问题


In the Base class I initiate browser as static WebDriver driver = new FirefoxDriver();

Then do I need to include same static WebDriver driver = new FirefoxDriver(); in the second class ?

1 Case: Where I included static WebDriver driver = new FirefoxDriver(); in the second class as well however, during the execution second class in not executed. I used @BeforeMethod and @AfterMethod TestNG annotation as well in my both class. However, it is not working out for me. Please help me if I am doing anything wrong here.

In the below case I want to continue my test execution with second class from where I stopped my first Class test:

For example in the first class I logged into application and after login I am on Home page now. So now I want to further execute my second class from Home page onward. However, after executing first class and login into application, second class is not executing.

After Test suite execution in the "Result of running suite" tab show following error message for class 2:

Here is my testNG XML file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

Here is my Base class:

    @DataProvider(name="testdata")
    public Object[][] TestDataFeed(){

    try {

    wb=Workbook.getWorkbook(new File("C://File//Book2.xls"));

    // load sheet in my case I am referring to first sheet only

}

回答1:


As per provided example, you initiated webdriver in each class and quitting the same in that class. If you what to use same webdriver in two classes, then its good to initiate webdriver in one separate class and then extends this class to your test cases classes(nothing but yours base and second class).

let see one simple example, i will create a class config where i initiate my webdriver

 public class config{

static WebDriver driver;

@BeforeSuite
public void setup(){

    driver=new FirefoxDriver();

}

@AfterSuite
public void tearDown(){
    driver.quit();
}

}

Now, i will extend this class to my test cases/classes

   public class NewTest1 extends config{

   @Test
   public void test1() {
   driver.get("http://www.google.com");
   }
  }

for another class

  public class NewTest2 extends config{

@Test
public void MyTesting() {
         driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
  }
}

Now, execute these two classes from tesng.xml please note to use preserve-order="true" to execute test cases/classes as specified order

<?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
 <suite name="Suite" parallel="false" preserve-order="true">

  <test name="TestA">
    <classes>
      <class name="com.test.NewTest1"/>
      <class name="com.test.NewTest2"/>
    </classes>
  </test> <!-- Test -->
 </suite> <!-- Suite -->

Thank You, Murali
