title: how to set delay between each tests in a testng.xml file
body: <p>i'm new to testng.i want to run a test on a parallel execution mode.i'm using 
  <code>selenium grid,
  selenium webdriver,
  testng</code>.</p>
  
  <p>my testng.xml file is:</p>
  
  <pre><code>`&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;suite name="WebDriver Suite" verbose="1" parallel="tests" thread-count="5"&gt;
  &lt;test name="WebDriver Test" &gt;
      &lt;parameter name="browser" value="firefox" /&gt;
      &lt;parameter name="port" value="5555" /&gt;
  &lt;classes&gt;
     &lt;class name="BootUpTest" &gt;
          &lt;methods&gt;
              &lt;include name = "testBootUp"/&gt;
          &lt;/methods&gt;
      &lt;/class&gt;
  &lt;/classes&gt;
  &lt;/test&gt;    
  &lt;test name="WebDriver Test for IE" &gt;
      &lt;parameter name="browser" value="chrome" /&gt;
      &lt;parameter name="port" value="5556" /&gt;
  &lt;classes&gt;
     &lt;class name="BootUpTest" &gt;
          &lt;methods&gt;
              &lt;include name = "testBootUp"/&gt;
          &lt;/methods&gt;
      &lt;/class&gt;
  &lt;/classes&gt;
  &lt;/test&gt;  
  &lt;/suite&gt;`
  </code></pre>
  
  <p>in the above xml file i supposed to run the <code>testBootUp</code> method in a<code>firefox</code> as well as <code>chrome</code>.i was able to run the above scenario.but my scope is i want to run the "<strong>WebDriver Test</strong>  test as first and then i need some delay after that only my <strong>WebDriver Test for IE</strong> test should have to run..</p>
  
  <p>is it possible to achieve that in the testng.xml file?. </p>
