NUnit – specifying a method to be called after every test

nunitunit testing

Does NUnit let me invoke a method after every test method?

e.g.

class SomeClass
{
   [SomeNUnitAttribute]
   public void CalledAfterEveryTest()
   {
   }
}

I'm aware of [SetUp] and [TearDown], but that only works for the tests in the current class. I want something like [TearDown], except it runs after every unit test, whether its in the current class or not. Possible?

The [TearDown] Attribute marks the cleanup method.

If you want it for multiple classes I believe you can add the teardown method to a base class and inherit from that in every test class that needs the teardown behaviour.

Ruby – In Ruby’s Test::Unit::TestCase, how to override the initialize method

As mentioned in Hal Fulton's book "The Ruby Way". He overrides the self.suite method of Test::Unit which allows the test cases in a class to run as a suite.

def self.suite
    mysuite = super
    def mysuite.run(*args)
      MyTest.startup()
      super
      MyTest.shutdown()
    end
    mysuite
end

Here is an example:

class MyTest < Test::Unit::TestCase
    class << self
        def startup
            puts 'runs only once at start'
        end
        def shutdown
            puts 'runs only once at end'
        end
        def suite
            mysuite = super
            def mysuite.run(*args)
              MyTest.startup()
              super
              MyTest.shutdown()
            end
            mysuite
        end
    end

    def setup
        puts 'runs before each test'
    end
    def teardown
        puts 'runs after each test'
    end 
    def test_stuff
        assert(true)
    end
end

.net – NUnit – cleanup after test failure

Since version 2.5.7, NUnit allows Teardown to detect if last test failed. A new TestContext class allows tests to access information about themselves including the TestStauts.

For more details, please refer to http://nunit.org/?p=releaseNotes&r=2.5.7

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