# HTTP Client Platform — local test topology

The suites drive these dependencies through Testcontainers and in-process fixtures, so nothing here
is required to run `./gradlew :adapter:outbound:httpclient:test`. These files exist for the nightly
lane and for reproducing a failure locally with the same images and ports CI uses.
