The first time you checkout the current project to a new workspace, 

you have to prepare it to be able to work easily with maven from

eclipse itself.

Perform the following steps:

1.- Launch the *prepare-workspace.xml* ant build file. 

    You can do it by loading the file into the ant view, 

    and running the default task, or right-clicking the 

    file from the package explorer or the navigator and

    select the option: *Run as > Ant build*. 

2.- Restart eclipse.

3.- Import the subprojects of the project you have just checked out.

Those steps are only needed once per workspace.

Put into this folder the resources needed by your test classes.

This folder is added to the Tests classpath, so you can load any resources 

through the ClassLoader.

By default, in this folder you can find an example of log4j configuration,

prepared to log messages through the console, so logging works when you

run your tests classes.
