Infinity (FloatDomainError)

[Aaron Brown]

When trying to bisect a failing test, I get the following error:

That's kinda awesome! Any clue how to repro?

[Aaron Brown]

I'm not entirely certain yet. I believe that all my tests were failing
within the bisect. Once I fixed that, the bisect kicked off. I'll see if I
can make a treat scenario.

OK. I'll try that. Thanks.

[Ryan Davis]

Perfect. I have a repro with this:

#!/usr/bin/ruby

require "minitest/autorun"

class TestBorked < Minitest::Test
  10.times do |n|
    name = "test_borked_%03d" % (n+1)
    define_method name do
      assert false
    end
  end
end

OK. There's no good solution to this problem so I'm having it do the following:

% ruby -Ilib bin/minitest_bisect bug_009.rb

Nothing to verify against because every test failed. Aborting.

[Ryan Davis]

Fixed and will be released soon.
