junitparameterexception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_,__ 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()); } 然后我获得以下exception：
java.lang.RuntimeException: java.lang.Exception: Method testSetDistanceFormated should have no parameters at junitparams.JUnitParamsRunner.verifyMethodCanBeRunByStandardRunner(JUnitParamsRunner.java:429) at junitparams.JUnitParamsRunner.runChild(JUnitParamsRunner.java:420) at junitparams.JUnitParamsRunner.runChild(JUnitParamsRunner.java:386) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.apache.maven.surefire.junit4.JUnit4TestSet.execute(JUnit4TestSet.java:53) at org.apache.maven.surefire.junit4.JUnit4Provider.executeTestSet(JUnit4Provider.java:123) at org.apache.maven.surefire.junit4.JUnit4Provider.invoke(JUnit4Provider.java:104) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.maven.surefire.util.ReflectionUtils.invokeMethodWithArray(ReflectionUtils.java:164) at org.apache.maven.surefire.booter.ProviderFactory$ProviderProxy.invoke(ProviderFactory.java:110) at org.apache.maven.surefire.booter.SurefireStarter.invokeProvider(SurefireStarter.java:175) at org.apache.maven.surefire.booter.SurefireStarter.runSuitesInProcessWhenForked(SurefireStarter.java:107) at org.apache.maven.surefire.booter.ForkedBooter.main(ForkedBooter.java:68) Caused by: java.lang.Exception: Method testSetDistanceFormated should have no parameters at org.junit.runners.model.FrameworkMethod.validatePublicVoidNoArg(FrameworkMethod.java:76) at junitparams.JUnitParamsRunner.verifyMethodCanBeRunByStandardRunner(JUnitParamsRunner.java:427) ... 20 more
我没有在网上找到相关内容……
我的全部意见：
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, "_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()); }
在类上面添加@RunWith（JUnitParamsRunner.class）注释
@RunWith(JUnitParamsRunner.class) public class TestClass {
你还需要导入
import junitparams.JUnitParamsRunner;
您对@Parameters使用了错误的导入 – 它应该是junitparams.Parameters ，而不是org.junit.runners.Parameterized.Parameters
当您的测试方法（具有@Test注释）具有任何参数时，可能会出现此错误
对于因为他们看到的相同错误而来到这里的其他人，但不是JUitParameter。
我在我的代码中遇到了同样的错误。

错误是因为对于带参数的方法，我不小心添加了@Test标记。 （当我测试该方法然后忘记删除它时添加它）。 傻我。 删除@Test后工作正常。 如果你想要@Test，那么该方法不应该有任何参数
@Test void assertResult(String result) { Assert.assertTrue(!"403".equals(result) && !"404".equals(result) && !"400".equals(result)); Assert.assertNotNull(result); }
import需要更新如下：
import com.entities.Client; import junitparams.JUnitParamsRunner; import junitparams.Parameters; import static org.junit.Assert.*; import org.junit.Test; import org.junit.runner.RunWith;
现在它有效
