| <h1> |
| Using content assist |
| </h1> |
| <p> |
| In this section you will use <em>content assist</em> to finish writing a new |
| method. Open <em>junit.samples.VectorTest.java</em> file in the Java |
| editor if you do not already have it open and select the <code>testSizeIsThree()</code> method |
| in the Outline view. If the file doesn't contain such a method see <a href="qs-AddMethod.htm">Adding new methods</a> |
| for instructions on how to add this method. |
| </p> |
| <ol> |
| <li> |
| Add the following lines to the end of the method: |
| <p> |
| <code> |
| Vector v = new Vector();<br> |
| for (int i=0; i<3; i++)<br> |
| v.addElement(new Object());<br> |
| assert<br> |
| </code> |
| </p> |
| </li> |
| <li> |
| With your cursor at the end of the word <code>assert</code>, press <kbd>Ctrl</kbd>+<kbd>Space</kbd> to activate content assist. The content assist window with a list of |
| proposals will appear. Scroll the list to see the available choices. |
| <p> |

| </p> |
| </li> |
| <li> |
| With the content assist window still active, type the letter 't' |
| in the source code after <code>assert</code> (with no space in between). The list is narrowed and only shows entries |
| starting with 'assertt'. Select and then hover over various items in the list to view any available Javadoc help for each item. |
| <p> |

| </p> |
| </li> |
| <li> |
| Select <code>assertTrue(boolean)</code> from the list and press <kbd>Enter</kbd>. The code for the <code>assertTrue(boolean)</code> method is inserted. |
| </li> |
| <li> |
| Complete the line so that it reads as follows:<br> |
| <p><code> |
| assertTrue(v.size() == fFull.size()); |
| </code></p> |
| </li> |
| <li> |
| Save the file. |
| </li> |
| </ol> |
