我正在使用Mockito jar为Groovy编写我的Junit测试用例，但它给了我以下例外：

java.lang.NoSuchMethodError: org.mockito.internal.runners.RunnerFactory.createStrict(Ljava/lang/Class;)Lorg/mockito/internal/runners/InternalRunner;

以下是我拥有的jar列表：

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

下面是我的代码。我添加了必要的导入：

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)
    }


}

答案 1

由于某种原因，您的测试套件会尝试从 Mockito 版本中包含的 >= 2 加载。O.在该版本中，该行：MockitoJunitRunnerorg.mockito.junit

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

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));
    }

这里加载的RunnerFactory来自Mockito 2.x中引入的1.x版本。createStrict

因此，浏览 pom 依赖项树，找到哪些工件隐式地将 Mockito 2.x 依赖项添加到项目中并将其排除。

或者。。作为解决方法，您可以使用以下命令代替：@RunWith(MockitoJUnitRunner.class)

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

您还可以查看此Mockito备忘单，以保持手头的所有标准。

答案 2

问题出在您的导入中。您的导入不包括导入运行程序替换以下导入

org.mockito.junit.MockitoJUnitRunner

跟

 org.mockito.runners.MockitoJUnitRunner;
