How to make NUnit stop executing tests on first failure

Question

We use NUnit to execute integration tests. These tests are very time consuming. Often the only way to detect a failure is on a timeout.

I would like the tests to stop executing as soon as a single failure is detected.

Is there a way to do this?

Answer 1

Using nunit-console, you can achieve this by using the /stoponerror command line parameter.

See here for the command line reference.

Answer 2

I'm using NUnit 3 and the following code works for me.

public class SomeTests {
    private bool stop;

    [SetUp]
    public void SetUp()
    {
        if (stop)
        {
            Assert.Inconclusive("Previous test failed");
        }
    }

    [TearDown]
    public void TearDown()
    {
        if (TestContext.CurrentContext.Result.Outcome.Status == TestStatus.Failed)
        {
            stop = true;
        }
    }
}

Alternatively you could make this an abstract class and derive from it.
