<h1>AspectJ tests</h1>

<h3>Testing and Tests</h3>
Testing on the AspectJ project is fairly straightforward.
For compiler issues/bugs, we write harness tests.
For API issues/bugs, we write JUnit tests. 
We also have other testware for system testing.
<p>
This module contains test data and scripts, while the testing-drivers
and testing modules contain the harness.    

Tests differ in the kind of harness they use and their target.
(Many tests are unused and date back to earlier times in the project.)

These are compiler test cases, the preferred form for
any compiler tests.  The XML files are test definitions,
and the subdirectories contain the test sources.  Many of the
test source files are no longer used.  The test definitions are
segregated for convenience as follows:
<ul>
   <li><a href="ajcTests.xml">ajcTests.xml</a>: main test suite.
       After a release, these tests should always run and pass.
       </li>
   <li><a href="ajcTests10.xml">ajcTests10.xml</a>: 
       Tests for the 1.0 compiler.  In some cases, error tests
       differ between the 1.0 and 1.1 compiler only in the
       errors expected to be generated.
       </li>
   <li><a href="ajcTestsBroken.xml">ajcTestsBroken.xml</a>: 
	   These tests fail, and the tests are broken.  
	   The tests should be fixed and rolled into ajcTests.xml
       </li>
   <li><a href="ajcTestsFailing.xml">ajcTestsFailing.xml</a>: 
       These tests fail, and the compiler is broken.
       When fixed, these tests should be rolled into
       <a href="ajcTests.xml">ajcTests.xml</a>.
       </li>
   <li><a href="ajcTestsAttic.xml">ajcTestsAttic.xml</a>: 
       These are broken or failing tests not slated to be fixed.
       </li>
   <li><a href="ajcHarnessTests.xml">ajcHarnessTests.xml</a>: 
       These are tests to exercise the test harness itself.
       </li>
</ul>
To run the harness, use <code>org.aspectj.testing.drivers.Harness</code>,
in the <code>testing-drivers</code> module.  
For help on harness options, use <code>-help</code>.   
For for help on component options, see the package docs.
Note in particular how to select tests using keywords or supply compiler
arguments on the command line.
<p>
To write a new test, evolve an existing example.  See the dtd and/or
the javadoc for the testing harness implementation in the 
<code>testing</code> module for more details.

<p>To write a test case for a bug, see XXX todo.
   
<h3><a name="#product"></a>Product</h3>
Product tests target a built distribution or do compiler (argument) 
testing not supported by the harness.
Many have been superceded by ant tests.

<h3><a name="#ajctest"></a>AjcTest</h3>
   <a href="ajctest.xml">ajctest.xml</a>
   is an Ant script that compiles and runs large systems.
   The scripts tell the AjcTest task from the testing module to drive
   the sources in other-systems through compile/doc/run cycles.
   To set up the tests, the script combines the aspects checked in to 
   other-systems/ with the Java source files from various open-source
   projects, contained in aspectj-external-lib.zip.  
   <!-- XXX install and correct -->
   
   
<h3><a name="#jacks"></a>Jacks</h3>
Jacks is the Jikes compiler test suite available at the 
    <a href="http://www-124.ibm.com/developerworks/oss/cvs/jikes/~checkout~/jacks/jacks.html">
       Jacks project page</a>.

We have a bash script to run it using ajc and javac and compare
       the results.
