Struct MockProvider 

pub struct MockProvider<I, O> { /* private fields */ }

A generic mock that records calls and returns pre-configured responses.

Useful for testing code that depends on a RequestResponse-style provider without reaching real infrastructure.

Example

let mock = MockProvider::<String, u64>::new();
mock.will_return(42);

// Hand `mock` to the system under test, then verify:
assert_eq!(mock.call_count(), 1);

Implementations

impl<I: Clone + Send + Sync + 'static, O: Clone + Send + Sync + 'static> MockProvider<I, O>

pub fn new() -> Self

Create a new mock with no pre-configured responses.

pub fn will_return(&self, response: O) -> &Self

Enqueue a successful response.

pub fn will_fail(&self, err: AppError) -> &Self

Enqueue an error response.

pub fn calls(&self) -> Vec<I>

Return a clone of all recorded call inputs.

pub fn call_count(&self) -> usize

Return the number of calls recorded so far.

pub fn execute(&self, input: I) -> AppResult<O>

Record a call and pop the next response.

Panics if no response has been enqueued.

Trait Implementations

impl<I: Clone + Send + Sync + 'static, O: Clone + Send + Sync + 'static> Default for MockProvider<I, O>

fn default() -> Self

Returns the “default value” for a type.
