Isn't the above going to cause 'test' to error out?

    $ mkdir -p t/test-results
    $ >t/test-results/a.exit
    $ >t/test-results/b.exit
    $ test t/test-results/*.exit = 't/test-results/*.exit'
    -bash: test: too many arguments

I'd think you'd want to capture the result of the expansion of
t/test-result/*.exit as a string and compare that instead.
