From 0eff5881be4ce80eb0a78abd559acbd9647d460a Mon Sep 17 00:00:00 2001 From: abhizipstack Date: Wed, 1 Apr 2026 12:07:09 +0530 Subject: [PATCH 01/12] fix: fix Minimal Tests workflow for OSS repo structure - Fix setup-python action: point cache to backend/uv.lock, run uv sync from backend/ directory - Simplify workflow: single pytest run from backend/ with DB-excluding markers instead of two separate test suites - Set working-directory: backend as default for all run steps - Remove reference to non-existent ./visitran_backend directory - Keep pre-commit step until pre-commit.ci is active - SonarCloud scan runs from root with project properties Co-Authored-By: Claude Opus 4.6 (1M context) --- .github/actions/setup-python/action.yaml | 7 +- .github/workflows/core-backend-tests.yaml | 133 +++++++++++----------- 2 files changed, 71 insertions(+), 69 deletions(-) diff --git a/.github/actions/setup-python/action.yaml b/.github/actions/setup-python/action.yaml index bb919515..2dcc4471 100644 --- a/.github/actions/setup-python/action.yaml +++ b/.github/actions/setup-python/action.yaml @@ -1,5 +1,5 @@ name: 'Setup Python' -description: 'Prints a greeting message' +description: 'Sets up Python, uv, and installs backend dependencies' inputs: python-version: required: true @@ -16,7 +16,8 @@ runs: with: python-version: ${{ inputs.python-version }} enable-cache: true -
