      Class Test is used to configure test instances, which can 
      be configured by the following parameters:
      <@li>cmd: the command to be executed</@li>
      <@li>expected: the expected result</@li>
      <@li>count: number of executions of cmd</@li>
      <@li>pre: a command to be executed at the begin of the test (before cmd)</@li>
      <@li>post: a command to be executed after the test (after all cmds)</@li>
      <@li>namespace in which pre, post and cmd are evaluated; default ::</@li>
      The defined tests can be executed by <@tt>Test run</@tt>
