Error while running webthing-tester

I'm getting the following error while trying to run webthing-tester:

What is the right way to run the webthing tester?

[mrstegeman]

You ran it right, but I've never used it on Windows, so maybe that's the issue?

By the way, this is not a generic test script. It was written to test specific examples from our various webthing-X libraries.

[maliknaik16]

@mrstegeman Thanks for the reply.

I've implemented the webthing library in PHP and I was testing it.

[mrstegeman]

Oh, cool! The test script here should be used to test the "Single Thing" example, or the lamp device of the "Multiple Things" example.

If you have Docker available, you should be able to get this script running really easily in a python:3.7 Docker container.

[maliknaik16]

Ok, then I'll try to run this script using docker.

Thanks.

I've tried to run this script on Linux Mint with Python 3.7 but I got the following error:

Traceback (most recent call last):
  File "test-client.py", line 562, in <module>
    exit(run_client())

Seems like you can't route to your web thing. There are some command line arguments you can use. Run ./test-client.py -h to see.

In particular, you'll probably need to use --host and --port.

[maliknaik16]

@mrstegeman Thanks for the reply.

Now I'm able to run the script on Linux.

[mrstegeman]

Great!

By the way, are you interested in having your library added to the bottom of this page?

[maliknaik16]

Yeah! I'm interested in having my library added there.

Thanks for opening an issue.
