cargo test from cmake add_test (in CI)

[cyrilleberger]

Hi,

I am wondering if anyone has successfully managed to run cargo test from cmake. I couldn't find a corrosion function for that, so I tried to do it manually:

add_test(NAME gqlite-rs COMMAND
    ${CMAKE_COMMAND}
    ${Rust_CARGO_CACHED} test
  WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}/)

I tried many variant, including adding -E env CARGO_TARGET_DIR=${CMAKE_BINARY_DIR}/cargo/build to reuse the same build, or even changing the location of rust cache, but no matter what I do I get all kind of errors (ranging from failure for rustc to find a toolchain, cargo failing to download...).

I should add that this fails only a CI, but works when I run locally with make test. I use Gitlab CI, not sure if that is the issue 🤔 I am wondering if anyone has a successful example of adding cargo test to cmake that they can share and run in a CI that use docker?

Usually these kinds of issues are easiest to debug if you can try the commands locally in the docker container (to avoid waiting on CI results).

Given some of the errors you got I would recommend looking into the environment variables corrosion sets, and trying to do the same (e.g. setting the environment variables to use a specific cargo / rustc tooolchain).

Hi, thank you for your answer. I tried that a bit, but couldn't figure out anything obvious, and fallback to running cargo test outside of cmake for ci. I will see if I find the time to revisit this at a later point.
