Issue

Closes #208

[taconi]

It needed to update the version of the poetry to 1.2.2 because there was an error that was corrected in this version, and the version of the python for 3.8.x because the flake8 was breaking (no further support for version 3.7)

@camilamaia excluding conflicts, there are some reason to don't merge this?

[camilamaia]

@uesleicarvalhoo @taconi
I was checking and there are still many downloads of ScanAPI with Python 3.7:
https://pypistats.org/packages/scanapi

I also don't want to push to a breaking change "only" because of a development package. So I am not sure what would be the best way to go here...

This is the same thing that is blocking me here: #566 🤔

Ideas?

[uesleicarvalhoo]

@camilamaia httpx is available for python 3.7 or higher, no? 🤔

[camilamaia]

@taconi I am fixing the pipelines and the dependencies. I will let you know as soon as I merge the changes :)

[camilamaia]

@taconi would you mind trying now?

[taconi]

It's giving an error in the demo-api, but I cloned this project and ran it locally and it's working with the definition of the files ./examples/demo-api/scanapi.yaml and ./examples/demo-api/scanapi.conf. I don't know what could be going on.

[camilamaia]

We can ignore the ScanAPI Examples / Demo API check. It is a problem with GitHub actions and not the code. Sorry for the inconvenience 😢 .

The other failing check is regarding this line: https://github.com/scanapi/scanapi/pull/557/files#diff-eac99bc2fbdb913fdf03fcd5f9b3cbd3583df042256d0ab1aa42a24421c621a6R172

What do you think of having more specific exceptions: https://www.python-httpx.org/exceptions/?
At least for these main four HTTPError, InvalidURL, CookieConflict, StreamError.

Thanks @taconi !!
