Create custom testcontainer modules?-CodePudding

I am using JUnit5 TestContainers.

I see there are TestContainer modules such as these: https://github.com/testcontainers/testcontainers-java/tree/main/modules

I would like to build my own TestContainer custom module.

Is there a way for developers to build their own?

CodePudding user response：

Yes, you can extend the GenericContainer class. By overriding methods like containerIsStarted or adding your own methods, you can customize the container's behavior.

Have a look at how these modules are implemented, e.g., the MongoDB one. It overrides containerIsStarted to initialize a replica set:

@Override
protected void containerIsStarted(InspectContainerResponse containerInfo, boolean reused) {
    if (reused && isReplicationSetAlreadyInitialized()) {
        log.debug("Replica set already initialized.");
    } else {
        initReplicaSet();
    }
}
