Problems with Dictionary<string, string>

[Thaoden]

I have a Dictionary<string, string> in my system under test.

The following table is throwing an error:

| Test |
| Server Name | Server Details |
| server For EPV | null |

fitSharp.Fit.Exception.FitFailureException: Column 'Server Name' not used.

What am I missing? Can I also use Dictionary<string, object>?

What does the code for 'Test' look like?

More complete test:

| Get Singleton By Identifier | ldapServer_EPV |
| Ldap Section |
| Test |
| Server Name | Server Details |
| server For EPV | null |

GetSingletonByIdentifier returns a Configuration-object:

public class Configuration
{
    (...)
    public LdapSection {get; set;}
}

public class LdapSection
{
    public ConcurrentDictionary<string, string> Test {get; private set;}
    public LdapSection()
    {
        Test = new ConcurrentDictionary<string,string>();
        Test.TryAdd("serverForEPV","serverForEPV");
        Test.TryAdd("serverIVS1","serverIVS1");
    }
}

fitSharp is using servername and serverdetails as method names to call on the dictionary values. Since the dictionary values are strings, this is failing. You can use tostring as a method name:

|test| |tostring| |serverForEPV| |serverIVS1|

[Thaoden]

Does this mean that I can only check for the value parts and not for the presence of a key?

[jediwhale]

The default handling for a Dictionary is to check the values. If you want to check for the keys, you'd need some other method available for firSharp to use, e.g.:

public IEnumerable<string> TestKeys { get { return Test.Keys; } }

|testkeys| |tostring| | ... |

or you could make the dictionary the system-under-test and check methods on it:

|with|test| |ensure|contains key| ... |

The default handling for a Dictionary is to check the values.

Well then I don't understand the examples in http://fitsharp.github.io/Fit/FixtureWrapper.html and http://fitsharp.github.io/Fit/SetFixture.html; can you elaborate on them, please?

[jediwhale]

The 'named collection' fixtures (Array, Set, Subset, Row) are checking a collection of objects. The second row lists a set of fields, properties or methods that are checked on each object in the collection. The problem is a dictionary has two objects for each item in its collection, a key and a value. So to check keys and values, you need a method to extract the key-value pairs:

public IEnumerable<KeyValuePair<string, string>> TestKeyValues() {
    return Test.AsEnumerable().OrderBy(p => p.Key);
}

|test key values| <== return a collection of KeyValuePair objects |key|value| <== list the properties to be checked on each object |...|...| <== expected values |...|...| etc

Alright, I think I get it... Thanks!
