[Fab-user] Isolating env for unittests?

[Chris Spencer]

What's the best way to save and restore env?

I'm trying to unittest some custom Fabric tasks, and I'm having a real
problem not-polluting the global env variable. I've tried things like:

tmp = env.copy()
...run test
env.clear()
env.update(tmp)

but I still get weird errors caused by left-over env keys from other tests.

Hi Chris,

I think the cleanest way is to use the context manager settings()
<http://docs.fabfile.org/en/1.13/usage/env.html#the-settings-context-manager>

From the docs:

from fabric.api import settings, run
def exists(path):
with settings(warn_only=True):
return run('test -e %s' % path)

Regards

Globals are always a pain,

I use a decorator:

and then:
