e2e: full flow with simulated externals (sign in → create project → editor)

[manuelkiessling]

Summary

Adds a full end-to-end test that covers the core flow (sign in → create project → use editor) with all external dependencies simulated. The test is deterministic and requires no real APIs, git remotes, or GitHub access.

What’s in scope

• Project creation checks: LLM key (already simulated via LLM_CONTENT_EDITOR_SIMULATE), manifest URL, and S3 credentials are validated by test doubles that accept valid-looking input without calling external services.
• Project source: Instead of cloning a real repo, the test uses a SimulatedGitAdapter that “clones” from a local fixture (tests/fixtures/e2e-workspace-template) and does a no-op on push.
• Chat/editor: Commits and PRs are handled by SimulatedGitHubAdapter (constant fake PR URL) and simulated push; no real git push or GitHub API calls.
• Workspace setup: In test env, setup steps are replaced by E2eNoOpProjectSetupStepsProvider (single true step) so setup finishes quickly without npm/mise.

Changes

• Test doubles (active only when APP_ENV=test):

  • SimulatedRemoteManifestValidator – accepts any non-empty http(s) manifest URL.
  • SimulatedS3AssetUploader – verifyCredentials() returns true; upload() returns a deterministic fake URL.
  • SimulatedGitAdapter – clone copies fixture + git init + one commit; push is no-op; other operations delegate to real git.
  • SimulatedGitHubAdapter – findPullRequestForBranch() returns null; createPullRequest() returns a constant fake PR URL.
  • E2eNoOpProjectSetupStepsProvider – single no-op setup step so workspace setup completes without running npm/mise.

• Config: when@test in config/services.yaml wires the above; e2e.workspace_fixture_path points at the fixture. docker-compose.e2e.yml sets APP_ENV: test for the messenger service so async workspace setup uses the same doubles.

• E2E fixture: tests/fixtures/e2e-workspace-template/ with minimal package.json and index.html for the simulated “clone”.

• E2E selectors: data-test-id / data-test-class added to project list, project form, editor, and workspace setup templates for stable selectors.

• New spec: tests/End2End/tests/full-flow.spec.ts – one test that signs in, creates a project (with fake data), opens the editor, waits for setup when needed, and sends one message.

How to run

mise run tests:e2e

Runs the full Playwright suite (including the new full-flow test) against the stack started with docker-compose -f docker-compose.yml -f docker-compose.e2e.yml.

Notes

• No production code paths are changed; simulations are only active when APP_ENV=test.
• Prefab projects created for the e2e user are allowed; the test asserts at least one project list item after create.
