Postgres container that will be run only once per test suite

[Krzysztof-Lempicki]

Hi,

In my project I am using SpringBoot and Spock.

All my tests transactions are never committed.
I don't need to run container per test or test class.

How to setup postgres container that will start before first test and
will be closed after last one?

You can opt-in for container reuse feature.

1. Define container with withReuse(true)

@Shared
public GenericContainer container = new GenericContainer(SpockTestImages.HTTPD_IMAGE)
        .withExposedPorts(80)
        .withReuse(true)

2. opt-in to reuse in ~/.testcontainers.properties

testcontainers.reuse.enable=true

3. containers should be started manually using container.start(). See docs

Note
This is an experimental feature. Containers using withReuse(true) won't stop after all tests are finished.

You can create a BaseITSpecification which declares the container to be reused across your tests. Take into account that the container definition should be the same to be reused.

Besides the excellent answer by @eddumelendez, you can also make use of the Singleton Container Pattern.
