From e3e1faece662c71419630efc622307069a850bba Mon Sep 17 00:00:00 2001 From: Admin Pupkin Date: Fri, 12 Jun 2026 21:59:32 +0300 Subject: [PATCH] test-cookbook-apply-patches-e2e: 4 integration tests for the cookbook helper MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extracts the cookbook_apply_patches function from src/cook/script.rs and runs it against the real kf6-karchive source + migration patch. Verifies the end-to-end flow that C-7 step 2 relies on: 1. First apply: helper applies the patch via `git apply` from inside ${COOKBOOK_SOURCE}, reports `applying 01-initial-migration.patch` and `applied=1 skipped=0 failed=0`. 2. Idempotency: running the helper a second time detects the patch is already applied via `git apply --reverse --check` and reports `already applied, skipping`. 3. Post-patch source state: the helper actually modifies the source — verifies that `ecm_install_po_files_as_qm` is now commented out (line starts with `#`) in the source after the helper runs. 4. 4-level path resolution: verifies that the `${COOKBOOK_RECIPE}/../../../../local/patches/` path used in the recipe's [build].script resolves to the actual patches dir `local/patches/kf6-karchive`. These tests use a real pristine/source/patch fixture (not mocks) and run the actual cookbook helper extracted from src/cook/script.rs. Any change to the helper's behavior (path handling, idempotency check, git apply flags) is caught by these tests.
