How to solve null pointer exception of webdriver in selenium - java

This is the code i have written below in junit. However it shows me a null pointer exception for the webdriver.
i have also printed "driver". it prints "drivernull"
*package demo;
import static org.junit.jupiter.api.Assertions.*;
import java.util.concurrent .TimeUnit;
import org.junit.Before;
import org.junit.jupiter.api.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
class Demo1 {
public WebDriver driver;
String url="www.google.com";
#Before
public void before() {
System.setProperty("webdriver.chrome.driver", "D:\\chromedriver.exe");
driver = new ChromeDriver();
driver.get(url);
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
#Test
public void test() throws Exception {
System.out.println("driver"+driver);
Thread.sleep(2000);
driver.findElement(By.xpath("//*[#id=\'prm\']/div/a")).click();
}
}*
This is the failure trace

Please check chromedriver.exe path. It should be in D: drive.
I am not seeing anything incorrect in your code.


It seems that something in your before() throws an exception because driver is null. So get(url) or manage().
Most likely it is get(url) (you can see that precisely in your stack trace)
So new ChromeDriver() probably fails, check your installation.
Hence, when test is called, driver member variable is still null, so the display is "null".
the get started example explicits the protocol in the path. This is most likely unrelated but you should change
String url="www.google.com";
to
String url="http://www.google.com";


Please change
String url="www.google.com";
to
String url="http://www.google.com";
Why do we need to do because driver.get method is not adding protocol like "http" or "https" before your url

Throwable t = assertThrows(RuntimeException.class, e);
}
#Test

assertTrue(room.isAvailable(null, stayLength));
room.checkout(booking);
verify(bookings).remove(booking);
assertTrue(room.isReady());
assertEquals(0,bookings.size());
}
}
I am getting error on this line while I am doing testing:
bookings.add(booking);
please tell me how can I fix this null pointer exception from the code so that it runs properly and my tests get successful.
Here is the complete error trace please guide me how to fix this issue:

Based on your code snippet, it looks like you have two methods i.e. book the hotel and check-out the same.
The general concept of unit test to test the code written in that particular class. So, your end goal will be to test book and checkout method in the different test case.
You are getting java.lang.NullPointerException because your bookings attribute is null due to wrong use of #Spy annotation.
#Spy
List <Booking> bookings = new ArrayList<>();
You should use #Spy as shown above and it will solve your null pointer exception:
You can refer below link to read how to use #Spy # https://www.baeldung.com/mockito-spy

i need to write testcase for connectTimeout and SocketTimeout exception. Am using powerMock to create mock objects. Below is my code. But am getting null pointer exception for my mock objects. Any help appreciated

Below is my Sender class send method
public String send(JSONObject vent) throws IOException{
String method;
int level;
HttpsURLConnection conn = null;
try {
URL obj = new URL(url);
conn = (HttpsURLConnection) obj.openConnection();// line number 81
conn.setRequestMethod(method);
initializeURL(conn);
....
}
catch(SocketException e){
}
catch(ConnectException e){
}

Acording to powermock documentation, in the section mock constructor, you should be doing something like that:
URL mockURL = PowerMockito.mock(URL.class);
expectNew(File.class, url).andReturn(mockURL);
replay(mockURL, File.class);
Also, be sure to use annotations #PrepareForTest(Sender.class) and #RunWith(PowerMockRunner.class)

Finally i was able to solve it. Incase some gets the same issue again. In my code issue was withArguments line. I was trying to pass
String url="https://www.google.co.in/";
as the Url parameter. But in the actual it was null.
URL mockURL = PowerMockito.mock(URL.class);
PowerMockito.whenNew(URL.class).withArguments(url).thenReturn(mockURL);
withArguments try to match if the parameters are same. On having same url paramter on my mock and actual object in code i was able to proceed with out null pointer exception

First test fails on IntelliJ IDEA + Appium

I'm a new one to automation. I've set up an environment for test automation, but I'm unable to run my first test, errors occurs on each run. Have no idea what it is, please help me
Here is my code:

#Before
public void setUp() throws Exception {
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("devicename", "Testdevice");
androidDriver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
}
#Test
public void logInCheck() throws Exception {
androidDriver.findElement(By.id("com.example.mariia.testing:id/button")).click();
}
#After
public void tearDown() throws Exception {
androidDriver.quit();

You haven't set capabilities platformName, platformVersion,app and deviceName. You're testing Android app, so You need to provide additionally capabilites appActivity and appPackage.

DesiredCapabilities caps = new DesiredCapabilities();
caps.SetCapability("app-package", "com.myapp.test");
caps.SetCapability("browserName", "");
caps.SetCapability("device", "Android");
caps.SetCapability("app-activity", "com.myapp.SplashActivity");
caps.SetCapability("version", "4.1.2");
caps.SetCapability("device ID", "uniquedeviceid");
caps.SetCapability("app", "apk-path");
To narrow down your issue, please provide your testng.xml file.

the problem is located on the command driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);.
Can anyone please tell me why this is happening?

NoSuchfield exception is thrown if an application tries to access or modify a specified field of an object, and that object no longer has that field. If this error is happening at the Android driver instantiation, then it could be that some of capabilites you have may not be right. There is no such capability as appium-version - Link. Also device_name is ignored for Android. Try out below capabilities
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME,
"Selendroid");
capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, "Android");
capabilities.setCapability(MobileCapabilityType.PLATFORM_VERSION, "4.3");
capabilities.setCapability(MobileCapabilityType.APP_PACKAGE: "wizzo.mbc.net");
capabilities.setCapability(MobileCapabilityType.APP_ACTIVITY: "wizzo.mbc.net.activities.SplashActivity");

TestNG and Powermockito - cannot mock static void

I can't get Powermock work with TestNG. The same code adjusted to JUnit works fine, but somehow in TestNG it fails.
TestNG version is 6.8.21
Powermockito version is 1.6.1
package p;
import org.mockito.MockitoAnnotations;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import org.testng.Assert;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
import static org.powermock.api.mockito.PowerMockito.mockStatic;
#PrepareForTest({FooTest.class})
public class FooTest {
#BeforeTest
public void setup() {
mockStatic(FooTest.class);
MockitoAnnotations.initMocks(this);
}
#Test
public void test() throws Exception {
PowerMockito.doNothing().when(FooTest.class,"foo");
FooTest.foo();
Assert.assertEquals(1, 1);
}
public static void foo() throws Exception {
throw new Exception("huh?");
}
}
The exception I get is on the when method:

So what am I missing here?

I suspect this may be the same issue and solution as this question. In other words make sure you are using the org.powermock.modules.testng.PowerMockObjectFactory. But as #fge says, you should #PrepareForTest the class containing the static method(s) to mock, which should not be the test class itself...
