You can not mock that behavior. Because you are initiate your object inside code. You need to inject dependencies via contrutor or somehow. Basically, you need to do dependency injection.
Some mock frameworks (like moq from c#) able to mock only interface or abstract types so you need to inject your dependencies as interface which this is the most common way in general. Some frameworks like mockito/powermock allow to mock concrete types too (powermock also can be able to mock private methods as I remember).
Change your code to work as below :
class YourClass {
private IApiMetricsClient apiMetricClient;
public YourClass(IApiMetricsClient apiMetricClient) {
this.apiMetricClient = apiMetricClient;
}
public [returnType] yourMethod() {
List<JSONObject> metrics = this.apiMetricClient.listApiMetrics(new ApiIdList(apiIds));
// other logics and return data or whatever
}
}

"able to mock only interface or abstract types" Just this part is not true, we can create a mock for a concrete class in Mockito. E.g.Person thing = mock(Person.class);
I've been doing it for ages. But you're right everywhere else!

Somehow I remember it that way, maybe I just to confuse it with moq (from c#) We use it both all the time and switching between languages causes confusings like this one :) I will edit my answer. Thank you.
