NullPointerException at "new RemoteWebDriver(srvc.getUrl(), options)"

I have Three Classes as below:
And When I run the test as TestNG from 'Tests.java' I get java.lang.NullPointerException exception:
NOTE:
-It picks the browser name 'chrome' successfully from the .properties file.
-If I discard the 'Tests.java' class and move the #Test method to 'LaunchBrowserTemp.java' class and add remaining corresponding tags (i.e. BeforeClass, BeforeMethod, AfterClass, AfterMethod) to corresponding methods in 'LaunchBrowserTemp.java' it works fine. It fails only when I keep the testng annotations to the 'Tests.java' class.

Error -> cucumber.runtime.CucumberException: Failed to instantiate class <class> - this class doesn't have an empty or a page enabled constructor"

I am using the FirefoxDriverInstance as the singleton for calling driver. Also, using a firefox profile to bypass 2-factor-authentication.
public class FirefoxDriverInstance {
public static WebDriver Instance = null;
public static void Initialize() {
if (Instance == null) {
System.out.println("Initializing Firefox Driver!!!");
System.setProperty("webdriver.gecko.driver","./src/test/resources/driver/geckodriver2.exe");
ProfilesIni profile = new ProfilesIni();
FirefoxOptions options = new FirefoxOptions();
options.setProfile(profile.getProfile("SeleniumTester"));
Instance = new FirefoxDriver(options);
}
Instance.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
Instance.manage().window().maximize();
}
public static void close() {
System.out.println("Closing Browser!!!");
Instance.close();
Instance = null;
}
public static void quit() {
System.out.println("Quitting Browser!!!");
Instance.quit();
Instance = null;
}
}
Below is my login code using cucumber-selenium-webdriver. I have used the same driver instance.
public class TC01_Login {
#BeforeMethod
public void openbrowser() throws IOException {
FirefoxDriverInstance.Initialize();
}
public Properties propertyFileReader() throws Exception {
Properties obj = new Properties();
FileInputStream objfile = new FileInputStream(System.getProperty("user.dir")+"\\src\\test\\resources\\testdata\\application.properties");
obj.load(objfile);
return obj;
}
WebDriverWait wait = new WebDriverWait(FirefoxDriverInstance.Instance, 150);
#Given("^user has entered the required URL$")
public void user_has_entered_the_required_URL() throws Throwable {
Properties obj = propertyFileReader();
System.out.println("In the First Loop!!");
FirefoxDriverInstance.Instance.get(obj.getProperty("baseUrl"));
String actualTitle = FirefoxDriverInstance.Instance.getTitle();
System.out.println("Actual Title :" + actualTitle);
if (actualTitle.contains("test")){
System.out.println("INFO : Title is being displayed as expected.");
}
else {
System.out.println("ERROR : Title is NOT being displayed as expected."); }
}
}
Unable to understand how to bypass this error.

Try to put below code in constructor :
FirefoxDriverInstance.Initialize();
Example:
public class TC01_Login {
public TC01_Login (){
FirefoxDriverInstance.Initialize();
}
}
Remove it from BeforeMethod

Can't make Actions.class methods work unless driver instance declared in #Test

I'm new to Selenium & new to Java as well. So maybe I'm missing something obvious, but I’m spinning on this for a while now, can't move forward & totally desperate. Please help!
Here is my set-up:
My custom Driver class implements WebDriver & sets property:
public class Driver implements WebDriver {
private WebDriver driver;
private String browserName;
public Driver(String browserName) throws Exception {
this.browserName = browserName;
if(browserName.equalsIgnoreCase("chrome")) {
System.setProperty("webdriver.chrome.driver", "src/test/resources/chromedriver");
this.driver = new ChromeDriver();
}
else if(browserName.equalsIgnoreCase("firefox")) {
System.setProperty("webdriver.gecko.driver", "src/test/resources/geckodriver");
this.driver = new FirefoxDriver();
}
else {
throw new Exception("Browser is not correct");
}
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}
<...>
}
BaseTest class gets property & creates new instance of the Driver inside #BeforeClass method (browser name passed with a maven command when running the test):
String browserName = getParamater("browser");
driver = new Driver(browserName);
In the Test class inside the #Test I create new Actions & pass there the driver from BaseTest:
Actions builder = new Actions(driver);
Action mouseOverHome = builder
.moveToElement(pb.testGoodle)
.build();
mouseOverHome.perform();
And this code doesn’t work -> no Actions performed (no mouse over or anything), no errors too.
However if I create & define new WebDriver inside the #Test itself:
System.setProperty("webdriver.gecko.driver", "src/test/resources/geckodriver");
WebDriver driver = new FirefoxDriver();
Actions perfectly working.
Any ideas or hints very appreciated!

Resolved! Resolved! The problem was in messed Actions declaration in Page Object! Here how things look in the Page Object:
protected Driver driver;
public static Actions act;
public PlanBuilder(Driver driver) {
this.driver = driver;
PageFactory.initElements(driver, this);
this.act = new Actions(driver);
}
public void rightClick (WebElement element) throws InterruptedException {
// Actions builder = new Actions(basedriver);
Action openContextMenu = driver.act
.contextClick(element)
.build();
openContextMenu.perform();
Thread.sleep(4000);

Selenium Grid (RemoteWebDriver) usage with Cucumber jvm SharedDriver

I implemented cucumber-jvm picocontainer with SharedDriver and works well locally. I would like to use Selenium Grid which has been configured well but I don't know how should I modify Shareddriver class in order to use RemoteWebDriver instead of WebDriver and connect to Selenium GRID.
new RemoteWebDriver(new("http://..../wd/hub"), capability); doesn't work because I need to throw MalFormedException and REAL_DRIVER is a static field.
Any idea? Thanks!
public class SharedDriver extends EventFiringWebDriver {
private static final WebDriver REAL_DRIVER = WebDriverFactory.internetExplorerWebDriver();
private static final Thread CLOSE_THREAD = new Thread() {
#Override
public void run() {
REAL_DRIVER.close();
}
};
static {
Runtime.getRuntime().addShutdownHook(CLOSE_THREAD);
}
public SharedDriver() {
super(REAL_DRIVER);
}
#Override
public void close() {
if(Thread.currentThread() != CLOSE_THREAD) {
throw new UnsupportedOperationException(
"WebDriver should not close!"
);
}
super.close();
}
#Before
public void deleteAllCookies() {
manage().deleteAllCookies();
}
#After
public void embedScreenshot(Scenario scenario) {
...
}
}
WebDriverFactory:
class WebDriverFactory {
static {
System.setProperty("webdriver.ie.driver", "src/test/resources/webDrivers/IEDriverServer.exe");
}
static WebDriver internetExplorerWebDriver() {
DesiredCapabilities returnCapabilities = DesiredCapabilities.internetExplorer();
System.setProperty("webdriver.ie.driver", "src/test/resources/webDrivers/IEDriverServer.exe");
returnCapabilities.setCapability("requireWindowFocus", true);
returnCapabilities.setCapability(InternetExplorerDriver.ENABLE_PERSISTENT_HOVERING, false);
returnCapabilities.setCapability(InternetExplorerDriver.IE_ENSURE_CLEAN_SESSION, true);
returnCapabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
returnCapabilities.setCapability("ignoreZoomSetting", true);
return new InternetExplorerDriver(returnCapabilities);
}

You can wrap the return statement into a try..catch block and return null in case of exception is being thrown.
class WebDriverFactory {
static {
System.setProperty("webdriver.ie.driver", "src/test/resources/webDrivers/IEDriverServer.exe");
}
static WebDriver internetExplorerWebDriver() {
DesiredCapabilities returnCapabilities = DesiredCapabilities.internetExplorer();
System.setProperty("webdriver.ie.driver", "src/test/resources/webDrivers/IEDriverServer.exe");
returnCapabilities.setCapability("requireWindowFocus", true);
returnCapabilities.setCapability(InternetExplorerDriver.ENABLE_PERSISTENT_HOVERING, false);
returnCapabilities.setCapability(InternetExplorerDriver.IE_ENSURE_CLEAN_SESSION, true);
returnCapabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
returnCapabilities.setCapability("ignoreZoomSetting", true);
try {
return new RemoteWebDriver(new URL("http://www.google.com"), returnCapabilities);
} catch (MalformedURLException e) {
return null;
}
}
then, check that the REAL_DRIVER value is not null.

Appium:I hv 2 class, ClassA & ClassB.I am executing these 2 class using testng.xml file.I want to know dat for ClassB do I need to put #Beforeclass?

Class1:
public class LaunchApp {
AndroidDriver<WebElement> driver;
#BeforeTest
public void Test1() throws MalformedURLException {
DesiredCapabilities capability = new DesiredCapabilities();
capability.setCapability("deviceName", "Android");
capability.setCapability("platformName", "Android");
capability.setCapability("platformVersion", "5.1.1");
capability.setCapability("deviceName", "Samsung Galaxy On5");
capability.setCapability("app",
"D:\\whatsapp.apk");
capability.setCapability("PackageName",
"com.movocado.socialbostonsports");
capability.setCapability("ActivityName",
"com.movocado.socialbostonsports.Activity.LogInSceen");
try {
driver = new AndroidDriver<WebElement>(new URL(
"http://127.0.0.1:4723/wd/hub"), capability);
} catch (MalformedURLException e) {
e.printStackTrace();
}
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}
Class2:
public class DrawerMenuTest {
AndroidDriver<WebElement> driver;
#Test(priority = 1)
public void DrawerMenuIcon() {
WebElement drawerMenu = driver.findElement(By
.id("com.movocado.socialbostonsports:id/rel_drawer"));
try {
drawerMenu.click();
} catch (NullPointerException e) {
System.out.println(e.getMessage());
}
}
Problem:
Second class is showing NullPointerException. Suggest me a solution.

You are initializing AndroidDriver into LaunchApp but does not pass this driver reference into DrawerMenuTest where you are creating only refrence variable of AndroidDriver with null that's causes of NullPointerException.
To overcome it you should create separate singlton class which will give single instance of AndroidDriver to each and every class as below :-
public class DriverInit {
private AndroidDriver<WebElement> driver;
private static DriverInit driverInit = null;
public static DriverInit getInstance() {
if (driverInit == null) {
driverInit = new DriverInit();
}
return driverInit;
}
private DriverInit() {
DesiredCapabilities capability = new DesiredCapabilities();
capability.setCapability("deviceName", "Android");
capability.setCapability("platformName", "Android");
capability.setCapability("platformVersion", "5.1.1");
capability.setCapability("deviceName", "Samsung Galaxy On5");
capability.setCapability("app", "D:\\whatsapp.apk");
capability.setCapability("PackageName", "com.movocado.socialbostonsports");
capability.setCapability("ActivityName", "com.movocado.socialbostonsports.Activity.LogInSceen");
this.driver = new AndroidDriver<WebElement>(new URL(
"http://127.0.0.1:4723/wd/hub"), capability);
this.driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}
public WebDriver getDriver() {
return this.driver;
}
}
Now you can use this into LaunchApp class as below :-
public class LaunchApp {
AndroidDriver<WebElement> driver;
#BeforeTest
public void Test1() throws MalformedURLException {
driver = DriverInit.getInstance().getDriver();
//now do your stuff with this driver
}
}
And use in DrawerMenuTest class as below :-
public class DrawerMenuTest {
AndroidDriver<WebElement> driver;
#Test(priority = 1)
public void DrawerMenuIcon() {
//get driver instance first
driver = DriverInit.getInstance().getDriver();
WebElement drawerMenu = driver.findElement(By
.id("com.movocado.socialbostonsports:id/rel_drawer"));
try {
drawerMenu.click();
} catch (NullPointerException e) {
System.out.println(e.getMessage());
}
}
}
Hope it helps..:)
