# GmRelay E2E Tests
This directory contains end-to-end tests that run **locally** against real Telegram infrastructure and the GmRelay Web dashboard. They are intentionally **not part of CI** because they require:
This module contains locally-run end-to-end tests for the GmRelay Telegram bot and Blazor/Web dashboard.
It is deliberately **not** wired into CI because it requires real Telegram infrastructure (MTProto user client) and a running Web instance.
- a real Telegram test user account;
- `api_id` / `api_hash` from https://my.telegram.org;
- a pre-authenticated MTProto session;
- a running PostgreSQL, GmRelay.Bot, and GmRelay.Web.

## `telegram_init_data.py`
A small Python helper that produces Telegram Mini App `initData` and Login Widget payloads with valid HMAC-SHA256 signatures. It mirrors `GmRelay.Shared.Telegram.TelegramAuthPayloadBuilder`.
Use it to open the Blazor/Mini App dashboard in Playwright without logging into Telegram:
```python
from helpers.telegram_init_data import build_mini_app_init_data
init = build_mini_app_init_data(
bot_token="YOUR_BOT_TOKEN",
telegram_id=424242,
first_name="Test",
username="tester")
await page.goto(f"https://localhost:8080/#tgWebAppData={init.init_data_raw}")
```
## C# equivalent
For tests inside the solution, use `GmRelay.Shared.Telegram.TelegramAuthPayloadBuilder`:
```csharp
var init = TelegramAuthPayloadBuilder.BuildMiniAppInitData(
botToken: "YOUR_BOT_TOKEN",
telegramId: 424242L,
firstName: "Test",
username: "tester");
// init.InitDataRaw is a valid initData string.
```
## Running the helper tests
## Install dependencies
```bash
cd tests/e2e/helpers
python -m pytest test_telegram_init_data.py -v
python -m venv .venv
source .venv/bin/activate # Windows: .venv\Scripts\activate
pip install -r tests/e2e/requirements.txt
playwright install chromium
```

## Run Playwright dashboard tests
1. Start the Web dashboard (and PostgreSQL) locally. The fastest way:
```bash
dotnet run --project src/GmRelay.AppHost/GmRelay.AppHost.csproj
```
2. Export environment variables that match the running Web instance:
```bash
export GMRELAY_E2E_BASE_URL="http://localhost:8080"
export GMRELAY_E2E_BOT_TOKEN="<same-token-as-web>"
export GMRELAY_E2E_TELEGRAM_ID="9000000001"
export GMRELAY_E2E_DATABASE_URL="Host=localhost;Database=gmrelay;Username=postgres;Password=<password>"
```
3. Run the tests:
```bash
python tests/e2e/dashboard/test_dashboard_auth_and_sessions.py
```
## What the dashboard tests cover
- `test_dashboard_authenticates_and_shows_groups`
Builds a valid Mini App initData payload, posts it to `/auth/telegram-webapp`, and verifies that the Blazor home page renders the authenticated greeting.
- `test_dashboard_session_edit_flow`
Seeds a player, group, and session directly in PostgreSQL, opens the group details page, clicks through to the session editor, changes the title, and asserts the updated title appears on the page.
## Notes
- Authentication is mocked using `helpers/telegram_init_data.py`, which mirrors `GmRelay.Shared.Telegram.TelegramAuthPayloadBuilder`.
- The Web instance validates HMAC-SHA256 with the same bot token, so the test payload is indistinguishable from a real Telegram Mini App payload.
- For headful debugging, change `headless=True` to `headless=False` in the test file.
