Easy Integration Testing with Spring Boot + Test Containers

Integration tests require external resources such as databases, message queues ....  to execute successfully.  A developer must consults the project's development environment setup guide to install and configure the various dependencies that integration tests require before they can run the integration tests, this is error prone and time consuming. CI/CD pipelines are significantly complicated by the shared external dependencies and frequently integration tests fail because the external dependencies are not properly configured. The environment setup complexity of integration tests leads to a small number of integration tests. What if Integration testing was just as easy as unit testing?  Would you do more of it on your project?

"Testcontainers is a Java library that supports JUnit tests, providing lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container" (testcontainers.org).

This workshop is a hands-on introduction to using testing containers with Spring Boot + Junit5 + Testcontainer to make integration testing easy. You will be provided with many sample applications that demonstrate how Test Containers make integration testing very easy.
