THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
...
In the past, tests were numbered sequentially (it001,it002, etc). This becomes problematic because it's not always obvious what the issue is related to the test. More importantly, it's hard to create and submit sequential tests via patches because non-committers have no way to reserve the next number. This leads to extra work to apply the patch.
New New tests should be named using the Jira Issue JIRA issue id along with a meaningful name. This name should typically be the subject of the issue or a subset. It should be informative of the issue but not excessively long. Therefore a good name would be: mng1234-groupIdOrderIsBackwards.This name is typically used in several places of the test: the folder MavenITmng1234groupIdOrderIsBackwardsTest. The corresponding resource directory for this test in core-integrationit-testssuite/src/test/resources/ that contains the sample project along with the name of the junit class used to invoke the sample project and check the results would simply be named mng-1234, i.e. without the description to keep the path short.
Sample IT Project
A sample project has been created to aid in IT test creation. It can be retrieved using svn hereor Subversion from our source repository or directly viewed with your browser herevia our SVN view.
Sample IT Archetype Archetype
This project has also been converted into an archetype to make it even easier to use. (NOTE: This is currently not deployed and bugs prevent this from being usable right now. Use the Sample IT project for now and skip this section -Brianf 8/8/07)

The Archetype Plugin doesn't currently know about this archetype, so we created a catalog file to be used.

The maven-archetypeng-plugin is currently a snapshot. You will need to add the snapshot repository to your settings to be able to retreive the plugin and the archetype (when it gets deployed).

The archetypeNG plugin maintains a list of known archetype groups for interactive prompting. The next step is to add the IT group:
ARCHETYPE-82: You must manually create archetype.xml in your $HOME/.m2 folder and it must minimally contain the following:

|---|
<?xml version="1.0" encoding="UTF-8"?><archetype-registry> |
| No Format |
|---|
mvn archetypeng:add-groups -Dgroups=org.apache.maven.its

The project will be created in a subfolder of your current directory with the name you chose for the artifact. (my-it in the above example)ARCHETYPE-83: prevents us from continuing with this story...

The directory src/test/java/ contains a junit file used to execute the sample project. It is heavily commented to guide you along. Stop here and Take a look before continuing.
The directory src/test/resources contains a sample project tree that will be invoked to test our condition. The sample consists of a few modules, first an extension (checkstyle-assembly) that is jarred up and installed into the repository. Then a second invocation is made on a project that uses the extension (checkstyle-test)
The sample IT project uses the simplest method of using the verifier, that is the sample build fails if the test should fail. More complicated ITs can be created with beanshell scripts to check complex conditions. (Example Needed) (Link to verifier docs)

Submitting your IT Test
Now that your IT is complete, create a zip, tgz or some other *normal* archive of your test and attach it to your Jira JIRA issue.
If you are a Maven committer, read the next section to see how to integrate your test into the core, or to apply someone else's test.
Integrating an IT into the core-integration-tests
First, check out the core-integrationit-testssuite
The sample project maps directly to the core-integrationit-tests suite structure. Assuming the test has been named uniquely, you can copy the contents of src/test directly over to core-integrationit-tests suite (don't copy from the root or you'll overwrite the pomPOM).

Don't panic if some tests fail. That's probably normal. Only Panic panic if your test doesn't fail and it was supposed to (especially if you didn't write it).
