How to Use Test Slices To Test Spring Boot Faster 2021

Developers usually agree that unit testing is a critical aspect of software development. When unit tests are stable, rapid, and repeatable, they add the most value.
Without advanced optimization, tests can take a long time to run. Much of that time is lost on unnecessary app initialization, slowing down the feedback loop. In this tutorial, we'll share How to Uses Test Slices To Test Spring Boot Faster 2021

7 Test Frameworks To Follow in 2021 for Java/Fullstack Developers

It is time to learn new test frameworks in 2021 to improve your code quality and decrease the time of your testing phase. Let’s explore 6 options for devs.

It is time to learn new test frameworks to improve your code quality and decrease the time of your testing phase. I have selected six testing frameworks that sound promising. Some have existed for quite a long time but I have not heard about them before.

At the end of the article, please tell me what you think about them and what your favorite ones are.

Robot Framework

Robot Framework is a generic open-source automation framework. It can be used for test automation and robotic process automation (RPA).

Robot Framework is open and extensible and can be integrated with virtually any other tool to create powerful and flexible automation solutions. Being open-source also means that Robot Framework is free to use without licensing costs.

The RoboFramework is a framework** to write test cases and automation processes.** It means that it may replace** your classic combo Selenium + Cucumber + Gherkins**. To be more precise, the Cucumber Gherkins custom implementation you wrote will be handled by RoboFramework and Selenium invoked below.

For the Java developers, this framework can be executed with Maven or Gradle (but less mature for the latter solution).

Spring vs Spring BooDifference Between Spring and Spring Boot

As an extension of the Spring Framework, Spring Boot is widely used to make development on Spring faster, more efficient and convenient. In this article, we will look at some of the parameters were using Spring Boot can drastically reduce the time and effort required in application development.

Integration Testing in Spring Boot Application

Integration tests play a key role in ensuring the quality of the application. With a framework like Spring Boot, it is even easier to integrate such tests. Nevertheless, it is important to test applications with integration tests without deploying them to the application server.

Integration tests can help to test the data access layer of your application. Integration tests also help to test multiple units. For the Spring Boot application, we need to run an application in ApplicationContext to be able to run tests. Integration tests can also help in testing exception handling.

Spring Boot Application

For this demo, we will build a simple Spring Boot application with REST APIs. We will be using the H2 In-Memory database for storing the data. Eventually, I will show how to write an integration test. This application reads a JSON file of vulnerabilities from the National Vulnerability Database and stores it in the H2 database. REST APIs allow a user to fetch that data in a more readable format.

Consumer-Driven Contract Testing With Spring Cloud Contract

Introduction

The article demonstrates how to write a contract between the producer & the consumer and how to implements the producer & the consumer side test cases for Spring Cloud Contract through an HTTP request between two microservices.

Producer/Provider

The producer is a service that exposes an API (e.g. rest endpoint) or sends a message (e.g. Kafka Producer which publishes the message to Kafka Topic)

Consumer

The consumer is a service that consumes the API that is exposed by the producer or listens to a message from the producer (e.g. Kafka Consumer which consumes the message from Kafka Topic)

Contract

The contract is an agreement between the producer and consumer how the API/message will look like.

  • What endpoints can we use?
  • What input do the endpoints take?
  • What does the output look like?

Consumer-Driven Contract

Consumer-driven contract (CDD) is an approach where the consumer drives the changes in the API of the producer.

Consumer-driven contract testing is an approach to formalize above mentioned expectations into a contract between each consumer-provider pair. Once the contract is established between Provider and Consumer, this ensures that the contract will not break suddenly.

Spring Cloud Contract

Spring Cloud Contract is a project of spring-cloud that helps end-users in successfully implementing the Consumer Driven Contracts (CDC) approach. The Spring Cloud Contract Verifier is used as a tool that enables the development of Consumer Driven Contracts. Spring Cloud Contract Verifier is used with Contract Definition Language (DSL) written in Groovy or YAML.

Demo Application

To understand the concept of the Spring Cloud Contract, I have implemented two simple microservices. The code for these applications can be found on Github account.

request and response

Request and response between the consumer and the producer

Create-employee-application MS

It is the first microservice responsible for creating an employee’s profile based on the given details. We are only passing the FirstName, LastName, and Identification Number (e.g. National ID) of the employee. This microservice is calling another microservice to first check, based on the Identity Number, whether the profile has already been created for the employee.

Get-employee-application MS

This is the second microservice service that is just checking if an employee profile already exists. If the employee profile is matching with the Identification Number provided in the database, it will return the profile else return an empty profile with the EMPLOYEE_NOT_FOUND status.

The create-employee-application microservice is having a dependency on get-employee-application microservice, so we have written a contract of get-employee-application. We are not using any database here to store or retrieve employee details so that written simple logic which will help us to fetch the existing employee profile.

Setup

We are going to understand how we have done the setup for these applications. We are going to discuss the setup in each microservice one by one.
