Reusable Containers (Experimental)
Reusable Containers is still an experimental feature and the behavior can change. Those containers won't stop after all tests are finished.
The Reusable feature keeps the containers running and next executions with the same container configuration
will reuse it. To use it, start the container manually by calling
start() method, do not call
directly or indirectly via
JUnit integration, and enable it manually through an
opt-in mechanism per environment. To reuse a container, the container configuration must be the same.
Reusable containers are not suited for CI usage and as an experimental feature not all Testcontainers features are fully working (e.g., resource cleanup or networking).
How to use it
~/.testcontainers.properties, by adding
- Define a container and subscribe to reuse the container using
GenericContainer container = new GenericContainer("redis:6-alpine") .withExposedPorts(6379) .withReuse(true)
- Start the container manually by using
Reusable Container with Testcontainers JDBC URL
If using the Testcontainers JDBC URL support
the URL must follow the pattern of
TC_REUSABLE=true is set as a parameter of the JDBC URL.
