I have this test in my app:

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = ApplicationTestConfig.class)
@MockBeans({ @MockBean(SwaggerConfig.class)})
public class AuthorisationControllerTest implements WebMvcConfigurer {

    private MockMvc mockMvc;

    @Autowired
    private WebApplicationContext wac;


    @Before
    public void setup() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
    }

    @Test
    public void testAuthorisation() throws Exception {
        this.mockMvc.perform(get("/test")).andDo(print()).andExpect(status().isOk())
                .andExpect(content().string(containsString("Hello, World")));
    }


}

but when I run the test I got this error:

Bounty: 50

I have two junit tests which extends an abstract Class

@Configuration
@Profile("test")
public class TestConfig extends SpringBootServletInitializer {
//Config implementations
}
public class abstract TestA {
// common implementation
}
@RunWith(SpringRunner.class)
@SpringBootTest(TestConfig.class)
@WebAppConfiguration
@DirtiesContext
@ActiveProfile("test")
public class TestB extends TestA {
// Tests
}
@RunWith(SpringRunner.class)
@SpringBootTest(TestConfig.class)
@WebAppConfiguration
@DirtiesContext
@ActiveProfile("test")
public class TestC extends TestA {
}

When I run the test classes TestB and TestC following error occurs

#StackBounty: #java #mockito #amazon-dynamodb #junit4 #powermockito DynamoDB put Item is not getting mocked using MockiTo & PowerMock

Bounty: 50

Below is the code which I am trying to Mock,

this.dynamoDb.getTable(PropertyUtil.get(Constants.SOME_TABLE_NAME))
        .putItem(
                new PutItemSpec()
                        .withItem(new Item().withString("ID", pId).withString("eId", pEId)
                                .withString("activeInd", pActiveInd)));

What I have tried is below,

mockStatic(AmazonDynamoDBClientBuilder.class);
    when(AmazonDynamoDBClientBuilder.defaultClient()).thenReturn(Mockito.mock(AmazonDynamoDB.class));
    PowerMockito.mockStatic(PropertyUtil.class);
    when(PropertyUtil.get(Constants.Some__ID_MAPPING_TABLE_NAME)).thenReturn("SOME_TABLE_NAME");
    Table vTable = mock(Table.class);
    PutItemSpec vPutItemSpec = mock(PutItemSpec.class);
    PutItemResult vPutItemResult = new PutItemResult();
    PowerMockito.whenNew(PutItemSpec.class).withAnyArguments().thenReturn(vPutItemSpec);
    PowerMockito.when(vTable.putItem(vPutItemSpec)).thenReturn(vPutItemOutcome);

And the error that I get due to this is below,

java.lang.IllegalArgumentException: null
    at com.amazonaws.services.dynamodbv2.document.PutItemOutcome.<init>(PutItemOutcome.java:33) ~[aws-java-sdk-dynamodb-1.11.400.jar:?]
    at com.amazonaws.services.dynamodbv2.document.internal.PutItemImpl.doPutItem(PutItemImpl.java:86) ~[aws-java-sdk-dynamodb-1.11.400.jar:?]

    at com.amazonaws.services.dynamodbv2.document.Table.putItem(Table.java:168) ~[aws-java-sdk-dynamodb-1.11.400.jar:?]

Please suggest, what I need to fix, I am new to Mock and JUnit.
Thanks in Advance.
