smithy-http

This package provides primitives and interfaces for http functionality in tooling generated by Smithy.

---

Testing

The smithy_http.testing module provides shared utilities for testing HTTP functionality in smithy-python clients.

MockHTTPClient

The MockHTTPClient allows you to test smithy-python clients without making actual network calls. It implements the HTTPClient interface and provides configurable responses for functional testing.

Basic Usage

from smithy_http.testing import MockHTTPClient

# Create mock client and configure responses
mock_client = MockHTTPClient()
mock_client.add_response(
   status=200,
   headers=[("Content-Type", "application/json")],
   body=b'{"message": "success"}'
)

# Use with your smithy-python client
config = Config(transport=mock_client)
client = TestSmithyServiceClient(config=config)

# Test your client logic
result = await client.some_operation({"input": "data"})

# Inspect what requests were made
assert mock_client.call_count == 1
captured_request = mock_client.captured_requests[0]
assert result.message == "success"

Utilities

• create_test_request(): Helper for creating test HTTPRequest objects
• MockHTTPClientError: Exception raised when no responses are queued
