Full test infrastructure, code audit fixes, and real E2E integration tests
Test infrastructure: - Django standalone test runner (pytest-django, test settings, EmailUser model) - React unit tests via Vitest with jsdom, jest compat layer, path aliases - Playwright E2E tests using generated hooks in a real Chromium browser - Docker Compose test backend (Django + Redis) for integration testing - Desktop integration test app (PyWebView + Django + uvicorn) - Makefile with test/test-django/test-react/test-integration targets Library bugs found and fixed: - hasJWT truthiness: undefined !== null was true, skipping session init - process.env crash: CSR client referenced process.env in non-Node browsers - baseUrl not forwarded: DjareaProvider didn't pass baseUrl to CSR client - Relative URL handling: new URL() failed with relative base paths - call() race condition: HTTP requests fired before CSRF cookie was set - Session init await: added sessionRef promise so call() waits for session - path_prefix on schema export: both export commands failed with URL reverse - NullBooleanField removed: referenced field doesn't exist in Django 5.0+ - lru_cache on JWT settings: get_settings() now cached as intended - Channel message routing: broadcasts now include channel name and params - httpFunctionCall: fixed URL and request body format Generator fixes: - Removed 1,100 lines of REST/OpenAPI client generation (not part of Djarea) - Generator now works for djarea-only projects without django-ninja REST APIs - Generated DjangoContext now includes ChannelProvider when channels exist - Fixed env var passthrough for schema export commands - Deduplicated fetch logic into single runDjangoCommand helper Test quality: - Fixed 33 tautological Django tests with real assertions - Found hidden bug: benchmark functions were never registered - Found hidden bug: unicode lookalike test used plain ASCII - Deleted worthless React unit tests (duplicates, shape checks, Zod-tests-Zod) - Replaced jsdom integration tests with Playwright browser tests Example apps: - example/: Integration test backend with 33 server functions, 5 forms, 4 channels covering auth variations, contexts, class-based ServerFunction, error codes, DjareaFormMixin, formsets, and JWT - desktop/: PyWebView desktop app with file system access, SQLite CRUD, system introspection, and 39 real HTTP integration tests Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
