# !DISCLAIMER!: I don't take credit for this script because it's mostly AI genereated. Tests are broken anyway.
# Runs E2E tests inside the ephemeral VM (or locally with --local).

# Usage:
#   CI:    REPO_URL=... COMMIT_SHA=... API_URL=... bash e2e-test.sh
#   Local: bash e2e-test.sh --local [--api-url http://10.0.2.2:3001/api]
#
# Environment variables (CI mode):
#   REPO_URL   - Gitea repo clone URL
#   COMMIT_SHA - Commit to checkout
#   API_URL    - Backend API URL
