Rspec issues

Rails
1

Hi,

i’ve started using rspec for this project (latest versions: rspec
1.1.9 and rspec-rails 1.1.9), and i stumbled upon the following
problems:

  • render_template:
    response.should render_template(‘new’)
    i get the following fail
    expected “new”, got “/Users/elise/Rails/myapp/app/views/user/profiles/
    new.html.erb”
    So it expects the full path. That can’t be right ?

  • should be: doesn’t give me the result i expect for two strings that
    are equal.
    assigns[‘page’].menu.should be(“home alone”)
    gives me
    expected “home alone”, got “home alone”

  • mocking (ok, i’m using mocha, so maybe it isn’t rspec): i make a
    mailer raise an error like this:
    DummyMailer.stubs(:deliver_invitation).raises(Exception)
    and in my code, surround this with begin … rescue, the exception is
    not caught !

Any tips ?

Thanks !

a) Are you sure deliver_invitation is being called?
b) Are you using just a default rescue clause? This will only rescue
StandardError’s and descendants of StandardError. Exception is not a
descendant of StandardError. I think Mocha raises a StandardError by
default, so if you change your stubbing as follows, a default rescue
clause
will work…

DummyMailer.stubs(:deliver_invitation).raises

If you are still seeing unexpected behaviour, come over to the Mocha
mailing
list [1] and we’ll see if we can help.

nope, it expects new and gets the full path instead.
what’s your render command?

Typical ruby thing. “should be” tests for the two
strings are an identical string object (one and the same thingy in
memory)
use:
assigns[‘page’].menu.should eql(“home alone”)

OK, thanks

b) makes sense, though it is surprising: I mean developer-defined
errors are usually Exceptions, and should be caught too, no ? I need
to pick up my ruby book again.

It’s a common developer mistake to derive new exception classes from
Exception, rather than StandardError. Such exception classes will not be
rescued by a default rescue clause.
