The concept that I have is something like this:

def test_cache_thingy(nix: Nix, binary_cache: BinaryCache):
    name = binary_cache.path(NAR([
        ('file1', NAR.file(b'foo bar')),
        ('abc', NAR.dir([
            ('file2', NAR.file(b'baz', executable=True))
        ]))
    ])

    nix.nix(['path-info', '--store', binary_cache.url])
    # ....

We currently have the ability to generate custom NARs on the fly in functional2. This is pretty cool, but it only really utilized for generating invalid NARs to test the parser. Currently Lix contains a kinda bad testing http server and the tests using it are more janky than necessary. Also we currently use NixOS tests for a bunch of binary cache stuff and other network interaction which we could *absolutely* run against localhost instead, if we had better testing fixtures. The concept that I have is something like this: ```python def test_cache_thingy(nix: Nix, binary_cache: BinaryCache): name = binary_cache.path(NAR([ ('file1', NAR.file(b'foo bar')), ('abc', NAR.dir([ ('file2', NAR.file(b'baz', executable=True)) ])) ]) nix.nix(['path-info', '--store', binary_cache.url]) # .... ```

jade added the
