TestFixtureTearDown is not executed after exception in TestFixtureSetUp

[Birgit Vera Schmidt]

Issue now tracked at https://github.com/nunit/nunit-framework/issues/32

(NUnit 2.5.10.11092 wit GUI runner)

The behaviour of TearDown and TestFixtureTearDown in case of an Exception in the corresponding SetUp is described in the same way, but behaves differently.

Decription of TearDown:
So long as any SetUp method runs without error, the TearDown method is guaranteed to run. It will not run if a SetUp method fails or throws an exception.

Description of TestFixtureTearDown:
So long as any TestFixtureSetUp method runs without error, the TestFixtureTearDown method is guaranteed to run. It will not run if a TestFixtureSetUp method fails or throws an exception.

I have the following two very simple classes:

==============================================================
  [TestFixture]
  public class Base
  {
    [TestFixtureSetUp]
    public void TestFixtureSetUp()
    {
      Console.WriteLine("Running TestFixtureSetUp Base");
    }
    [SetUp]
    public void SetUp()
    {
      Console.WriteLine("Running SetUp Base");
    }
    [Test]
    public void TestBase()
    {
      Console.WriteLine("Running Test Base");
    }
    [TearDown]
    public void TearDown()
    {
      Console.WriteLine("Running TearDown Base");
    }
    [TestFixtureTearDown]
    public void TestFixtureTearDown()
    {
      Console.WriteLine("Running TestFixtureTearDown Base");
    }
  }
==============================================================
  [TestFixture]
  public class Derived : Base
  {
    [TestFixtureSetUp]
    public new void TestFixtureSetUp()
    {
      Console.WriteLine("Running TestFixtureSetUp Derived");
    }
    [SetUp]
    public new void SetUp()
    {
      Console.WriteLine("Running SetUp Derived");
    }
    [Test]
    public void TestDerived()
    {
      Console.WriteLine("Running Test Derived");
    }
    [TearDown]
    public new void TearDown()
    {
      Console.WriteLine("Running TearDown Derived");
    }
    [TestFixtureTearDown]
    public new void TestFixtureTearDown()
    {
      Console.WriteLine("Running TestFixtureTearDown Derived");
    }
  }
==============================================================

Executing TestDerived works as expected:
==============================================================
Running TestFixtureSetUp Base
Running TestFixtureSetUp Derived
Running SetUp Base
Running SetUp Derived
Running Test Derived
Running TearDown Derived
Running TearDown Base
Running TestFixtureTearDown Derived
Running TestFixtureTearDown Base
==============================================================

Now I introduce an Exception in SetUp of Base:
==============================================================
    [SetUp]
    public void SetUp()
    {
      Console.WriteLine("Running SetUp Base");
      throw new Exception("Exception in SetUp Base");
    }
==============================================================

Executing TestDerived now gives this output:
==============================================================
Running TestFixtureSetUp Base
Running TestFixtureSetUp Derived
Running SetUp Base
Running TearDown Derived
Running TearDown Base
Test 'Avl.TestAutomationFramework.Infrastructure.UnitTests.TestDriver.Derived.TestDerived' failed: SetUp : System.Exception : Exception in SetUp Base
    Base.cs(18,0): at Avl.TestAutomationFramework.Infrastructure.UnitTests.TestDriver.Base.SetUp()

Running TestFixtureTearDown Derived
Running TestFixtureTearDown Base
==============================================================

Since the behaviour of TearDown and TestFixtureTearDown in case of an exception in the corresponding SetUp function is described the same way, word by word, I would expect that if there was an Exception in TestFixtureSetUp Base, then also both TestFixtureTearDown Derived and TestFixtureTearDown Base will be called.

However, if I remove the Exception from SetUp Base again and instead add one to TestFixtureSetUp Base...
==============================================================
    [TestFixtureSetUp]
    public void TestFixtureSetUp()
    {
      Console.WriteLine("Running TestFixtureSetUp Base");
      throw new Exception("Exception in TestFixtureSetUp Base");
    }
==============================================================

... then running TestDerived gives the following output:
==============================================================
Running TestFixtureSetUp Base
Test 'Avl.TestAutomationFramework.Infrastructure.UnitTests.TestDriver.Derived.TestDerived' failed: TestFixtureSetUp failed in Derived

TestFixture failed: SetUp : System.Exception : Exception in TestFixtureSetUp Base
   at Avl.TestAutomationFramework.Infrastructure.UnitTests.TestDriver.Base.TestFixtureSetUp() in D:\git\TestAutomationFramework_V2013\Projects\Infrastructure\UnitTests\TestDriver\Base.cs:line 13
==============================================================
