Error parsing test list

[glaslos]

Running revel test github.com/revel/examples/chat vanilla checked out. Added error handling here: https://github.com/revel/cmd/blob/master/revel/test.go#L136

This is how the test looks like:

[
  {
    "Name": "ApplicationTest",
    "Tests": [
      {
        "Name": "TestThatIndexPage"
      },
      {
        "Name": "TestThatIndexPageWorks"
      }
    ],
    "Elem": {}
  }
]

Failed to get test list[error json: cannot unmarshal object into Go struct field TestSuiteDesc.Elem of type reflect.Type]

For some reason Elem is encoded as an {} and can't be Unmarshalled into a reflect.Type
