Subject: [ruby-core:55042] [ruby-trunk - Bug #8417] assert_in_epsilon(-1, -1) failed


Issue #8417 has been updated by no6v (Nobuhiro IMAI).


Oh, I'm verry sorry, but I used test-unit external gem (2.5.4).
After removing it, the test-unit default gem (2.0.0.0) works fine.
Would you please to close this (or mark as 3rd patry's) issue? Thanks.

Though I'm not sure the difference between "test" and "minitest",
minitest seems to be succeeded.

 require "minitest/unit"

 MiniTest::Unit::TestCase.new(?-).assert_in_epsilon(-1, -1)
