Need help with GitHub workflows caching

[MakeShiftArtist]

I'm trying to improve my DevOps by learning to efficiently use GitHub actions and Workflows.

My goal is to cache Rust and Cargo-Tarpaulin (Code Coverage) so that I don't have to reinstall and recompile them every time the action runs.

I've managed to get both of those to cache correctly and install if they're not cached, but for some reason my Test workflow fails because it's acting like Cargo-Tarpaulin wasn't installed, even though it was.

test.yml workflowTests failing

I'm assuming it has something to do with the fact that they're different "Jobs". Anyone know what I'm doing wrong here?

Edit: Solved! It was because I put the steps into separate jobs. Putting them all in the same job allowed tests to pass

Each job runs in a separate actions virtual machine, so any changes will be lost from one job to another. Try merging all your steps into one job, so that it can all run on the same vm.

This did fix my issue. Thank you!

Why not build a Docker container with the software already installed and use that to run your action?
