When I run rails c, I can call the following class and the method works:
test = SlackService::BoardGameNotifier
test.create_alert("test")
>>method works
I'm trying to set this up in rspec like this:
require 'spec_helper'
require 'slack-notifier'
RSpec.describe SlackService::BoardGameNotifier do
describe '#notify' do
#notifier = SlackService::BoardGameNotifier
it 'pings Slack' do
error = nil
message = "test"
expect(notifier).to receive(:ping).with(message)
notifier.send_message()
end
end
end
But I keep getting the error:
NameError:
uninitialized constant SlackService
Does this have to do with how I set up the module?
My current setup:
slack_service/board_game_notifier.rb
module SlackService
class BoardGameNotifier < BaseNotifier
WEBHOOK_URL = Rails.configuration.x.slack.url
DEFAULT_OPTIONS = {
channel: "board-games-channel",
text: "board games alert",
username: "bot",
}
def create_alert(message)
message #testing
end
end
end
slack_service/base_notifier.rb
module SlackService
class BaseNotifier
include Singleton
def initialize
webhook_url = self.class::WEBHOOK_URL
options = self.class::DEFAULT_OPTIONS
#notifier = Slack::Notifier.new(webhook_url, options)
end
def self.send_message
message = instance.create_alert("test")
instance.notify(message)
end
def notify(message)
#notifier.post blocks: message
end
end
end
Add this to your spec_helper.rb
# spec_helper.rb
ENV["RAILS_ENV"] ||= "test"
require File.expand_path("../config/environment", __dir__)
When running RSpec, Rails doesn't automatically boot up, and therefore doesn't automatically load all the libraries.
Also, I'd suggest creating a .rspec in your app's root folder with the following lines so that spec_helper is automatically loaded for all your RSpec tests:
# .rspec
--format documentation
--color
--require spec_helper
I would use the described_class from Rspec
require 'spec_helper'
require 'slack-notifier'
RSpec.describe ::SlackService::BoardGameNotifier do
describe '#notify' do
it 'pings Slack' do
error = nil
message = "test"
expect(described_class).to receive(:ping).with(message)
notifier.send_message()
end
end
end
I have a gemfile with the following:
# frozen_string_literal: true
source "https://rubygems.org"
gem 'cucumber'
gem 'minitest', '~> 5.10', '>= 5.10.3'
gem 'minitest-focus'
gem 'minitest-reporters', '~> 1.1.9'
gem 'rspec'
...
A Cucumber .env file with this to load and require the gems:
require 'bundler'
Bundler.require
And a Ruby file with the following:
require 'minitest/autorun'
require_relative './../../../../RubyProjects/mksta-common/common'
class VerifyApi < MiniTest::Test
include Common
def initialize(has_authorization)
#has_authorization = has_authorization
end
def test_id_correct
assert_equal(20, 20)
end
end
I am receiving this error when attempting to do that assert:
undefined method `+' for nil:NilClass
In Assertions.rb:
def assert_equal exp, act, msg = nil
msg = message(msg, E) { diff exp, act }
result = assert exp == act, msg
if exp.nil? then
if Minitest::VERSION =~ /^6/ then
refute_nil exp, "Use assert_nil if expecting nil."
else
where = Minitest.filter_backtrace(caller).first
where = where.split(/:in /, 2).first # clean up noise
warn "DEPRECATED: Use assert_nil if expecting nil from #{where}. This will fail in Minitest 6."
end
end
result
end
def assert test, msg = nil
self.assertions += 1
unless test then
msg ||= "Expected #{mu_pp test} to be truthy."
msg = msg.call if Proc === msg
raise Minitest::Assertion, msg
end
true
end
Error occurs at the line: "self.assertions += 1" so i am not sure where "assertions" is not being set..
I am wondering if my require process is incorrect, or if i am missing a requirement. Or perhaps Cucumber / Rspec is getting in the way? Any help would be appreciated.
Well, the problem is when you initialize VerifyApi, you did not initialize MiniTest::Test. So the self.assertions is nil.
To solve this problem, you just need to add one more line in the initialize function
super(name)
Of course, you need add one parameter in the function.
Whatever that I try to do is generating the error message below:
/home/diogodalla/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/activesupport-5.1.4/lib/active_support/dependencies.rb:292:in `require': Could not load 'active_record/connection_adapters/sqlite3_adapter'. Make sure that the adapter in config/database.yml is valid. If you use an adapter other than 'mysql2', 'postgresql' or 'sqlite3' add the necessary adapter gem to the Gemfile. (LoadError)
I'm using PG on my gemFile, I don't know why it keep looking for sqlite3.

# In an autoloaded user.rb like this
#
# autoload :Foo, 'foo'
#
# class User < ActiveRecord::Base
# end
#
# we correctly register "Foo" as being autoloaded. But if the app does
# not use the "Foo" constant we need to be careful not to trigger
# loading "foo.rb" ourselves. While #const_defined? and #const_get? do
# require the file, #autoload? and #remove_const don't.
#
# We are going to remove the constant nonetheless ---which exists as
# far as Ruby is concerned--- because if the user removes the macro
# call from a class or module that were not autoloaded, as in the
# example above with Object, accessing to that constant must err.
unless parent.autoload?(to_remove)
begin
constantized = parent.const_get(to_remove, false)
rescue NameError
# The constant is no longer reachable, just skip it.
return
else
constantized.before_remove_const if constantized.respond_to?(:before_remove_const)
end
end
begin
parent.instance_eval { remove_const to_remove }
rescue NameError
# The constant is no longer reachable, just skip it.
end

ActiveSupport::Dependencies.hook!
Any tips abut it?
thank you all.
Where do you install libraries ? Try following procedure before running Rails, please.
Remove local libraries and re-install
$ rm -rf ./vendor/bundle
$ bundle install --path ./vendor/bundle
$ bundle exec rails server
When we are trying to execute the below code we are not able access data newAccount and also not able to search date in active records in it method
Code Extract:
describe "search with name" do
before :each do
newAccount = Account.new
newAccount.firstname = "涯噘暮"
newAccount.id = "405"
newAccount.save
data = Account.execute_sql(['Select * from account where sfid= ? ','1'])
puts "Debug : #{data.to_json}"
newAccount = Account.new
newAccount.firstname = "涯 噘 暮"
newAccount.id = "2"
newAccount.save
end
it "should return direct matches during search" do
puts "#{newAccount}"
puts "#{Account.find_by_id(405)}"
end
end
Details of gem lib: These are the libraries that we are using for testing.
gem 'rspec-rails', '2.5.0'
gem 'faker'
gem 'capybara'
gem 'guard-rspec'
gem 'launchy'
gem 'simplecov', :require => false
gem 'resque_spec'
You have 2 errors here:
Variable names in Ruby are case-sensitive, so newaccount is different from newAccount, use one of them, preferably Ruby style guide recommends snake case (new_account)
newAccount in before(:each) is not visible in any it block. Consider them as different methods of one object, this way each method has its own local variables, that are invisible for other variables. The solution is to use instance variables, that can be shared inside different methods of one object.
This code should work:
describe "search with name" do
before :each do
#newAccount = Account.new
#newAccount.firstname = "涯噘暮"
#newAccount.id = "405"
#newAccount.save
data = Account.execute_sql(['Select * from account where sfid= ? ','1'])
puts "Debug : #{data.to_json}"
#newAccount = Account.new
#newAccount.firstname = "涯 噘 暮"
#newAccount.id = "2"
#newAccount.save
end
it "should return direct matches during search" do
puts "#{#newAccount}"
puts "#{Account.find_by_id(405)}"
end
end
You need to check if your account is really saved. You can
Add p #newAccount.errors.full_messages after #newAccount.save to see if there are any validation errors preventing your model to be saved.
Use #newAccount.save! instead of #newAccount.save (note the ! character). This will throw an exception if your save was unsuccessful.

How do I use firebase across methods and not locally as shown in the examples? Ex: #firebase, See the paste at --
http://bpaste.net/show/501b6a67c8d4
or --
require 'sinatra'
require 'firebase'
require 'bundler'
Bundler.require
# Configure database
configure do
#base_uri = 'https://veriyo.firebaseio.com/'
#firebase = Firebase::Client.new(#base_uri)
end
# Display homepage
get '/' do
erb :index
end
post '/search' do
#username = params["username"]
redirect to("/user/#{#username}")
end
get '/user/:username' do
response = #firebase.push("todos", { :name => #username })
'hello'
end
The #firebase variable's attributes aren't accessible there -- #<NoMethodError: undefined methodpush' for nil:NilClass>`
Set them as constants:
FB_Base_uri = 'https://veriyo.firebaseio.com/'
FB_Firebase = Firebase::Client.new(FB_Base_uri)
