I am following a tutorial and have been getting some errors, I believe some of the language is outdated with Rspec and have messed around alot to try and fix this but have not been able to.
The error i get is
NoMethodError:
undefined method `should_recieve' for #<Panda:0x007f9cd45c6458>
# ./spec/zookeeper_spec.rb:9:in `block (2 levels) in <top (required)>'
The code in question is
describe Zookeeper do
it "should be able to feed the bamboo to the pandas" do
panda = Panda.new
panda.should_recieve(:eat).with(:bamboo)
Zookeeper.new.feed(food: :bamboo, to: panda)
end
I have realised that should_recieve should actually be should_receive and this has resolved the problem. I then replaced should_receive with and expectation and to receive
describe Zookeeper do
it "should be able to feed the bamboo to the pandas" do
panda = Panda.new
expect(panda).to receive(:eat).with(:bamboo)
Zookeeper.new.feed(food: :bamboo, to: panda)
end

When running through the rspec course in codeschool I keep running into the same problem. I will set up as requested and after creating zombie_spec.rb and running rspec I get the proper output listed below:
Justins-MacBook-Pro:rubyproject Justin$ rspec spec/lib/zombie_spec.rb
Run options: include {:focus=>true}
All examples were filtered out; ignoring {:focus=>true}

A Zombie is named Ash

As I continue on with the first video and create the class Zombie as mentioned I receive this error when running rspec again:
Justins-MacBook-Pro:rubyproject Justin$ rspec spec/lib/zombie_spec.rb

After this I removed everything and uninstalled and reinstalled rspec. Retried it again and returned the same results.
Any clue what is going on?
Thank you in advance for your help!
require_relative will load the file from the same directory as the rspec file
I had pretty much the same issue, though mine never worked even once at first. Updating the zombie_spec.rb file to show the full path of my zombie.rb file seemed to get it working properly.
Eg:require "/home/me/ruby/spec/lib/zombie"
I use this and it worked
require_relative "zombie.rb"
Well if this still a problem I got into the same issue so I created a folder under spec/lib where I put all the codes and another spec/test where goes all the tests then it worked.
and I also added require_relative here is the code snippet
zombie_spec.rb
require 'spec_helper'
require_relative '../lib/zombie'
describe Zombie do
it "has a name called'Jack'" do
zb = Zombie.new
zb.name.should == "Jack"
end
it "has no brains" do
zb = Zombie.new
zb.should be_intelligent == false
end
end
zombie.rb
class Zombie
attr_accessor :name
def initialize
#name = "Jack"
end
def intelligent?
false
end
end
I am trying to run given scenarios as many times per each account type. I found out in other thread that "around hooks" could be the best option to do it the DRY way.
Below is my code:
require 'watir-webdriver'
require 'page-object/page_factory'
require 'page_navigation'
require 'data_magic'
require_relative 'pages/login_page'
Before do
beforeCodeBlock
...
end
Around('#hooks_test') do|scenario, block|
DataMagic.load('default.yml')
account_type = {"listener" => DataMagic.yml["listener_data"],
"free" => DataMagic.yml["free_data"],
"premium" => DataMagic.yml["premium_data"]}
account_type .each {|key, value|
puts "Running scenario: #{scenario.name} as #{key} user"
visit_page(LoginPage)
on_page(LoginPage).sign_in(value["username"],value["password"]) #Login as
block.call
}
end
After do
afterCodeBlock
...
end
So when I run the feature file I get the following output and subsequent error:
Running scenario: Hooks test as listener user
undefined method `visit_page' for nil:NilClass (NoMethodError)
/myProject/features/support/hooks.rb:38:in `block (2 levels) in <top (required)>'
/myProject/features/support/hooks.rb:35:in `each'
/myProject/features/support/hooks.rb:35:in `Around'
Everything seems to be working as expected until the execution deals with the visit_page method that belongs to PageObject gem.
There are possibly two problems I see here.
First of all you are getting the error because you did not register the PageObject::PageFactory module with World. Add this line after the requires:
World(PageObject::PageFactory)
Second, you are using an Around block and calling the same Scenario multiple times. From what I am seeing, you are doing this so that it will exercise the same behavior with different logged in users. If the behavior is exactly the same, what are you accomplishing by running it three times?
I'm using RSpec (latest Version, 2.12.2) to test a small Ruby class I'm working on. My problem is that when an RSpec test fails, the test output seems incredibly verbose, and shows a huge list of error messages, almost what seems to be a full backtrace. This means I have to scroll up to see the actual error message and the top of the trace.
I believe by default RSpec is supposed to do this but it doesn't seem to be doing it for me. For example, if I run rspec spec/my_spec.rb:132 (just run one test that's on L132), I get this output:
Failure/Error: #f.has_changed?("test").should be_true
expected: true value
got: false

Which, as you can see, is absolutely massive. I've not got any RSpec config files around that could be altering the configuration passed to RSpec.
Has anyone seen this before? I've tried Googling but searches have been fruitless.
Edit: I then set up config to make sure it was applying the default backtrace cleaning:
RSpec.configure do |config|
# RSpec automatically cleans stuff out of backtraces;
# sometimes this is annoying when trying to debug something e.g. a gem
config.backtrace_clean_patterns = [
/\/lib\d*\/ruby\//,
/bin\//,
/gems/,
/spec\/spec_helper\.rb/,
/lib\/rspec\/(core|expectations|matchers|mocks)/
]
end
But this doesn't make a difference. Looking at the output, it should be having most of it filtered out but it seems like the configuration isn't being applied?
Edit again:
In my config, I can even run cleaned_from_backtrace?(line) to see if a line should be cleaned. This returns true:
config.cleaned_from_backtrace?("/Users/JackFranklin/.rbenv/versions/1.9.3-p194/lib/ruby/gems/1.9.1/gems/rspec-expectations-2.12.1/lib/rspec/expectations/fail_with.rb:33:in `fail_with'")
But the actual output in the terminal remains the same!
Edit 3:
I am running RSpec with the command rspec, and nothing more. The project's .rspec file contains:
--color
--format progress
And there is no ~/.rspec file either that could be applying settings.
So after a bit more chatting with the RSpec folk on Github, I managed to hunt down the problem.
The problem was that by default, RSpec removes lines from the backtrace that match the Regex /gems/. I had my project within a folder with gems in the name: ~/Dropbox/rubygems/myproject, so every line of the backtrace was being removed, and when that happens, RSpec sensibly shows you the entire backtrace.
That explains the behaviour I was seeing.
It's always something silly like that. I hope if anyone else does this, perhaps this answer will save them some time.
Looks like you're running RSpec with -b, for a full backtrace. Normally, RSpec won't show its own internal backtrace like that, even when your test fails badly (i.e. throws an exception rather than just failing an assertion). If you're not explicitly running it with -b or --backtrace, check and make sure that you don't have that set in a .rspec config file, or that your IDE or whatever isn't passing it.
As Jim said, there's a -b or --backtrace option that will enable the full backtrace. Bear in mind that it's not just the .rspec file that could be triggering it; there's also ~/.rspec (for a developer's preferred options).
The other thing to bear in mind is that a formatter can spit out whatever portion of the backtrace that it wants. The formatters expose a simple way for any 3rd-party formatter to respect the backtrace-filtering configuration, but it you're using a 3rd-party formatter there is no guarantee it is using that properly. Are you using one of the built-in rspec formatters?
Finally, if it's not one of those things, I'm out of ideas. I'd have to have an example to play with to answer your question. Can you come up with a reproducible example (in a gist, hopefully)? I try to hang out in the rspec channel of irc.freenode.net regularly, so maybe you can catch me there and we can do some troubleshooting that way.
From version 3.4.0 / 2015-11-11 it is possible to filter backtrace by option:
RSpec.configure do |config|
config.filter_rails_from_backtrace!
end
I have some Ruby code I need to execute in the Redmine Ruby app in order to enable a module in all projects at once.
Surprisingly, ruby does access the Projects, but raises a NoMethodError when accessing a few particular methods inside each of the "Project" objects.
Here is the code:
Project.find(:all).each do |project|
print "Enabling modules for project '#{project.identifier}' ... "
puts project.methods.sort # this does print "enabled_module_names"
puts project.enabled_module_names
end
This fails with:
hostname:/srv/apps/redmine# script/runner vendor/plugins/customplugin/lib/enable_modules.rb
/var/lib/gems/1.8/gems/activerecord-2.3.5/lib/active_record/attribute_methods.rb:260:in `method_missing': undefined method `enabled_module_names' for #<Project:0x7f28985c1cb0> (NoMethodError)

from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require'
from script/runner:3
I have scratched my head a lot, but I can't grasp why would the code find the "Project" symbol but not the methods within, especially as "project.methods" does indeed list "enabled_module_names".
Any help most welcome.
Are you sure that enable_module_names is an instance method?
Is it within Project.instance_methods?
Edit (summary of the comments below):
In earlier versions, you have to use following:
enabled_module_names = project.enabled_modules.collect(&:name)
The getter is present in later versions only (see rev.4460 for details of this change)
I'm running into something weird here.
I have an "authenticator" that relies on ND5 to hash a certain string we match as password. The problem when I run my tests is this:
NoMethodError: undefined method `md5' for #<CASServer::Authenticators::Billing:0x007fd8e6c906a0>
./models/authenticators/billing.rb:63:in `validate'
./routes/login.rb:166:in `block (2 levels) in <class:Server>'
./routes/login.rb:158:in `each'
./routes/login.rb:158:in `block in <class:Server>'
(eval):2:in `click_button'
./features/step_definitions/when_steps.rb:32:in `/^I enter "(.*)" as username and the generated username password and log in$/'
./features/rubycas.login.feature:14:in `When I enter "username" as username and the generated username password and log in'
So basically he does not recognize the MD5 as part of the Digest library.
This problem occurs when running the tests in the IDE, as well as in the IRB console:
1.9.3-p125 :001 > require "digest/md5" and Digest::MD5("test")
NoMethodError: undefined method `MD5' for Digest:Module
However, when I run the following:
[root#DCUDEV01 /home/morn/rubycas/current]# ruby
require "digest/md5" and Digest::MD5("test")
I receive no errors, dumps or exceptions. Ruby just accepts it.
What am I missing in order to get this MD5 stuff working?
Digest::MD5 is not a method but a module. Try
Digest::MD5.digest("test")
I found it confusing, it doesn't seem like .digest is correct. I can't say it is wrong either...
Commenter #reconbot got it right, IMO, but I saw the comment only after coming back to improve this QA, I think a comment isn't visible enough.
http://ruby-doc.org/stdlib-2.4.0/libdoc/digest/rdoc/Digest/MD5.html
Below is an example usage for md5 hasing for gibbon usage, the mailchimp gem.
md5_hashed_email_address = Digest::MD5.hexdigest("john.doe#example.com")
