This file contains test cases for javacertstoreplugin.
Following classes are tested in these tests:
CJavaCertStoreImpl, CJavaCertStoreToken and CJavaCertStoreTokenType

Test environment:
This unit test set uses actual java captain to retrieve certificate information
from the javacertstore which extension plugin of the java captain.
Purpose of the Extensionplugin (part of the test code) is stop javacertstore extension plugin 
from the java captain. This is needed because javacertstore caches its data and otherwise we
would not have been able to change certificate data in the file system.


/**

 *    - enabled, can be removed, can be disabled
 *    - disabled, can be removed, can be disabled
 *    - deleted, can be removed, can be disabled
 * 2. - Read certificates using MCTWritableCertStore::List() operation.
 *    - Read content of returned certificates by MCTWritableCertStore::Retrieve()
 *      operation.
