I am trying to read in Rspec 3.1 a cookie received after get call.
I see it is returned but the last_response.cookies doesn't exist.
How can I read response's cookie?
it "doesn't signs in" do
get '/ui/pages/Home'
puts last_response.cookies
end
I know it has been a while, but facing exactly this same issue now, after some struggle, I've found an article here that shares an interesting approach. As I also couldn't find any native parsed method for this, that has worked fine for me.
Basically, place this piece of code below on your spec/spec_helper.rb:
def cookies_from_response(response=last_response)
Hash[response["Set-Cookie"].lines.map { |line|
cookie = Rack::Test::Cookie.new(line.chomp)
[cookie.name, cookie]
}]
end
and you could use this to see the parsed hash:
puts cookies_from_response
For a cookie's value check, you could then use something like:
# Given your cookie name is 'foo' and the content is 'bar'
expect(cookies['foo'].value).to eq 'bar'
Hopefully this becomes helpful to others facing similar issues.

Hi I want to know how can I write rspec for the following
def find_user(content)
user = User.find(content.to_i) ||
User.find(email: content) rescue
nil
end
I tried writing
It "user with user name" do
expect(User).to receive(:find).with(email: "test#a.com").and_return(user)
End
But I am gettig error saying
Argument Error
Block not Passed
Can someone please tell what am i missing
I may look first at your code here.
def find_user(content)
user = User.find(content.to_i) ||
User.find(email: content) rescue
nil
end
What is content? I looks like you're expecting either a user_id or an email address.
Doing this from the console:
irb(main):080:0> User.find("email#email.com".to_i)
=> ActiveRecord::RecordNotFound (Couldn't find User with 'id'=0)
So it seems as if having a generic find_user method may be contributing to some of the test writing confusion.
Many times, overly complex tests point to overly complex code.
Perhaps you need one method
find_user_by_email(email)
and another
find_user_by_id(id)
Also, refer to https://api.rubyonrails.org/v6.1.3.2/classes/ActiveRecord/FinderMethods.html#method-i-find_by
It will automatically return nil if nothing is found.
Start there, And then like the other commenters, then post your class, and the spec and we can go from there.
Probably a stupid question but I was following along this article and came across a bit of code I couldn't quite grasp. Here it is:
class CreateArticle
attr_reader :validate_article, :persist_article
def initialize(validate_article, persist_article)
#validate_article = validate_article
#persist_article = persist_article
end
def call(params)
result = validate_article.call(params)
if result.success?
persist_article.call(params)
end
end
end
More specifically, the problematic line is this:
if result.success?
Here's my problem with it: where did the success? method come from? It's not default in Ruby, and result is a local variable, so it should be nearby. But even if it's just omitted in the code sample, where would it have to be defined for that line to work? Everywhere I tried to define it just gave me an 'undefined method' error.
For example, I tried to define it both in the CreateArticle class and in the (only alluded to) ValidateArticle class, the obvious culprits, but no dice.
Update:
The reason I ask is not so much about what success? does as it is because I'm interested in using the pattern in my code. So, for example, my version of the success? method could be just checking whether a value got updated, or an item was inserted into an array. For example, let's say it's just this:
def success? # or self.success?
return true
end
Problem is, I can find no place where I can put this that works. I even created a module just for it and included it into the class, and still it doesn't work (it just returns 'undefined method'). So I'm still at a loss as to where I would have to define such a method so that it would work the way it looks like it should.
It's a method that comes with rails. It checks.for a server response with a 200 code. If it gets a 200 code it returns true else it returns false. Read the rails API docs about it... https://apidock.com/rails/v3.2.3/ActiveResource/Response/success%3F
Actually . success? is a built in ruby method. Check here. What it actually does is checking Stat and returns a boolean.
I did some more digging around the blog and from what I found I suspect that the code is probably making use of the dry-monads gem:
You can explicitly check the type by calling failure? or success? on a monadic value.
It's not explicit in the code excerpt but it's the only thing that makes sense.
I've searched for an answer to this but I just can't seem to figure out what's going wrong. I have an api client test that looks like the following:
module MyTests
describe '#update' do
# using a before(:all) block for setup
before(:all) do
#client1 = Client.new
#initial_payload_state = #client1.update.payload
end
context 'with a known starting payload' do
# The payload is some nasty nested json so I grab an existing one
# and then use a helper method to convert it to a full payload.
# Then I update the client with the new payload. I'm using before(:each)
# so I can get the client into this state for every test.
before(:each) do
#full_payload_state = helper_method(#initial_payload_state)
end
context 'alter_payload_1 works' do
# now that I have the payload in its full state I'd like to alter it to
# produce a certain output
before(:all) do
#new_payload_state = alter_payload_1(#full_payload_state)
end
# I now want to update the client with the altered payload and make sure
# it has the same data. The request and response bodies are formatted slightly
# differently in this case.
it 'works' do
#updated_payload_state = #client1.update(#new_payload_state)
expect(payloads_equal?(#full_payload_state, #new_payload_state).to eq true
end
end
context 'alter_payload_2 works' do
before(:all) do
#new_payload_state = alter_payload_2(#full_payload_state)
end
it 'works' do
#updated_payload_state = #client1.update(#new_payload_state)
expect(payloads_equal?(#full_payload_state, #new_payload_state).to eq true
end
end
In reality, my before block for setup is much longer, so I think it makes sense to keep it that way. I tried to use a before(:each) block so I could have the same known state to start each of the alter_payload contexts. The problem is that with this setup, I get a no method error for this line:
#new_payload_state = alter_payload_1(#full_payload_state)
suggesting that #full_payload_state is nil. I'm certain I've got something wrong with respect to scope, but I'm not sure why or how to fix it. Any help greatly appreciated!
Looks like a scope issue with before(:all).
In general, it's wise to stop using before(:all) because it entangles your tests.
Replace your before(:all) lines with before(:each), and this will make each of your tests independent of the others. This will likely help you find your glitch.
I'm using VCR gem to record http interactions and replay them in future. I want to filter-out my actual password value in the uri request. Here's sample of what the uri looks like:
http://services.somesite.com/Services.asmx/Cabins
Username=long&Password=john&StartDate=03%2F22%2F2012&EndDate=03%2F29%2F2012
Though an explanation is provided here, I'm still not sure how to do it after a few attempts myself:
https://www.relishapp.com/myronmarston/vcr/v/2-0-0/docs/configuration/filter-sensitive-data
Any help would be appreciated.
VCR.configure do |c|
c.filter_sensitive_data("<SOMESITE_PASSWORD>") do
ENV['SOMESITE_PASSWORD']
# or $credentials['somesite']['password'] or whatever
end
end
Essentially, you give VCR a bit of placeholder text, and then the block needs to return the real password, reading it from whatever the canonical password "repository" is.
Note that the real password is only needed the first time, when the request is recorded; on subsequent runs, it can be a fake password (as long as it's the same fake password used by the code making the request).
for rails 4+, if you are using secrets.yml you might want to do
VCR.configure do |config|
Rails.application.secrets.each do |k,v|
config.filter_sensitive_data("ENV[#{k}]") { v }
end
end
now you're sure not to forget any
This might be a similar problem to my earlier two questions - see here and here but I'm trying to use the _detail command to automatically click the link so I can scrape the details page for each individual event.
The code I'm using is:
require 'rubygems'
require 'scrubyt'
nuffield_data = Scrubyt::Extractor.define do
fetch 'http://www.nuffieldtheatre.co.uk/cn/events/event_listings.php'
event do
title 'The Coast of Mayo'
link_url
event_detail do
dates "1-4 October"
times "7:30pm"
end
end
next_page "Next Page", :limit => 20
end
nuffield_data.to_xml.write($stdout,1)
Is there any way to print out the URL that using the event_detail is trying to access? The error doesn't seem to give me the URL that gave the 404.
Update: I think the link may be a relative link - could this be causing problems? Any ideas how to deal with that?
I had the same issue with relative links and fixed it like this... you have to set the :resolve param to the correct base url
event do
title 'The Coast of Mayo'
link_url
event_detail :resolve => 'http://www.nuffieldtheatre.co.uk/cn/events' do
dates "1-4 October"
times "7:30pm"
end
end
sudo gem install ruby-debug
This will give you access to a nice ruby debugger, start the debugger by altering your script:
require 'rubygems'
require 'ruby-debug'
Debugger.start
Debugger.settings[:autoeval] = true if Debugger.respond_to?(:settings)
require 'scrubyt'
nuffield_data = Scrubyt::Extractor.define do
fetch 'http://www.nuffieldtheatre.co.uk/cn/events/event_listings.php'
event do
title 'The Coast of Mayo'
link_url
event_detail do
dates "1-4 October"
times "7:30pm"
end
end
next_page "Next Page", :limit => 2
end
nuffield_data.to_xml.write($stdout,1)
Then find out where scrubyt is throwing an exception - in this case:
/Library/Ruby/Gems/1.8/gems/scrubyt-0.3.4/lib/scrubyt/core/navigation/fetch_action.rb:52:in `fetch'
Find the scrubyt gem on your system, and add a rescue clause to the method in question so that the end of the method looks like this:
if ##current_doc_protocol == 'file'
##hpricot_doc = Hpricot(PreFilterDocument.br_to_newline(open(##current_doc_url).read))
else
##hpricot_doc = Hpricot(PreFilterDocument.br_to_newline(##mechanize_doc.body))
store_host_name(self.get_current_doc_url) # in case we're on a new host
end
rescue
debugger
self # the self is here because debugger doesn't like being at the end of a method
end
Now run the script again and you should be dropped into a debugger when the exception is raised. Just try typing this a the debug prompt to see what the offending URL is:
##current_doc_url
You can also add a debugger statement anywhere in that method if you want to check what is going on - for example you may want to add one between line 51 and 52 of this method to check how the url that is being called changes and why.
This is basically how I figured out the answer to your previous questions.
Good luck.
Sorry I have no idea why this would be nil - every time I have run this it returns a url - the method self.fetch requires a URL which you should be able to access as the local variable doc_url. If this returns nil also may you should post the code where you have included the debugger call.
I've tried to access doc_url but that seems to also return nil. When I have access to my server (later in the day) I'll post the code with the debugging bit in it.
