Describe the bug
make test on a freshly cloned repository does not find any tests.

To Reproduce
Steps to reproduce the behavior:

1. git clone https://github.com/nasa/cFS.git
2. cd cFS
3. cp cfe/cmake/Makefile.sample Makefile
4. cp -r cfe/cmake/sample_defs sample_defs1
5. make SIMULATION=native ENABLE_UNIT_TEST=true prep
6. make
7. make install
8. make test

Observed behavior

Note - something like this could be caused by submodules being out of sync. Can you confirm if you did a "git submodule update' as part of this?

There was a recent change that affected the directory structure of the build tree, so if this was out of sync it would potentially manifest as not finding any test files.

Yes, I forgot to include the git submodule init and git submodule update commands from my steps to reproduce. I did run git submodule update as part of my setup and got those results. I tried it both on master and integration-candidate and the same thing happened.

[jphickey]

Did you do this before or after the "cp cfe/cmake/Makefile.sample Makefile" step?

The sample makefile might contain a line "ARCH ?= native" or "ARCH ?= native/default_cpu1" reflecting the recent change to the build tree.

Check your generated build tree and see if the actual build binaries are in the "native" subdir or a "native/default_cpu1" subdir.

[fletching]

I updated the submodules prior to copying the Makefile, even after changing to the integration-candidate branch.

The sample Makefile I copied has ARCH ?= native on master and ARCH ?= native/default_cpu1 on integration-candidate. The directories for the binaries are correct for both branches.

Ah hah --- I see it -- ENABLE_UNIT_TEST=true should be ENABLE_UNIT_TESTS=true

🤦 Yes! Thank you!!
