junitparameter exception method should have no parameter

I stumbled across this article while looking for an issue to a similar problem. I was getting an exception like this:

java.lang.Exception: Method x should have no parameters

It turns out I was using the wrong import for the @Test annotation. I originally used import org.junit.Test; but what I needed to use was import org.junit.jupiter.api.Test;

Long story short, make sure you are checking your imports, sometimes the auto-generated ones aren't really what you want.

Add @RunWith(JUnitParamsRunner.class) annotation above class as

@RunWith(JUnitParamsRunner.class)
public class TestClass {

Also you need to import

import junitparams.JUnitParamsRunner;

You are using wrong import for @Parameters - it should be junitparams.Parameters, not org.junit.runners.Parameterized.Parameters
