Dear Vaclav,
I wrote a first draft of a decorator: change_environ [0], that:
1. overwrite the environment variables,
2. execute the test and
3. restore the environment variables.
Probably I should modify the function with something like:
{{{
try:
func(*args, **kwargs)
finally:
# restore the environment variables
for k, v in envs.items():
oval = original_envs[k]
if oval == NOT_FOUND:
os.environ.pop(k)
else:
os.environ[k] = oval
}}}
Otherwise if the function raise an exception the current
implementation will not restore the environment variables back to
their original value.
But I think this kind of functionalities is general enough to be
somewhere in the gunittest code.
What do you think? Any idea?
All the best.
Pietro
