Testing errors

Rails
1

I have this method in user_controller_test.rb file
def test_auth_bob
#check we can login
post :login, :user=> { :login => “bob”, :password => “test” }
assert_session_has :user
assert_equal @bob, session[:user]
assert_response :redirect
assert_redirected_to :action=>‘welcome’
end

I get this Error:
test_auth_bob(UserControllerTest):
NoMethodError: undefined method assert_session_has' for #<UserControllerTest:0x 28772e0> C:/Ruby19/lib/ruby/gems/1.9.1/gems/actionpack-2.3.5/lib/action_controller/te st_process.rb:511:inmethod_missing’

I get this Error:
test_auth_bob(UserControllerTest):
NoMethodError: undefined method `assert_session_has’ for
#<UserControllerTest:0x
28772e0>

A quick google search shows assert_session_has as being deprecated in
2006, so presumably it is now gone. You will have to do it a
different way.

Thank you. Yes ‘assert_session_has’ and ‘assert_session_has_no’ has
been replaced by ‘assert_nil session’

Now I am getting another error:

Error:
test_bad_signup(UserControllerTest):

The ‘signup’ method is defined as:
def signup
@user = User.new(@params[:user])
if request.post?
if @user.save
session[:user] = User.authenticate(@user.login, @user.password)
flash[:message] = “Signup successful”
redirect_to :action => “welcome”
else
flash[:warning] = “Signup unsuccessful”
end
end
end

The tester is calling ‘signup’ as
def test_signup
#check we can signup and then login
post :signup, :user => { :login => “newbob”, :password =>
“newpassword”, :password_confirmation => “newpassword”, :email =>
“[email protected]” }
assert_response :redirect
assert_not_nil session[:user]
assert_session_has :user
assert_redirected_to :action=>‘welcome’
end

Please tell me, what I am doing wrong?

The error occurred while evaluating nil.[]
C:/VR/RailsPrograms/health/app/controllers/user_controller.rb:5:in
`signup’

That means the error is on line 5 of user_controller (I would have
expected it to be users_controller by the way, following the rails
conventions). Looking at the error it seems you have
some_variable[…] where some_variable is nil. You have not told us
which is line 5 but if you have a look there you should see which
variable it is and then be able to work out why it is nil.

If all else fails have a look at the Rails Guide on debugging and use
one of the techniques there to work out what is going on. I like to
use ruby-debug to break in to the failing area when the test runs and
inspect the variables. In fact even if you can see the problem
without debugging have a look at the guide for future reference.

I am sorry I posted wrong tester calling method. The correct calling
method for testing is:
def test_bad_signup
#check we can’t signup without all required fields
post :signup, :user => { :login => “newbob”, :password =>
“newpassword”, :password_confirmation => “wrong” , :email =>
“[email protected]”}
assert_response :success
assert_invalid_column_on_record “user”, “password”
assert_template “user/signup”
assert_nil session[:user]

post :signup, :user => { :login => "yo", :password => "newpassword",

:password_confirmation => “newpassword” , :email => “[email protected]”}
assert_response :success
assert_invalid_column_on_record “user”, “login”
assert_template “user/signup”
assert_nil session[:user]

post :signup, :user => { :login => "yo", :password => "newpassword",

:password_confirmation => “wrong” , :email => “[email protected]”}
assert_response :success
assert_invalid_column_on_record “user”, [“login”, “password”]
assert_template “user/signup”
assert_nil session[:user]
end

I am just instantiating User class object. How is this nil - I do not
understand Rail syntax enough to find out what is going on?

Read the error message again and also what I said, the error is that
it is trying to evaluate something[…] where something is nil. It is
not user that is nil but @params.

Did you try my suggestion of debugging if you could not work it out?

So why is @params nil? Probably because it should be params not
@params.

I cannot find out on Google about error on ‘find_record_in_template’.
I don’t know how to fix this - is this also deprecated or is it my
syntax error?

http://dev.rubyonrails.org/ticket/7385 suggests this has also gone,
you will have to find another way.

Also you mentioned about debugging - is there a simple document that
discribes this?

I think I suggested the Rails Guide on debugging (google rails
guides). If you have not already seen them the Getting Started guide
and ActiveRecord Associations are compulsory reading.

I got another error on the line
assert_invalid_column_on_record “user”, “login”

So I googled and found that it is deprecated and hence suggested using:
assert(find_record_in_template(“user”).errors.invalid?(:password))

When I use this I get error :
test_bad_signup(UserControllerTest):
NoMethodError: undefined method find_record_in_template' for #<UserControllerTe st:0x29fbe40> C:/Ruby19/lib/ruby/gems/1.9.1/gems/actionpack-2.3.5/lib/action_controller/te st_process.rb:511:in method_missing’

I used
u = User.new
assert !u.valid?
assert u.errors.on(:password)
That worked.

Do I have to use Mongrel Server to debug? Can I use IIS? Are there
advantages/diadvantages.
Also is there a light weight open source code/editor for Ruby. Right now
I am using Notepad++.

Thank your for your patience and guidance. I am learning a lot. Coming
from .NET world it is kind of hard to get the syntax. I read ruby guide.
it is difficult in one reading. May have to go back and forth between
writing code and reading.

Also when I use this test code:
post :login, :user=> { :login => “bob”, :password => “test” }
assert_nil session[:user] # assert_session_has & _has_no have been
deprecated
assert_equal @bob, session[:user]

I get this failure - what does it mean?

  1. Failure:
    test_auth_bob(UserControllerTest)

I doubt if you can use IIS for debugging. I don’t know about it. If
you are serious about Rails I would suggest having a look at Ubuntu (a
flavour of Linux). Linux manages Rails much better than windows. You
can set your PC up to dual boot windows and Ubuntu so you can still
keep windows also. I did this and now very rarely use windows. It is
great. Have a look at the free downloadable guide at
Main page - Ubuntu Pocket Guide and Reference if you are
interested. Of course you would have to put your rails stuff on hold
for a while in order to get the hang of Ubuntu.

Also is there a light weight open source code/editor for Ruby. Right now
I am using Notepad++

I use jEdit, which is open source and runs on win and linux (and mac).

Thank your for your patience and guidance. I am learning a lot. Coming
from .NET world it is kind of hard to get the syntax. I read ruby guide.
it is difficult in one reading. May have to go back and forth between
writing code and reading.

I would also suggest a new tutorial which is not yet complete (but
goes far enough to get you going) at http://www.railstutorial.org/

[test/functional/user_controller_test.rb:25]:
Expected #<User id: 1000001, login: “bob”, hashed_password:

last_nam
e: nil, phone_num: nil, user_role: “patient”> to be nil.

Again if you look carefully at what appears at first to be random words
it says
At user_controller_test.rb line 25, expected … to be nil.
On that line you have said
assert_nil session[:user]
so it is saying that it expected it to be nil, but it is not, and is
showing you what it is.

I prefer a dual boot personally but it is a matter of preference.
Many install ubuntu then run windows in VMWare or VirtualBox.

Before you install rails, google for install rails ubuntu as you want

you get there if you want it.

Now all assert save fails. I hope this is the last error that I will

Why is ssert save failing - it does not give me any errors?
Perhaps you have a validation failing. If you put
assert u.valid?, u.errors.full_messages
before the save valid? will fail and display the validation errors.
Or you could probably just put the messages on the assert u.save. I
like to do the valid test explicitly though.

Thanks, I will try this.

assert_nil session[:user]
so it is saying that it expected it to be nil, but it is not, and is

I got this error figured out.

Now all assert save fails. I hope this is the last error that I will
have to overcome.

Failure:
test_send_new_password(UserTest) [test/unit/user_test.rb:145]:
Failed assertion, no message given.

user_test_controller.rb code line 145 refers to assert u.save as below:

def test_send_new_password
u = User.new :login => “bob”,
:password => “test”,
:email => “[email protected]”,
:phone_num => “(212)111-1111”,
:first_name=> “robert”,
:last_name => “baker”,
:user_role => “Patient”

assert u.save

end

The code being called in user.rb:
def send_new_password
new_pass = User.random_string(10)
self.password = self.password_confirmation = new_pass
self.save
Notifications.deliver_forgot_password(self.email, self.login,
new_pass)
end

The column names in the database are all correct as below:
id
login
hashed_password
email
salt
created_at
updated-at
first_name
last_name
phone_num
user_role

Why is ssert save failing - it does not give me any errors?

How do I send personal email to you from the forum. I tried to search

please tell me how I can send message to you. I defnitely want to use

reason I am switching from .NET to Ruby so that the app can run on
multiple OS.

I don’t know the pros and cons of the two virtual machine layouts, as
I said I prefer a dual boot. The ubuntu install can split your disk
into two partitions and install itself on one, leaving windows in the
other after squashing it down to fit. Then at boot time you choose
which you want. We are getting a bit OT here, if you are interested
in ubuntu I would suggest subscribing to the ubuntu users list
https://lists.ubuntu.com/mailman/listinfo/ubuntu-users

please tell me how I can send message to you. I defnitely want to use

As I use the list as a mailing list you should be able to see my email
address, but perhaps you cannot on the forum web interface. I find it
works much better as a mailing list than the forum. But again that is
a matter of taste. I can’t see yours so I presume you are using it as
a forum. Mine is clanlaw at googlemail dot com
