TestNG with IE webdriver - java

Hi Im a newbie to selenium, i was trying to use TestNG with IE webdriver, Now i cant instantiate the IE driver directly under the class (Not the main method). When i do that i get the below error:
Multiple markers at this line
- Syntax error on tokens, FormalParameter expected instead
- Syntax error on token(s), misplaced construct(s)
- Syntax error on token ""webdriver.ie.driver"", invalid
If i then put on a method with #BeforeSuite annotation, i need to pass the driver to every other test method in the class. Is there a way where i can by pass this passing the driver object.
Find below the sample code i am using:
package FirstTestNGPackage;
import java.io.File;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
public class FirstTestNGclass {
#BeforeSuite
public void SetDriverPaths()
{
File IEDriver = new File("C:\\Users\\REDACTED\\Desktop\\SeleniumJars\\IE Driver\\IEDriverServerX64_2.44.0.exe");
System.setProperty("webdriver.ie.driver", IEDriver.getAbsolutePath());
WebDriver Driver = new InternetExplorerDriver();
}
#Test
public void tester()
{
Driver.findElement(By.id("keywordInput")).sendKeys("REDACTED");
Driver.findElement(By.id("keywordInput")).sendKeys(Keys.ENTER);
Assert.assertEquals(Driver.findElement(By.xpath(".//*[#id='search_results']/h1/span/strong")).getText(), "REDACTED");
}
#BeforeTest
public void RMSLogin()
{
Driver.navigate().to("REDACTED");
}
#AfterTest
public void closeBrowser()
{
Driver.quit();
}
}

init you webdriver like this then you can use it in every method with this.driver.
public class FirstTestNGclass {
public WebDriver driver;
#BeforeSuite
public void SetDriverPaths()
{
// ....
this.driver = new InternetExplorerDriver();
}
// ....
}

One of the simple solution to this problem is to use a common driver class for your Test suite...so that we can use the same driver instance in all classes
Common driver class
public class Driver {
public static WebDriver driver=null;
public static WebDriver startdriver(String browser){
if(browser.equalsIgnoreCase("Chrome")){
System.setProperty("webdriver.chrome.driver", "path");
driver=new ChromeDriver();
}else if(browser.equals("IE")){
System.setProperty("webdriver.ie.driver", IEDriver.getAbsolutePath());
driver=new InternetExplorerDriver();
}
return driver;
}
}
you can create a driver instance like this
Driver.startdriver("IE");
You can use the driver object like classname.instance
Driver.driver.findElement(By.xpath("path"));
Hope this helps you...if you have any queries Kindly get back

Null pointer exception - driver null

I am starting learning Selenium in Java and I have a big obstacle.
import org.junit.After;
import org.junit.Before;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.openqa.selenium.Dimension;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class FirstTest {
WebDriver driver;
#Before
public void driverSetup() {
System.setProperty("webdriver.chrome.driver", "src/main/resources/chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.manage().window().setSize(new Dimension(1280, 720));
}
#After
public void driverQuit() {
driver.quit();
}
#Test
public void getMethod() {
driver.get("http://google.pl");
}
}
I don't know how to solve it because in "getMethod" the driver is NULL.
You have defined WebDriver driver; at the global level and then you are again defining and instantiating another WebDriver driver in the driverSetup method because of which the global driver never got instantiated.
You need to make a single line change in the driverSetup method and it would work.
Your driverSetup should be like:
#Before
public void driverSetup() {
System.setProperty("webdriver.chrome.driver", "src/main/resources/chromedriver.exe");
// Instantiating the global driver here
driver = new ChromeDriver();
driver.manage().window().setSize(new Dimension(1280, 720));
}
You were close. You have already defined an instance of WebDriver i.e. driver as a global instance as in:
WebDriver driver;
You can reuse the same instance in #Before, #Test and #After. So there is no need to declare any additional instace of WebDriver in #Before as you did:
WebDriver driver = new ChromeDriver();
Solution
The solution will be to use the same global WebDriver instance as follows:
WebDriver driver;
#Before
public void driverSetup() {
System.setProperty("webdriver.chrome.driver", "src/main/resources/chromedriver.exe");
driver = new ChromeDriver();
driver.manage().window().setSize(new Dimension(1280, 720));
}

clear method not working with testng but working without it

.clear() in my test script is not working with testng version 6.14.2 but when i am running the same code without testng the clear method is working as expected.
i am running the code as mentioned below:
driver.findElement(By.id("email")).clear();
But this loc is not performing any action.
Blockquote
clear() is working for me. refer the following snippet
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;
public class Testngexample {
private WebDriver driver;
#BeforeClass
public void setUp() {
System.setProperty("webdriver.chrome.driver","Add chromedriver path chromedriver.exe");
driver = new ChromeDriver();
}
#AfterClass
public void tearDown() {
driver.quit();
}
#Test
public void GoogleEarch() throws InterruptedException {
driver.get("https://www.google.com/");
driver.manage().window().maximize();
driver.findElement(By.name("q")).click();
driver.findElement(By.name("q")).sendKeys("testing");
Thread.sleep(5000);
driver.findElement(By.name("q")).clear();
Thread.sleep(5000);
driver.close();
}
}

"Cannot instantiate class" error while executing tests through Selenium Java TestNG

I'm using Selenium and TestNG for the first time and I've been trying to search an element by its ID but I keep getting an "Cannot instantiate class" error. This is my code:
import org.testng.annotations.*;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.*;
public class NewTesting {
WebDriver driver = new FirefoxDriver();
#BeforeTest
public void setUp() {
driver.get("http://book.theautomatedtester.co.uk/chapter1");
}
#AfterTest
public void tearDown() {
driver.quit();
}
#Test
public void testExample() {
WebElement element = driver.findElement(By.id("verifybutton"));
}
}
Maybe I missed installing something? I installed the TestNG plug-in for eclipse and added the WebDriver JAR files, do I need to do more?
I tried following multiple tutorials but I keep getting errors, I hope someone can help. Thanks in advance!
EDIT:
I now have this:
public class NewTest {
private WebDriver driver;
#BeforeTest
public void setUp() {
System.setProperty("webdriver.gecko.driver","C:\\Program Files\\Selenium\\FirefoxDriver\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("http://book.theautomatedtester.co.uk/chapter1");
}
#AfterTest
public void tearDown() {
driver.quit();
}
#Test
public void testExample() {
WebElement element = driver.findElement(By.id("verifybutton"));
}
}
It does open the website now but I'm getting a nullpointer exception now:
FAILED CONFIGURATION: #AfterTest tearDown
java.lang.NullPointerException
at NewTest.tearDown(NewTest.java:21)
Replace this set of imports:
import org.testng.annotations.*;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.*;
With:
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
import org.testng.annotations.AfterTest;
Additionally, you have to download the required format of GeckoDriver executable from mozilla/geckodriver, extract the binary and then initialize the FirefoxDriver.
Your effective code block will be:
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
import org.testng.annotations.AfterTest;
public class NewTesting {
WebDriver driver;
#BeforeTest
public void setUp() {
System.setProperty("webdriver.gecko.driver","C:\\path\\to\\geckodriver.exe");
driver = new FirefoxDriver();
driver.get("http://book.theautomatedtester.co.uk/chapter1");
}
#AfterTest
public void tearDown() {
driver.quit();
}
#Test
public void testExample() {
WebElement element = driver.findElement(By.id("verifybutton"));
}
}
If you're on windows, this previous question may be some help to you.
It mentions that you can download geckodriver, and then initialize your FirefoxDriver like this:
System.setProperty("webdriver.gecko.driver","G:\\Selenium\\Firefox driver\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();

When i want to run this program instead of run as application it will shown like "run as configuration". Why it will ask like this

I am very new to the selenium section please check this code in that when I want to run this application at its not run. Instead of running it will it will ask like run as configuration.
package com.shiftwizard.application;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class Login {
public WebDriver driver;
public void positive()
{
System.setProperty("webdriver.chrome.driver", "D:\\prasanth softwares\\chromedriver_win32\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("https://devtest-new.myshiftwizard.com");
driver.findElement(By.name("txtUserName")).sendKeys("cs#shiftwizard.com");
driver.findElement(By.name("txtPassword")).sendKeys("P#ssword!1");
driver.findElement(By.name("btnLogin1")).click();
}
public void negitive()
{
System.setProperty("webdriver.chrome.driver", "D:\\prasanth softwares\\chromedriver_win32\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.findElement(By.name("txtUserName")).sendKeys("cs#shiftwizard.com");
driver.findElement(By.name("txtPassword")).sendKeys("P#ssword1");
driver.findElement(By.name("btnLogin1")).click();
System.out.println(driver.findElement(By.id("reqPass")));
}
public void close()
{
driver.close();
}
}
This is my code while i want to run this application i get like run as configuration listed of the run as java application.
Try this:
// set you package name here
package Prabha;
import org.junit.After;
import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;

import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class Login {
public static WebDriver driver;
WebDriverWait wait5s = new WebDriverWait(driver,5);
#BeforeClass
public static void setUpClass() {
// set your exe location here
System.setProperty("webdriver.chrome.driver", "C:\\Users\\pburgr\\Desktop\\chromedriver\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
// set your profile folder here or remove this line
options.addArguments("user-data-dir=C:\\Users\\pburgr\\AppData\\Local\\Google\\Chrome\\User Data");
driver = new ChromeDriver(options);
driver.manage().window().maximize();
}
#Before
public void setUp() {}
#After
public void tearDown() {}
#AfterClass
public static void tearDownClass() {driver.close();driver.quit();}
#Test
public void login() throws InterruptedException {
// calling method "positive", the method "negative" still unused in this class
positive();
}
public void positive() throws InterruptedException {
driver.get("https://devtest-new.myshiftwizard.com");
// wait 5 seconds to load the page
wait5s.until(ExpectedConditions.elementToBeClickable(By.name("txtUserName"))).sendKeys("cs#shiftwizard.com");
driver.findElement(By.name("txtPassword")).sendKeys("P#ssword!1");
driver.findElement(By.name("btnLogin1")).click();
Thread.sleep(5000);
// to be continued...
}
public void negative() throws InterruptedException {
driver.get("https://devtest-new.myshiftwizard.com");
// wait 5 seconds to load the page
wait5s.until(ExpectedConditions.elementToBeClickable(By.name("txtUserName"))).sendKeys("cs#shiftwizard.com");
driver.findElement(By.name("txtPassword")).sendKeys("intentionally_wrong_password");
driver.findElement(By.name("btnLogin1")).click();
Thread.sleep(5000);
// to be continued...
}
}
The username seems to be invalid, but I believe you'll manage.

i got an error - java.lang.NullPointerException while running the selenium web driver code block

" Here is the code of selenium web driver in which i use POM design to define all the locators of the web page. So after running the code i got an error regarding the null pointer exception.
"
{
package Pages;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
public class LoginPage {
WebDriver driver;
By username = By.id("user_login");
By password = By.id("user_pass");
By login = By.id("wp-submit");
By rememberme = By.id("rememberme");
public LoginPage(WebDriver driver){
this.driver = driver;
}

driver.findElement(username).sendKeys("admin");
}
public void typepassword(){
driver.findElement(password).sendKeys("demo123");

}
public void clicklogin(){
driver.findElement(login).click();
}
}
"Here in this code i created an object of a login page and call all the locators using TestNG annotations."
{
package Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
import Pages.LoginPage;
public class verifylogin {
#BeforeTest
public void beforetest(){
System.setProperty("webdriver.chrome.driver","C:\\Users\\saniket.soni\\Desktop\\chrome\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get("http://demosite.center/wordpress/wp-login.php");
}
#Test
public void verifyvalidlogin(){
WebDriver driver = null;
LoginPage login_test = new LoginPage(driver);
login_test.typeusername();
login_test.typepassword();
login_test.clickrememberme();
login_test.clicklogin();
}
}
You might want to consider studying scope in java to understand what is happening in this issue. Here is an explanation for what is happening in your case.
In your public void beforetest() method, you're creating a driver, and using it, but when that method is done the driver variable goes out of scope, and you no longer have access to it.
Later, in your verifyValidLogin method, you're creating a new driver variable, and setting it to null:
WebDriver driver = null;
Then you pass this null driver to your LoginPage here:
LoginPage login_test = new LoginPage(driver);//driver is null here
So when you use it here:
public LoginPage(WebDriver driver){
this.driver = driver;
}
public void typeusername(){
driver.findElement(username).sendKeys("admin");
}
It's null
Try making these changes:
First, save your driver somewhere when you initialize it like this:
public class verifylogin {
//STORE YOUR DRIVER SOMEWHERE!!! Like here
private WebDriver driver;
#BeforeTest
public void beforetest(){
System.setProperty("webdriver.chrome.driver","C:\\Users\\saniket.soni\\Desktop\\chrome\\chromedriver.exe");
//Store the driver in the class variable
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get("http://demosite.center/wordpress/wp-login.php");
}
#Test
public void verifyvalidlogin(){
//Now you can use the driver you stored
LoginPage login_test = new LoginPage(driver);
login_test.typeusername();
login_test.typepassword();
login_test.clickrememberme();
login_test.clicklogin();
}
You are removing object reference by using "WebDriver driver = null" in verifyvalidlogin() method. Remove this line and try, it will work.
You instance variable 'driver' as private ('private WebDriver driver').
With 'private' access modifier you can access driver within the class but not from outside, change it to public it will work.
In beforetest() method you are instantiating the browser object and navigating to demo Url.
After that in verifyvalidlogin() method you are making driver object to null and passing this null object to Login page, here you are passing null instead of driver object.
We can solve this issue by declaring driver instance variable inside the class and outside of all methods like below.
WebDriver driver;
Instantiate this driver object in beforetest() method and pass the same driver object to LoginPage without declaring it again as mentioned below.(I executed this script in my local machine its working fine)
package Tests;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
import Pages.LoginPage;
public class verifylogin {
WebDriver driver;
#BeforeTest
public void beforetest(){
System.setProperty("webdriver.chrome.driver","C:\\Users\\saniket.soni\\Desktop\\ chrome\\chromedriver.exe");
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get("http://demosite.center/wordpress/wp-login.php");
}
#Test
public void verifyvalidlogin(){
LoginPage login_test = new LoginPage(driver);
login_test.typeusername();
login_test.typepassword();
login_test.clickrememberme();
login_test.clicklogin();
}
}
package Pages;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
public class LoginPage {
WebDriver driver;
By username = By.id("user_login");
By password = By.id("user_pass");
By login = By.id("wp-submit");
By rememberme = By.id("rememberme");
public LoginPage(WebDriver driver){
this.driver = driver;
}
public void typeusername(){
driver.findElement(username).sendKeys("admin");
}
public void typepassword(){
driver.findElement(password).sendKeys("demo123");
}
public void clickrememberme(){
driver.findElement(rememberme).click();
}
public void clicklogin(){
driver.findElement(login).click();
}
}
Try this solution and let me know if it works for you.
