Wanted but not invoked: Mockito and Powermock - java

I have a Junit test that I inherited that is no longer working. It is using PowerMock 1.4.12, Mockito 1.9.0 and Junit 4.8.2. It was working awhile back but stopped and I am trying to get it to work again.
Wanted but not invoked:
clerkReviewPackageHelper.addSubmissionQueue(
<any>,
<any>,
<any>,
<any>
);
-> at icis.cr.approvefilingdetail.CRFilingToQueuesActionTest.test_post_handled_add_submission_queue(CRFilingToQueuesActionTest.java:47)
Actually, there were zero interactions with this mock.

Here is the code for this test:
#Test
public void test_post_handled_add_submission_queue() throws Exception {
when(request.getMethod()).thenReturn(BaseCRAction.POST);
when(sessionInfo.getSubmissionId()).thenReturn(SUBMISSION_ID);
when(crFilingToQueuesForm.getAction()).thenReturn(null);
crFilingToQueuesAction.executeProcess(actionMapping, crFilingToQueuesForm, request, response);
verify(clerkReviewPackageHelper, times(0)).removeSubmissionQueue(null);
**verify(clerkReviewPackageHelper).addSubmissionQueue(any(String.class), any(String.class), any(String.class), any(String.class));**
verify(actionMapping).findForward(eq(BaseCRAction.FORWARD_SUCCESS_REDIRECT));
}
And this is the method that it calls from the line in the exception:
public void addSubmissionQueue(String submissionId, String queueId, String reviewOn, String employeeId) throws BadDBConnection {
Session session = injector.inject();
session.executeNonSelectingCall(clerkReviewPackage.addQueue(submissionId, queueId, reviewOn, employeeId));
session.release();
}
Any help would be appreciated!
Thanks,
Tom

It looks like executeProcess used to call addSubmissionQueue but doesn't anymore, but without the code of executeProcess it's hard to say for sure.
If it's appropriate not to call addSubmissionQueue, you can simply delete the reference to that verification line. If it is important to call it, or call it under specific circumstances, edit the test so the verify line only happens in test cases where a call to that method is required.
Note that because Mockito is involved, your test isn't calling the actual code for addSubmissionQueue, but a mock instead. Read more about how Mockito works in the examples on the Mockito homepage.

Try :
import org.mockito.Mockito;
// ...
Mockito.verify(clerkReviewPackageHelper, Mockito.times(0)).addSubmissionQueue();

Your clerkReviewPackageHelper mock doesn't seem to be associated with your call to executeProcess in any way. It's not passed in, and it doesn't seem to be returned, directly or indirectly, from any method calls on any mocks that are passed in to executeProcess. It therefore hardly seems reasonable to expect one of its methods to get called by executeProcess.
What you need to do is look through the call to executeProcess and find the object, if any, on which addSubmissionQueue is called. Without seeing the code for executeProcess, I can't really offer assistance with this. It may be but there is no such method call, as #JeffBowman has conjectured in his answer. But there are also other possibilities.
If the object on which addSubmissionQueue is called is one of the parameters to executeProcess, then you should use clerkReviewPackageHelper as the corresponding argument in the test.
If the object on which addSubmissionQueue is called is an a field in the one of the parameters to the executeProcess, then inject clerkReviewPackageHelper, either in the constructor of crFilingToQueuesAction, or a setter, or even with #InjectMocks.
If the object on which addSubmissionQueue is called is obtained from a method call on one of the other parameters to executeProcess, then you need to make that call return clerkReviewPackageHelper. This might mean injecting that value into some object, or it might mean stubbing a method call on a mock. For example, if the method that you're testing obtains clerkReviewPackageHelper by calling a line like crFilingToQueuesForm.getHelper(), then you need to write when(crFilingToQueuesForm.getHelper()).thenReturn(clerkReviewPackageHelper); or something similar. It may turn out to be more complex than this of course. I can't tell without seeing your code.
If you need more help, then please post the code of your executeProcess method.

I also faced this issue while writing testcase for my controller method,what i missed is am passing the parameters to my test method those are declared but not initialized inside the setup method, so i did them in setup method and the issue fixed.

UnfinishedVerificationException when verfying with Mockito.never() [duplicate]

Mockito appears to be throwing an UnfinishedVerificationException when I think I've done everything correctly. Here's my partial test case:
HttpServletRequest req = mock(HttpServletRequest.class);
when(req.getHeader("Authorization")).thenReturn("foo");
HttpServletResponse res = mock(HttpServletResponse.class);
classUnderTest.doMethod(req, res); // Use the mock
verify(res, never());
verify(req).setAttribute(anyString(), anyObject());
And here's the partial class and method:
class ClassUnderTest extends AnotherClass {
#Override
public String doMethod(ServletRequest req, ServletRequest res) {
// etc.
return "someString";
}
}
Ignoring the fact that you should never mock interfaces you don't own, why is Mockito giving me the following message?
org.mockito.exceptions.misusing.UnfinishedVerificationException:
Missing method call for verify(mock) here:
-> at (redacted)
Example of correct verification:
verify(mock).doSomething()
Also, this error might show up because you verify either of: final/private/equals()/hashCode() methods.
Those methods *cannot* be stubbed/verified.

This might also be caused if you try to verify a method which expects primitive arguments with any():
For example, if our method has this signature:
method(long l, String s);
And you try to verify it like this, it will fail with aforementioned message:
verify(service).method(any(), anyString());
Change it to anyLong() and it will work:
verify(service).method(anyLong(), anyString());
I just came across this my self and it caused me a lot of confusion.
As David mentioned above Mockito reports errors in the next Mockito method call which may not be in the same test method. While the exception message does contain a reference to the actual place the error occurred I find having incorrect tests failing counter productive to the testing process. And the simpler the tests the more likely an error is to show up in the next test!
Here is an easy fix that will ensure errors appear in the correct test method:
#After
public void validate() {
validateMockitoUsage();
}
From the Mockito documentation here:
Mockito throws exceptions if you misuse it so that you know if your
tests are written correctly. The gotcha is that Mockito does the
validation next time you use the framework (e.g. next time you verify,
stub, call mock etc.). But even though the exception might be thrown
in the next test, the exception message contains a navigable stack
trace element with location of the defect. Hence you can click and
find the place where Mockito was misused.
Sometimes though, you might
want to validate the framework usage explicitly. For example, one of
the users wanted to put validateMockitoUsage() in his #After method so
that he knows immediately when he misused Mockito. Without it, he
would have known about it not sooner than next time he used the
framework. One more benefit of having validateMockitoUsage() in #After
is that jUnit runner will always fail in the test method with defect
whereas ordinary 'next-time' validation might fail the next test
method. But even though JUnit might report next test as red, don't
worry about it and just click at navigable stack trace element in the
exception message to instantly locate the place where you misused
mockito.
I was getting this same error due to using any() with a boolean parameter, when apparently it needed to be anyBoolean().
In my case, using kotlin was because the funcion to test was not declared as open.
The exception notices that no final/private/equals/hash methods can be used.
fun increment(){
i++
}
to
open fun increment(){
i++
}
With Junit 5, you can add the following to show more meaningful Mockito exceptions in the console
#AfterEach
public void validate() {
validateMockitoUsage()
}
Also see this answer: https://stackoverflow.com/a/22550055/8073652
I had similar exception with class MyRepository
org.mockito.exceptions.misusing.UnfinishedVerificationException:
Missing method call for verify(mock) here:
-> at MyRepository$$FastClassBySpringCGLIB$$de8d8358.invoke()
Example of correct verification:
verify(mock).doSomething()
The problem was resolved when I created interface for MyRepository, and mock interface, but not implementation.
It seems spring creates some CGLIB proxies and it leads to UnfinishedVerificationException exception.
For me the issue turned out to be a missing bean declaration in the test context xml. It was for a custom aspect class used by another class, an instance of which is a parameter to the constructor of the class which is the parameter to failing verify() call. So I added the bean declaration to the context xml and it worked fine after that.
Changed to #RunWith(PowerMockRunner.class) and the issue went away.
Was using #RunWith(MockitoJUnitRunner.class) earlier.
Hope that helps someone..
I had the same issue, too, on the following stack:
Kotlin
Junit 4.13
Mockito 2.28.2 + Mockito-Inline 2.13.0
Robolectric 4.3.1
I tried to verify a lambda call:
#RunWith(RobolectricTestRunner::class)
class MainViewTest {
#get:Rule
val mockitoRule: MockitoRule = MockitoJUnit.rule()
#Mock private lateinit var mockClickCallback: () -> Unit
#Test
fun `should call clickCallback on the button click`() {
val activity = Robolectric.buildActivity(MainActivity::class.java).create().get()
val viewUnderTest = MainView(activity)
viewUnderTest.setClickCallback(mockClickCallback)
viewUnderTest.button.performClick()
verify(mockClickCallback).invoke() // UnfinishedVerificationException
}
}
Then I found the issue on Github, it seems that the problem is in Robolectric. I used the following workaround:
#RunWith(RobolectricTestRunner::class)
class MainViewTest {
private interface UnitFunction: () -> Unit
#Test
fun `should call clickCallback on the button click`() {
val activity = Robolectric.buildActivity(MainActivity::class.java).create().get()
val viewUnderTest = MainView(activity)
val mockClickCallback = mock(UnitFunction::class.java) as () -> Unit
viewUnderTest.setClickCallback(mockClickCallback)
viewUnderTest.button.performClick()
verify(mockClickCallback).invoke() // OK
}
}
Two answers above suggested using validateMockitoUsage() method after each test.
While this is correct I found that annotating your class with #ExtendWith(MockitoExtension.class)
in Junit 5 give the same effect while adding some the nice Mockito functionalities. Also, it looks cleaner to me as well.
I guess Junit 4 #RunWith(MockitoJUnitRunner.class) will give a similar result but I didn't test it.
I had a similar problem, i found a way to solve this. Mock objects which you for verify haven't been reseted, so you should reset it .You can reset(mock) before your test case function, it may be helpful.
If you try to verify a private or package-private method with Mockito.verify you will get this error.
If you don't want to use PowerMockito you can set your method as protected and I advise you to add the #VisibleForTesting tag:
Before:
void doSomething() {
//Some behaviour
}
After :
#VisibleForTesting
protected void doSomething() {
//Some behaviour
}
I was having the same error
org.mockito.exceptions.misusing.UnfinishedVerificationException:
Missing method call for verify(mock) here:
-at com.xxx.MyTest.testRun_Should_xxx_When_yyy(MyTest.java:127)
Example of correct verification:

Also, this error might show up because you verify either of: final/private/equals()/hashCode() methods.
Those methods *cannot* be stubbed/verified.

In my case, the error was generated because I was using a PowerMockito.verifyStatic() before my Mockito.verify(...) call, then I had to move the PowerMockito.verifyStatic() to last line (or delete it).
From:
PowerMockito.verifyStatic();
Mockito.verify(myMock, Mockito.times(1)).myMockedMethod(anyString(), anyString(), anyString(), any(XXX.class), any(YYY.class), any(ZZZ.class));
To:
Mockito.verify(myMock, Mockito.times(1)).myMockedMethod(anyString(), anyString(), anyString(), any(XXX.class), any(YYY.class), any(ZZZ.class));
PowerMockito.verifyStatic();
Here is my grain of salt!
I discovered there is a conflict between Mockito and Hibernate Validation.
My solution is the separate my contract checks (#NotNull, #NotEmpty, etc) from the mockito tests. I also started using validateMockitoUsage() to ensure everything was run correctly.
The tests run individually well but while running integration test suite it fails with the UnfinishedVerificationException. The issue arises when we use verify() from mockito and have #EnableRetry.
Workaround for this is to use
public static <T> T unwrapAndVerify(T mock, VerificationMode mode) {
return ((T) Mockito.verify(AopTestUtils.getTargetObject(mock), mode));
}
as mentioned in Mocked Spring #Service that has #Retryable annotations on methods fails with UnfinishedVerificationException
I'm not sure where are your "classUnderTest" come from, but please keep sure it's mocked, not a real one.
I have the same issue for my test case below:
MyAgent rpc = new MyAgent("myNodeName");
...
rpc.doSomething();
...
PowerMockito.verifyPrivate(rpc).invoke("initPowerSwitch");
PowerMockito.verifyPrivate(rpc).invoke("init", "192.168.0.23", "b2", 3);
But it's disappeared for the following test case:
MyAgent rpc = PowerMockito.spy(new MyAgent("myNodeName"));
...
rpc.doSomething();
...
PowerMockito.verifyPrivate(rpc).invoke("initPowerSwitch");
PowerMockito.verifyPrivate(rpc).invoke("init", "192.168.0.23", "b2", 3);
Attention, the Object rpc should be mocked by PowerMockito.spy(...).
Faced same exception when used mockStatic method and called Mockito.verify multiple times, but passed interface instead of implementing class.
wrong code:
try (MockedStatic<Service> staticMock = Mockito.mockStatic(Service.class, Mockito.CALLS_REAL_METHODS)) {
staticMock.verify(() -> ServiceImpl.method()); // passed without errors
staticMock.verify(() -> ServiceImpl.method()); // throws UnfinishedVerificationException
}
fixed code:
try (MockedStatic<ServiceImpl> staticMock = Mockito.mockStatic(Service.class, Mockito.CALLS_REAL_METHODS)) {
staticMock.verify(() -> ServiceImpl.method());
staticMock.verify(() -> ServiceImpl.method());
}
It was my mistake obviosly, but UnfinishedVerificationException message was not helpfull

Do I always need `when/thenReturn` for mock object's functions

I am writing a test in Scala where I do something like this --
val svc = mock[Service]
Initializer.fun1(svc)
fun1 internally calls a function svc.fun2 which returns Unit.
My test is failing when it tries to execute svc.fun2 with this error -
java.lang.NoSuchMethodError: org.mockito.internal.invocation.ArgumentsProcessor.expandArgs
As svc has already been mocked, I shouldn't have to mock fun2 ,right ?
Unless I want fun2 to return a specific value
Same thing worked for another codebase of mine, but that's using a different library for Mockito
Update :
I also tried adding a when/thenReturn for fun2 but still getting the same error.
I just did this
when(svc.fun2()) thenReturn()
since it's supposed to return UNIT

EasyMock missing behavior even though it's defined

No matter what I do, I get the following error when trying to mock a method
java.lang.IllegalStateException: missing behavior definition for the preceding method call:
ConfigurationSection.get("country-language")
Usage is: expect(a.foo()).andXXX()
My code for testing:
EasyMock.expect(section.getString("country-language")).andReturn("US");
LocaleManager.updateLocale(section, Collections.emptyList());
EasyMock.expectLastCall();
replayAll();
Assert.assertEquals("Test", TranslatedMessage.translate("test"));
verifyAll();
The expect andReturn is called for the mocked class, and the static upateLocale method calls the method, first thing.
The strange thing is this test works fine:
EasyMock.expect(section.getString("country-language")).andReturn("US");
replayAll();
Assert.assertEquals("US", section.getString("country-language"));
verifyAll();
But calling it from an external method doesn't work.
Your mock says:
EasyMock.expect(section.getString("country-language"))
The error says:
ConfigurationSection.get("country-language")
You are not mocking get("country-language"). You are mocking getString("country-language").
Unrelated, but verify is a maintenance nightmare and should generally be avoided. This ties test code directly to an implementation. Tests should focus on inputs and outputs if at all possible.

Not a direct solution, but a reasonable workaround: I assume, you want to use PowerMock to test your code, that has to make this static call, to then use the result coming back from it.
So, instead of "directly" making this static call, you create a wrapper around this functionality, like:
interface ConnectionProvider {
public HConneciotn createConnection(configuration);
and a corresponding class that implements that method (by actually makes the static call).
Now you can change your other production code to work with your that new interface; and now, all your client code can be tested without the need to user PowerMokito ... because there is no more static call.
Of course, you might want to use PowerMokito to ensure that your new wrapper implementation is doing exactly what you expect it to do.
Use #SuppressStaticInitializationFor("org.apache.hadoop.conf.CoreDefaultProperties") to suppress static initialisation of the org.apache.hadoop.conf.CoreDefaultPropertiesclass. More information you may find in PowerMock documentation.
If you've just started write your application then, the better way will be create a class wrapper which will encapsulate static call and the wrapper in your system. There is a good principal: don't mock what you don't own.
And for the wrapper you may write an integration test that will test that wrapper works as you expected and you system expected.

EasyMock JUnit testing throws error on the setter method

I am using easyMock for JUnit testing. I want to test a method which gets a Project object as its arguments and sets the modify date of that project and persists it in db.
So e.g.
public void setProject(Project project) {
project.setModifyDate(new Date());
this.reporsitory.persist(project);
}
Now at my test method I have tow mocked projects. For one of them I have set the return value of the getModifyDate. For the other mocked project object I just call the setProject(mockedProject); Now I assertEqual these two project objects.
The problem is easymock throws me an error at the project.setModifyDate(new Date()) of the class which I am testing.
Exception : Unexpected method call project.setModifyDate(..).. Expected:1, Actual:0.
It seems that it does not expect the setter method. Could you please let me know what I am doing wrong.
Thanks.
Yes, it is because of the type of mock object you created. It expects your code to call every method you defined when the one call executes. I cannot remember the exact name but i think it is something like nicemock, versus a strictmock whick makes your code execute every expected method. You should use EasyMock.createNiceMock() for your mock object. The error you have is because it expects you to call setModifyDate but your code didn't for that call.
Your call is unexpected because you must have not put EasyMock.expected for that method. You need to add your mock object .expected(getMethod).andReturns(something).
