3. Testing OpenFAST

The OpenFAST test suite consists of glue code and module level regression tests and unit tests. The regression tests compare locally generated solutions to a set of baseline solutions. The unit tests ensure that individual subroutines are functioning as intended.

All of the necessary files corresponding to the regression tests are contained in the reg_tests directory. The unit test framework is housed in unit_tests while the actual tests are contained in the directory corresponding to the tested module.

3.1. Configuring the test suite

Portions of the test suite are linked to the OpenFAST repository through a git submodule. Specifically,

• r-test

• pFUnit

Tip

Be sure to clone the repo with the --recursive flag or execute git submodule update --init --recursive after cloning.

The test suite can be configured with CMake similar to OpenFAST. The default CMake configuration is suitable for most systems, but may need customization for particular build environments. See the Understanding CMake section for more details on configuring the CMake targets. While the unit tests must be built with CMake due to its external dependencies, the regression test may be executed without CMake.

3.2. Test specific documentation

• 3.2.1. Unit test
• 3.2.2. Regression test

3.3. Continuous integration

A TravisCI configuration file is included with the OpenFAST source code at openfast/.travis.yml. The continuous integration infrastructure is still under development, but the status for all branches and pull requests can be found on the TravisCI OpenFAST page.

For development and testing purposes, a version of the TravisCI test can be run locally with Docker. The code snippet below outlines starting a TravisCI image on Docker.

# Running a travis ci image on docker locally
