* Switch on/off all lights, and wait for the result
Reuses the parallel_updates semaphore.
This is a small crutch which serializes platforms which already do tis
for updates. Platforms which can parallelize everything, this makes it
go faster
* Fix broken unittest
With manual validation, with help from @frenck, we found out that the
assertions are wrong and the test should be failing.
The sequence requested is
OFF
ON
without cancelation, this code should result in:
off,off,off,on,on,on
testable, by adding a `await hass.async_block_till_done()` between the
off and on call.
with cancelation. there should be less off call's so
off,on,on,on
* Adding tests for async_request_call
* Process review feedback
* Switch gather with wait
