It looks like you are not returning json from get operation.
Can you use accept method & see if your test able to evaluate jsonpath?
MvcResult mvcResult = this.mockMvc.perform(get("/api/v1/user/{userId}/notifications/count",100))
.accept(MediaType.APPLICATION_JSON).... //call other methods

Cant apply rest controllers junit tests correctly

I am trying to apply junit test for my rest controllers.
I've tried to apply junit 4 but I got 404 error instead 200.
It looks like something is not initialized but cant't figured what.
Here is tutorial I have tried to apply.
https://www.youtube.com/watch?v=8S8o46avgAw
I also tried some different tutorials with junit 5 but the result was the same.
Here you can find the whole project.
https://github.com/WojciechWeg/tiny-bank/tree/tests
Just before publishing this post I've applied the following:
#Before
public void setUp() throws Exception {
mockMvc = MockMvcBuilders.standaloneSetup(customerController)
.build();
customer = new Customer("Jan","Kowalski",new Date(),"Marszalkowska",new ArrayList<>());
customerService.createNewCustomer(customer);
System.out.println("Customers from service: "+ customerService.getAllCustomers());
}
But the result of it is:
Customers from service: []
So it returns nothing. Above snippet is not in repo link.

Have you tried below approach without injecting mocks?
MockMvcBuilders.standaloneSetup(new CustomerController())
.build();
EDIT:
I've ran your code locally.
Do this:
mockMvc = MockMvcBuilders.standaloneSetup(new CustomerController(customerService))
.build();
And add slash to the beginning of URL
mockMvc.perform(get("/api/customers/1"))
.andExpect(status().isOk());

ArrayIndexOutOfBoundsException when accessing the getter on an object created by Spring's class converter

I'm converting one object to another object, but when I try to use the getter on the object that was created, I'm getting an ArrayIndexOutOfBoundsException.
The data is a simple String in the field and is on a very straight-forward object.
I've gotten this same issue with both Spring Boot 2.1.1 & 2.1.7.
Note: To replicate the issue, I have to run using mvn test, mvn install, or use Eclipse' code coverage tool. Using Eclipse's Run or Debug utils succeeds without error.
Exception:

In order to get around this issue, I had to change from using spring's reflective ConversionService methods to just manually plugging in the values in the converter.
I won't be marking this as the solution as it doesn't really fix the issue if you need to use reflection, but I'm putting it here to serve as a work-around.

iCustomerProxy.insertCustomer(customerDTO);
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_INFO, "Added Successfully", ""));
}
}

Any help would be appreciated.

Yup, as #Kayaman pointed out in comments, adding spring core dependency should solves it.
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>5.0.2.RELEASE</version>
</dependency>

The problem was for my other dependencies version
I changed them and problem solved

Spring controller unit testing with spring-test-mvc is failing

I am learning unit testing of spring controller with EasyMock and Spring test framework. I have done a simple unit testing for my controller.
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
import com.firstmav.domain.Employee;
import com.firstmav.service.EmployeeService;
#Controller
public class DataController {
#Autowired
EmployeeService employeeservice;
#RequestMapping("form")
public ModelAndView getform(#ModelAttribute Employee employee){
return new ModelAndView("form");
}
#RequestMapping("reguser")
public ModelAndView registeruser(#ModelAttribute Employee employee){
employeeservice.insertRow(employee);
return new ModelAndView("redirect:list");
}
#RequestMapping("list")
public ModelAndView getlist(){
List<Employee> employeelist = employeeservice.getList();
return new ModelAndView("list", "employeeList", employeelist);
}
#RequestMapping("delete")
public ModelAndView deleteitem(#RequestParam int id){
employeeservice.deleteRow(id);
return new ModelAndView("redirect:list");
}
#RequestMapping("edit")
public ModelAndView edititem(#ModelAttribute Employee employee, #RequestParam int id){
Employee employeeObject = employeeservice.getRowByID(id);
return new ModelAndView("edit", "employeeObject", employeeObject);
}
#RequestMapping("update")
public ModelAndView updaterow(#ModelAttribute Employee employee){
employeeservice.updateRow(employee);
return new ModelAndView("redirect:list");
}
}
and i have my failing test case here.
import org.junit.Before;
import org.junit.Test;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
import com.firstmav.controller.DataController;
public class DataControllerTest {
private MockMvc mockmvc;
#Before
public void setup(){
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/pages/");
viewResolver.setSuffix(".jsp");
mockmvc = MockMvcBuilders.standaloneSetup(new DataController()).setViewResolvers(viewResolver).build();
}
#Test
public void main() throws Exception{
mockmvc.perform(get("/form")).andExpect(status().isOk()).andExpect(view().name("form"));
}
}
I have included the controller import in the test case but i always getting the noclassdeffound exception.

I don't understand where i am making the mistake. Can any one help me or point me to right direction?

The issue is not related with your code.You're missing the library(jar) which contains javax.servlet.ServletException.So at runtime you're getting this exception.Check you class path if you have the servlet-api.jar in that location.
Though adding servlet-api.jar into your class path location should resolve the issue but if you want you can also check the jars that have this class here
