I am writing my Junit test cases for Groovy using Mockito jar, but it is giving me following exception:

我正在使用 Mockito jar 为 Groovy 编写 Junit 测试用例，但它给了我以下异常：

Below is the jar list that I have:

cglib-nodep-2.2.2
javassist-3.19.0-GA
junit-4.12
mockito-all-1.10.19
objenesis-2.5
powermock-mockito-1.6.2-full

Below is my code. I have added necessary imports:

下面是我的代码。我添加了必要的进口：

package test.service
import org.junit.Test
import org.junit.runner.RunWith
import org.mockito.InjectMocks
import org.mockito.Mock
import org.mockito.junit.MockitoJUnitRunner
import static org.mockito.Mockito.when;

@RunWith(MockitoJUnitRunner.class)
class SyncImplTest {

    @InjectMocks
    SyncThreatImpl  fixture;

    @Mock
    RpcConfigurationLoader rpcConfigurationLoader

    @Test
    public void testRpcConfig(){
        RpcApiInfo rpcApiInfo =  new RpcApiInfo();
        when(rpcConfigurationLoader.loadConfiguration()).thenReturn(rpcApiInfo)
    }


}

For some reason, your test suite, tries to load the MockitoJunitRunnerfrom the org.mockito.junitcontained in the Mockito versions >= 2. O. In that version, the line:

出于某种原因，您的测试套件尝试MockitoJunitRunner从 org.mockito.junitMockito 版本 >= 2. O. 中包含的加载。在该版本中，该行：

at org.mockito.junit.MockitoJUnitRunner.<init>(MockitoJUnitRunner.java:152)

is doing this:

正在这样做：

public MockitoJUnitRunner(Class<?> klass) throws InvocationTargetException {
        //by default, StrictRunner is used. We can change that potentially based on feedback from users
        this(new StrictRunner(new RunnerFactory().createStrict(klass), klass));
    }

and the RunnerFactory that is loaded here is from version 1.x as createStricthas been introduced in Mockito 2.x.

此处加载的 RunnerFactory 来自createStrictMockito 2.x 中引入的1.x 版。

So go through the pom dependency tree and to find what artifact implicitly add the Mockito 2.x dependency to your project and exclude it.

因此，请查看 pom 依赖关系树，找出哪些工件将 Mockito 2.x 依赖项隐式添加到您的项目中并将其排除。

Alternatively.. as a workaround, instead of the @RunWith(MockitoJUnitRunner.class)you can use:

或者......作为一种解决方法，而不是@RunWith(MockitoJUnitRunner.class)您可以使用：

@Before
public void init() {
    MockitoAnnotations.initMocks(this);
}

You can also check out this Mockito cheat sheetto keep all the standards at hand.

In Mockito 1.10.19 (which is from 2014), there is no class org.mockito.junit.MockitoJUnitRunner. This was introduced later in 2.x. If you really want to use 1.10.19, you should probably use the then correct class org.mockito.runners.MockitoJUnitRunnerwhich then should work.

在 Mockito 1.10.19（从 2014 年开始）中，没有 class org.mockito.junit.MockitoJUnitRunner。这是后来在 2.x 中引入的。如果您真的想使用 1.10.19，您可能应该使用org.mockito.runners.MockitoJUnitRunner当时应该可以工作的正确类。

But I would strongly recommend using a newer Mockito version instead. mockito-allis simply not the right artifact to depend on anymore. With 2.x this artefact was not maintained anymore.

但我强烈建议改用较新的 Mockito 版本。mockito-all根本就不再是可以依赖的正确神器。在 2.x 中，这个人工制品不再被维护。

The problem lies within your imports. Your imports doesn't include import runner replace the following import

问题在于您的进口。您的导入不包括导入运行器替换以下导入

org.mockito.junit.MockitoJUnitRunner

with

和

 org.mockito.runners.MockitoJUnitRunner;
