2module ActiveSupport3 # A typical module looks like this:4 #5 # module M6 # def self.included(base)7 # base.extend ClassMethods8 # base.class_eval do9 # scope :disabled, -> { where(disabled: true) }10 # end11 # end12 #13 # module ClassMethods14 # ...15 # end16 # end17 #18 # By using <tt>ActiveSupport::Concern</tt> the above module could instead be19 # written as:20 #21 # require "active_support/concern"22 #23 # module M24 # extend ActiveSupport::Concern25 #26 # included do27 # scope :disabled, -> { where(disabled: true) }28 # end29 #30 # class_methods do31 # ...32 # end33 # end34 #35 # Moreover, it gracefully handles module dependencies.

how to scroll with selenium
What are some alternatives to Selenium?
A proper way to do it for all js tests is to add following inside spec_helper.rb
RSpec.configure
block
config.before(:each, js: true) do
Capybara.page.driver.browser.manage.window.maximize
end
to maximize the window. Change to resize_to(x,y)
to set any window size.
EDIT: If you happen to be using Poltergeist the correct way to do it is
config.before(:each, js: true) do
Capybara.page.driver.browser.resize(x,y)
end

How many times have you come across products that have good UI but really bad functionality such as severe lagging experience and ample number of bugs or vice-versa. There could be multiple reasons for the product to go live, but it definitely gives an indication that thorough testing was not performed. There could be scenarios where a minor software update which was not tested for all the ‘corner scenarios’ could break the existing functionalities in a software product.
Node js has become one of the most popular frameworks in JavaScript today. Used by millions of developers, to develop thousands of project, node js is being extensively used. The more you develop, the better the testing you require to have a smooth, seamless application. This article shares the best practices for the testing node.in 2019, to deliver a robust web application or website.

Verification and Validation, both are important testing activities that collectively define all the mandatory testing activities a tester along with the entire team needs to perform when you are developing a website for either your organization or for the client. For testers, especially those who are new in the industry, understanding the difference between test verification vs validation in website testing may seem to be a bit complex. Because both involve checking whether the website is being developed in the right manner. This is also why I have observed a lot of ambiguity among the teams working on a project.
