NUnit: Fail Test when OneTimeTearDown fails

Question

Abstract goal: I’m working with NUnit (3.9.0 at the moment). Some work to finish the tests is done in the OneTimeTearDown method. When this work fails, I need an indication, i.e. one or more tests should fail.

Background: I’m implementing PACT Tests using NUnit as the Unit Test framework. On the consumer, after all tests are run, I have to generate and upload the PACT file to the PACT broker. If this fails, e.g. when the pact broker is down, I need to have an indication; i.e. one or all tests should fail.

Question: Is this possible using NUnit? If so: How? Or would there be a better approach to achieve my objective?

You could call the same assert methods from your OneTimeTearDown method as you call from the tests. Here is example that fails test run from teardown method:

[TestFixture]
public class SomeClassTests
{
    [OneTimeTearDown]
    public void Cleanup()
    {
        Assert.Fail("Failed to upload file to the PACT broker");
    }

    [Test]
    public void TestMethod()
    {
        Assert.Pass();
    }
}

Here is execution result in ReSharper UT runner:

Another option to fail test run from teardown method is to throw exception.

Unfortunately I can’t reproduce your solution. Using NUnit 3.9.0, Visual Studio 2015 & ReSharper 10.0.2. Neither in the ReSharper UnitTest Runner, nor in the Visual Studio Test Explorer I can get a hint that something went wrong. I only see it in the Test-Text-Output. But this is very unhandy, I doubt the developers would see this hint. And we would need to hack something on the build servers. I also can’t find any flag to set in NUnit to reproduce your solution. Or any setting in ReSharper. – kryz Feb 05 '18 at 09:58
It works for me using NUnit 3.9.0, Visual Studio 2015 and ReSharper 2016.1.1. So probably this feature was introduced in some version of ReSharper UT Runner after 10.0.2. – CodeFuller Feb 06 '18 at 14:30
With an updated ReSharper Version it works as you described. Whether I could convince all our developers to even install ReSharper is another question ;) And this solution only covers the development machines. On our build servers the builds are still green. Therefor I would prefer to have a way where an actual TestCase fails. This would cover all scenarios. Nevertheless, thanks a lot for your input! – kryz Feb 07 '18 at 13:58

Yes, only you can use ReSharper, the output is clearly visible.but you also can use output or Nunit 2.X，Please see the detailsNunit3 console doesn't show test output continuously
