From 0a9fcd5d71099b8e466448d1e4e8c2abadc822df Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andr=C3=A9=20Schild?= Date: Fri, 24 Jul 2026 10:01:06 +0200 Subject: [PATCH 1/5] Auto-provision a Nextcloud server for integration tests via Testcontainers Integration tests previously required a manually configured Nextcloud server and were skipped otherwise, so they effectively never ran in CI. This adds a Testcontainers-based helper (NextcloudTestContainer) that starts a throw-away Nextcloud container once per JVM and exposes it via the existing nextcloud.api.test.* system properties, so the existing tests run unchanged. The behaviour is backwards compatible: - if an external server is configured (settings.xml), it is used and no container is started; - if Docker is unavailable, the properties stay unset and the tests skip silently, exactly as before. Testcontainers is pinned to 1.21.4 (test scope); the 2.x line requires Java 17, while this project targets Java 11. Also unwraps a malformed nested in the surefire plugin config, and documents both test options in README.developers.md.
