A Practical Example of Cucumber's Step Definitions in Java

This third section of the guide focuses on the Step Definition Java classes. We use the real example project, and map the Gherkin sentences to Java methods with the so-called Step Definition files. You���ll learn about Cucumber���s built-in Parameter Types and you���ll create your own one. Besides, we���ll put into practice the best practices to keeping the state in a separate abstraction layer.

Cucumber's skeleton project structure and API Client

The second part of this Guide introduces the real-life example project of Cucumber tests for end-to-end functional scripts. You���ll create the skeleton project, design the structure of packages and classes, and implement the HttpClient to trigger API calls to the backend system. Besides, we���ll add already two complete Cucumber���s Feature files using the most important Gherkin syntax���s functionalities.

Full Reactive Stack ��� Introduction

This guide focuses on the capabilities of Spring WebFlux and Spring Boot 2 to create a��Reactive Web Application,��supported by a code example that you can build step by step.

To avoid��dumb, non-realistic examples where Spring is also the client of the Reactive API, you will complete the stack with a client application in��Angular 9. To make it reactive,��you���ll use Server-Sent Events (SSE) to communicate the backend with the frontend. See the figure below for a quick view of the stack we���...

Full Reactive Stack with Spring Boot, WebFlux and MongoDB

Within this chapter, you���ll learn how to develop the Reactive Web Server. We���ll use Spring WebFlux, available since Spring 5, and included from the Spring Boot 2.0 version. We���ll connect to a Mongo database using its reactive driver with Spring Data, also via Spring Boot.

Full Reactive Stack: Conclusions

In this final section, we run the application and see how everything works for the two different approaches: WebFlux with Server-Sent Events and MVC blocking classic. This post compares those two alternatives as well, in terms of user���s experience, performance and ease of development.

How to test a controller in Spring Boot - a practical guide

There are different ways to test your Controller (Web or API Layer) classes in Spring Boot, some provide support to write pure Unit Tests and some others are more useful for Integration Tests. Within this post, I���ll cover the main three test approaches available for Spring: using MockMVC in standalone mode, MockMVC together with SpringRunner, and using SpringBootTest.

Updated: Code examples use Java 14 and Spring Boot 2.3 with JUnit 5.
