Unable to locate element radio botton in Selenium webdriver

Question

I am a newbie trying to learn automation using the tool Selenium . I am trying to automate this website - http://newtours.demoaut.com/

where I login and try to access this radio button (one way, round way )for flight finder. But i am getting the error Unable to locate the element .

Tried the following.

1. Tried to locate the element using Xpath obtained from firebug .

2. Used the following Xpath composed from the html code to locate the radio button

    //*[@type='radio']//*[@value='oneway'] //*[contains(@type,'radio')] //*[contains(text(),'oneway'] //input[@type='radio' AND @value='oneway'] 

3. Also tried CSS selector to locate the element.

    driver.findElement(By.cssSelector("input[type=radio][value=oneway]")) 

4. Tried adding wait times using implicit wait and thread.sleep

The HTML script for the radio button as obtained from firebug is -

input type="radio" checked="" value="roundtrip" name="tripType"

          Round Trip       

input type="radio" value="oneway" name="tripType"

              One Way

Given below is my code -

package gurutrial2;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.Assert;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class gurutrial2 
{

    public static WebDriver driver;

    @BeforeTest

    public final void preTest() {

        System.setProperty("webdriver.firefox.marionette", "C:/Users/serajendran/Downloads/geckodriver-0.10.0 (1)");
        DesiredCapabilities capabilities = DesiredCapabilities.firefox();
        capabilities.setCapability("marionette", true);

        driver = new FirefoxDriver(capabilities);

        driver.get("http://newtours.demoaut.com/");
        driver.manage().window().maximize();
        System.out.println(driver.getTitle());

        Assert.assertEquals("Welcome: Mercury Tours", driver.getTitle());
    }

    @Test
    public final void login() {

        driver.findElement(By.name("userName")).sendKeys("invalidUN");
        driver.findElement(By.name("password")).sendKeys("invalidPW");
        driver.findElement(By.name("login")).click();
        System.out.println("login in progress");
    }

    @Test
    public final void flightFinder() {

        WebDriverWait wait = new WebDriverWait(driver, 30);
        WebElement oneWayRadioButton = wait.until(ExpectedConditions.elementToBeClickable(By.linkText("oneway")));
        oneWayRadioButton.click();
        System.out.println("Clicked One Way");
    }

}

Any help would be deeply appreciated.

Answer 1

//*[@type='radio']//*[@value='oneway'] - you're looking for an element of type radio and value oneway.. this xpath look for an element of type radio that has a child element with value oneway.

//*[contains(@type,'radio')] - you'll get multiple results for this

//*[contains(text(),'oneway'] - the text is not oneway, only the value attribute is oneway, the text contains 'One Way'

//input[@type='radio' AND @value='oneway'] - this should work if you change 'AND' to 'and'

以下解决方案在newtour网站上为我工作-

driver.findElement(By.cssSelector("input[value='oneway']")).click();

Answer 3

Actually the problem is in your test Methods

In TestNG the execution of @Test methods is in alphabetic order by default. So in your code flightFinder() method executing before login() So even you are using right locator to click on radio button, It will show the exception.

Solution:

1. Maintains your method name in alphabetic order

2. Use priority under @Test annotation for the methods eg - @Test(priority = 1)

3. Create dependency test eg -

    @Test() public final void login() { //code } @Test(dependsOnMethods={"login"}) public final void flightFinder() { //code } 

Update your code as below and try -

@Test
public final void doLogin() {

    driver.findElement(By.name("userName")).sendKeys("invalidUN");
    driver.findElement(By.name("password")).sendKeys("invalidPW");
    driver.findElement(By.name("login")).click();
    System.out.println("login in progress");
}

@Test()
public final void flightFinder() {

    driver.findElement(By.xpath("//input[@type='radio' and @value='oneway']")).click();
    System.out.println("Clicked One Way");
}
