From 7709f736e21c502224985ee154a3a5f2e446ab87 Mon Sep 17 00:00:00 2001 From: HiranoMasaaki Date: Sun, 15 Feb 2026 10:11:13 +0000 Subject: [PATCH] fix: stabilize E2E tests and add parallel CI workflow for release PRs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Fix create-expert race condition: replace describe.concurrent with sequential execution to prevent afterEach from deleting other test's temp directories - Fix published-expert assertion: add "required" to error message regex to match PERSTACK_API_KEY validation error - Fix streaming event ordering: remove strict start→stream→complete sequence assertions that fail across multiple LLM steps - Fix OpenAI reasoning token assertions: accept thinking text as alternative to token counts (o3-mini may not surface counts) - Restructure E2E workflow: split into 4 parallel matrix suites (cli-core, cli-reasoning, cli-streaming, create-expert) with concurrency 1 to avoid LLM rate limits, triggered only on changeset release PRs Co-Authored-By: Claude Opus 4.6 --- .github/workflows/e2e.yml | 50 ++++++++++++++++++++--- e2e/create-expert/create-expert.test.ts | 17 ++------ e2e/perstack-cli/published-expert.test.ts | 2 +- e2e/perstack-cli/reasoning-budget.test.ts | 26 ++++++------ e2e/perstack-cli/streaming.test.ts | 16 ++++---- 5 files changed, 69 insertions(+), 42 deletions(-) diff --git a/.github/workflows/e2e.yml b/.github/workflows/e2e.yml index 4245c83e..9d3a950a 100644 --- a/.github/workflows/e2e.yml +++ b/.github/workflows/e2e.yml @@ -1,12 +1,15 @@ name: E2E Tests on: -
