How to pass an object to a Method using FitNesse and Slim

Question

I'm using FitNesse and SLIM and I would like to be able to pass an object to a method and can't seem to find out how? How do you do this using SLIM?

So for example I want to build a call object

!|FitTesting.MakeCall                             |
|ANI       |Call Type|Call Id|Call Key No| Data|
|4403951403|2        |2000   |8000       |5000 |

I want to store that object in a symbol or variable name CallObject

Then I want to use that object in the Start Call method.

|script | FitTesting.PracticeCallTestFixture|
|Initialize Call Fixture|
|Start Call|<<With Call Object>>
|check|Check For Call|true|
|Finalize Phone Desktop|

I tried to use a dictionary but got the following exception

EXCEPTION_:fitSharp.Machine.Exception.ParseException1[System.String]: Parse parameter 1 for 'UpdateECCData' type System.Collections.Generic.Dictionary2[System.String,System.String] failed. ---> System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Here is the fit markup

!|FitTestingConnectCTI.MakeCall                                                                |
|ANI       |Call Type|Router Call Key Id|Router Call Key Day|Update ECC Data                   |
|4403951403|2        |2000              |5000               |!{ANI:4403951403,StateAbbr:OH}    |

Here is my method call

   public void UpdateECCData(Dictionary<string,string> eccDictionary)
    {
        if (eccDictionary != null)
        {
            if (eccDictionary.Count > 0)
            {
                foreach (KeyValuePair<string, string> keyValuePair in eccDictionary)
                {
                    ECCData.Add(keyValuePair.Key,keyValuePair.Value);
                }
            }
        }
    }

Answer 1

For c# I don't know. For Java you could either register a custom type , or rewrite the method to accept a Hashtable (ie Dictionary) and use the Hash widget .

Answer 2

You can also pass the parameter in Fitnesse in Json format, then implement a method in your code that converts from json to Dictionnary. What I did - using Java - is the following:

1. Pass a string in Fitnesse having jsonFormat. For example {"username":"xxx", "password":"yyy"}

2. In the code the method does the following:

   public void login(String credentials){ Map<String,String> cred = (Map<String, String>)JSONValue.parse(credentials); }

In this case you will be only dealing with json on the Fitnesse side. u just need to change the way of converting json to map (json to dictionary in C#) Hope this helps a bit.
