Selenium Webdriver中的测试用例西装执行错误

Question

I have a test suite for 28 test cases(methods) in a single class. Whenever i'm trying to run these methods/ execute test case unexpected no of test cases are getting failed some times error comes in Sleep command some times something else. Error is not constant for any run.

     @Test (priority = 5)
  public void AddModule() throws Exception {

     Workbook wb = Workbook.getWorkbook(srcCNRegression);
     driver.get(baseUrl1);
     Thread.sleep(5000);
     ModuleLink = driver.findElement(By.linkText("MODULES & INTERVENTIONS"));
     Thread.sleep(5000);
     //HighlightElement.elementHighlight(ModuleLink);
     ModuleLink.click();
     System.out.println(" Module link is open");
     Thread.sleep(5000);
     driver.findElement(By.linkText("Add Modules")).click();
     Thread.sleep(3000);
     // Click on the modules
     driver.findElement(By.name("page:frm:j_id204:1:j_id206")).click();
     Thread.sleep(3000);
     driver.findElement(By.name("page:frm:j_id214")).click(); 
     Thread.sleep(3000);
     System.out.println("Module is added" );

  }

Answer 1

With having a errors occurred , corresponding code (alone with the web site url you testing if possible) it is hard give a specific answer . But I can give some suggestions

01) Remove Thread.Sleep() , implement wait for specific element

02) Comment out all the test and add one-by-one to isolate specific place you are getting the error . One reason for similar situation is Application not the state that particular test is expecting , so even if you see multiple tests getting fail , the actual reason for failing could be in single test
