Not recognizing text box while further code for radio button is written

[Sengar]

Hi,

i wrote code for selecting partial link text, link text, text box and then radio button.

Earlier code was working fine till text box selection and typing in it.

but now when i include code for radio button, it's throwing exception at text box selection line "NoSuchElementException".

//This code is for launching and closing the browser

package findelement;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.chrome.ChromeDriver;

import org.testng.annotations.AfterMethod;

import org.testng.annotations.BeforeMethod;

public class Browser{

WebElement element;

WebDriver driver; 

@BeforeMethod

public void launchBrowser(){

System.setProperty("webdriver.chrome.driver", "C:\\chromedriver.exe");

driver= new ChromeDriver();

}

@AfterMethod

public void closeBrowser(){

}

}

//Main class

package findelement;

import org.openqa.selenium.By;

import org.testng.annotations.Test;

@Test

public class Practice extends Browser{

public void practice(){

driver.get("http://www.toolsqa.com/automation-practice-form/?firstname=&lastname=&sex=Male&exp=1&continents=Asia&submit=");

driver.findElement(By.partialLinkText("Partial Link Test")).click();

driver.findElement(By.linkText("Link Test")).click();

driver.navigate().back();

driver.findElement(By.name("firstname")).sendKeys("Priyanka");

driver.findElement(By.name("lastname")).sendKeys("Sengar");

element = driver.findElement(By.id("sex-1"));

element.click();

}

}

Exception:

FAILED: practice

org.openqa.selenium.NoSuchElementException: no such element

Thanks for anticipating help.

element = driver.findElement(By.id("sex-1"));

Is this the line where the exception is thrown?

Looking at the site that indeed should not happen.

I only have one idea: Inspect the element with Firefox or Chrome or whatever and copy&paste the value under ID into your code. I had one case where the '-' sign was a very special one and thus different.

Thanks..it worked with XPATH.

But reason behind not recognizing text box is somthing else as XPATH worked only for next line. 

After that getting same issue.
