+# Test Framework for typespec-python
+
+This document describes the test framework used in the `typespec-python` package
+and how it relates to the upstream
+[`http-client-python`](https://github.com/microsoft/typespec/tree/main/packages/http-client-python)
+package in the typespec repository.
+
+## Overview
+
+The test framework is a **dual-flavor testing system** (Azure and Unbranded) built
+on **pytest** and **tox**. Tests run against a mock API server
+([tsp-spector](https://github.com/microsoft/typespec)) that serves TypeSpec-defined
+HTTP endpoints on `localhost:3000`.

+
+## Test Flavors
+
+| Flavor | Core library | Credential class | What it tests |
+|--------|-------------|-----------------|---------------|
+| **azure** | `azure.core` | `AzureKeyCredential` | Azure SDK conventions, ARM resources, LRO, paging |
+| **unbranded** | `corehttp` | `ServiceKeyCredential` | Non-Azure SDK generation without Azure branding |
+
+When tests run:
+- **Azure**: `pytest mock_api/azure mock_api/shared` with `FLAVOR=azure`
+- **Unbranded**: `pytest mock_api/unbranded mock_api/shared` with `FLAVOR=unbranded`
+
+The `shared/` tests run for **both** flavors. Root `conftest.py` uses `core_library()`
+to dynamically import the appropriate core library.
+
+## Running Tests
+
+```bash
+cd packages/typespec-python/tests
+
+# Run Azure flavor tests
+tox -e test-azure
+
+# Run Unbranded flavor tests
+tox -e test-unbranded
+
+# Run all CI checks for a flavor (tests + lint + type checking)
+tox -e ci-azure
+tox -e ci-unbranded
+```
+
+### Available tox Environments
+
+| Environment | Description |
+|------------|-------------|
+| `test-azure` / `test-unbranded` | Run pytest integration tests |
+| `lint-azure` / `lint-unbranded` | Run pylint |
+| `mypy-azure` / `mypy-unbranded` | Run mypy type checking |
+| `pyright-azure` / `pyright-unbranded` | Run pyright type checking |
+| `docs-azure` / `docs-unbranded` | Build API docs with Sphinx |
+| `ci-azure` / `ci-unbranded` | All checks combined |
+
+## Key Components
+
+### Mock API Server
+
+Tests rely on `tsp-spector` to serve TypeSpec-defined mock endpoints. The root
+`conftest.py` starts the server automatically at session start and tears it down
+after all tests complete. The server runs on `localhost:3000`.
+
+### Generated Packages
+
+Each test spec produces a generated SDK package under `tests/generated/{flavor}/`.
+Before tests run, `install_packages.py` installs all generated packages into the
+test environment using `uv pip install --no-deps`.
+
+### Async Tests
+
+Every `test_*.py` in the sync directory has a corresponding `test_*_async.py` in
+`asynctests/`. Async fixtures use `@pytest_asyncio.fixture` and `pytest.ini`
+configures `asyncio_mode = auto`.
+
+## Folder Mapping to the typespec Repository
+
+The test files are shared with the upstream
+[`http-client-python`](https://github.com/microsoft/typespec/tree/main/packages/http-client-python)
+package. The **typespec repo is the source of truth** for shared test files.
+
+### Path Mapping
+
+| typespec repo | autorest.python repo |
+|--------------|---------------------|
+| `packages/http-client-python/tests/mock_api/azure/` | `packages/typespec-python/tests/mock_api/azure/` |
+| `packages/http-client-python/tests/mock_api/shared/` | `packages/typespec-python/tests/mock_api/shared/` |
+| `packages/http-client-python/tests/mock_api/unbranded/` | `packages/typespec-python/tests/mock_api/unbranded/` |
+| `packages/http-client-python/tests/requirements/` | `packages/typespec-python/tests/requirements/` |
+| `packages/http-client-python/eng/scripts/ci/regenerate-common.ts` | `packages/typespec-python/eng/scripts/regenerate-common.ts` |
+
+### What Is Synced
+
+The script `eng/scripts/sync_from_typespec.py` copies from typespec → autorest.python:
+
+1. **`regenerate-common.ts`** — shared regeneration logic
+2. **Requirements files** — `azure.txt` and `unbranded.txt` (marker-delimited
+   common sections are synced; repo-specific deps like `geojson` are preserved)
+3. **Test files** — all files under `mock_api/{shared,azure,unbranded}` except:
+   - `conftest.py` (each repo has its own)
+   - `tox.ini`, `requirements.txt`, `dev_requirements.txt`
+   - `.pyc` files
+
+### What Is NOT Synced
+
+| Item | Reason |
+|------|--------|
+| `conftest.py` files | Different server startup and fixture logic per repo |
+| `tests/mock_api/shared/unittests/` | Repo-specific unit tests |
+| `tests/generated/` | Regenerated independently in each repo |
+| `tests/unit/` (typespec only) | Internal to http-client-python |
+| `pytest.ini`, `tox.ini` | Different CI configurations per repo |
+
+### Requirements Marker Convention
+
+Requirements files (`azure.txt`, `unbranded.txt`) use markers to delimit the
+common section synced between repos:
+
+```
+# === common azure dependencies across repos ===
+# Azure SDK dependencies
+-r base.txt
+azure-core>=1.37.0
+azure-mgmt-core==1.6.0
+# === end common azure dependencies across repos ===
+geojson>=3.0.0          # <-- autorest.python-only dependency, outside markers
+```
+
+Dependencies outside the markers are preserved during sync.
+
+### Sync Workflow
+
+The sync is run automatically as part of [pipeline](https://dev.azure.com/azure-sdk/internal/_build?definitionId=7257), or manually:
+
+```bash
+python eng/scripts/sync_from_typespec.py <path-to-typespec-repo>
+```
