Look inside

You’re a senior developer at Travel World Agency (TWA), which has grown to become the largest travel agency in the world. The company has built a next-generation system that uses a microservice architecture running on Amazon Web Services (AWS). But while the company’s success is moving quickly in the right direction, the performance of its reservations microservice has taken a wrong turn. As a solution, TWA has replaced this microservice with a new one, using Kotlin and Spring Boot to improve performance and maintainability. Your job is to reduce the risk of deploying the application with bugs—a common problem for the previous API—by implementing robust testing.

Following business-driven development (BDD) practices, you’ll create a series of unit tests that validate the code’s logic in a number of plausible scenarios. To test the behavior of the code itself without affecting or being influenced by external classes, you’ll create a series of mocks. Using several libraries, you’ll test to ensure database queries work as expected.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

book resources

When you start your liveProject, you get full access to the following books for 90 days.

project author

Andres Sacco

Andres Sacco is a technical leader at Prisma. He has experience with many programming languages including Java, PHP, and Node.js. At his previous job, Andres helped find alternative ways to optimize data transfers between microservices, which reduced the cost of infrastructure by fifty-five percent. A co-author of Beginning Scala 3, published by Apress, Andres has also dictated internal courses about new technologies and shared his expertise in articles on Medium.

prerequisites

This liveProject is for Java and Kotlin developers interested in learning how to reduce the risk of deploying microservices with bugs. To begin these liveProjects you’ll need to be familiar with the following:

TOOLS
  • Any IDE: IntelliJ IDEA, Eclipse
  • Basic Spring and Spring Boot
  • Intermediate Maven
  • Basic Docker and Docker Compose
TECHNIQUES
  • Basic knowledge of Java or Kotlin
  • Basic knowledge of Spring Boot and how to add new modules
  • Basic Docker and Docker Compose commands
  • REST principles
  • Basic knowledge of microservices

you will learn

In this liveProject, you’ll learn to create tests that reduce the risk of deploying microservices with bugs.

  • Create a series of unit tests that follow BDD practices and test different plausible scenarios
  • Create a series of mocks that don’t affect and aren’t influenced by external classes
  • Write a unit test to validate that queries to access the database work as expected
