TypeError: 'dict_keys' object does not support indexing

[rachna bafna]

I am getting following error for my tests which were running perfectly until some time back. Any clue what could cause this?

Appreciate your help on this.

Hi,

Does this happen always or not? We'd need some more context to understand what happens

It looks like the issue is that `dict.keys()` returns different types of objects in Python 2 and 3. It returns plain list in py2 and `dict_keys` object (which is pretty much an iterator) in py3.

So it looks like a relatively simple bug. I've created a fix for it: https://github.com/Blazemeter/taurus/pull/964

Thanks for reporting!
