Description:

In this course, you will learn how to write Unit tests and Integration tests in BDD style for Spring Boot applications as well as Spring WebFlux applications using JUnit 5, Mockito, AssertJ, Hamcrest, JsonPath, and Testcontainers frameworks.

Important note: This course updated to use Spring Boot 3.

Type the code along with me in the videos. If you follow along with me then this will enhance your learning experience.

The source code and PDF files (class notes) are available for download.

Spring Boot Overview

Spring Boot is an opinionated framework that helps developers build Spring-based applications quickly and easily.

The main goal of Spring Boot is to quickly create Spring-based applications without requiring developers to write the same boilerplate configuration again and again.

Spring Boot is a very popular framework to develop REST web services and microservices.

Spring WebFlux Overview

Spring 5 includes Spring WebFlux, which provides reactive programming support for web applications.

Spring WebFlux internally uses Project Reactor and its publisher implementations, Flux and Mono.

The new framework supports two programming models:

  • Annotation-based reactive components

  • Functional routing and handling

In this course, we will focus on building reactive REST APIs using annotation-based reactive components.

What you'll learn?

  • Learn to write industry-standard Unit and Integration tests in BDD (Behaviour Driven Development) style using Spring Boot Starter Test dependency from scratch

  • Learn how to use BDD (Behaviour Driven Development) format that is given/when/then to write Unit tests.

  • Learn to Unit test the Spring boot application Repository layer

  • Learn to Unit test the Spring boot application Service layer

  • Learn to Unit test the Spring boot application Controller layer

  • Learn how to do Integration testing for the Spring boot application.

  • Learn how to do Integration testing using Testcontainers // very important

  • You will learn to use the most important Unit Testing ANNOTATIONS - @SpringBootTest@WebMvcTest@DataJpaTest, and @MockBean

  • Use ALL the FRAMEWORKS in Spring Boot Starter Test - JUnit, Spring Test, Spring Boot Test, AssertJ, Hamcrest, Mockito, JSONassert, and JsonPath.

  • You will learn to write Unit tests using Mocks and Stubs created with Mockito

  • Learn how to use Mockito annotations to create mock objects.

  • Learn to Write Integration Tests using a MySQL database.

  • You will learn to Write INDEPENDENT Integration tests for RESTFUL web services by talking with MULTIPLE LAYERS - controller, service, and repository layers.

  • Learn Building Reactive CRUD REST APIs using Spring WebFlux

  • Learn Unit Testing Reactive CRUD REST APIs

  • Learn Integration Testing Reactive CRUD REST APIs

Looking for more deep dives courses such as Maven, Gradle, DevOps tools used in production"

"Awesome course.

All the basics needed to test a spring application are discussed, and more.

Exactly what i needed and coudn't find anywhere.

Ramesh is a great instructor.

Thank you sir !"

"A very good course explained with excellent examples.

the content of this course and explanation is great."

"Wonderful Sir, Loved the way u explain things. And I am very lucky that I found this course at right time."

"I am personally very impressed with this course, if you dont have any prior experience of unit testing I am pretty sure that after taking this course you will feel more confident and I would be happy if the lecturer could also release some training tutorials about Microservices and TDD approach. thanks and wish you all the successes."

"Even though as a experience guy, this course was very useful.."

"The course is great and covers all I need to create my tests.

I truly recommend it ."

"Great course. This is the second course I am taking from Ramesh. Interesting so far."
