!!!Testing of/with Plugins

The {{PluginManager}} has to be initialized with the plugins, so that the plugins can be tested or that can be used for testing (e.g. JUnit tests using the loading of a knowledge base).

Since it is not necessary for this task to build the entire application and the plugins, we propose a different procedure: 
You need to include the following code block into the {{pom}} file of the project having the JUnit test; the code is inserted into the plugin section of the build section.


With the help of the ''Maven Dependency Plugin'' a file is written into the target directory, that contains the classpath and thus all required plugins. 
For this, all plugins need to be specified as dependency, as it is done for building the application; however, the scope "test" is sufficient. 
The scope "compile" should be only applied to the main application and plugins, that are extending other plugins.

It is sufficient to execute {{InitPluginManager.init()}} in order to initialize the {{PluginManger}} with the JUnit test using the created file. 
Possibly, a test-dependency on {{d3web-PluginManger}} is required, if not already defined before. 
In Eclipse, we then execute the tests using the command 
{{{ Run As -> Maven Test}}}
which is also the command of Hudson when starting the tests on the integration server. Alternatively, the JUnit tests can be also started by 
{{{Runs As -> JUnit Test}}}
if a fresh file with the classpath is provided.
