FAILED CONFIGURATION: #BeforeMethod setUp : java.lang.NullPointerException

I have written the below code which is one of the program in designing a framework and it is giving me this below error everytime. Can some one pls help me in fixing this issue.
"[RemoteTestNG] detected TestNG version 7.0.1 FAILED CONFIGURATION: #BeforeMethod setUp java.lang.NullPointerException"

In the TestBase() class in line no 41. I have missed the driver initialization for chrome although it was added for firefox but not for chrome. I have added the below statement in the if statement and it worked for me.
driver = new ChromeDriver();

How to solve null pointer exception of webdriver in selenium

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

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:

import org.junit.After;
import org.junit.Before;
import org.openqa.selenium.By;
import org.openqa.selenium.remote.DesiredCapabilities;

public class FirstTest {
AndroidDriver androidDriver;
#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();
}
}
Here are the errors that i'm receiving:

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");

alwaysRun parameter in TestNG

Can someone please explain me when #AfterMethod(alwaysRun = true) should execute. Will it execute when #test method is skipped. In documentation is written so, but I have observed different behavior.
Example:
Code:
public class testing{
#Test
public void testCase2(){
System.out.println("in test case 2");
Assert.assertEquals(1,2);
}
#Test(dependsOnMethods = { "testCase2" })
public void testcase3(){
System.out.println("OK");
}
#AfterMethod(alwaysRun = true)
public void afterMethod2() {
System.out.println("in afterMethod");
}
}
Output:
in test case 2
in afterMethod
FAILED: testCase2

Shouldn't #After method be executed twice, also after skipped #Test?
Thanks for answer in advance :)

The documentation says
For after methods (afterSuite, afterClass, ...): If set to true, this
configuration method will be run even if one or more methods invoked
previously failed or was skipped.
So I think it should execute after skipped test method.

Even though the documentation has stated that
For after methods (afterSuite, afterClass, ...): If set to true, this
configuration method will be run even if one or more methods invoked
previously failed or was skipped.
However, in configfailurepolicy annotations, the following is stated when there's any test failures
configfailurepolicy: Whether TestNG should continue to execute the
remaining tests in the suite or skip them if an #before* method fails.
Default behavior is skip.
BTW, #AfterMethod is not a test method but a configuration one.

alwaysRun on #Test: A method (say method2) having this testng attribute willalways run even if the method on which it depends (dependsOnMethods="Method1") failed and it is referred as soft dependency in testNG terminology.
alwaysRun on #Before or #After annotated methods: if #BeforeSuite fails and #BeforeClass has alwaysRun = true then it won't be skipped. (although test case may get skipped)
public class TestAlwaysRun{
#BeforeSuite
public void toFailBeforeSuite() {
System.out.println("I'm beforeSuite, I will fail");
throw new RuntimeException();
}
#BeforeTest(alwaysRun = true)
public void toFailBeforeTest() {
System.out.println("BUG: I'm beforeTest, I will fail");
throw new RuntimeException();
}
#BeforeClass
public void toFailBeforeClass() {
System.out.println("BUG: I'm beforeClass, I will fail");
throw new RuntimeException();
}
#BeforeMethod(alwaysRun = true)
public void toFailBeforeMethod() {
System.out.println("BUG: I'm beforeMethod, I will fail");
//throw new RuntimeException();
}
#Test
public void tetsCase() {
System.out.println("I'm a Test Case");
}
}

I think here you have given dependsOnMethods = { "testCase2" }
That is why your second test itself isn't triggered and so aftermethod doesn't execute.
Please remove that depends and check ..it will execute aftermethod twice.

I have a test with an Error that gives no good information. The only piece of the stack that involves my code is the method call in the test which fails.

The class I'm trying to test works fine when I run it with grizzly and render it manually with a browser.
#Path("url")

#Context HttpHeaders hh
) {

if (hh.getRequestHeader("FULLNAME") != null) {
ctx.put("FULLNAME", hh.getRequestHeader("FULLNAME").get(0));
ctx.put("EMAIL", hh.getRequestHeader("EMAIL").get(0));
}
return ctx;
}

You may be able to get some more information out or a different traceback if you put some code like this somewhere in your package:
#Provider
public class CustomExceptionMapper implements
ExceptionMapper<Throwable> {
#Override
public Response toResponse(Throwable ex) {
System.out.println("EXCEPTIONMAPPER!!!!!!!!!!!!!!!!!!!!");
System.out.println(Exceptions.getStackTraceAsString(ex)); // <--
return Response.status(500).entity(
Exceptions.getStackTraceAsString(ex)
).type("text/plain").build();
}
}
