    <p>I have a class <code>FileGenerator</code>, and I'm writing a test for the <code>generateFile()</code> method that should do the following:</p> <p>1) it should call the static method <code>getBlockImpl(FileTypeEnum)</code> on <code>BlockAbstractFactory</code></p> <p>2) it should populate variable <code>blockList</code> from the subclass method <code>getBlocks()</code></p> <p>3) it should call a static method <code>createFile</code> from a final helper class <code>FileHelper</code> passing a String parameter</p> <p>4) it should call the run method of each <code>BlockController</code> in the blockList</p> <p>So far, I have this empty method:</p> <pre><code>public class FileGenerator { // private fields with Getters and Setters public void generateBlocks() { } } </code></pre> <p>I am using JUnit, Mockito to mock objects and I've tried using PowerMockito to mock static and final classes (which Mockito doesn't do).</p> <p>My problem is: my first test (calling method <code>getBlockList()</code> from <code>BlockAbstractFactory</code>) is passing, even though there is no implementation in <code>generateBlocks()</code>. I have implemented the static method in <code>BlockAbstractFactory</code> (returning null, so far), to avoid Eclipse syntax errors.</p> <p>How can I test if the static method is called within <code>fileGerator.generateBlocks()</code>?</p> <p>Here's my Test Class, so far:</p> <pre><code>@RunWith(PowerMockRunner.class) public class testFileGenerator { FileGenerator fileGenerator = new FileGenerator(); @Test public void shouldCallGetBlockList() { fileGenerator.setFileType(FileTypeEnum.SPED_FISCAL); fileGenerator.generateBlocks(); PowerMockito.mockStatic(BlockAbstractFactory.class); PowerMockito.verifyStatic(); BlockAbstractFactory.getBlockImpl(fileGenerator.getFileType()); } } </code></pre>

    2. COThe simplest answer is if you've decided to do TDD, kick the habit of writing static methods :)

    3. CO@ArtB it's a static method from an Abstract class, not an abstract static method. EDIT: just saw the error in my question. Fixed.

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.
