NUnit TestFixtures不能与RestSharp一起使用

Question

I'm trying to use NUnit TestAttributes to create and delete a RestSharp RestClient

https://github.com/nunit/docs/wiki/TestFixture-Attribute

using NUnit.Framework;
using RestSharp;

namespace Sanitized.Sanitized.Steps
{
    [TestFixture]
    public class SetupAndTeardown
    {
        public RestClient restClient;

        [SetUp]
        public void Init()
        {

            restClient = new RestClient();
        }

        [TearDown]
        public void Cleanup()
        {

            restClient = null;
        }
    }
}

But, I get the error Object reference not set to an instance of an object. when trying to use this in another class ie with my automated steps.

I don't understand this, as I thought code that's in the [SetUp] [Teardown] attributes are called at the beginning and end of the test respectively.

Answer 1

You created a TestFixture , which is a class that contains tests. If the fixture had any tests, then NUnit would run them and would also run the setup before each test and the teardown after each test. Since you have no tests, that isn't happening. NUnit recognizes the fixture but finds nothing to run there.

You say that you have a problem when you "use" this fixture in another class. Test fixtures are not intended to be "used" by other code. Rather, they are run by NUnit.

For a better answer about how to do what you are trying to do, we first need to know what you are trying to do. When do you want the "setup" and "teardown" to run? How often should they run? Depending on those things, I can update this answer.

Replying further to your comment... If your tests are in another class, then that class is your test fixture. Is there a reason you don't want it to be the fixture?
