Overview

Mock Brave Search API response JSON for the query "What is Semantic Kernel", used as test fixture data in the Plugins unit tests of the Semantic Kernel .NET SDK.

Description

This JSON file contains a captured Brave Search API response for the query "What is Semantic Kernel". It serves as a mock response fixture for unit testing the Brave search plugin integration. The Brave Search API response structure differs significantly from Bing and Google, using a distinct schema with query, mixed, and web sections.

Key elements of the response:

query - Contains metadata about the search query including original text, is_navigational, is_news_breaking, spellcheck_off, country, and location fields
mixed - Defines the ordering and layout of mixed search results with type/index pairs indicating how web results should be interleaved
web - Contains the actual web search results (referenced by the mixed section via index)
Each web result includes: title, url, description, and additional metadata
The query section includes flags for bad_results, should_fallback, and more_results_available

This fixture validates that the Brave search plugin correctly handles the Brave-specific API response format, which is structurally distinct from both Bing and Google responses.

Usage

This file is loaded during Plugins unit test execution to mock Brave Search API responses. It enables tests to validate Brave-specific response parsing, mixed result ordering, and web result extraction without requiring a live Brave Search API key. Developers adding or maintaining the Brave search plugin use this fixture for deterministic testing.

Inputs

Name	Type	Required	Description
original	string	yes	The original search query text (e.g., "What is Semantic Kernel")

Outputs

Name	Type	Description
query	object	Query metadata including original text, navigational flags, country, and quality indicators
query.is_navigational	boolean	Whether the query is navigational in nature
query.more_results_available	boolean	Whether additional result pages are available
mixed	object	Layout definition specifying how different result types should be ordered
mixed.main	array	Array of type/index pairs defining result ordering
web	object	Web search results section containing the actual result entries

Usage Examples

Mocking a Brave Search Response

// Example: Using the mock data to test the Brave search plugin
var mockJson = File.ReadAllText("TestData/brave_what_is_the_semantic_kernel.json");

var handler = new MockHttpMessageHandler(mockJson, HttpStatusCode.OK);
var httpClient = new HttpClient(handler);

var bravePlugin = new BraveSearchPlugin(httpClient, "test-api-key");
var results = await bravePlugin.SearchAsync("What is Semantic Kernel");

Assert.NotEmpty(results);
// Verify the Brave-specific mixed result ordering is handled
Assert.True(results.Count() > 0);
