This is introduction about Java unit testing with spring boot and Mockito and discussed about overview of the Junit.
Introduction2-Master Java Unit Testing with Spring Boot and Mockito
Learn to define a calculate service interface, call its retrieveCalculateSum method, and wire a real-time calculation flow with getter and setter patterns, paving the path to testing.
Learn to unit test a calculate service by creating a stub that doesn't touch the database, wiring the stub into tests, and verifying expected results with add example stub tests.
Create calculate service stubs for empty and single values to drive unit tests in Spring Boot with Java, illustrating when to use stubs versus mocking and achieving green outputs.
See how to create mock services to replace stubs for calculating the sum of three values, including empty and single inputs, to streamline unit tests and reduce maintenance.
Refactor test code by consolidating setup into mocks and injecting mocks with ExtendWith(MockitoExtension.class), using Before and After to reduce duplication and improve maintainability.
Practice unit testing a java.util.List using a mock, set when-then values for size, and verify results with assertEquals for single and multiple values.
Explore JUnit 4 and JUnit 5 annotations, including @Test and @BeforeAll and @BeforeEach. Learn about @AfterEach, @AfterAll, @Ignore/@Disabled, test factory, nested, tag, and extend with spring and mockito.
Explore how spy in Mockito wraps an existing instance and tracks interactions as a partial mock. Compare spies with mocks, noting that spies call real methods unless stubbed.
Explore Spring Boot fundamentals by building a hello world controller and writing JUnit tests for a spring-based web layer, including a REST controller, get mapping, and running on 8080.
Master junit testing for spring boot hello world controller by building web mvc tests with a request builder, get mapping, and spring extension to verify rest responses.
Verify a JUnit test case returns a 200 ok response from a Spring Boot controller, check status, content type, and hello world payload, using Postman for validation.
Build a spring boot example for student details by creating a sample student object in a controller that returns JSON, preparing for unit testing in the next session.
Explore JUnit testing for student details with practical test cases in Java, verify student data, run tests, and achieve green results with Spring Boot and Mockito.
Explore the service layer by defining a student business service, wiring it into the controller, and validating behavior with JUnit tests and mock services in Spring Boot.
Connect a Spring Boot app to an in-memory H2 database using JPA and Hibernate, configure dependencies and properties, and define a student entity with a primary key.
Insert student details into a JPA entity using an H2 in-memory database with Spring Boot. Configure dependencies and data source, then run the app to verify the entries in console.
Retrieve student details from a database using a JPA repository in a Spring Boot REST app, implementing a student repository and fetching all records.
Write a unit test to verify retrieving all student details by mocking the service response, avoiding DB access, and ensuring the get all students operation returns the expected list.
Learn to write unit tests for the service layer in Spring Boot, covering the business service and get all students functionality, including repository mocking and validating core service logic.
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.
