Struct MockLlmClient 

pub struct MockLlmClient { /* private fields */ }

Supports:

• Predefined responses
• Tool call simulation
• Streaming simulation
• Call tracking
• Error injection

Implementations

impl MockLlmClient

pub fn new() -> Self

Create a new empty mock client (call with_response() to add responses)

pub fn with_responses_vec(responses: Vec<&str>) -> Self

Create a new mock client with simple text responses

pub fn from_mock_responses(responses: Vec<MockResponse>) -> Self

Create a mock client with detailed responses

pub fn from_tool_call(tool_name: &str, args: Value) -> Self

Create a mock client that calls a specific tool

pub fn with_tool_then_text( tool_name: &str, args: Value, final_response: &str, ) -> Self

Create a mock client that calls a tool then responds with text

pub fn with_response(self, text: &str) -> Self

Add a text response to the chain

pub fn with_tool_call(self, tool_name: &str, args: Value) -> Self

Add a tool call response to the chain

pub fn error_on_call(self, call_index: usize) -> Self

Set the client to error on a specific call index

pub fn fail_on_call(&self, call_index: usize)

Set the client to fail on the nth call (0-indexed)

pub fn call_count(&self) -> usize

Get the number of calls made

pub fn get_calls(&self) -> Vec<ChatRequest>

Get a copy of all calls made

pub fn last_call(&self) -> Option<ChatRequest>

Get the last call made

pub fn clear_calls(&self)

Clear call history
