Getting started with NUnit’s RowTest

Maybe I’ve been living under a rock, but I just found out that the latest versions of NUnit support [RowTest]!  Over the weekend, I was about to replace NUnit with mbUnit because I need [RowTest], but thankfully, after a bit of surfing, I found this post by David Hayden (dated December 2007).  David’s post described an add-in for NUnit that has since been rolled into NUnit proper.

Step 1: Download / install NUnit version 2.4.7 or newer.

Step 2: Add a reference to NUnit.framework.dll and NUnit.framework.extensions.dll.

nunit.references

Step 3: Add using NUnit.Framework and using NUnit.Framework.Extensions to your test class.  I include SyntaxHelpers because I like using the .That(condition, Is.) syntax.

nunit.using

Step 4: Decorate your tests with [RowTest], add individual cases and add parameters to your test that match the data from the test cases.

[RowTest]
[Row("foo", false, true)]
[Row("", false, false)]
[Row(null, false, false)]
[Row("___-__-____", false, true)]
[Row("___-__-____", true, false)]
public void testRequiredFieldValidator(string data, bool ignoreChars, bool result)
{
    var rule = new RequiredFieldValidationRule("test field");
    rule.IgnoreMaskCharacters = ignoreChars;
    ValidationResult temp = rule.Validate(data, CultureInfo.CurrentCulture);
    Assert.That(temp.IsValid, Is.EqualTo(result));
}

Step 5: Run :-)

nunit.results.1

nunit.results.2

Notes: I did have to download the a new version of TestDriven.net, but other than that, it was a pretty simple process.

    Personally, I don’t see the need for RowTest. If you want to perform a test with multiple sets of input, I presume those different sets are intended to acheive different results. Just create a non-test method that takes those parameters, and then multiple test methods to call it, with each test providing different input parameters. Not only does it acheive the same result, but you can now name the individual “rows” for the effect they are trying to provoke.

    In the current release of NUnit (2.5.3.9345) there is no NUnit.framework.extensions.dll, and I didn’t find RowTest in any of the other assemblies shipped with it. So what happened to RowTest?

    They disappeared in 2.5, the release notes just state, that they were removed, but not why. Did they move into a separate download, or is there any reasons not to use them anymore?

    It’s a great article explaining NunitASP. One request is that, please post a new blog that explains how to use NUnitASP. Thanks for your effort.
