NUnit Test with an array of values

Question

I am trying to use NUnit with the values attribute so that I can specify many different inputs without having 100 separate tests.

However now I am realizing there are times where I want to use the same set of inputs but on very different test like below.

Is there a way that I can specify all the values in one place, like an array and use the array for each values attribute?

I want to make sure that the test runs as 100 individual tests, instead of 1 test that runs 100 values.

I have looked in the Nunit documentation, but I cannot find a way to accomplish this. Any ideas?

Code:

[Test] public void Test1([Values("Value1", "Value2", "Value3", ... "Value100")] string value) {     //Run Test here }  [Test] public void Test2([Values("Value1", "Value2", "Value3", ... "Value100")] string value) {     //Run Test here }  [Test] public void Test3([Values("Value1", "Value2", "Value3", ... "Value100")] string value) {     //Run Test here } 

Answer 1

TestCaseSource attribute is suitable here.

See example:

private string[] commonCases = { "Val1", "Val2", "Val3" };  [Test] [TestCaseSource(nameof(commonCases))] public void Test1(string value) {     .... }  [Test] [TestCaseSource(nameof(commonCases))] public void Test12(string value) {     .... } 

Answer 2

You can use FactoryAttribute on test method, instead of ValuesAttribute on param. Read more about this here.

Edit: Alexander is right. FactoryAttribute was a temporary part of API. The right path is to use TestCaseSourceAttribute.
