Mockito, Quick solutions

How to solve: mocking chained calls

I have met this issue several times, so I decided to give the simplest solution to you. You have probably had a situation, when you need to return one object, but it demanded mocking each and every object in the middle. You can avoid that by adding parameter to you mocked object like:

@Mock(answer = Answers.RETURNS_DEEP_STUBS)
private Client elasticSearchClient;

private ClusterHealthRequestBuilder healthRequestBuilder;

Currently you can use when() as presented below:


instead of mocking AdminClient, ClusterAdminClient and ClusterHealthRequestBuilder by hand:

ptivate AdminClient admin;
private ClusterAdminClient cluster;
private ClusterHealthRequestBuilder clusterHealthRequestBuilder;

public void setUp() {
