java – junitparameter异常方法应该没有参数

通过使用JUnitParameter来测试方法我有一个例外.我的代码类似于JUnitParameter上的大量示例：

private Object parametersForTestSetDistanceFormated() {
    return new Object[][]{    
        {100,"_1,__ km"},{100,"1_,{1100,"11,{110,1_ km"},{111,11 km"}};
}
/**
 * Test of setDistanceFormated method,of class ClientFormated.
 */
@Test
@Parameters
public void testSetDistanceFormated(final int exptDist,final String  distFormated) {
    System.out.println("setDistanceFormated");
    ClientFormated instance = new ClientFormated();             

    instance.setDistanceFormated(distFormated);
    assertEquals(exptDist,(long) instance.getDistance());
}

然后我获得以下异常：

我没有在网上找到相关内容……

我的全体意见：

import com.entities.Client;
import junitparams.JUnitParamsRunner;
import org.junit.Test;
import static org.junit.Assert.*;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized.Parameters;

@RunWith(JUnitParamsRunner.class)
public class ClientFormatedTest {

private Object parametersForTestSetDistanceFormated() {
    return new Object[][]{    
        {100,11 km"}};
}

/**
 * Test of setDistanceFormated method,(long) instance.getDistance());
}

解决方法

@RunWith(JUnitParamsRunner.class)
public class TestClass {

你还需要导入

import junitparams.JUnitParamsRunner;
