Testing Setup
Unit Tests
Nocompile
The test suite has to be able to test a number of different setups generated by different choices in Make/MkFlags. Some of these choices, for example compiling with or without GPU, will also generate different namespaces. However, we still want to preserve the ability to test only for a single case of choosing the compilation flags.
The testing Makefiles have therefore been configured to only run certain tests for certain compilation flags, using a NOCOMPILE = XXX statement, where XXX is the corresponding compilation flag. If we, for example, want to write a test that works only if compiles without GPU acceleration, we can use this flag to configure the test this way in the preamble
/*******************************************************************************
*
* NOCOMPILE= WITH_GPU
*
* This test is only compiled if the WITH_GPU flag is inactive
*
*******************************************************************************/
Notice, that there is no space between NOCOMPILE and =. Conversely, we can configure tests that only test the GPU-version by negation
/*******************************************************************************
*
* NOCOMPILE= !WITH_GPU
*
* This tests only the GPU-version of HiRep
*
*******************************************************************************/
If we want to make sure that multiple flags are active, we can connect them over &&.
/*******************************************************************************
*
* NOCOMPILE= !WITH_GPU && !WITH_MPI
*
* This tests only the Multi-GPU compiled version of HiRep
*
*******************************************************************************/
If the test does test multiple, but not all possible setups, we can write them down using multiple lines.
/*******************************************************************************
*
* NOCOMPILE= WITH_GPU
* NOCOMPILE= WITH_MPI
*
* This test can be compiled either if MPI or GPU acceleration is disabled.
