Verify Generated Code and Deployed Code Artifacts

Verify generated C/C++ code and deployed code artifacts by using equivalence tests

With MATLAB^® Test™, you can verify generated C/C++ code and deployed code artifacts by using equivalence tests, which are also referred to as back-to-back tests.

Author equivalence tests that generate C/C++ code by using MATLAB Coder™ and verify that the generated code is functionally equivalent to the MATLAB source code. If you have Embedded Coder^®, you can measure the coverage of your generated C/C++ code when you run your equivalence tests.

Alternatively, you can author equivalence tests that generate deployed code artifacts by using MATLAB Compiler SDK™, including Java^® and Python^® packages and .NET assemblies, and test for equivalence.
