    <p>I think the first improvement would be to use this: </p> <pre><code>when(methodA()).thenReturn(linkedListA.get(0), linkedListA.get(1), linkedListA.get(2)) and so on </code></pre> <p>Moreover, you could you the <code>thenAnswer</code> method to return a value:</p> <pre><code>final AtomicInteger i = new AtomicInteger(0); when(methodA()).thenAnswer(new Answer&lt;YourType&gt;() { @Override public YourType answer(InvocationOnMock invocation) { return linkedListA.get(i.getAndIncrement()); } }); </code></pre> <p>Example:</p> <pre><code>import static org.powermock.api.mockito.PowerMockito.when; import java.util.Arrays; import java.util.List; import java.util.concurrent.atomic.AtomicInteger; import org.junit.Test; import org.junit.runner.RunWith; import org.mockito.Mock; import org.mockito.invocation.InvocationOnMock; import org.mockito.stubbing.Answer; import org.powermock.api.mockito.PowerMockito; import org.powermock.core.classloader.annotations.PrepareForTest; import org.powermock.modules.junit4.PowerMockRunner; @RunWith(PowerMockRunner.class) @PrepareForTest(Blub.class) public class Mockexample { @Test public void test() { Blub blub = PowerMockito.mock(Blub.class); final List&lt;Integer&gt; counter = Arrays.asList(1, 2, 3); final AtomicInteger i = new AtomicInteger(0); // blub.size() is final, only reason to use PowerMockito here when(blub.size()).thenAnswer(new Answer&lt;Integer&gt;() { @Override public Integer answer(InvocationOnMock invocation) throws Throwable { return counter.get(i.getAndIncrement()); } }); System.out.println(blub.size()); System.out.println(blub.size()); System.out.println(blub.size()); } } </code></pre> <p>The Blub clas:</p> <pre><code>public class Blub { public final int size() { return 0; } } </code></pre>

    2. CO@TimeToCodeTheRoad sorry if I have not been clear, you need also the Mockito library in your classpath to make the example run.

    3. COi gave you full credit for this answer :D. May I ask another quick question about the same. Why does the following not work: int k=-1; when(blub.size()).thenReturn(counter.get(++k)) . thanks!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
