[Twisted-Python] Help with Simple Trial unit test

Thanks a bunch Jean-Paul!!!
That was exactly my problem.
I replaced the reactor.run() line with "return d" and everything works perfectly.
So I guess the lesson here is that if a unit test creates a defer it needs to return that defer for everything to be hooked up properly and execute.

So
far
things
are
going
well,
except
that
I
can't
quite
figure
out
what
I'm
doing
wrong
in
this
simple
unit
test
I'm
writing.

the

of
a
simple
HTTP
GET
Based
communication
layer
between
legacy
systems.
As
such,
I
wanted
to
write
a
simple
unit
test
that
uses
the
twisted
client.getPage()
method
to
test
the
communication
process
(i.e.
simulates
a
legacy
system
requesting
data
from
the
server).

However,
I
find
that
I
have
to
add
a
reactor.run()
command
in
the
unit
test
for
the
test
to
actually
be
executed.
The
unfortunate
side
affect
of
this
is
that
you
then
have
to
ctrl+C
to
stop
the
reactor
after
the
test
runs.
If
I
don't
put
in
the
reactor.run()
command,
I
get
a
"REACTOR
UNCLEAN"
error
message
and
the
test
doesn't
appear
to
run
(at
least
the
callbacks
from
getPage()
never
happen).
What
happens
if
you
take
the
Deferred
created
in
the
test
method
and
return
it,
instead
of
calling
reactor.run()?
