  <para>
   If <parameter>mock</parameter> is a string containing the name of a class then it will be instantiated instead of
   <parameter>class</parameter>. <parameter>mock</parameter> can also be an object.
  </para>
  <note>
   <para>
    Only dynamic access to properties and methods will use the <parameter>mock</parameter> object.
    Static access still uses the original <parameter>class</parameter>.

      The mock to use in the form of a string containing the name of the class to use or an object.
      If a string is passed, it has to be the fully qualified class name. It is
      recommended to use the <code>::class</code> magic constant in this case.
