Appium PageFactory.initElements throws java.lang.NoSuchMethodException: jdk.proxy2.$Proxy8.proxyClassLookup() , on JDK Higher than 8

I'm trying to run an Appium test with selenium, PageFactory.initElements
this Code works only on JDK Amazon corretto-1.8
getting an error on all higher JDKs. (11,15,19)
My actual Goal is to upgrade my Java project level to JDK 11 or higher.

How to get rid of NullPointerException in Mockito unit test

I want to unit test rentBook method that is rensposible for renting.
Here is the #Service

this.bookRentalsRepository = bookRentalsRepository;
this.userRepository = userRepository;
}
public String rentBook(int userID, int bookID) {

From the stack trace, it seems it fails because you didn't mock also the user repository.
Add the following:
#Mock
UserRepository userRepository;
...
when(userRepository.doesAccountExistsWithGivenID(user.getId()).thenReturn(true);

Junit for RestController - Assertion Error

I have created an rest api and tested via postman and able to get success response as expected. Now i have created Junit test case for the above api but while executing getting "java.lang.AssertionError: Status expected:<200> but was:<415> ". Not able to figure out why this exception is happening.
I'm new to both Mockito and MockMVC so any help would be appreciated.

The issue is on this line:
#MockBean
private MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter;
You are mocking this converter. Create a instance using new instead:
this.mockMvc = MockMvcBuilders
.standaloneSetup(controller).
setMessageConverters(new MappingJackson2HttpMessageConverter()).build();
Or as rightly mentioned by M. Dienum, you can do away with the below 2 lines from setUp() method and it'll work:
DemoController demoController = new DemoController(demoService);
this.mockMvc = MockMvcBuilders
.standaloneSetup(demoController).
setMessageConverters(mappingJackson2HttpMessageConverter).build();
After doing all this if you run into 400 error then your toString() method isn't producing valid json.

How to solve internal error from server (test)?

guys. I'm testing method and in test it's name is testGetAuthorizedUserPublicInfo. This method have to return an User object. (So i created getUser method which return our new user).
Then after calling some methods on mockMvc objects try to perform get method (url is the same like in Controller class).
But i getting 500 response (instead of 200).
Can anyone say where is my mistake?? it would be really great )

Error while implementing Junit 4 (Mockito)

here is my junit which i am trying to implement.
import static org.mockito.Mockito.when;
import java.util.HashMap;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.runners.MockitoJUnitRunner;
#RunWith(MockitoJUnitRunner.class)
public class Power_Test {
#InjectMocks
ReportUtil w_res = new ReportUtil();
CollectionUtil mock = org.mockito.Mockito.mock(CollectionUtil.class);
#Test
public void test_removeHashedSettings() throws Exception {
HashMap<String, String> w_abc = new HashMap<String, String>();
w_abc.put("abc", "89");
when(mock.createHashMap("abc:89",":")).thenReturn(w_abc);
Assert.assertEquals(ReportUtil.removeHashedSettings("1", "abc:89", ":"),"abc:89:",0);
}
}
I want to mock createHashMap() method which is static method.
Below is an error trace which i am getting while running the above junit.
org.mockito.exceptions.misusing.MissingMethodInvocationException:
when() requires an argument which has to be 'a method call on a mock'.
For example:
when(mock.getArticles()).thenReturn(articles);
Also, this error might show up because:
1. you stub either of: final/private/equals()/hashCode() methods.
Those methods cannot be stubbed/verified.
Mocking methods declared on non-public parent classes is not supported.
2. inside when() you don't call method on mock but on some other object.

please help.
here is createHashMap Api

if( w_StrTkn.countTokens() == 0 || (w_StrTkn.countTokens()%2) != 0 )
{
LOGGER.warn("CollectionUtil:createHashMap:Invalid number of tokens to hash: "+ a_NameValStr+":"+w_StrTkn.countTokens() );
return w_KeyVal;
}
while (w_StrTkn.hasMoreTokens()) w_KeyVal.put( w_StrTkn.nextToken(), w_StrTkn.nextToken());
return w_KeyVal;
}
