Testing Spring Boot Applications Demystified Workshop

A full-day workshop to help developers become more confident and productive when implementing automated tests for Spring Boot applications.

Proudly presented by PragmaTech GmbH.

Workshop Overview

This workshop is designed to demystify testing in Spring Boot applications through hands-on exercises, covering everything from basic unit testing to advanced integration testing techniques. The workshop is divided into four lab sessions, each focusing on different aspects of testing Spring Boot applications.

• Lab 1: Introduction & Unit Testing
• Lab 2: Sliced Testing
• Lab 3: Integration Testing
• Lab 4: Pitfalls, Best Practices, and AI

Workshop Format

• Full-day workshop on-site or remote
• Four main labs, ranging from 70-110 minutes each
• Hands-on exercises with provided solutions
• Building on a consistent domain model (a library management system)
