Expected behavior

It should successfully run through the file.

Actual behavior

It instead produced the following error message:

Traceback (most recent call last):

    i['url'] = url_for("api.Entity:post", id=str(self.id), _external=True)

Could indeed be that testrun.py is outdated (unfortunate, I know); I need to check this. Have you had trouble running the app itself?

I just encountered this myself.

Architectural question?

Is there an architectural question here? Is the proper approach:

1. To dummy up a Flask app context?
2. try -block the url_for() calls which rely on it?

Feeds don't operate with Flask context, do they? It doesn't look like this test script is doing anything more than attempting to print out entity info. Specifically, it is calling .info().

[m3047]

All sourcefiles which define a info() method and also reference url_for():
