[py-dev] py.test problem

[Simon Burton]

I have hit this problem several times, when an assertion fails using py.test i get

AttributeError:   << 'frame' object has no attribute 'eval'

with no stack trace of where in py.test this occured. (only the stack trace of my test code).

Any ideas ?

It looks like it has something to do with the magic that prints out the values of expressions
in the assertion.

I just did svn up on my py.test, it did not help.

Simon.
