/**
 * Observer that executes the Before / After phases on the test case if the current test is in RunMode Client. <br/>
 * <br/>
 * BeforeClass/AfterClass are ALWAYS executed on Client side and NEVER In Container. <br/>
 * In Container does not keep state between @Test, so Before/AfterClass works the same as Before/After.<br/>
 * <br/>
 * Before/After are ONLY executed on Client side if the @Test's RunMode is Client. <br/>
 * <br/>
 * <p>
 * BeforeX event execution has a low precedence to execute as late in the Before Phase as possible.<br/>
 * AfterX event execution has a high precedence to execute as early in the After Phase as possible.<br/>
 * (compared to other Arquillian @Observers)<br/>
