with VectorCAST/C++
VectorCAST/C++ parses your source code and invokes code generators to automatically create the test code (stubs and drivers) required to construct a complete, executable test harness.
Once the test harness is constructed, VectorCAST/C++ can be used to build and execute test cases, show code covered, and report static measurements. Test data is maintained separately from the test harness, enabling easy automatic regression testing.
Components of the VectorCAST executable harness
- test driver
- source file(s) under test
- complete stubs for dependent functions
- source files for any dependent units that are not stubbed
The test harness is data-driven, meaning the harness reads test data during execution. This approach eliminates the need to compile and link a new executable harness for each new test.
VectorCAST/C++ also generates code coverage metrics which indicate which areas of the code that you are testing still have not been tested. The easy-to-read code coverage viewer indicates down to the line of code where there is testing left to be done and can support the different levels of coverage specified in various industry standards like: IEC 62304, ISO 26262, DO-178B/C and IEC 61508.
C and C++ Supported Compilers
For C and C++, VectorCAST is user-configurable for the compiler that you are using. If the compiler you are using is not on the list of supported C/C++ compilers, you simply need to configure the compile and link commands for your compiler.
