Hi Cleto,

I am going to ask to upstream about this but I think OutContains condition
has never been implemented. Instead of this, you can use FileContains
condition. In fact, FileContains condition has the task output as default
filename value.
Yeah, I noticed FileContains but I need something more flexible. I've written
an OutputContains plugin (attached) that filters and transforms stdout using
passed functions, and then verifies that the result contains a list of strings
in the given order. Here's an example invocation:
t.post += OutputContains(['foo::%s' % s for s in strings],
filter_func = lambda x: x.endswith(' started'),
map_func = lambda x: x.split()[8])
It could be generalised by testing the type of the strings argument, and do a
simple str in stdout check if the argument is a string, or an unordered
comparison if the argument is a set. Also, the filter and map args could
default to None, in case no filtering and transformation is needed.
Anyway, my 2c.
Cheers,
