What are the hardware requirements for running the checks?

[m1mir]

My attempt at running the tests failed because I ran out of memory, on a system that had 16 gigabytes of RAM.

Approximately what are the hardware requirements for testing the project the way it is described in the CONTRIBUTING.md?

Yes, unfortunately the tests are quite heavy to run.
First, ensure to only run the tests command and not the checks (which builds even more things).
Second, try adding the --max-jobs 1 flag to limit the number of simultaneous builds (although your crash might happen earlier in the eval phase).

Finally, you could rely on the CI to run the tests by creating a PR. You will be able to access all logs.

My primary machine is a laptop with 16GB. That struggles to run the tests most of the time, though there may be other issues on my end.

I also have a desktop with 64GB, but I don't use it much because I have yet to convert it over to nixos and I often run into weird quirks of using nix on another distro.

After running tests for a few minutes:

EDIT: 30 mins later, it's still maxed out swap & ram, but it has finished evaluating and is now building!

Thank you for the the information! I've managed to run the test suite on a laptop with similar properties to the one that Matt described and with NixOS with similar resource usage.

Based on what you all said and, based on the results it seems to me that 32GB memory( meaning RAM and swap) is a practical minimum for running the checks locally.
