What this exeception is telling you...
You haven't provided the instance at field declaration
In other words, you did not write...
@InjectMocks
A a = new A("foobar", 123);
This would be completely acceptable and will probably solve your problem. Please remember that mocks will NOT be initialized at that point, so it's fine if you really need an example String
and int
there, but not if you need to put mocks there. In other words, if you had a constructor that took an X and you would write new A(x)
here, x would be null, since the @Mock
annotation would not have been processed yet.
so I tried to construct the instance
Because there was no instance (because you didn't provide one) it tried to create one, but...
However, the constructor or the initialization block threw an exception: null
So, your constructor throws null. Seems like your someMethodCall
relies on the arguments (port, most likely) given not to be null, but since they are String
and int
, Mockito has no idea what values to use there. Since port
is a primitive type and Mockito does not handle those specifically, the problem is probably there - Mockito will try to put null there, which will throw an exception.
If your constructor matched X and Y, for example, Mockito would probably try to put the mocks there, but it doesn't. The constructor wants String
and int
and there are no mocks for them, so Mockito can only use default values and those are null
, which is a problem in case of port
(because of int
).
So, what's the solution?
1) Either make your constructor null-safe, allowing to give a null-port there (and make sure that the ip string is also handled in a null-safe way).
2) Use the thing you didn't use:
@InjectMocks
A a = new A("foobar", 123);
In any case, it is not required to have all the depedencies in the constructor, Mockito will do fine injecting them into fields directly. So adding another constructor for X and Y is not a real solution. Of course, generally, constructor injection is preferable over field injection, but that's another topic.
As for your question about which constructor: The documentation says this...
the biggest constructor is chosen, then arguments are resolved with mocks declared in the test only
Edit: Seems that Mockito does not know how to handle primitive fields in constructors, what a shame.

I routinely come across test strategy documents when working with customers. They are lengthy—100 pages or more—and packed with monotonous text that is routinely reused from one project to another. Yawn once more— the test halt and resume circumstances, the defect management procedure, entrance and exit criteria, unnecessary generic risks, and in fact, one often-used model replicates the requirements of textbook testing, from stress to systems integration.
Websites and web apps are growing in number day by day, and so are the expectations of people for a pleasant web experience. Even though the World Wide Web (WWW) was invented only in 1989 (32 years back), this technology has revolutionized the world we know back then. The best part is that it has made life easier for us. You no longer have to stand in long queues to pay your bills. You can get that done within a few minutes by visiting their website, web app, or mobile app.
QA testers have a unique role and responsibility to serve the customer. Serving the customer in software testing means protecting customers from application defects, failures, and perceived failures from missing or misunderstood requirements. Testing for known requirements based on documentation or discussion is the core of the testing profession. One unique way QA testers can both differentiate themselves and be innovative occurs when senseshaping is used to improve the application user experience.
It’s strange to hear someone declare, “This can’t be tested.” In reply, I contend that everything can be tested. However, one must be pleased with the outcome of testing, which might include failure, financial loss, or personal injury. Could anything be tested when a claim is made with this understanding?
Greetings folks! With the new year finally upon us, we’re excited to announce a collection of brand-new product updates. At LambdaTest, we strive to provide you with a comprehensive test orchestration and execution platform to ensure the ultimate web and mobile experience.
