How to run test sequentially in TestNG?

Question

I am automatationg test using Selenium Webdriver in Java Language. I am using TestNG framework. I want to run test one after another in sequencial way. But i cannot do and getting error messages. My code is-:

@BeforeMethod

       public void setup() throws InterruptedException {

      System.setProperty("webdriver.gecko.driver", "C://Selenium driver/geckodriver.exe");

        DesiredCapabilities capabilities = DesiredCapabilities.firefox();

              capabilities.setCapability("marionette", true);

              driver=new FirefoxDriver();

              driver.get("http://newtours.demoaut.com");

              driver.manage().window().maximize();

              driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

       }

       @Test

       public void signIn() {

              driver.findElement(By.name("userName")).sendKeys("vickysingh");

              driver.findElement(By.name("password")).sendKeys("password");

              driver.findElement(By.name("login")).click();

       }

       @Test

       public void logOut(){

       driver.findElement(By.linkText("SIGN-OFF")).click();

       }

       @AfterMethod

       public void teardown() {

       driver.close();     

       } 

My first test is Passed but second test Fails. Second test should start after first test. How can I achive this.

Answer 1

After every execution you are closing the browser. So, in the first test, you opened the browser, you logged in and closed the browser by using @AfterMethond.

WebDriver opens every new session with cleared cache. So, when you tried to log out, you were already logged out. So, it throws element not found exception.

You can change @BeforeMethod and @AfterMethod to @BeforeClass and @AfterClass. This will not close the browser after every test method execution.

Or, you should copy your sign in code into your logOut() method to sign in first to do sign out test.

Hope that helps!
