NoMethodError: undefined method `error' for Test::Unit::AssertionFailedError

[arika]

When an exception is raised in assert_difference or similar methods, test-unit-activesupport raises a NoMethodError.

sample code:

require "test/unit/active_support"
require "stringio"

class TestAssertions < ActiveSupport::TestCase
  setup do
    @logdev = StringIO.new
    self.tagged_logger = ActiveSupport::TaggedLogging.new(Logger.new(@logdev))
  end

  test "NoMethodError" do
    x = 1
    assert_difference("x") { raise }
  ensure
    pp @logdev.string
  end
end

result:
