Greetings,
I'm using rspec with rcov for my applications and there is one issue
which I cannot solve nor can find any proper information regarding
it: specing what is in a rescue block in case of an exception.
I'm using Ruby on Rails and I usually make use of exceptions in my
controllers, like the following example:
def action
@foo = Foo.find(1)
@foo.update_attributes!(params[:foo])
redirect_to :back
rescue ActiveRecord::RecordInvalid => e
...exception handling code ...
rescue Exception => e
...exception handling code ...
else
...else block
ensure
...ensure block
end
I have a specs for this, like this one:
it "should retrieve a Foo instance, identified by ID and update it's
parameters" do
Foo.should_receive(:find).with("1").and_return(@foo)
@foo.should_receive(:update_attributes!).with
(valid_params).and_return(@foo)
get :action, :id => 1
response.should be_redirect
end
it "should retrieve a Foo instance, identified by ID and throw an
exception, because of bad parameters" do
Foo.should_receive(:find).with("1").and_return(@foo)
@foo.should_receive(:update_attributes!).with
(valid_params).and_return(@foo)
get :action, :id => 1
response.should raise_error
end
or
it "should retrieve a Foo instance, identified by ID and throw an
exception, because of bad parameters" do
Foo.should_receive(:find).with("1").and_return(@foo)
lambda { @foo.should_receive(:update_attributes!).with
(valid_params).and_return(@foo) }.should raise_error
get :action, :id => 1
end
... and ... that's it, the tests pass, becaue an Exception is raised,
but I don't know how to proceed with testing all the rescue, ensure
and else blocks. Since rcov reporting it as not being run, my
coverage is suffering and I really don't want to release code which
are only being partially tested.
So any pointers, help or links to some quick rundown regarding this
problem would be greatly appreciated.
Thanks a bunch and my best regards,
András
