should have no parameters

[neojoda]

I am getting this error when running the dataprovider:

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

I am trying to run it on a grails project.

Test class:

package utils

import org.junit.Before
import org.junit.runner.RunWith
import com.tngtech.java.junit.dataprovider.DataProvider
import com.tngtech.java.junit.dataprovider.DataProviderRunner
import com.tngtech.java.junit.dataprovider.UseDataProvider

/**

• See the API for {@link grails.test.mixin.services.ServiceUnitTestMixin} for usage instructions
  */
  @testfor(ParamsService)
  @RunWith(DataProviderRunner.class)
  class ParamsServiceTests {

  ParamsService service;

  @before
  void setUp() {

  service = new ParamsService();
  

  }

  @dataProvider
  public static Object[][] dataProviderSnumberNotValids() {

  def array = new Object[1][]
  array[0] = ["R09090909"] as Object[];
  return array;
  

  }

  /**

  • method checkValidSNumber

  • when SNumberIsNotValid

  • should returnFalse
    */
    @test
    @UseDataProvider("dataProviderSnumberNotValids")
    public void checkValidSNumber_SNumberIsNotValid_returnFalse(String SNumber) {

    //String sNumber = "def array = new Object[3][]

    Boolean actual = service.checkValidSNumber(SNumber)

    assert (actual instanceof Boolean) //Guard Assertion
    assert !actual
    }

}

Using JUnit 4.10

[neojoda]

I am using grails 2.0.3
It seems that I use eclipse Run as -> Junit Test is working properly, but no when I run grails test-app. It is where I am getting the error.

Thanks for this incredible plugin!

Hi @neojoda,

sorry for the long delay ... unfortunately, this was no problem within the junit-dataprovider. Though, Grails uses a special test runner, see GRAILS-6352. This issue is fixed in version 2.3.:

In order to support alternate JUnit4 test runners, Grails 2.3 no longer uses a
special test runner to run tests [...].

(from http://grails.org/doc/2.3.1/guide/single.html#upgradingFromPreviousVersionsOfGrails, section "Dependency Injection for Integration Tests")

Cheers,
Andreas
