Use parameterized test returns Method should have no parameters

Question

I have a problem, I would like to pass the test method to send a request using the GET method and POST. I used parameterization, but I get information java.lang.Exception: Method simpleMessage should have no parameters

  @Test
    @ParameterizedTest
    @ValueSource(strings = {"true", "false"})
    public void simpleMessage (boolean isPost) {
        verifyIdOdpEqual(isPost,1243, "message");
    }

I don't quite understand what you trying to achieve as well but you have few problems with your code:

1. By presence of @ParameterizedTest and @ValueSource I assume you using JUnit 5. At the same time looks like you marked your method with annotation from JUnit 4 (because only in that case you will get an exception with the text you quoted).
2. @Test is redundant when the method is annotated with @ParametrizedTest.

You have 2 options how to fix all of the above:

1. If you want to use junit5 then you need to remove @Test annotation and make sure that your tests are launched by a runner that supports JUnit 5 (more info).

   Example:

   package test;
   
   import org.junit.jupiter.params.ParameterizedTest;
   import org.junit.jupiter.params.provider.ValueSource;
   
   public class TestTest {
   
       @ParameterizedTest
       @ValueSource(booleans =  {true, false})
       public void test(boolean data) {
           System.out.println(data);
       }
   }
   

2. If you want to use JUnit 4 then you need to remove @ParameterizedTest and @ValueSource annotations and rewrite your test to use parametrized runner (more info).
