UnTested Unity Coroutineでテスト。 C#

このコードは動かない。

    [Test]
    public IEnumerator APIAccessTest ()
    {
        Dictionary <string, object> webInfo = new Dictionary<string, object> ();

        string userId = "00001";
        // yield return StrarCoroutine (apiAccess.FireWebAPI (userId,
(value) => {
            webInfo = value;}));
        yield return apiAccess.FireWebAPI (userId, (value) => {
            webInfo = value;});

        Dictionary<string, object> result = new Dictionary<string, object>();

        if (opponentInfo != null)
        {
            result = webInfo ["result"] as Dictionary<string, object>;
        }

        Assert.IsTrue (result.Count >= 0, "Result is equal and more than 0.");
    }

・実際にテストしたいコード

public class ApiAccess : MonoBehaviour
{
    public IEnumerator FireWebAPI (string user_id,
System.Action<Dictionary<string, object>> returnData)
    {
        WWWForm form = new WWWForm();
        form.AddField ("user_id", user_id);
        WWW www = new WWW ("http://example.com", form);
        yield return StartCoroutine (WaitForRequest (www, returnData));
    }

    private IEnumerator WaitForRequest (WWW www,
System.Action<Dictionary<string, object>> returnData)
    {
        yield return www;
        if (www.error == null)
        {
            Dictionary<string, object> dict = Json.Deserialize
(www.data) as Dictionary <string, object>;
            returnData (dict);
        }
        else
        {
            Debug.LogError("Error " + www.error + " URL " + www.url);
            returnData(null);
        }
    }
}

↓修正後

 [Test]
