Nix evaluation tests for various lib functions.
|
|
|
|
Since these tests are implemented with Nix evaluation, error checking is limited to what `builtins.tryEval` can detect, which is `throw`'s and `abort`'s, without error messages.
|
|
If you need to test error messages or more complex evaluations, see ./modules.sh, ./sources.sh or ./filesystem.sh as examples.
|
|
|
|
To run these tests:
|
|
|
|
[nixpkgs]$ nix-instantiate --eval --strict lib/tests/misc.nix
|
|
|
|
If the resulting list is empty, all tests passed.
|
|
Alternatively, to run all `lib` tests:
|
|
|
|
[nixpkgs]$ nix-build lib/tests/release.nix
|
