Test support, providing the ability to run the event loop from tests.
- class traits_futures.asyncio.event_loop_helper.EventLoopHelper(event_loop)¶
Support for running the asyncio event loop in unit tests.
asyncio.AbstractEventLoop) – The asyncio event loop that this object wraps.
Dispose of any resources used by this object.
Prepare the event loop for use.
- run_until(object, trait, condition, timeout)¶
Run event loop until a given condition occurs, or timeout.
The condition is re-evaluated, with the object as argument, every time the trait changes.
traits.has_traits.HasTraits) – Object whose trait we monitor.
str) – Name of the trait to monitor for changes.
condition – Single-argument callable, returning a boolean. This will be called with object as the only input.
float) – Number of seconds to allow before timing out with an exception.
RuntimeError – If timeout is reached, regardless of whether the condition is true or not at that point.
- setattr_soon(obj, name, value)¶
Arrange for an attribute to be set once the event loop is running.
In typical usage, obj will be a
HasTraitsinstance and name will be the name of a trait on obj.
This method is not thread-safe. It’s designed to be called from the main thread.
