We include several types of tests in SUNDIALS: unit tests, integration test and performance tests. These tests are run via as part of our Continuous Integration suite <CI>.
Unit Tests
The unit tests reside in two places: test/unit_tests and in files named test_ within examples/. With few exceptions, SUNDIALS unit tests should return an exit code indicating if the test was successful or not. I.e., they should be self-contained and not require any output file to determine success or failure.
Integration Tests
The integration tests are dual purpose; they serve as tests and also examples for users. They are found in examples/. The integration tests produce output that is checked against an output file, i.e. an answer file, to determine if the test passed or failed. See Answers <Answers> for details.
Performance Tests
These tests are benchmarks of SUNDIALS performance and are found in benchmarks/. Refer to Continuous Performance Testing <CPT> for more detail.
