# E2E SDK Scenario Testing

This skill guides the design and implementation of end-to-end tests using the Python SDK.

## Goal
1.  **Verify System Correctness**: Test the full stack (SDK → API → Database).
2.  **Validate SDK Design**: Ensure the SDK is intuitive and user-friendly.

---

## Phase 1: Scenario Discovery

### 1. Identify Business Domain Features

Review the implemented features to identify testable scenarios. Map features to user workflows:

| Feature Area | User Workflow | SDK Methods |
|--------------|---------------|-------------|
| Authentication | API key management | `auth.create_api_key()`, `auth.revoke_api_key()`, `auth.get_current_user()` |
| Data Pipelines | Ingest economic data | `pipelines.submit_definition()`, `pipelines.create_instance()` |
| Experiments | Explore expressions | `experiments.create()`, `experiments.run()` |
| Signals | Register alpha signals | `signals.create()`, `signals.validate()` |
| Resources | Organize work | `resources.create()`, `resources.move()` |
| RBAC | Control access | `rbac.grant_role()`, `rbac.list_grants()` |
| Chat | Collaborate | `chat.create_channel()`, `chat.send_message()` |
| Versioning | Track changes | `refs.create_branch()`, `refs.merge()` |

### 2. Design Case Study Scenarios

Each case study should represent a **coherent business workflow**, not isolated operations.

**Good Scenario Design:**
> "Quantitative Researcher Daily Workflow: Create project, run experiment, save macro, register signal, verify audit."

**Bad Scenario Design:**
> "Test Create Resource, Test Update Resource, Test Delete Resource" (Isolated operations)

### 3. Scenario Coverage Matrix

Ensure scenarios cover all dimensions:
*   **CRUD Operations** (Create, Read, Update, Delete)
*   **Business Logic** (Validation, status transitions)
*   **Cross-Resource** (Relationships, lineage)
*   **RBAC** (Permission checks)
*   **Audit** (Activity emission)
*   **Error Cases** (Invalid inputs, permission denied)

---

## Phase 2: Infrastructure & Patterns

Refer to the following references for implementation details:

- **[references/fixtures.md](references/fixtures.md)**: Standard `conftest.py` setup and `sdk_with_tenant` patterns.
- **[references/patterns.md](references/patterns.md)**: Code templates for `TestCaseStudy` classes, CRUD workflows, and Multi-user tests.

---

## Phase 3: SDK Design Feedback

### Capture Improvement Opportunities

Create a tracking section in test files to document:
1.  **Issues Found**: Missing fields, confusing names, inconsistent behavior.
2.  **Positive Patterns**: Things that work well.

### Improvement Workflow
1.  **Document** issue in comments.
2.  **Create** minimal repro test.
3.  **Propose** fix (schema change, new helper).
4.  **Implement** fix.
5.  **Verify**.

---

## Phase 4: Running Tests

```bash
# Run all E2E tests
uv run pytest tests/e2e/ -xvs

# Run specific case study
uv run pytest tests/e2e/test_case_studies.py::TestCaseStudy1_FREDEconomicData -xvs

# Run with coverage
uv run pytest tests/e2e/ --cov=libs/sdk_py --cov-report=term-missing
```

### Maintenance Rules
*   **No Mocks**: Use real SDK → API → DB.
*   **Independent Tests**: Each test creates its own data.
*   **Clean Assertions**: Assert business outcomes.

---

## Authentication Testing Patterns

### Test Setup with Dev Auth

For E2E tests, use dev mode authentication with ASGI transport:

```python
@pytest_asyncio.fixture(scope="function")
async def sdk_client():
    """Create an AsyncPlatformClient using ASGI transport."""
    httpx_client = AsyncClient(
        transport=ASGITransport(app=app),
        base_url="http://test",
    )
    client = AsyncPlatformClient(
        base_url="http://test",
        client=httpx_client,
    )
    yield client
    await client.close()

@pytest_asyncio.fixture(scope="function")
async def auth_test_setup(sdk_client):
    """Set up tenant and principal for auth testing."""
    tenant_id = uuid4()
    principal_id = uuid4()

    sdk_client.set_principal_id(principal_id)
    sdk_client.set_tenant_id(tenant_id)

    # Create tenant (creates principal implicitly)
    await sdk_client.tenants.create(name=f"TestTenant-{tenant_id}")

    return {"client": sdk_client, "tenant_id": tenant_id, "principal_id": principal_id}
```

### API Key Testing Scenarios

| Scenario | What to Test |
|----------|--------------|
| API Key CRUD | Create, list, get, revoke |
| API Key Auth | Use key to authenticate new client |
| Key Revocation | Revoked key fails authentication |
| Multiple Keys | Multiple keys work independently |
| Key Expiry | Expired keys fail authentication |

### Example: API Key Authentication Test

```python
@pytest.mark.asyncio
async def test_authenticate_with_api_key(auth_test_setup):
    """Test authenticating with an API key."""
    client = auth_test_setup["client"]

    # Create API key with dev auth
    created = await client.auth.create_api_key(name="Test Key")
    full_key = created["key"]

    # Create new client using the API key
    api_key_client = AsyncPlatformClient(
        base_url="http://test",
        api_key=full_key,
        client=AsyncClient(
            transport=ASGITransport(app=app),
            base_url="http://test",
        ),
    )

    try:
        user_info = await api_key_client.auth.get_current_user()
        assert user_info["auth_method"] == "api_key"
    finally:
        await api_key_client.close()
```
