Day 2 of 2
Using Stubs and Mocks
Objective: Add stub functions for callees without an implementation, and write mocks for callees that need to be replaced in testing.
- Stubs and mocks overview
- Stubbing undefined global variables
- Stubbing undefined functions
- Mocking defined functions
- Using mock variables
Authoring Tests with xUnit C API
Objective: Become familiar with simple tests in the xUnit C API, and compile and run tests directly with an external toolchain.

- Using assessment macros
- Exporting test results
- Importing xUnit tests into Polyspace projects
Authoring Complex Tests with xUnit C API
Objective: Author tests using the xUnit C API that are organized into suites, parameter sweep tests, and tests that assess data of custom types.
- Configuring test suites
- Authoring parametrized tests
- Comparing custom data type objects
- Measuring code coverage
- Measuring execution time and memory usage
Running Tests on Target
Objective: Cross-compile and run existing test cases on an external target and profile for performance and code coverage.
