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

Question

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

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

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:

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)
    }


}

Answer 1

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

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

is doing this:

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 createStrict has been introduced in Mockito 2.x.

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.

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

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

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

Answer 2

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

org.mockito.junit.MockitoJUnitRunner

with

 org.mockito.runners.MockitoJUnitRunner;

Answer 3

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.MockitoJUnitRunner which then should work.

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