1. Welcome to Hands On – Junit

 

File Name – SolutionTest.java (under src->test folder)

 

package com.tcs.fresco;

 

import static junit. framework.Assert.*;

 

import java.util.HashMap;

import java.util.Map;

 

import org.junit.After;

import org.junit.Before;

 

import junit.framework.Test;

import junit.framework.TestCase;

import junit.framework.TestSuite;

 

public class SolutionTest extends TestCase{

    Map<Integer, String> customerTag = null;

               int custId = 0;

               Solution solution = new Solution();

   

    @Before

               public void setUp() throws Exception {

                              custId = 10511;

                              customerTag = new HashMap<Integer, String>();

               }

   

    //Write your test cases here

   

    public void test() {

               assertTrue( true );

    }

 

    @org.junit.Test

    public void testValidUser(){

      solution.saveCustomer(this.custId, "Tej");

      assertTrue(solution.isCustomerExist("Tej"));

    }

     @org.junit.Test

    public void testinValidUser(){

      solution.saveCustomer(this.custId, "Tej");

      assertFalse(solution.isCustomerExist("Tej1"));

    }

   

    @After

               public void tearDown() throws Exception {

                         customerTag.clear();

               }

}


2.Hands-on Mockito

 

File Name- UserAuthenticatorTest.java 

 

package com.tcs.fresco;

 

/* Write static mocks for Assert and Mockito classes. -Q1 */

 

import static org.junit.Assert.*;

import static org.mockito.Mockito.doThrow;

//Write import statements for Mockito classes.

import static org.mockito.Mockito.mock;

import static org.mockito.Mockito.when;

import org.junit.Before;

import org.junit.BeforeClass;

import org.junit.Test;

 

public class UserAuthenticatorTest {

 

               UserAuthenticator authenticator = new UserAuthenticator();

               public static UserAuthenticatorInterface authenticatorMock;

 

 

               @BeforeClass

               public static void setUp() {

      /* Create mock object using static mock configuration  -Q2 */

      //Write your code here

       authenticatorMock = mock(UserAuthenticatorInterface.class);

       

               }

 

               @Before

               public void setUpAuthenticator() {

                              authenticator.setUserAuthenticator(authenticatorMock);

               }

 

                 /*Complete the test case with the expected exception -Q3 */

 

      // Write your code here

  @Test(expected = FailedToAuthenticateException.class)

               public void testAuthenticate_InvalidCredentials() throws FailedToAuthenticateException {

 

                              String username = "User1";

                              String password = "wrong password";

                              String errorMessage = "Invalid credentials .Authentication Failed";

                             

        /*Throw exception using doThrow...when configuration - Q4*/

        // Write your code here

    doThrow(new FailedToAuthenticateException(errorMessage)).when(authenticatorMock).authenticateUser("User1", "wrong password");

                              authenticator.authenticateUser(username, password);

 

               }

 

               @Test

               public void testAuthenticate_ValidCredentials() throws FailedToAuthenticateException {

 

                              String username = "User1";

                              String password = "Password";

                   /*Configure Returning True with when...thenReturn configuration on mock Object - Q5*/

        //Write your code here

    when(authenticatorMock.authenticateUser(username, password)).thenReturn(true);

                              assertTrue(authenticator.authenticateUser(username, password));

 

               }

 

               @Test(expected=FailedToAuthenticateException.class)

               public void testAuthenticate_EmptyCredentials() throws FailedToAuthenticateException {

 

                              String username = "";

                              String password = "";

        String errorMessage= "Credentials cannot be empty";

        /*Configure Throwing exception using when...thenThrow configuration on mock Object - Q6*/  

        //Write your code here

       when(authenticatorMock.authenticateUser(username, password)).thenThrow(new FailedToAuthenticateException(errorMessage));

                    authenticator.authenticateUser(username, password);

        authenticator.authenticateUser(username, password);

 

               }

  1. Tried Junit handson many times but unable to clear it everytime. Even copy-pasting is not working. What to do now? Please help.
    1. Pls, do mention what problem are you facing exactly. Becoz we have tried and it is working!! Pls double check the code provided. Thanks!
  2. Copy pasted the exact entire code with file name "SolutionTest.java" and it's showing one test case has passed. Still, I'm not able to clear this handson.
    Also, in PROBLEMS section, it displays the message-- "SolutionTest.java is not on the classpath of project solution, only syntax errors are reported Java(32) [1,1]".

    What to do now? Please help.
