Hi all,
With some time spent last Tue on the nyc.rb hackfest, I have a second
video
today of my endeavours with RSpec and recordings. It shows a handful
of When&Then steps, with the accompanying GTK2 GUI executing these
steps.
One nasty thing about Gtk (and virtually all other toolkits) is that
they think they are all-important. You have to call Gtk.main, which only
returns when the GUI is dead. Of course, my test is all-important here.
The consequence is that I can not rely on the default exit hooks of
rspec.
we get:
Thread.new {
run_tests
exit
}
Gtk::main
where I need to register my own story runner, define the tests and run
it:
def run_tests
narrator = Narrator.new({}, “here”)
sr = Spec::Story::Runner::ScenarioRunner.new
story_r = Spec::Story::Runner::StoryRunner.new(sr)
story_r.add_listener narrator
Spec::Story::World.add_listener narrator
story_r.instance_eval {
define_tests
}
story_r.run_stories
end
where Narrator is my class with step_upcoming, step_succeeded,
method_missing
and then a few; where define_tests is a method that contains
Story() { Scenario() { … } }
Note that I need to register my narrator twice to get all methods
called (bug? should I file a ticket?).
If I use
Spec::Story::Runner.register_listener narrator
instead, the World / steps are executed, but the runner /
scenario_started
callbacks are not. Unexpectedly, I get a free PlainTextFormatter (wtf?)
I have no qualms with a good formatter like PlainText, that frees me
from redoing the work. But, when I try to register one by hand, in the
way that seems to be done in rspec/lib/spec/story/runner.rb :
Spec::Story::Runner.register_listener
Spec:
:Formatter::Story::PlainTextFormatter.new({}, STDOUT)
I get
rspec/lib/spec/runner/formatter/base_text_formatter.rb:97:in
colour?': undefined method colour’ for {:colour=>false}:Hash
(NoMethodError)
which isn’t neither too weird, nor too comforting. Any hints for a
shortcut,
before I fake option parsing (or decide I want the arguments from my own
command-line,
regardless)?
And then of course, what you’ve been reading/waiting for:
http://chmeee.dyndns.org/ruby/List%20tasks%20in%20a%20Gtk%20Tree.wmv
(only 5.5 MB, including snippets of the code that generated it).
mencoder does not really play nice and synchronization of audio+video
has been tweaked by hand (that’s not necessary when playing directly
from running the story, of course; look at the clock in the bottom
right and you’ll understand), and it is still a mess near the end.
So I’m still looking for alternative tools to do speech synthesis (sox
refuses to play some of the shorter espeak wavfiles, I bet sox is right
and espeak is wrong) and encoding video.
Bye,
Kero.
