MultiJson Load errors on be_json_eql matchers

[bradherman]

in my tests:

this passes

it {should be_json_eql(@league.id).at_path('id')}

this throws MultiJson load error

it {should be_json_eql(@league.href).at_path('href')}

Failure/Error: it {should be_json_eql(@league.href).at_path('href')}
 MultiJson::LoadError:
   795: unexpected token at 'http://0.0.0.0/api/leagues/259?post=3000'

What's your JSON?

[laserlemon]

JSON strings must be quoted with double quotes, not single. That may be your issue.

{
  "meta": {},
  "leagues": [
    {
      "id": 1,
      "name": "NFL/Football",
      "href": "http://0.0.0.0:5000/api/leagues/1"
    }
  ]
}

I'm inspecting now and it's weird. Check this out:

def parse_json(json, path = nil)
  ruby = MultiJson.decode("[#{json}]").first
  puts "GOT RUBY: #{ruby}"
  v = value_at_json_path(ruby, path)
  puts "GOT VALUE: #{v}"
  v
rescue MultiJson::DecodeError => e
  puts "GOT ERROR"
  MultiJson.decode(json)
end

gives

GOT RUBY: {"meta"=>{"version"=>1, "href"=>"http://0.0.0.0:3000/api"}, "leagues"=>"http://0.0.0.0:3000/api/leagues", "teams"=>"http://0.0.0.0:3000/api/teams", "rosters"=>"http://0.0.0.0:3000/api/rosters", "players"=>"http://0.0.0.0:3000/api/players"}
GOT VALUE: http://0.0.0.0:3000/api/teams
GOT ERROR

[bradherman]

It's picking up an error even though there isn't one. If I rescue the MultiJson.decode(json) with the @v (value_at_json_path return value), it works and all tests pass.

[laserlemon]

Try running it with this:

def parse_json(json, path = nil)
  puts "GOT JSON: #{json}"
  puts "GOT PATH: #{path}"
  ruby = MultiJson.decode("[#{json}]").first
  puts "GOT RUBY: #{ruby}"
  v = value_at_json_path(ruby, path)
  puts "GOT VALUE: #{v}"
  v
rescue MultiJson::DecodeError => e
  puts "GOT ERROR"
  MultiJson.decode(json)
end

I think I figured it out (and should have a long time ago). The JSON matchers are meant to compare JSON to JSON. Above, you're comparing JSON to Ruby. So when you give an expected string to the matcher, the matcher figures you're giving it JSON. So it's trying to parse "http://0.0.0.0:3000/api/leagues/313" as if it were JSON. Of course, that won't work and bombs how you're seeing. Does that make sense?

[alexpylko]

Try this
it {should be_json_eql(@league.href.to_json).at_path('href')}
