Cannot invoke "org.openqa.selenium.JavascriptExecutor.executeScript(String, Object[])" because "jse" is null

Any idea why I get NullPointerException here. Error - java.lang.NullPointerException: Cannot invoke "org.openqa.selenium.JavascriptExecutor.executeScript(String, Object[])" because "jse" is null
I am trying to input date (disabled field). Tests are running on Android.
This is a page object model framework with cucumber ,appium and Java.

Cucumber Selenium - Java - PageFactory : Step Definition: java.lang.NullPointerException

Hi community: I'm facing the next issue: I'm working with Cucumber, Selenium WebDriver using Page Factory. The error getting here is from the Step Definition side:
java.lang.NullPointerException
at pages.page_First.startNavigation(page_First.java:33)
at stepdefs.stepdefs_First.iGoToGoogle(stepdefs_First.java:20)
at ✽.I go to Google (file:src/test/resources/features/first.feature:10)
This is the part of the code (StepDefinition) where issue occurs:
#Given("I go to Google")
public void iGoToGoogle() {
page_first.startNavigation();
}
From the Page side, this is the code:
public class page_First extends BasePage {
public page_First() {
PageFactory.initElements(driver, this);
}
///////////////////////WEB ELEMENTS///////////////////////
#FindBy(name = "q")
private WebElement searchText;
#FindBy(name="btnK")
private WebElement searchButton;
//////////////////////BASE METHODS//////////////////////
public void startNavigation() {
driver.get(PropertyManager.getInstance().getURL());
}
public void search(String search) {
setTextAs(searchText, search);
}
public void enterButton (){
clickElement(searchButton);
}
}
The feature file:
Scenario Outline: Search google.com to verify google search is working
Given I go to Google
When I query for "<search>" cucumber spring selenium
And click search
Then google page title should become the first page
Examples:
| search |
| Cucumber Selenium |
This is my Browser class:
public class Browser {
// Take the instance of WebDriver
public static WebDriver driver;
public WebDriver initializeBrowser() throws IOException {
//Properties taken from config.properties
String browser = PropertyManager.getInstance().getBrowser();
if(browser.equals("chrome")) {
WebDriverManager.chromedriver().setup();
driver = new ChromeDriver();
} else if(browser.equals("firefox")) {
WebDriverManager.firefoxdriver().setup();
driver = new FirefoxDriver();
} else if(browser.equals("ie")) {
WebDriverManager.iedriver().setup();
driver = new InternetExplorerDriver();
} else if(browser.equals("edge")) {
WebDriverManager.edgedriver().setup();
driver = new EdgeDriver();
} else if(browser.equals("opera")) {
WebDriverManager.operadriver().setup();
driver = new OperaDriver();
} else {
System.setProperty("webdriver.safari.driver","/usr/bin/safaridriver");
driver = new SafariDriver();
}
System.out.println("-----> Proceed to initialize driver <-----");
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
driver.manage().window().maximize();
return driver;
}
}
and here is my configuration property reader class:
public class PropertyManager {
private static PropertyManager instance;
private static final Object lock = new Object();
private static String propertyFilePath = System.getProperty("user.dir") + "//src//main//resources//data//config.properties";
///////////////////////////// DATA IN PROPERTIES //////////////////////////
private static String url;
private static String browser;
//Create a Singleton instance. We need only one instance of Property Manager.
public static PropertyManager getInstance () {
if (instance == null) {
synchronized (lock) {
instance = new PropertyManager();
instance.loadData();
}
}
return instance;
}
//Get all configuration data and assign to related fields.
private void loadData() {
//Declare a properties object
Properties prop = new Properties();
//Read config.properties file
try {
prop.load(new FileInputStream(propertyFilePath));
} catch (IOException e) {
System.out.println("Configuration properties file cannot be found");
}
//Get properties from config.properties
url = prop.getProperty("url");
browser = prop.getProperty("browser");
}
public String getURL () {
return url;
}
public String getBrowser () {
return browser;
}
}
I was forgetting this, my Step Definition class:
public class stepdefs_First {
private page_First page_first = PageFactory.initElements(Browser.driver, page_First.class);
#Given("I go to Google")
public void iGoToGoogle() {
page_first.startNavigation();
}
#When("I query for {string} cucumber spring selenium")
public void iQueryForCucumberSpringSelenium(String search) throws Exception {
page_first.search(search);
}
#And("click search")
public void clickSearch() {
page_first.enterButton();
}
#Then("google page title should become the first page")
public void googlePageTitleShouldBecomeTheFirstPage() {
System.out.println("All OK");
}
}
By the way, this is my config.properties
browser = firefox
url = https://www.google.cl
Please I need your help.

Initialize the Page Object class
page_First page_first=new page_First();

Storing initialized drivers in a Java List but appearing null on fetching them

In my selenium code in Java I have to use multiple drivers. So I am declaring them in the class and storing them in a list. Then in a method I am initializing them but when I fetching them using get(index function) I am getting their value as null but if I use them directly then value is appearing. See Below:
Here I am declaring my drivers:
public static WebDriver driver1 = null;
public static WebDriver driver2 = null;
public static WebDriver driver3 = null;
public static WebDriver driver4 = null;
public static WebDriver driver5 = null;
public static WebDriver driver6 = null;
Now I am storing them in a list just after that:
public List<WebDriver> Drivers = Arrays.asList(driver1, driver2, driver3, driver4, driver5, driver6);
Then in a method I am initializing the drivers which is called from my tests.
public void initializeDrivers(String driver) throws InterruptedException, AWTException, IOException {
if(driver.equals("driver1") && driver1==null) {
System.out.println("First browser is opening");
driver1 = getDriver();
} else if(driver.equals("driver2") && driver2==null) {
System.out.println("Second browser is opening");
driver2 = getDriver();
} else if(driver.equals("driver3") && driver3==null) {
System.out.println("Third browser is opening");
driver3 = getDriver();
System.out.println("Login with qa softphone 1");
SFLP.softphoneLogin(driver3, CONFIG.getProperty("qa_test_site_name"), CONFIG.getProperty("qa_user_3_username"), CONFIG.getProperty("qa_user_3_password"));
//setDefaultSetting(driver3);
} else if(driver.equals("driver4") && driver4==null) {
System.out.println("Fourth browser is opening");
driver4 = getDriver();
} else if(driver.equals("driver5") && driver5==null) {
System.out.println("Fifth browser is opening");
driver5 = getDriver();
} else if(driver.equals("driver6") && driver6==null) {
System.out.println("Sixth browser is opening");
driver6 = getDriver();
}
}
Code for getDriver:
public WebDriver getDriver() {
WebDriver driver = null;
ChromeOptions options = new ChromeOptions();
if(System.getProperty("os.name").contains("Windows")){
System.setProperty("webdriver.chrome.driver", System.getProperty("user.dir")+"\\src\\test\\resources\\ChromeDriver\\chromedriver.exe");
}
options.addArguments("--test-type");
options.addArguments("--start-maximized");
options.addArguments("--use-fake-device-for-media-stream");
options.addArguments("--use-fake-ui-for-media-stream");
//Initializing a driver
driver = new ChromeDriver(options);
return driver;
}
Now when I fetch drivers directly as driver1 then I am getting the driver in it but when I fetch it using the list Drivers.get(1) I get value as null. Any help is well appreciated. Thanks in advance.

Update your code as given below.
Change 1: Drivers should be static.
public static List<WebDriver> Drivers = Arrays.asList(driver1, driver2, driver3, driver4, driver5, driver6);
Change 2:
public void initializeDrivers(String driver) throws InterruptedException, AWTException, IOException {
if(driver.equals("driver1") && driver1==null) {
System.out.println("First browser is opening");
driver1 = getDriver();
Drivers.set(0, driver1);
} else if(driver.equals("driver2") && driver2==null) {
System.out.println("Second browser is opening");
driver2 = getDriver();
Drivers.set(1, driver2);
} else if(driver.equals("driver3") && driver3==null) {
System.out.println("Third browser is opening");
driver3 = getDriver();
Drivers.set(2, driver3);
System.out.println("Login with qa softphone 1");
SFLP.softphoneLogin(driver3, CONFIG.getProperty("qa_test_site_name"), CONFIG.getProperty("qa_user_3_username"), CONFIG.getProperty("qa_user_3_password"));
//setDefaultSetting(driver3);
} else if(driver.equals("driver4") && driver4==null) {
System.out.println("Fourth browser is opening");
driver4 = getDriver();
Drivers.set(3, driver4);
} else if(driver.equals("driver5") && driver5==null) {
System.out.println("Fifth browser is opening");
driver5 = getDriver();
Drivers.set(4, driver5);
} else if(driver.equals("driver6") && driver6==null) {
System.out.println("Sixth browser is opening");
driver6 = getDriver();
Drivers.set(5, driver6);
}
}

Selenium GRID Test execution

I am trying hard to run my Selenium Test not local but in a grid.
I thought I am doing good but I don´t get it to run.
HUB and NODE are Up and running(started with CMD) and I am using the right IP adresses.
Please let me know what I am doing wrong! Do you think it maybe could be a problem with a proxy?
Greetings Arno (student from Germany)

Check your url, usually the default port for the Selenium Hub is 4444, also try the following:

How can i send multiple test data using testng in to following

Please suggest me how to sent 3 users in 3 browsers for this field
driver.findElement(By.id(PropertiesConfiguration.getMyProperty("PinTextfield"))).sendKeys(PropertiesConfiguration.getMyProperty("user"));
// main class
public class TestHRWW {`main class`
protected WebDriver driver;
#Parameters("browser")`parameter for browser initialization`
#BeforeClass
public void setup(String browser) {
if (browser.equalsIgnoreCase("firefox")) {
driver = new FirefoxDriver();
} else if (browser.equalsIgnoreCase("iexplorer")) {
System.setProperty("webdriver.ie.driver","Drivers\\IEDriverServer.exe");
driver = new InternetExplorerDriver();
} else if (browser.equalsIgnoreCase("chrome")) {
System.setProperty("webdriver.chrome.driver","Drivers\\chromedriver.exe");
driver = new ChromeDriver();
}
else {
throw new IllegalArgumentException("The Browser Type is Undefined");
}
driver.manage().window().maximize();
}
#BeforeMethod
public void open() {
driver.get("http://www.myhrasiapacific.com/");
}
#AfterClass
public void teardown() {
try {
driver.quit();
} catch (Exception e) {
driver = null;
}
}
// sub class
public class Login extends TestHRWW {`sub class`
String x;
static Logger logger = Logger.getLogger(Login.class.getName());
#Test
public void ClickLogon(WebDriver driver) throws InterruptedException, IOException {
driver.findElement(`enter code here`
By.id(PropertiesConfiguration.getMyProperty("logonbutton")))
.click();
Thread.sleep(2000);
// here i need to sent 3 differt users credentials
driver.findElement(
By.id(PropertiesConfiguration.getMyProperty("PinTextfield")))
.sendKeys(PropertiesConfiguration.getMyProperty("user"));
Thread.sleep(2000);
driver.findElement(
By.id(PropertiesConfiguration
.getMyProperty("passwordTextfield"))).sendKeys(
PropertiesConfiguration.getMyProperty("password"));
Thread.sleep(2000);
driver.findElement(
By.id(PropertiesConfiguration.getMyProperty("loginbutton")))
.click();
driver.manage().timeouts().implicitlyWait(120, TimeUnit.SECONDS);
}
}

You shall use TestNG #DataProvider to pass username & passwords
your login method will be like
#Test(dataProvider="dataForLogin")
public void ClickLogon(String userName,String password) {
}
#DataProvider(name="dataForLogin")
public static Object[][] prepareDataForLogin(){
// preparation of login data
}

If you are using QAF then you don't need to manually parse your json data and get rid from data provider class.
public class tDataHelper {
private static List<String> studentsToCreate = new ArrayList<String>();
static void parseData() throws Exception {
studentsToCreate.add("user1");
studentsToCreate.add("user2");
studentsToCreate.add("user3");
}
#DataProvider
public static Object[][] createStudents() {
Object[][] objArray = new Object[studentsToCreate.size()][];
for (int i = 0; i < studentsToCreate.size(); i++) {
objArray[i] = new Object[1];
objArray[i][0] = studentsToCreate.get(i);
}
return objArray;
}
}
public class testStudents {
private static tDataHelper helper = new tDataHelper();
#BeforeClass
public void setup() throws Exception {
tDataHelper.parseData();
}
#Test(dataProvider = "createStudents", dataProviderClass = tDataHelper.class)
public void testCreateStudents(String studentsToCreate) {
System.out.println(studentsToCreate);
}
}
