This is very useful in conjunction with meta.pkgConfigModules, as the
new tester can use the list provided by this meta attribute as a default
value for moduleNames, making its usage in passthru.tests very
convenient.
For backwards compatibility, a shim under the old name is maintained
with a warning.
When lib overrides were used, before this commit, they would not be made
available in the configuration evaluation of nixosTest's nodes.
Sample code:
``` nix
let
pkgs = import ./. {
overlays = [
(new: old: {
lib = old.lib.extend (self: super: {
sorry_dave = builtins.trace "There are no pod bay doors" "sorry dave";
});
})
];
};
in
pkgs.testers.runNixOSTest {
name = "demo lib overlay";
nodes = {
machine = { lib, ... }: {
environment.etc."got-lib-overlay".text = lib.sorry_dave;
};
};
testScript = { nodes }:
''
start_all()
machine.succeed('grep dave /etc/got-lib-overlay')
'';
}
```
See docs.
Follow-up work:
- Existing packages should be converted
- `defaultPkgConfigPackages` should assert on `meta.pkgConfigModules`
and let `tests.pkg-config` alone test the build results.

stdenv: print message if structuredAttrs is enabled
stdenv: add _append
reduces the chance of a user doing it wrong
fix nix develop issue
output hooks don't work yet in nix develop though
making $outputs be the same on non-structuredAttrs and structuredAttrs
is too much trouble.
lets instead make a function that gets the output names
reading environment file '/nix/store/2x7m69a2sm2kh0r6v0q5s9z1dh41m4xf-xz-5.2.5-env-bin'
nix: src/nix/develop.cc:299: std::string Common::makeRcScript(nix::ref<nix::Store>, const BuildEnvironment&, const Path&): Assertion `outputs != buildEnvironment.vars.end()' failed.
use a function to get all output names instead of using $outputs
copy env functionality from https://github.com/NixOS/nixpkgs/pull/76732/commits
Fixes the problem introduced by 12b3066aae
which caused nixos/release.nix to return the wrong attributes, while
intending to only affect nixos/lib's runTest.
This also removes callTest from the test options, because callTest is
only ever invoked by all-tests.nix.
Examples: support has to be added to https://github.com/nix-community/nixdoc
'nixdoc --category testers --description "nixpkgs testers" --file ./pkgs/build-support/testers/default.nix'
we will have more testers in the future so they should have their own
location
putting 'testers' in args will also make it simpler to use multiple testers
