[PATCH 2/8] test/*.rb: test/unit compatibility

[Eric Wong]

assert() in test/unit does not automatically stringify the failure
message, unlike minitest.  I don't have a strong opinion regarding
minitest and test/unit, but the deprecation notices in minitest 5
are annoying, so perhaps using Test::Unit via minitest shim is a
better way to go.
