比较前的 Fitnesse Trim String 数据

Question

I wanted to ask if there is a way to trim String data before comparing it with the data in the table. For example, if we have

|MyCompareClass|
|getString?    |
|string1       |

And the result of getString() will be "string1 ". I want the comparison to be green and not Expected "string1". I'm looking for a way to do it without modifying the MyCompareClass source code. Any ideas?

Answer 1

You can write a custom string compare operator class:

public class MyCustomCompare: CellOperator, CompareOperator<Cell> {
    public bool CanCompare(TypedValue actual, Tree<Cell> expected) {
        return actual.Type == typeof(string);
    }

    public bool Compare(TypedValue actual, Tree<Cell> expected) {
        return actual.Value.ToString().Trim() == expected.Value.Text;
    }
}

Then register your class with the Fitnesse configure fixture:

|configure|processor|add operator|MyCustomCompare|

Answer 2

You could put !-string1 -! in your cell. All other options I can think of involve code changes to either SUT or fixture.
