I have a question about Python libraries and testing scope.
If I'm importing 'serial' in my library, and use it like the following to create a connection to a sensor:
--- start code ---
import serial
class Sensor:
def __init__(self, serial_device):self.__serial_device = serial_device
try:
self.__connection = serial.Serial(
port=serial_device,
baudrate=9600,
bytesize=serial.EIGHTBITS,
parity=serial.PARITY_NONE,
stopbits=serial.STOPBITS_ONE,
)except serial.SerialException:
print("Could not establish serial connection to sensor")--- end code ---
how much testing should I do around the serial connection? Just mock up a few buffers (byte streams), and see how my class handles unexpected input?
One the one hand, I want to make the library as solid as possible. On the other hand, I don't want to run tests on code I don't control (the library module). I know of the 'mock-serial' utility, but haven't used it.
The aim is to make a Python version of my Arduino library for the CozIR Ambient CO2 sensor:

@simulo In general, my typing speed is rarely the bottleneck of my dev. Perhaps that's because I type at a pretty reasonable pace, and I use languages with very low amounts of boilerplate (and where nearly any boilerpoint can be abstracted away) and in the rare places where there are boilerplate (srfi-9 records come to mind) I have editor support to make typing them in fast through yasnippet.
In general, typing speed tends to correspond to the rate at which I can think, and a lot of the pauses come from needing to get up, pace around, think about the problem, get some tea, sit down again after a revelation. Or playing around with the idea iteratively and discovering the solution.
Lots of people are talking about LLMs as typing assistants and I just generally don't feel like that's a thing I need (excepting the RSI aspects; I do think more voice-driven editor piloting would be a good option to use sometimes)

La combinazione dei due fa sì che agli occhi degli astronauti arrivi praticamente solo la luce visibile.
Il rivestimento d’oro è così efficace che è stato regolarmente adoperato sia nelle tute russe sia in quelle americane e verrà usato anche nelle nuove tute Axiom per le missioni Artemis.
