Using Mockito, how do I match against the key-value pair of a map?


Using Mockito, how do I match against the key-value pair of a map?

it helps some times I found this trying to solve a similar issue creating a Mockito stub with a Map parameter. I didn't want to write a custom matcher for the Map in question and then I found a more elegant solution: use the additional matchers in hamcrest-library with mockito's argThat:
code :

mockito refuses to pair TypeSafeMatcher to a generic method API

Does that help As per the documentation (Mockito 1 and Mockito 2), you have to use argThat(matcher), a Mockito matcher which allows you to use your custom argument matchers:
code :
 //stubbing
 when(mock.giveMe(argThat(new MyHamcrestMatcher())));

 //verification
 verify(mock).giveMe(argThat(new MyHamcrestMatcher()));
verify(customPublisher, never()).publish(argThat(isFailureResult()), anyObject());

like below fixes the issue Referred to: SimilarQuestion1, SimilarQuestion2, SimilarQuestion3 , In your case you can use eq with provided filled map:
code :
    when(storedProc.execute(Mockito.eq(givenIncorrectMap)))
            .thenThrow(new Exception(EXCEPTION_NO_IDENTIFIER));
import java.util.Collections;
import java.util.HashMap;
import java.util.Map;

import org.junit.Rule;
import org.junit.Test;
import org.junit.rules.ExpectedException;
import org.mockito.Mockito;

import static org.mockito.Mockito.when;

public class QuestionTest {
    @Rule
    public ExpectedException exception = ExpectedException.none();

    interface A {
        String execute(Map<String, Object> map);
    }

    @Test
    public void test() {
        // Given a map with missed identifiers.
        final Map<String, Object> givenIncorrectMap = new HashMap<>();
        givenIncorrectMap.put("firstIdentifier", null);
        givenIncorrectMap.put("secondIdentifier", null);

        // Given a mocked service
        final A mockedA = Mockito.mock(A.class);

        // which throws an exception exactly for the given map.
        when(mockedA.execute(Mockito.eq(givenIncorrectMap)))
                .thenThrow(new IllegalArgumentException("1"));


        // Now 2 test cases to compare behaviour:


        // When execute with correct map no exception is expected
        mockedA.execute(Collections.singletonMap("firstIdentifier", "any correct value"));

        // When execute with incorrect map the IllegalArgumentException is expected
        exception.expect(IllegalArgumentException.class);
        exception.expectMessage("1");

        mockedA.execute(givenIncorrectMap);
    }
}

this one helps. Assuming you've loaded your json into a map with JsonSlurper, something like
code :
list.each { code ->
    println "$code = " + json.find { it ->
        it.name.contains "($it)"
    }?.id
}

wish helps you adj is of type std::list>*, which is a pointer. Pointers implement the following operator[]

wish help you to fix your issue The sample works if you remove the PowerMock dependencies. The issue is that the versions of Mockito and PowerMock used are incompatible with each other. For PowerMock 2.x you need at least Mockito 2.8.9+. PowerMock provides a compatibility list that shows what version of PowerMock is compatible with what version of Mockito. Fix up the versions to be compatible with each other and your sample will start to work.
