Selenium :Basics of IReporter and IListener

IReporter and IListener

http://www.tutorialspoint.com/testng/testng_test_results.htm

• Listeners: Classes are notified at runtime by TestNG when the test starts, finishes, fails, skips, or passes.
• Reporters:  These classes are called when the whole suite run ends.
  
  

  Listeners And Reporters

  //1 . sample test script

   public class Sample{
      @Test
      public void testMethodOne(){
          Assert.assertTrue(true);
      }
     
      @Test
      public void testMethodTwo(){
   Assert.assertTrue(false);

    @Test(dependsOnMethods={"testMethodTwo"})
          public void testMethodThree(){
          Assert.assertTrue(true);
      } 
      }
  }

  
  //2. Listener Class
   
  

  import org.testng.ITestResult;
  import org.testng.TestListenerAdapter;
  
  public class CustomListener extends TestListenerAdapter{
      private int m_count = 0;
    
      @Override
      public void onTestFailure(ITestResult tr) {
          log(tr.getName()+ "--Test method failed\n");
      }
    
      @Override
      public void onTestSkipped(ITestResult tr) {
          log(tr.getName()+ "--Test method skipped\n");
      }
    
      @Override
      public void onTestSuccess(ITestResult tr) {
          log(tr.getName()+ "--Test method success\n");
      }
    
      private void log(String string) {
          System.out.print(string);
          if (++m_count % 40 == 0) {
       System.out.println("");
          }
      }
  }

  //3.IReporter

  public class CustomReporter implements IReporter{
      @Override
      public void generateReport(List xmlSuites, List suites,
          String outputDirectory) {
          //Iterating over each suite included in the test
          for (ISuite suite : suites) {
              //Following code gets the suite name
              String suiteName = suite.getName();
       //Getting the results for the said suite
       Map suiteResults = suite.getResults();
       for (ISuiteResult sr : suiteResults.values()) {
           ITestContext tc = sr.getTestContext();
           System.out.println("Passed tests for suite '" + suiteName +
                "' is:" + tc.getPassedTests().getAllResults().size());
           System.out.println("Failed tests for suite '" + suiteName +
                "' is:" + 
                tc.getFailedTests().getAllResults().size());
           System.out.println("Skipped tests for suite '" + suiteName +
                "' is:" + 
                tc.getSkippedTests().getAllResults().size());
         }
          }
      }
  } 

  
  //4. testng.xml
  
  

  <suite name="some Listener">
    <listeners>
      <listener class-name="CustomListener" />

      <listener class-name="CustomReporter" /> 
    </listeners>
  
    <test name="some name">
      <classes>
        <class name="Sample" />
      </classes>
    </test>
  </suite>

  
  //--------------Output--------------------------
  

  testMethodOne--Test method success
  testMethodTwo--Test method failed
  testMethodThree--Test method skipped
