• One Container to Rule Them All - Until It Doesn’t

  3 projects | dev.to | 11 Mar 2025

  There are a handful of ways to start Testcontainers, including JUnit4 annotations, JUnit5 annotations, ApplicationContextInitializer, JDBC URL scheme, and manual container lifecycle control. Let's choose manual control for now as the least "magic" option:

  > I wonder if Rancher Desktop, et al, works with testcontainers.org?

  I don't use testcontainers myself, but it looks like as long as you are using Rancher Desktop >= 1.0.1 you should be just fine.[1]

• Spring Boot 3.1 RC1 is here - with support for Testcontainers and docker compose

  2 projects | /r/java | 23 Apr 2023

  Unfortunately, it still remains hard to use Testcontainers because of how wedded it is to junit4, five years after the release of junit 5. https://github.com/testcontainers/testcontainers-java/issues/970

• Spring, SchemaSpy DB docs, and GitHub Pages

  8 projects | dev.to | 12 Mar 2023

  Finally, we put the directory with generated contents (HTML, CSS, JS) into a tarball. Testcontainers library allows to copy files from a container to the OS but not directories. That’s why we need an archive inside the SchemaSpy container.

• Spring Cloud Gateway 4.0.0-RC2 native example with Testcontainers

  7 projects | dev.to | 8 Dec 2022

  This repository provides a BuildImageTest that uses the buildpack to create a native image. It then tests the native image, using Testcontainers and JUnit. Building the native image with AOT processing, as part of a test, takes minutes not seconds, and should not be part of normal "inner loop" development. So the BuildImageTest is in a separate sourceSet and can be executed independently. This is a very powerful pattern, that I'm just getting started with. I would love to hear your thoughts on this pattern or other alternatives to it.
