From e455f71d07954cb7721615a0a7ab5a953735b60d Mon Sep 17 00:00:00 2001 From: Bretton Date: Wed, 05 Nov 2025 03:25:00 +0000 Subject: [PATCH] test(integration): add comprehensive comment consumer tests Add 20 integration tests covering all comment indexing scenarios: Core operations: - Create comment (normal, idempotent, out-of-order) - Update comment (content, metadata) - Delete comment (soft delete) Threading: - Root/parent references - Reply count updates - Thread hierarchy queries Security: - Invalid DID rejection - Content length limits - Malformed AT-URI rejection - Threading immutability (reject mutation attempts) Out-of-order handling: - Child arrives before parent (count reconciliation) - Multiple children before parent Resurrection: - Recreate deleted comment (same parent) - Recreate deleted comment (different parent - tests threading ref updates) Repository queries: - ListByRoot, ListByParent, ListByCommenter - Soft delete filtering All tests verify both database state and denormalized counts. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- tests/integration/comment_consumer_test.go | 1763 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file(s) changed, 1763 insertion(s)(+), 0 deletion(s)(-) diff --git a/tests/integration/comment_consumer_test.go b/tests/integration/comment_consumer_test.go new file mode 100644 --- /dev/null +++ b/tests/integration/comment_consumer_test.go @@ -0,0 +1,1763 @@ +package integration + +import ( + "Coves/internal/atproto/jetstream" + "Coves/internal/core/comments" + "Coves/internal/db/postgres" + "context" + "fmt" + "testing" + "time" +) + +func TestCommentConsumer_CreateComment(t *testing.T) { + db := setupTestDB(t) + defer func() { + if err := db.Close();
