    <p>My understanding of <a href="https://code.google.com/p/jmockit/" rel="nofollow">JMockit</a> is that it will replace all instances of a mocked object with a mock (unless you tell it otherwise).</p> <p>Hence I am perplexed to be getting a <a href="http://download.oracle.com/javase/6/docs/api/index.html?java/lang/NullPointerException.html" rel="nofollow">NPE</a> after instantiating an object I'm attempting to mock.</p> <p>The purpose of the test is not to investigate the object causing the NPE, but I do need to mock it in order to carry out the test as it carrys out some database actions to validate some input.</p> <p>My code under test is like this (not copy pasta, as it's work code, but should highlight the issue nonetheless):</p> <pre><code>public class ClassToTest{ public execute(){ MyDependency myDep = getDependency(); myDep.doSomething(); //I get a NPE here, implying getDependency returned null } protected MyDependency getDependency(){ return new MyDependency("an Arg", "another Arg"); } } </code></pre> <p>My Test method:</p> <pre><code>@Test public void testCreateHorseDogMeetingByCodeDataProviderTruncated() throws IllegalArgumentException, SQLException, IllegalCountryLocationCombo, MEPException { // Arrange ClassToTest myClass = new ClassToTest(); new NonStrictExpectations() { MyDependency mockDep; { //Set up my expectations, not related to MyDependency } }; // Act myClass.execute(); // Assert new Verifications() { { //some verification stuff } }; } </code></pre> <p><strong>Can anyone help me fix this NPE issue so I can finish my test?</strong></p>

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.
