junitparameter exception method should have no parameter
提问by Patrick Lec
By using JUnitParameter for testing a methode I have an exception. My code is similar to lot of example on JUnitParameter:
通过使用 JUnitParameter 测试方法，我有一个例外。我的代码类似于 JUnitParameter 上的很多示例：
private Object parametersForTestSetDistanceFormated() {
return new Object[][]{
{100, "_1,__ km"},
{100, "1_,__ km"},
{1100, "11,__ km"},
{110, "1_,1_ km"},
{111, "1_,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());
}
and then I obtain the following exception:
然后我得到以下异常：

Imports need to be updated like :
进口需要更新，如：
@RunWith(JUnitParamsRunner.class)
public class TestClass {
Now it works
现在它起作用了
回答by Vaibhav Jain
Add @RunWith(JUnitParamsRunner.class) annotation above class as
在类上方添加@RunWith(JUnitParamsRunner.class) 注释作为
import junitparams.JUnitParamsRunner;
Also you need to import
您还需要导入

You are using wrong import for @Parameters- it should be junitparams.Parameters, not org.junit.runners.Parameterized.Parameters
您使用了错误的导入@Parameters- 应该是junitparams.Parameters，而不是org.junit.runners.Parameterized.Parameters
回答by AJC
This error may show up when your test method(having @Test annotation) have any arguments
当您的测试方法（具有 @Test 注释）有任何参数时，可能会出现此错误
For anyone else who came here because of the same error they are seeing but not with JUitParameter.
对于因为同样的错误而来到这里的其他人，他们看到了但不是 JUitParameter。
I hit this same error, in my code.
我在我的代码中遇到了同样的错误。
@Test
void assertResult(String result) {
Assert.assertTrue(!"403".equals(result) && !"404".equals(result) && !"400".equals(result));
Assert.assertNotNull(result);
}
The error was because for a method with argument, I had accidentally added a @Test tag. (Added it when I was testing just that method and then forgot to remove it). Silly me. Worked fine when I removed the @Test. If you want the @Test, then the method shouldn't have any arguments
错误是因为对于带参数的方法，我不小心添加了 @Test 标记。（在我只测试该方法时添加它，然后忘记删除它）。傻我。当我删除@Test 时工作正常。 如果你想要@Test，那么该方法不应该有任何参数
