Testcontainers Cloud makes it easy to run reliable integration tests with real dependencies in your CI. Unlike on desktop where container images are cached throughout the duration of a developer's test session, CI jobs scale efficiently and stay fast by requesting ephemeral workers, often in parallel. So far, this meant that each worker had to pull container images before executing its tests, potentially extending jobs by up to a minute. For Testcontainers Cloud customers on a paid plan, container images now remain available in-between CI runs whenever possible, leading to faster CI pipelines when they run successively.
Note: this feature is currently in public beta, and limited to Testcontainers Cloud customers on a paid Team or Enterprise plan. Please let us know if you see any opportunity for improvement or have any questions.
