Add URL and payload validation to conversation client tests

[Copilot]

Conversation client tests only verified non-null responses without validating HTTP requests. Tests now capture and assert on request methods, URLs, query parameters, and JSON payloads.

Changes

Added request_capture fixture

• Captures HTTP requests during tests via mock transport
• Exposes last_request property for validation
• Returns standard Client instance compatible with existing APIs

Enhanced test assertions

• HTTP method validation (GET, POST, PUT, DELETE)
• Exact URL path validation including route parameters
• Query parameter validation (e.g., continuationToken)
• JSON payload validation for create/update operations (simplified to check 1 key field per test)
• Authorization header validation for token-based authentication

Added token authorization test

• New test_get_conversations_with_token validates Bearer tokens are properly sent in the Authorization header

Example

Before:

async def test_create_conversation(self, mock_http_client, mock_account):
    response = await client.create(params)
    assert response.id is not None

After:

async def test_create_conversation(self, request_capture, mock_account):
    response = await client.create(params)
    
    # Validate request
    request = request_capture._capture.last_request
    assert request.method == "POST"
    assert str(request.url) == "https://test.service.url/v3/conversations"
    
    payload = json.loads(request.content)
    assert payload["isGroup"] is True

Covers 10 methods across ConversationClient, ActivityOperations, and MemberOperations, plus token authorization.

Pull request overview

This PR enhances conversation client tests by adding validation of HTTP request details (methods, URLs, query parameters, and JSON payloads) that were previously only checking for non-null responses. A new request_capture fixture is introduced to capture and inspect HTTP requests during testing.

Changes:

• Added request_capture fixture in conftest.py to capture HTTP request details with mock transport
• Enhanced 10 test methods to validate HTTP method, URL construction, query parameters, and request payloads
• Added new test for Bearer token authorization header validation

packages/api/tests/conftest.py	Added request_capture fixture with request capturing capabilities and mock response handling
packages/api/tests/unit/test_conversation_client.py	Updated 10 test methods to use request_capture fixture and validate HTTP request details; added token authorization test

Importing modules inside test functions is an anti-pattern. The typing.Any and httpx imports should be moved to the top of the file with the other imports, especially since httpx is already imported in conftest.py and used by the request_capture fixture.

[Copilot]

This test has significant code duplication with the request_capture fixture defined in conftest.py. The RequestCapture class implementation (lines 92-106) duplicates the same class from the fixture. Instead of duplicating this code, the test should create the fixture with a custom Client that has the token configured, or extend the existing fixture to accept optional parameters.

Suggested change

	# Create request capture with the configured client
	from typing import Any
	import httpx
	class RequestCapture:
	def __init__(self):
	self.requests: list[httpx.Request] = []
	def handler(self, request: httpx.Request) -> httpx.Response:
	self.requests.append(request)
	response_data: Any = {
	"conversations": [{"id": "test", "conversationType": "personal", "isGroup": False}],
	"continuationToken": "token",
	}
	return httpx.Response(status_code=200, json=response_data, headers={"content-type": "application/json"})
	@property
	def last_request(self) -> httpx.Request | None:
	return self.requests[-1] if self.requests else None
	capture = RequestCapture()
	# Create request capture with the configured client using shared helper from conftest
	import httpx
	import conftest
	capture = conftest.RequestCapture()

The import statement is placed after several lines of code in the test function. This violates PEP 8 style guidelines where imports should be at the top of the file. Move this import to the top of the file.

The .decode("utf-8") call is unnecessary here. The json.loads() function can accept bytes directly in Python 3.6+, so this can be simplified to json.loads(last_request.content). This applies to all similar instances in this file (lines 156, 207, 234, 261).

Suggested change

	payload = json.loads(last_request.content.decode("utf-8"))
	payload = json.loads(last_request.content)

[Copilot]

The request_capture fixture duplicates response handling logic that already exists in the mock_transport fixture. Lines 244-304 in request_capture replicate the same endpoint matching and response generation as lines 46-198 in mock_transport. This duplication creates a maintenance burden where changes to mock responses must be made in two places. Consider refactoring to extract the response generation logic into a shared function that both fixtures can use, or make request_capture extend mock_transport instead of reimplementing it.
