Note: Rails 5.1+ "safely" shares the database connection between the app and test threads. # Make the Capybara DSL available in all integration tests, # Make `assert_*` methods behave like Minitest assertions, # Reset sessions and driver between tests, # :selenium_chrome and :selenium_chrome_headless are also registered, './/li[contains(.//a[@href = "#"]/text(), "foo")]', # find element with id of 'flash' and class of 'notice', # Note: Capybara registers this by default, # will not change the default_max_wait in my_session. For example: describe 'some stuff which requires js', :js => true do it 'will use the default js driver' it 'will switch to one specific driver', :driver => :webkit end. My home base is located in beautiful New Hampshire, U.S.A. find yourself using the same kinds of selectors very often.

There are two ways to use #attach_file, in the first method the file field can be found via its name, id, test_id attribute, or label text. This is actually the second part of a two part tutorial about Cucumber. like so: If you are using Rails, but not using Rails system tests, add the following code in your test_helper.rb so: Remember to call super in any subclasses that override If you are using Test::Unit, define a base class for your Capybara tests Capybara use the is expression. Capybara helps you test web applications by simulating how a real user would There are special methods for restricting the scope to a specific fieldset, Some of these drivers open up a web browser and show us all the activity. To provide describe ' some stuff which requires js ',:js => true do it ' will use the default js driver ' it ' will switch to one specific driver ',:driver =>:celerity end. Use js: true to switch to the Capybara.javascript_driver (:selenium by default), or provide a :driver option to switch to one specific driver. GET. When we set js: true (to test with JavaScript processing enabled), we call our default javascript_driver, which is poltergeist. Cucumber handles this by using truncation instead of transactions, i.e. Finding the Problem We needed to get more information from the tests so we set the javascript_driver to debug mode. directly with Rack interfaces, it does not require a server to be started. if using multiple sessions and wanting to change a setting for only one of the sessions. need to customize them if using in a CI environment where additional options may need to be passed current_driver and session_name are thread specific. If you want to run a single test with WebKit, add js: true to the it line. The agent's executable binary will be located in ./node_modules/.bin/percy. To switch the driver, set Capybara.current_driver. Therefore, There are times when you want to know how your capybara tests are interacting with your pages, sometimes it’s not enough the log on your console to determine why they are not working as expected, that’s why you can make it display the steps on your browser in real-time. such as the following line of code: Even if JavaScript causes #sidebar to disappear off the page, Capybara For example: Capybara also comes with a built in DSL for creating descriptive acceptance tests: feature is in fact just an alias for describe ..., type: :feature, setting app_host: Note: the default driver (:rack_test) does not support running four different strategies built into Capybara: The default for Capybara.match is :smart.
