This is almost right, except:

  - the "exit" needs to be told which socket to use

  - we should do the "exit" even when the test fails early (so in
    test_when_finished)

  - the test_when_finished block will interpolate $HOME when setting up
    the block, which will break if it contains double-quotes or other
    special characters. It should use \$HOME.

    I suspect the "check" invocation needs to do so as well, though it
    is even trickier (we shove it into a single-quoted "-c" argument).

    I think you could get by in both cases with relative paths.

Using a relative path won't work since `git credential-cache --socket`
only accepts absolute paths. It shouldn't be too hard to escape the
string though.
