Struct AsyncTestHarness 

pub struct AsyncTestHarness;

A test harness for async operations with controllable time

Implementations

impl AsyncTestHarness

pub fn new() -> Self

Create a new test harness

pub fn execute_command<M: Message + Clone + Send + 'static>( &self, cmd: Cmd<M>, ) -> Vec<M>

Execute a command and collect all messages it produces

pub fn execute_tick_now<M: Message, F>(&self, _duration: Duration, f: F) -> M

where F: FnOnce() -> M,

Execute a tick command immediately (for testing)

pub fn block_on_async<M: Message + Send + 'static>( &self, future: impl Future<Output = Option<M>> + Send + 'static, ) -> Option<M>

Execute an async future and wait for result

pub fn execute_and_wait<M: Message + Clone + Send + 'static>( &self, cmd: Cmd<M>, wait_duration: Duration, ) -> Vec<M>

Execute a command and wait for completion
