assert should be replaced with assert_equal in a particular test case

Here is a test case from ActiveResource.

  def test_to_json
    Person.include_root_in_json = true
    Person.format = :json
    joe = Person.find(6)
    encode = joe.encode
    json = joe.to_json
    Person.format = :xml

    assert encode, json
    assert_match %r{^\{"person":\{"person":\{}, json
    assert_match %r{"id":6}, json
    assert_match %r{"name":"Joe"}, json
    assert_match %r{\}\}\}$}, json
  end

In the above test case 'assert' should be replaced by 'assert_equal'.

Patch will be attached through comment.
