2 sections • 13 lectures • 1h 33m total length

Introduction1-Junit-Testing with spring boot and Mockito-Overview3:49
Learn to write JUnit test cases for each layer of a Spring Boot application using Mockito and Maven, ensuring reliability before deployment.
Introduction2-Master Java Unit Testing with Spring Boot and Mockito7:57
Learn how JUnit enables repeatable Java unit tests with Spring Boot and Mockito, define unit test and method under test, and verify outcomes with assertions.

Environment-setup-with-example12:46
Set up Eclipse IDE and a Spring Boot Maven project, generate from start.spring.io, add Spring Web and DevTools, and write a JUnit 5 test for a three-value addition.
Calculate Example4:31
Calculate the sum of an integer array using an enhanced for loop, then validate it with a JUnit test comparing actual and expected results, illustrating success with green outputs.
Junit-Session 5- Calculate-with-empty-single3:59
Lead Junit testing with spring boot and Mockito by designing tests for a sum function with empty, single, and null inputs, validating zero, one, and failure cases.
Junit-Session6-Example to call a calculate service4:00
Develop and test a calculate service by wiring a service interface, getters and setters, and retrieving data from a real-time source in a Spring Boot and JUnit environment.
Junit-Session 7-ServiceImplementation with Stub6:42
Learn to unit test a service implementation using a stub instead of a database, by creating a calculate service stub, wiring it into tests, and verifying expected results.
8-Calculate-Servce-Stub-with empty and single values5:37
Learn to create empty and single-value stubs for a calculate service in JUnit tests, verify zero and one results, and discuss why mocking the service is preferred.
9-Create-MockService-for-CalculateSum13:17
Learn to replace a stub with a mock service using Mockito to test calculate sum and simplify unit tests with a single mock instead of multiple stubs.
10-Refactoring @Mock @InjectMocks12:09
Refactor tests by using @Mock and @InjectMocks with Mockito extension, reducing repeated setup via @Before and @After, and clarifying mock versus inject mock behavior in JUnit 5.
11 Unit testing with List example6:28
Learn to write Java unit tests for lists using JUnit, creating a mock list, validating single and multiple values, and using parameter-based values for test cases.
12-Junit-Annotations6:13
Explore essential JUnit annotations across versions, from @Test and @BeforeAll to @BeforeEach and @AfterEach, with @TestFactory, @Nested, @Tag, and modern extension models for Spring Boot and Mockito.
13-Junit-Spy6:29
Explain the difference between mocks and spies in JUnit testing with Spring Boot and Mockito, illustrate partial mocks with a list example, and discuss when to use spies versus mocks.

Requirements

The prerequisites are Minimum java knowledge and Spring boot knowledge.

Description

JUnit is a unit testing framework for Java programming language. JUnit has been important in the development of test-driven development, and is one of a family of unit testing frameworks collectively known as xUnit, that originated with JUnit.

This tutorial explains the use of JUnit in your project unit testing, while working with Java. After completing this tutorial you will gain sufficient knowledge in using JUnit testing framework from where you can take yourself to next levels.

Most of the successful projects are running based on successful junit test cases. Do you want to write Junit test cases for your project then this is the right place to learn about junit testing with spring boot and mockito. In this course you will be familiar about Junit test cases and Mockito, you can also write controller based unit tests and service based unit test and many more live examples.

Students will learn to write JUNIT test cases very effectively.

Students will learn to Write INDEPENDENT JUnit Tests for RESTFUL web services talking with MULTIPLE LAYERS - web controller, business and data.

Students will learn and explore to use the most important Unit Testing ANNOTATIONS -

Test, SpringBootTest, WebMvcTest, DataJpaTest and MockBean, InjectMocks, Mock

Students will learn to write unit tests using MOCKS and SPYS created with MOCKITO.

Students will learn to write unit test with H2 database with JPA and will explore about integration.

Students will be explore to work with Eclipse IDE, Spring boot framework, Mockito framework and maven technologies.
