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());

i searched stackoverflow for any solution to a similar error, but i didn't find any, any solution suggested to fix this ?

check the object at line 64 it return null
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.

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.

I am using pageObject Model for my selenium automation.
Consider following browser config class.
package BrowserConfig;
import org.junit.After;
import org.junit.Before;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class crossBrowserConfiguration {
By logInPanel = By.xpath("//div[#id='logInPanelHeading']");
public static WebDriver driver = null;
WebDriverWait wait = new WebDriverWait(driver,30);
#Before
public void initBrowser(){
driver = new FirefoxDriver();
driver.manage().window().maximize();
driver.get("Website that contains Login Page");
wait.until(ExpectedConditions.visibilityOfElementLocated(logInPanel));
}
#After
public void closeBrowser(){
driver.quit();
}
}
I have a page object of Log in screen.
package PageObjects;
import org.openqa.selenium.By;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import BrowserConfig.crossBrowserConfiguration;
public class LoginScreen extends crossBrowserConfiguration {
WebDriverWait wait = new WebDriverWait(driver,30);
By userName = By.xpath("//input[#id='txtUsername']");
By password = By.xpath("//input[#id='txtPassword']");
By loginButton = By.xpath("//input[#id='btnLogin']");
By welcomeNote = By.xpath("//a[#id='welcome']");
By empListVerify = By.xpath("//div[#id='employee-information']/a");
public void logIN(String UserName, String Password){
driver.findElement(userName).sendKeys(UserName);
driver.findElement(password).sendKeys(Password);
driver.findElement(loginButton).click();
wait.until(ExpectedConditions.visibilityOfElementLocated(welcomeNote));
//Employee List Verification
String empListBtnText = driver.findElement(empListVerify).getText();
System.out.println(empListBtnText);
}
}
And finally, I have the following test case script:
package TestCases;
import org.junit.Test;
import BrowserConfig.crossBrowserConfiguration;
import PageObjects.LoginScreen;
public class initiateBrows extends crossBrowserConfiguration{
LoginScreen Obj1 = new LoginScreen();
#Test
public void runThis() throws Exception{
Obj1.logIN("admin", "123456");
}
}
When I run my test as JUnit Test, it gives nullPointerException without running at all. Stack trace for the exception is:

refers to WebDriverWait wait = new WebDriverWait(driver,30);
Any insight into why am I facing this exception?
The wait field is initialized when the an object of the class is created. This happens before JUnit calls the #Before method. Therefore the driver object is null. There are different ways of fixing the issue. One is making the driver object a simple field and initialize it immediately.
public class crossBrowserConfiguration {
By logInPanel = By.xpath("//div[#id='logInPanelHeading']");
public final WebDriver driver = new FirefoxDriver();
WebDriverWait wait = new WebDriverWait(driver,30);
#Before
public void initBrowser(){
driver.manage().window().maximize();
driver.get("Website that contains Login Page");
wait.until(ExpectedConditions.visibilityOfElementLocated(logInPanel));
}
#After
public void closeBrowser(){
driver.quit();
}
}
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.result.MockMvcResultMatchers.*;
import com.firstmav.controller.DataController;
public class DataControllerTest {

#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
