Let's write intricate simulators!
Makes testing a pain as need to be patched out. Better to wrap an instance of async_chat and call methods on that. An instance can probably be passed in through...
This is from a question asked by Tom Willemsen. If a device is defined like this: ```python class MyDevice(StateMachineDevice): def initialize_data(self): self.channels = {1 : Channel(), 2 : Channel(), 3...
Class attributes can be a bit dangerous in Python. They have behaviour that **appears** very similar to instance attributes **most** of the time, but work very differently under the hood...
The `check_limits` decorator that was introduced in #157 has a few shortcomings. In its current form it can only be used on class methods with one numeric parameter. However it...
Currently, exception handling is very ad hoc throughout the system. The following exception classes exist: - `StateMachineException` (statemachine.py) - `RemoteException` (control_client.py) - `ProtocolException` (control_client.py) The latter two are probably fine...
The disambiguation term `Interface` was introduced rather hastily during the communication layer redesign and 1.0 release. Consequently, a lot of back-end code still uses incorrect terminology. This should be updated...
`SimulatedChopper` should have some unit tests. I think what we need to test is that the properties change the context in the way we expect. Maybe testing the state machine...
Due to being YAML, the protocol parameters are very sensitive to whitespace (or lack thereof) and other quirks of the standard. If the entered syntax does not parse correctly, the...
This came up while reviewing #259. Currently, Lewis requires this sort of layout for a custom device directory: ``` /some/host/path
At ISIS we have legacy drivers that talk to devices that are connected via a serial port. For testing purposes it would be useful to write an emulator that these...
