There's been support for Testcontainers in Spring Boot for some time now, and Spring Boot 3.1 improves it further. But first, let's take a look at what Testcontainers is and how it's usually used.

Optionally you can also define environment variables, exposed ports, labels, how services relate to one another, and so on. Here's…

If you've used Spring Boot for a while, you're probably familiar with setting up connection details using properties. For example, you may have used spring.datasource.url to configure a JDBC connection.

It serves as a tagging interface, and is extended…
