Building and Running Tests

Building and Running Tests#

The functional tests are enabled by default, and can be enabled/disabled with the CMake build parameter -DBUILD_FUNCTIONAL_TESTS=True/False. Only the tests relevant to the enabled backends and target domains will be built.

Building tests for BLAS and LAPACK domains requires additional libraries for reference.

  • BLAS: Requires a reference BLAS library.

  • LAPACK: Requires a reference LAPACK library.

For both BLAS and LAPACK, shared libraries supporting both 32 and 64 bit indexing are required.

A reference LAPACK implementation (including BLAS) can be built as the following:

git clone https://github.com/Reference-LAPACK/lapack.git
cd lapack; mkdir -p build; cd build
cmake -DCMAKE_INSTALL_PREFIX=~/lapack -DCBLAS=True -DLAPACK=True -DLAPACKE=True -DBUILD_INDEX64=True -DBUILD_SHARED_LIBS=True ..
cmake --build . -j --target install
cmake -DCMAKE_INSTALL_PREFIX=~/lapack -DCBLAS=True -DLAPACK=True -DLAPACKE=True -DBUILD_INDEX64=False -DBUILD_SHARED_LIBS=True ..
cmake --build . -j --target install

and then used in oneMath by setting -REF_BLAS_ROOT=/path/to/lapack/install and -DREF_LAPACK_ROOT=/path/to/lapack/install.

You can re-run tests without re-building the entire project.

To run the tests, either run test binaries individually, or use ctest CMake test driver program.

# Run all tests
ctest
# Run only Gpu specific tests
ctest -R Gpu
# Exclude Cpu tests
ctest -E Cpu

For more ctest options, refer to ctest manual page.
