+# AGENTS.md — AI Agent Instructions for OSBv2 Selenium Test Suite
+
+## Overview
+
+This directory contains end-to-end browser tests for the OSBv2 portal
+(`https://v2dev.opensourcebrain.org/`). Stack: **Python + Selenium 4 +
+pytest + Firefox/Chrome (headless by default)**. Architecture: **Page
+Object Model**.
+
+Tests target the **staging instance** (v2dev). Keycloak credentials
+required for login-dependent tests.
+
+**Key env vars** (set in `tests/.env`):
+- `OSB_USERNAME` / `OSB_PASSWORD` — Keycloak credentials (NOT `USERNAME`/`PASSWORD` — those clash with Linux system env vars)
+- `APP_URL` — `https://v2dev.opensourcebrain.org/`
+- `AUTH_METHOD` — `ui` (default) or `cookie`
+- `BROWSER` — `chrome` (default, falls back to `firefox` if Chrome not found)
+
+## Running Tests

+
+## File Map
+
+| File | Role |
+|---|---|
+| `config.py` | Env-var config. Uses `Path(__file__)` to find `.env`. **Uses `OSB_USERNAME`/`OSB_PASSWORD` — not `USERNAME`/`PASSWORD`.** |
+| `css_selectors.py` | CSS / XPath selectors. **Renamed from `selectors.py` to avoid shadowing Python stdlib `selectors`.** |
+| `conftest.py` | Fixtures: `driver` (Chrome or Firefox), `base_url`, `authenticated_user`. Firefox fallback if Chrome missing. |
+| `helpers/auth.py` | `login()`, `logout()`, `ensure_logged_in()`. `AUTH_METHOD=ui` drives Keycloak form via JS; `AUTH_METHOD=cookie` sets `kc-access` JWT cookie. |
+| `helpers/wait_conditions.py` | Custom expected conditions placeholder. |
+| **Page Objects** | |
+| `pages/base_page.py` | `BasePage` — `wait_for`, `click` (with JS fallback for obscured elements), `type_text`, `switch_to_app_frame`, `switch_to_main`. |
+| `pages/home_page.py` | Workspaces listing, tabs, sidebar nav (About/Workspaces/Repositories), create-new menu, templates, search/filter, about dialog open/close. |
+| `pages/workspace_page.py` | Workspace detail, open-with split button, actions menu (delete/clone/edit/make-public/make-private), clone snackbar handling, workspace editor form (name, visibility select, save). |
+| `pages/workspace_open_page.py` | `/workspaces/open/:id/:app` — application iframe view. |
+| `pages/repository_page.py` | `RepositoriesPage` (listing, tabs, grid/list toggle, add-repository dialog, search/filter) + `RepositoryPage` (detail, file tree, select-all, individual file click, workspace creation dialogs). |
+| `pages/user_page.py` | User profile, tabs, groups, edit profile dialog (picture URL, save, cancel). |
+| `pages/auth_page.py` | Keycloak login form page object. |
+| **Test Files** | |
+| `tests/test_auth.py` | Home page load, login, logout, round-trip, **protected route redirect**. |
+| `tests/test_about_dialog.py` | About dialog open and close. |
+| `tests/test_workspaces.py` | View public, create, view detail, delete, **clone, edit, make public, make private**. |
+| `tests/test_applications.py` | Open with NetPyNE / NWB Explorer / JupyterLab (iframe, **`@slow`**). |
+| `tests/test_repositories.py` | Listing, detail, **add repository, grid/list toggle, file tree browsing, create workspace from repo (with/without selection)**. |
+| `tests/test_user_profile.py` | Profile load, tabs, edit button, **edit profile dialog**. |
+| `tests/test_search_filter.py` | Search fields, filter popover. |
+
+## Conventions
+
+### When adding a new test
+
+1. **Add selectors to `css_selectors.py`** — never inline them. Prefer `id` attrs over MUI classes. Use XPath (`//button[contains(., "text")]`) for text-based matching — `:has-text()` pseudo-selectors are NOT valid CSS and fail in Selenium.
+2. **Use page objects** — add methods to the relevant page class.
+3. **Document flows** — every test function must have a docstring with numbered steps.
+4. **Mark slow tests** `@pytest.mark.slow` (JupyterHub server spawn, >1 min).
+5. **Mark smoke tests** `@pytest.mark.smoke` (fast, always-pass).
+6. **Use `pytest.skip()`** for optional/missing data, not hard failures.
+7. **Use unique names** — prefix with `selenium-test-{uuid_suffix}` for parallel safety.
+8. **Clean up** — creation tests should delete what they create.
+9. **Use the click() with JS fallback** — `base_page.py`'s `click()` catches `ElementClickInterceptedException` and falls back to `execute_script("arguments[0].click()")`.
+
+### Auth
+
+- **`OSB_USERNAME` / `OSB_PASSWORD`** — not `USERNAME`/`PASSWORD` (which is a standard Linux env var).
+- `authenticated_user` fixture (session-scoped, once per worker). Calls `ensure_logged_in()`.
+- `AUTH_METHOD=ui`: drives real Keycloak form via `execute_script()` to set field values + dispatch `input` events.
+- `AUTH_METHOD=cookie`: sets `kc-access` JWT cookie directly.
+- **Error detection**: The auth helper checks for "Invalid username or password" and other Keycloak error messages and raises a clear `RuntimeError`.
+- The `.env` path is resolved explicitly via `Path(__file__).resolve().parent / ".env"`.
+
+### Iframes
+
+- `<iframe id="workspace-frame">` holds the Jupyter application.
+- Use `page.switch_to_app_frame()` / `page.switch_to_main()`.
+
+### Timeouts (config.py)
+
+| Setting | Default | Meaning |
+|---|---|---|
+| `IMPLICIT_WAIT` | 15s | Element wait fallback |
+| `PAGE_LOAD_TIMEOUT` | 120s | Full page navigation |
+| `WORKSPACE_LOAD_TIMEOUT` | 600s | Application iframe readiness |
+| Auth helper waits | 120s (Keycloak), 60s (post-login redirect) | Hardcoded for slow clusters |
+
+### Parallel execution
+
+- `pytest-xdist` with `-n 2`. Session-scoped `driver` per worker.
+- Workspace names use `uuid.uuid4().hex[:8]` suffix.
+
+## Known Issues / Gotchas
+
+- **`css_selectors.py` naming**: Don't rename to `selectors.py` — shadows Python stdlib `selectors`.
+- **`:has-text()` is NOT valid CSS**: Selenium WebDriver doesn't support jQuery pseudo-selectors. Use XPath `//button[contains(., "text")]` instead.
+- **Element click intercepted**: MUI overlays obscure buttons. Fixed in `base_page.py` with JS fallback.
+- **Stale JupyterHub servers**: Clean up at `/hub/home` before running `@slow` app tests.
+- **Firefox fallback**: `conftest.py` auto-detects missing Chrome and switches to Firefox.
+- **Slow cluster**: All timeouts are set generously (120s+). If running on a faster instance, reduce `PAGE_LOAD_TIMEOUT`.
+- **Staging API (503)**: The workspace/repository/user APIs on staging may return 503 when under load. Tests that need API data gracefully `pytest.skip()`.
+- **Selenium 4 API only**: `find_element("css selector", ...)`, not the legacy `find_element_by_css_selector(...)`.

+# OSBv2 Selenium Test Suite
+
+End-to-end browser tests for the [Open Source Brain v2](https://www.v2dev.opensourcebrain.org/) web portal, built with **Python**, **Selenium 4**, **pytest**, and **Chrome**.
+
+These tests port and expand upon the existing Puppeteer e2e suite in `applications/osb-portal/test/e2e/`. The architecture follows the Page Object Model pattern for readability and maintainability.
+
+---
+
+## Quick Start
+
+```bash
+# 1. Create and activate a virtual environment
+uv venv .venv --python 3.12
+source .venv/bin/activate
+
+# 2. Install test dependencies
+uv pip install -r tests/requirements.txt
+
+# 3. Set credentials
+cp tests/.env.example tests/.env
+# Edit tests/.env with your Keycloak username and password.
+
+# 4. Run the smoke tests (no auth needed)
+pytest tests/tests/test_auth.py::TestAuth::test_home_page_loads
+
+# 5. Run all fast tests
+pytest tests/ -m smoke -n 2
+
+# 6. Run everything (including slow application-open tests)
+pytest tests/ -n 2
+```
+
+---
+
+## Configuration
+
+All settings come from environment variables. Create a `tests/.env` file for local development (this file is gitignored).
+
+| Variable | Default | Description |
+|---|---|---|
+| `APP_URL` | `https://www.v2dev.opensourcebrain.org/` | Instance under test. Must include the trailing slash. |
+| `USERNAME` | (empty) | Keycloak username for UI login. |
+| `PASSWORD` | (empty) | Keycloak password for UI login. |
+| `AUTH_METHOD` | `ui` | `ui` to drive the login form, `cookie` to bypass it. |
+| `KC_ACCESS_TOKEN` | (empty) | Pre-obtained JWT token for `AUTH_METHOD=cookie`. |
+| `PUPPETEER_DISPLAY` | (unset) | Set to any value to see the browser window (not headless). |
+| `CAPTURE_SCREENSHOTS` | `0` | Set to `1` to save screenshots of failures under `tests/screenshots/`. |
+| `PARALLEL_WORKERS` | `2` | Number of `pytest-xdist` parallel workers. |
+
+---

+```
+
+---
+
+## Authentication Modes
+
+### UI Login (`AUTH_METHOD=ui`, default)
+
+The test clicks "Sign in" on the portal header, fills the Keycloak `#username` and `#password` fields, and submits. This is the most realistic option.
+
+```bash
+USERNAME=myuser PASSWORD=mypass AUTH_METHOD=ui pytest tests/
+```
+
+### Cookie Login (`AUTH_METHOD=cookie`)
+
+Bypasses the login form entirely. Faster for iterative development, but requires a valid JWT token. Obtain one from Keycloak or your browser's DevTools (Application → Cookies → `kc-access`).
+
+```bash
+KC_ACCESS_TOKEN=eyJhbGci... AUTH_METHOD=cookie pytest tests/
+```
+
+---
+
+## Page Object Model
+
+Every page in the portal has a corresponding page object class. They all inherit from `BasePage`, which provides:
+
+| Method | What it does |
+|---|---|
+| `wait_for(by, value)` | Wait for element to be present in the DOM |
+| `wait_for_visible(by, value)` | Wait for element to be visible |
+| `wait_for_clickable(by, value)` | Wait for element to be clickable |
+| `click(by, value)` | Wait for clickable, then click |
+| `type_text(by, value, text)` | Wait for element, optionally clear, then type |
+| `switch_to_app_frame()` | Enter the `#workspace-frame` iframe |
+| `switch_to_main()` | Return from iframe to main page context |
+
+### Example: Adding a new test
+
+```python
+import pytest
+from pages.home_page import HomePage
+
+def test_my_new_feature(self, driver, base_url, authenticated_user):
+    """Descriptive docstring that explains the flow in steps."""
+    # Navigate to home
+    driver.get(base_url)
+    home = HomePage(driver)
+    home.wait_for_workspaces_list()
+
+    # Interact with the page through the page object
+    home.click_featured_tab()
+    cards = home.get_workspace_cards()
+    assert len(cards) >= 1, "Expected at least one workspace card"
+
+    # Page object methods document themselves
+    # Use selectors.py constants instead of hardcoded strings
+    from css_selectors import WORKSPACES
+    assert home.find("css selector", WORKSPACES) is not None
+```
+
+---
+
+## Pre-existing Test Data
+
+The test suite assumes certain data already exists on the staging instance:
+
+- **Smoke Test Workspace**: A workspace with `aria-label="Smoke Test Workspace"` on the "Featured" tab, used by the application-open tests.
+- **Test user account**: A Keycloak user with at least one workspace. The existing Puppeteer suite uses `simao-osb`.
+
+If these don't exist, the tests may skip or fail. Ask a team member for credentials to the staging test account.
+
+---
+
+## Troubleshooting
+
+### Tests fail with `TimeoutException` on element waits
+
+- Make sure `APP_URL` is correct and the instance is reachable.
+- Check that your test user has the expected workspaces/repositories.
+- The staging instance may be restarting or under load — retry.
+- Increase the timeout value in `config.py` if needed.
+
+### `webdriver-manager` can't find Chrome
+
+Install Chrome or Chromium on your system. If you're running in CI (GitHub Actions, etc.), use the `setup-chrome` action or equivalent.
+
+### "No workspace cards found"
+
+The home page loads differently for authenticated vs. anonymous users. Make sure the `authenticated_user` fixture runs if your test needs private workspaces.
+
+### Application-open tests timeout (10+ minutes)
+
+JupyterHub server spawning is slow. This is expected. Check that the user has no stale servers running by visiting the JupyterHub control panel (`/hub/home`) before running tests.
+
+### Stale servers blocking new sessions
+
+If the user has the maximum number of notebook servers already running, the application-open tests will fail. Visit the JupyterHub hub page and stop/delete old servers manually.
+
+---
+
+## Writing New Tests
+
+1. **Add selectors** to `selectors.py` rather than hardcoding CSS strings in test files.
+2. **Use page objects** — add new methods to existing page classes, or create new page classes under `pages/`.
+3. **Document flows** — every test function should have a docstring listing its step-by-step flow. Comment non-obvious Selenium interactions.
+4. **Mark slow tests** with `@pytest.mark.slow` so they can be filtered out for fast smoke runs.
+5. **Be tolerant of missing data** — use `pytest.skip()` rather than hard-failing when optional data isn't present.
+6. **Use unique names** for test-created workspaces (e.g. `selenium-test-{uuid}`) so parallel workers don't collide.
+7. **Clean up** — test workspace creation tests should also delete created workspaces.

+Authentication helpers for OSBv2 Selenium tests.
+
+Supports two strategies, controlled by the ``AUTH_METHOD`` config value:
+
+**ui** (default)
+    Drive the Keycloak login page — click "Sign in", fill the username and
+    password fields, submit.  This mirrors what a real user does and is the
+    most robust option.
+
+**cookie**
+    Bypass the login form by injecting a valid ``kc-access`` cookie directly
+    into the browser session.  You must provide a pre-obtained JWT token via
+    the ``KC_ACCESS_TOKEN`` environment variable.  Useful for fast local
+    iteration when you have a long-lived token.
+
+Examples
+--------
+    # UI login (default)
+    pytest tests/ -k test_login
+
+    # Cookie-based auth
+    KC_ACCESS_TOKEN="eyJhbGci..." AUTH_METHOD=cookie pytest tests/
