<!-- ============================================= -->
<p>
This tutorial introduces you to the JT harness version 4.4.1 GUI and some
basic underlying concepts. The tutorial instructions have you run a
very simple test suite called Demo Test Suite that is included in the
<code>examples</code> directory. Demo Test Suite contains 17 tests that test the
functionality of some very simple demo APIs.
</p>
<p>
This tutorial describes how to:
</p>
<ul>
<li><A HREF="#start">Start the JT harness</A></li>
<li><A HREF="#wizard">Use the Quick Start wizard</A></li>
<li><A HREF="#config">Configure test information</A></li>
<li><A HREF="#run">Run the test suite</A></li>
<li><A HREF="#browse">Browse the test results</A></li>
<li><A HREF="#exclude">Exclude a failed test</A></li>
<li><A HREF="#generate">Generate a Report</A></li>
</ul>
<p>
The tutorial should be run using version 6.0 (or later) of the Java&#153; Platform, Standard Edition (Java SE) on either the
Microsoft Windows (Win32) platforms, or on the Solaris&#153; Operating
System.
</p>
<p>
<b>NOTE: </b>Unless otherwise indicated, all examples in this book use
UNIX style command prompts and file separators.
</p>
<p>
To keep things simple, these instructions show you how to run both the
JT harness and the tests on the same system in different virtual machines for the
Java platform (JVM&#153; machines). The following diagram illustrates
this:
</p>

</p>
<!-- ============================================= -->
<A NAME="start"></A>
<hr align="left" noshade size="5" width="100">
<h2>Start the JT Harness</h2>

<ol>
<li>
<b>Verify that Java SE version 6.0 (or later) is in your path.</b>
<p>At a command prompt, enter:</p>
<p><dl><dd><code>java -version</code></dd></dl></p>
</li>

<li>
<b>Make</b> <i>jt_install</i><code>examples/demots</code>
<b>the current directory.</b>
<p>
The directory <i>jt_install</i> is the directory into which you installed the
JT harness software.
</p>
</li>

<li>
<b>Start the JT harness.</b>
<p>
At a command prompt enter:
</p>
<dl>
<dd>
<code>java -jar lib/javatest.jar -newDesktop</code>
</dd>
</dl>
<p>
<b>Note: </b>The <code>-newDesktop</code> option is used here to
ensure that the JT harness starts up exactly as described in
these instructions. Under normal circumstances you should <i>not</i> use
this option because you will lose information that the harness saved
about your previous session. For information about JT harness options,
see the JT harness online help.
</p>
</li>
</ol>

<p>
The JT harness  starts and displays the Quick Start wizard window:

<p>
<br>
</p>
<!-- ============================================= -->
<A NAME="wizard"></A>
<hr align="left" noshade size="5" width="100">
<h2>Quick Start Wizard</h2>
<p>
The Quick Start wizard leads you through the basic steps required to
start running the test suite.
</p>
<ol>
<li>
<b>Panel 1: Welcome to the JT Harness</b>
<p>
Choose "Start a new test run", and click Next
</p>
</li>
<li>
<b>Panel 2: Test Suite</b>
<p>
Click the Next button (accept the default).
</p>
</li><li>
<b>Panel 3: Configuration</b>
<p>
Choose "Create a new configuration", and click Next
</p>

<li>
<b>Panel 4: Work Directory</b>
<p>
The JT harness uses the work directory to store information and
to write test results. Click the Browse button to activate a file
chooser. Use the file chooser to create a work directory. Be sure to
create the work directory in a convenient location <i>outside of the test
suite directory</i> (<code>demots</code>). Click Next.
</p>
</li>
<li>
<b>Panel 5: Almost Done ...</b>
<p>
Click the Finish button to complete the Quick Start process.
The configuration editor window starts automatically.
</p>
</li>
</ol>
<p>
<br>
</p>
<!-- ============================================= -->
<A NAME="config"></A>
<hr align="left" noshade size="5" width="100">
<h2>Configure the Test Information</h2>
<p>
Because the "Start the configuration editor" checkbox was checked in
the last panel of the Quick Start wizard, the configuration editor
starts automatically.
</p>
<p>
You use the configuration editor to configure the information required
to run the test suite. As shown below, the configuration editor
consists of three panes and a menu bar:
</p>
<IMG SRC="images/confEditorFull.gif">
<p>
<b>Figure 3:&nbsp;&nbsp; </b>JT Harness Configuration Editor
</p>
<p>
The left pane lists the titles of the questions you have answered, are
currently answering, or that the editor deduces must be answered. The
current question is highlighted.
</p>
<p>
The center pane displays the interview questions. You answer the
questions by using controls such as text boxes, radio buttons, or
combo boxes located below each question. Whenever possible, the editor
deduces answers from your system configuration and includes them in
text boxes, combo boxes, and radio buttons. You can accept these
answers or provide other answers.
</p>
<p>
The right pane displays important information about each question, such as:
<ul>
<li>Background information</li>
<li>Examples of answers</li>
<li>Additional information about choosing an answer</li>
</ul>

<h3>Answer the Questions in the Configuration Editor</h3
><p>
The following table presents the titles, answers, and information
about each question that you must answer in the interview. There are
13 questions in the Demo Test Suite interview.

<h2>Run Tests</h2>
<ol>
<li>
<b>Set the view filter to Last Test Run.</b>
<p>
Choose "Last Test Run" in the View Filter combo box located in the
tool bar. This changes your "view" of the test tree so that you only
see the results of the current test run. This is generally the view
that most users prefer to begin with.
</p>
<p>
<b>Note:</b> When you change to the Last Run filter before you do a
test run, the folders and tests in the tree turn to gray indicating
that they are filtered out. This occurs because there are currently no
results from a "last test run".
</p>
</li>

<li>
<b>Choose Run Tests > Start to start the test run.</b>
<p>
The test suite should begin to run. You will see activity in the test
tree panel that indicates which tests are running. You can also watch
the progress of the test run in the progress monitor on the
bottom-right portion of the JT harness window and the pie chart
in the Summary tab.
</p>
</li>

<li>
<b>Expand the test tree folders to reveal the tests.</b>

Now that the test run is complete, you will use the Folder tabbed pane
and Test tabbed pane portion of the JT harness to examine the
results. You will also examine the output of the test that failed.
<p>
<b>Note: </b>The Folder tabbed pane and the Test tabbed pane occupy
the same portion of the Test Manager window. The Folder tabbed pane is
displayed when you choose a folder entry in the test tree and the Test
tabbed pane is displayed when you choose a test entry in the test
tree.

<h2>Exclude a Failed Test</h2>
<p>
The JT harness allows you to "exclude" tests from a test suite
by specifying an <i>exclude list</i> file. This section shows you how
to use the quick set mode of the configuration editor window to
specify an exclude list that includes
<code>lists/DoublyLinkedList/InsertTest.java</code>. Tests that are
excluded are not executed during test runs, and though they are still
displayed in the test tree, their status is not reflected in the
pass/fail status of the test suite.
<ol>
<li>
<b>Choose Configure > Edit Configuration > Exclude List
from the test manager menu bar.</b>
<p>
The configuration editor window opens directly to a panel that allows
you to specify an exclude list. This quick set mode allows you to
quickly change values that change frequently between test runs. These
values are also referred to as <i>standard values</i>. Note that
standard values can also be changed using the configuration editor
window in question mode.
</p>
</li>

<li>
<b>In the Exclude List pane, click Other.</b>
<p>
This activates a tool with which you can specify a set of exclude lists.
</p>
</li>

<li>
<b>Click the Add button on the upper right portion of the tool.</b>
<p>
This invokes a file chooser with which you can specify an exclude
list. The current directory of the file chooser should be the
directory in which you started the JT harness. If it is not,
please navigate to that directory.
</p>
</li>

<li>
<p><b>Double-click on the</b> <code>lib</code> <b>directory entry in the file chooser.</b></p>
</li>

<li>
<b>Choose the</b> <code>demo.jtx</code> <b>entry in the file chooser and click Select.</b>
<p>
Notice that the exclude list (<code>demo.jtx</code>) is added to the Exclude Lists
text box.
</p>
</li>

<li>
<p><b>Click Done in the configuration editor.</b>
</p>
</li>

<li>
<b>Change the view filter to "Current Configuration".</b>
<p>
The Current Configuration filter shows which tests are selected and
filtered out in the configuration, in effect a filter that shows which
tests <i>will be</i> run next, as opposed to the Last Test Run filter which
shows the tests that <i>were</i> run.
</p>
<p>
Notice that the icon for the for <code>InsertTest.java</code> entry in
the Test tree changes from red to gray. This indicates that the test
has been filtered out and will not be executed. Also notice that the
Test Suite Root folder has changed from red to green, indicating that
all the currently selected tests have passed.
</p>
</li>
</ol>

<h2>Generate a Report</h2>
<p>
You can use the JT harness to generate an HTML report that
describes the results of the test run. All of the information
contained in the report is available from the GUI; however, the
following steps describe how to generate and browse a report that
describes the test run done in the previous sections of this tutorial.
</p>
<ol>
<li>
<b>Choose Report > Create Report</b>
<p>
The Create a New Report dialog box opens.
</p>
</li>

<li>
<b>Specify the directory in which you want the report files to be written</b>
<p>
If you wish to use a file chooser to specify the directory, click on
the Browse button.
</p>
</li>

<li>
<b>Click the Create Report(s) button</b>
<p>
The reports are generated and you are asked whether you want to view
the report.
</p>
</li>

<li>
<b>Click Yes</b>
<p>
The reports are displayed in the JT harness report browser
window. Scroll through the report and follow the various links to view
data about the test run.
</p>
</li>
</ol>
<p>
<b>Note: </b>If you wish to print the report, you can open the report
in your favorite web browser and print it from there.
