1. JUnit Hands-On

  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. Mockito 

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);

}

    @Test()

    public void dummytest(){

        assertEquals(1,1);

    }

}
