1. Introduction

Sprint Boot is a popular Java framework that provides a rich platform for integration testing. It’s pretty convenient and flexible; however, at a large scale, when the project has hundreds or even thousands of integration tests using lots of heavy components (like TestContainers-managed beans), there can be performance and other issues. There are many hidden details that make much sense when the codebase becomes bigger and the configuration becomes more complicated. In this article, we’ll look at how the framework works under the hood, why it can be slow and inefficient, and how to boost the performance.
