Having trouble setting up a development environment

Development
1

Hi,
Iḿ trying to create a pull request for a new cover-template, to combine multiple cover switches into one. It works for my setup now, so I thought I’d contribute my code.
I’m running into problems when I try to run tests… my own tests fail (obviously since I haven’t gotten round to filling them out :wink: ) but when I just checkout the development branch, without my code ‘tox’ also fails, with typing errors: “ERROR: typing: commands failed”

What am I missing here ? Where are the logs ?

When I run the last command shown on my screen
/home/timt/HomeAssistanttest/home-assistant/.tox/typing/bin/mypy --silent-imports homeassistant
I get the folllowing message
homeassistant/util/unit_system.py:108: error: misplaced type annotation

Currently on a Centos 7 system, a clone of the main github repo, on develop branch

Suggestions welcome.

Did you run script/setup?

3

Just run tests using py.test tests/

4

Yes, followed the instructions I found here: https://home-assistant.io/developers/development_environment/

Took me a couple of tries before that went smoothly, then, once I’d figured out the correct procedure (which involved setting locale correctly, the setup script went smoothly.

5

That also fails, complaints about a missing pydispatch, which pip3 claims is installed
That error seems to originate somewhere in the pytest configuration.

Thing is, when using tox, the tests run fine; tox fails at the typing phase.

I’m currently not on a very usable connection, I’ll capture the output tomorrow

6

Running tox also fails for me on the same error. All the other tests work without issues, so my dev environment is otherwise working as expected

Ok… that took a bit longer than expected… This is edited output of the current (641ba014f2f4310833f866ddbc5b1012aa135407) dev branch

This is the offending method in homeassistant/util/unit_system.py

    def length(self: object, length: float, from_unit: str) -> float:
        """Convert the given length to this unit system."""
        if not isinstance(length, Number):
            raise TypeError('{} is not a numeric value.'.format(str(length)))

        return distance_util.convert(length, from_unit,
                                     self.length_unit)  # type: float

The last line is line 108…
Removing the # type: float annotation brings to light a lot of other missing type errors, in other code.

I’m not familiar with tox; can anybody give me a hint on how to disable these type tests ?

I have exactly the same issue. Did you finally solve it or should we just ignore it?

9

I decided to ignore it, and concentrate on getting my own code working, running only the tests for my code.
(And then I got seriously sidetracked… Still have to finish this project.)

10

Did you ever manage to resolve this?
I’m having that same issue… tox fails on typing tests, log extracts below.

I followed the instructions on https://developers.home-assistant.io/docs/en/development_environment.html

What I’ve tried:

  • running my tests towards the intact dev branch, as is, without doing any changes
  • running as a user
  • running as user with sudo
  • running as root
  • tried on Ubuntu 18.04 WSL, AND Ubuntu Server 18.04 x86

Nope, never resolved this or finished the project. Discovered that I could group covers through an existing template, which works fine for me, so I lost interest…

Sorry I can’t help
