How to write fitnesse code for a method which accepts 2 parameters

Question

I'm newbie to fitnesse and trying to run a simple calculator class which has "add" method accepting 2 parameters and returning the result. Can anyone help me to write the firnesse code for this, my method is as below

public int add(int a, int b) {
    return a+b;
}

What are you trying to achieve? Do you want to write a test that checks whether add returns the right result for various values of a and b? What test framework are you using Fit or Slim? — Fried Hoeben, Nov 02 '14 at 08:46
yes, correct, i want to chk if add return correct rsults for diff values of a and b. I'm using Fit framework — user85, Nov 08 '14 at 09:31

I believe you are trying to get a table like:

|AddFixtureTest |
|left|right|sum?|
|1   |1    |2   |
|2   |4    |6   |

This requires a java class like:

import fit.ColumnFixture;

public class AddFixtureTest extends ColumnFixture {
    public int left;
    public int right;

    public int sum(){
        return add(left, right);
    }
    private int add(int a, int b) {
        return a+b;
    }
}

I assume Slim is fine by you and I'm gonna use script table for this (more out of habit):

|script| <class name> |
|add;| <variable1> | <variable2> |

As simple as that. And, make sure you are using the right libraries and pointing to the location of the where the class file is.

Example:

|import|
fitnesse.slim.test |

If you are interested in knowing why I have placed a semi-colon after "add", and how script table works, please go through this:

You can get the FitNesse tutorial there for .Net code. I tried to describe how to use FitNesse for different types of testing. If you want to check two parameters on the output you can do the following:

Return IEnumerable implementation with classes, which contains get and set properties (see here). NetRunner will use get properties if it can, otherwise it will use set properties. As a result, it will set all available data first and then compare items left.
You can use out parameters in the tests, so you can return several different values and check them

The correct answer is:

|script:<classPackage>.<ClassName>|
|check|add;|8|8|16|

First tell the script to navigate to the correct class. In the next line you have to call either a method or a constructor. You can call the method by it's name (or fancy smansy digibetic words that vaguely match) and tack on a semicolon. But anything put into the pipe-blocks after that will be interpreted as parameters for that method. So how do you put the expected output? The trick is to tell the FitNesse engine you need a result, with the keyword 'check'. This will make the final pipe-block be the field for the expected result, in this case 16.
