NUnit doesn't find tests in assembly

Question

Hi,

I inherited an assembly with MSTest, but these tests were run using nunit-console on the build machine (not sure how it worked). So I decided to sort it out and change them to proper NUnit tests, but now nunit-console (or gui) can't find any tests. They run just fine using ReSharper test runner though. Any idea what could be missing?

Answer 1

Are your test fixtures, classes and methods, public? They have to be for NUnit to find them.

Answer 2

Check:

• Is the class public?
• Does it have a public parameterless constructor (e.g. the default one if you don't specify any other constructors)
• Does it have the [TestFixture] attribute at the class level?
• Is each test public?
• Does each test have the [Test] attribute?
• Is each test parameterless?

I believe some versions of NUnit were able to find tests based on their names, e.g. TestFooBarBaz() without the [Test] attribute, but I don't know what the state of this is now - it could explain the discrepancy though.

Answer 3

Thanks for help, everyone. Upgrading to the latest NUnit framework fixed the problem (all the obvious things you suggested where ok).

Frederik Gheysels, you can try that as well I guess.
