Currently, I have a ruby on rails app which includes a dashboard that was created in Google Data Studio and embedded into it.
However, while doing tests on it, I realised that I'm unable to view the resources within the embedded iframe. Is there any way to access this, by perhaps editing the env.rb file?
features/support/env.rb
require 'cucumber/rails'
ActionController::Base.allow_rescue = false
begin
DatabaseCleaner.strategy = :transaction
rescue NameError
raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it."
end
Cucumber::Rails::Database.javascript_strategy = :truncation
Cucumber::Rails::World.use_transactional_tests = false
Capybara.ignore_hidden_elements = false
You need to use within_frame to move the current context into an embedded iframe - https://rubydoc.info/github/teamcapybara/capybara/Capybara/Session#within_frame-instance_method

When I run my rspec tests, many fail due to stale data in my mongodb database. AFAIK it is far better to test with a clean database.
How can I clean and/or re-seed the database before each test?
You can use database_cleaner gem to accomplish this task.
From their documentation:
RSpec.configure do |config|
config.use_transactional_fixtures = false
config.before(:suite) do
DatabaseCleaner.clean_with(:truncation)
end
config.before(:each) do |example|
DatabaseCleaner.strategy= :truncation
DatabaseCleaner.start
end
config.after(:each) do
DatabaseCleaner.clean
end
end
As you are using Mongoid ORM, you may also need to specify it explicitly:
# How to setup your ORM explicitly
DatabaseCleaner[:mongoid].strategy = :truncation
Update:
I see an open issue for MongoID 5
To make it work, you can monkey patch the Mongo Ruby driver class as mentioned in the issue.
module Mongo
class Collection
class View
def remove_all
remove(0)
end
end
end
end
Athough it's not a great solution!
The fix to the problem is there in the master branch of database_cleaner(1.4.1) gem. Install the gem from master to fix the problem (until there is the version bump). Expected to get fixed in next version.
gem 'database_cleaner', :git => 'https://github.com/DatabaseCleaner/database_cleaner.git'
I'm using rspec-rails to test a controller in my rails application. In one instance, I'm creating new objects to test that they're properly assigned to instance variables.
describe MainController do
describe "GET #index" do
it "properly assigns a colored ball" do
ball1 = Ball.create(color: 'red')
get :index
expect(assigns(:red_balls)).to eq([ball1])
end
end
end
When I run the test, does rspec access the database to create ball1 and then delete it once the test is run?
From the snippet in your question, Yes Rspec access the DB configured as test in the database.yml file, if you want to clean out the DB/Records created by Rspec you can use the database_cleaner gem you can configure it as you deem fit.
e.g:
add gem database_cleaner to your Gemfile
and the below to your spec_helper.rb file as specified by the database_cleaner documentation:
RSpec.configure do |config|
config.before(:suite) do
DatabaseCleaner.strategy = :transaction
DatabaseCleaner.clean_with(:truncation)
end
config.before(:each) do
DatabaseCleaner.start
end
config.after(:each) do
DatabaseCleaner.clean
end
end
Then database_cleaner would truncate the tables in the test db and leave them in a pristine state
To add to what bjhaid said above - Rspec should only be accessing you 'test' database. Check out the config/database.yml to see the configuration of your different databases.
So you do not have to worry about things in your development or production databases interfering with your testing database.
Yes, RSpec allows your database calls to go through, but with the rspec-rails gem under the default configuration, it will execute each test within a database transaction and will roll back that transaction at the end of each example with no action required on your part. No additional gem is required. See https://relishapp.com/rspec/rspec-rails/docs/transactions.
Am trying to work on coverband gem that will show the code covered in my application. I followed commands from this link https://github.com/danmayer/coverband, and used "rake test" to generate coverage. Added
require 'simplecov'
SimpleCov.start
to test/test_helper.rb and config/application.rb as in simplecov gem documentation. My question is how to get output for the entire clicks and adds that i do on my application? For now i end up with output on initializers and configs but i need codes covered for controllers, models and views.
Would somebody help with this ?
Hey I am the author of Coverband. I wanted to help make sure people understand that Coverband isn't for test code coverage. For that you should just look at Simplecov which has all you need. Coverband, provides runtime code coverage, which is useful for seeing what code is executed on production servers. This helps find features and code that is being maintained but isn't in use by any actual users. The use case from Simplecov is very different. Coverband uses the Simplecov output formatters, but besides that they don't share other code or the same goals.
Hope that helps.
I managed to get a working spec/spec_helper.rb configuration that executes SimpleCov correctly simply using the $ rspec spec/ command thanks to a comment on the Github issue that sent me to this blog entry, and its example spec/spec_helper.rb. All reasons why this works are contained in the (very detailed!) blog entry. Replace SampleApp with the name of your application
Spork.prefork do
unless ENV['DRB']
require 'simplecov'
SimpleCov.start 'rails'
end
require 'rails/application'
require Rails.root.join("config/application")
ENV["RAILS_ENV"] ||= 'test'
require 'rspec/rails'
require 'rspec/autorun'
RSpec.configure do |config|
config.mock_with :rspec
config.fixture_path = "#{::Rails.root}/spec/fixtures"
config.use_transactional_fixtures = false
config.before :each do
if Capybara.current_driver == :rack_test
DatabaseCleaner.strategy = :transaction
else
DatabaseCleaner.strategy = :truncation
end
DatabaseCleaner.start
end
config.after do
DatabaseCleaner.clean
end
config.infer_base_class_for_anonymous_controllers = false
end
end
You might try using Cucumber with a Web driver. That should get clicks in the coverage report. If you need Javascript evaluation, you'll want to use Selenium.
I am new to rails. i try to write test for a model for that i use factory-girl gem. In that data was taken from XML file.
My problem is when ever am running my rspec file, data was appended every time, in XML file i have only 32 data, but every time am executing rsepc data was increasing...
i even tried database_cleaner but same result.
I want to delete the data in factory-girl.
is there anyway to avoid duplication in factory-girl?
is there anyway to use where condition like query for factory-girl?
Thank you.
Try this:
The following things use to reset factory girl data.
Add following line in your Gemfile and try bundle install.
gem "database_cleaner", ">= 0.8.0", :group => :test
In spec_helper.rb:
RSpec.configure do |config|
# Other things
# Clean up the database
require 'database_cleaner'
config.before(:suite) do
DatabaseCleaner.strategy = :truncation
DatabaseCleaner.orm = "mongoid"
end
config.before(:each) do
DatabaseCleaner.clean
end
end
I'm running rails 3.0.3 and using rspec-rails 2.4.1 with a postgresql database. Whenever I run my RSpec tests, the data remains at the end. Does anyone know how to get rails or rspec to wipe the test environment's data between each use?
Please tell me if there's any further information that could make answering my question easier.
Thanks!Tristan
Install the database_cleaner gem and then add this to your spec_helper.rb.
Spec::Runner.configure do |config|
config.before(:suite) do
DatabaseCleaner.strategy = :transaction
DatabaseCleaner.clean_with(:truncation)
end
config.before(:each) do
DatabaseCleaner.start
end
config.after(:each) do
DatabaseCleaner.clean
end
end
Use transactional examples to rollback the data after every test run
RSpec.configure do |config|
config.use_transactional_examples = true
end
You don't need any extra gem in order to clean your test DB between runs. In your spec_helper.rb file, configure rspec as follows:
RSpec.configure do |c|
c.around(:each) do |example|
ActiveRecord::Base.connection.transaction do
example.run
raise ActiveRecord::Rollback
end
end
end
Another possibility, that I just put myself through, is using the wrong before block.
I accidentally set a before block as an all instead of an each:
before :all do
user = FactoryGirl.create(:user)
sign_in user
end
This caused the user to stick around in the database for the entire rspec run, which caused validation collisions.
Instead, the before should be an each so that everything is kept clean through the rspec run:
before :each do
user = FactoryGirl.create(:user)
sign_in user
end
If you've made this mistake, then you will probably need to manually clean up your test database before things go back to normal. The simplest way to do that is probably to truncate each of the tables (aside from schema_migrations).
