Nunit test setup method with argument

Question

Can we have a test set up method with arguments? I need a different set up for every test in a fixture.

Do we have something (or similar way) as the hypothetical idea :

[SetUp] [Argument("value-1")] [Argument("value-2")] [Argument("value-3")] public void InitializeTest(string value) {     //set env var with value }

It can be done using the TestFixture attribute with a parameter.

If all the tests in the class depend on the same parameter this is the way to go.

The class will need a constructor with the same parameter passed to the TestFixture attribute.

See Parameterized Test Fixtures on https://github.com/nunit/docs/wiki/TestFixture-Attribute

[TestFixture("Oscar")] [TestFixture("Paul")] [TestFixture("Peter")] public class NameTest {     private string _name;      public NameTest(string name)     {         _name = name;     }      [Test]     public void Test_something_that_depends_on_name()     {         //Todo...     }      [Test]     public void Test_something_that_also_depends_on_name()     {         //Todo...     }     //... } 

This code is from the nunit documentation website:

[TestFixture("hello", "hello", "goodbye")] [TestFixture("zip", "zip")] [TestFixture(42, 42, 99)] public class ParameterizedTestFixture {     private readonly string eq1;     private readonly string eq2;     private readonly string neq;      public ParameterizedTestFixture(string eq1, string eq2, string neq)     {         this.eq1 = eq1;         this.eq2 = eq2;         this.neq = neq;     }      public ParameterizedTestFixture(string eq1, string eq2)         : this(eq1, eq2, null)     {     }      public ParameterizedTestFixture(int eq1, int eq2, int neq)     {         this.eq1 = eq1.ToString();         this.eq2 = eq2.ToString();         this.neq = neq.ToString();     }      [Test]     public void TestEquality()     {         Assert.AreEqual(eq1, eq2);         if (eq1 != null && eq2 != null)             Assert.AreEqual(eq1.GetHashCode(), eq2.GetHashCode());     }      [Test]     public void TestInequality()     {         Assert.AreNotEqual(eq1, neq);         if (eq1 != null && neq != null)             Assert.AreNotEqual(eq1.GetHashCode(), neq.GetHashCode());     } }
