From 01a26e581f977b08de072ce3c40b9adee2ba1c10 Mon Sep 17 00:00:00 2001 From: Edouard CHIN Date: Tue, 3 Apr 2018 21:58:39 -0400 Subject: Implement a way to add browser capabilities: * There is currently no way to define specific browser capabilities since our SystemTest driver override the `option` key [Ref](https://github.com/rails/rails/blob/a07d0680787ced3c04b362fa7a238c918211ac70/actionpack/lib/action_dispatch/system_testing/driver.rb#L35) This option key is used internally by selenium to add custom capabilities on the browser. Depending on the Browser, some option are allowed to be passed inside a hash, the driver takes care of setting whatever you passed on the driver option. An example [here](https://github.com/rails/rails/blob/a07d0680787ced3c04b362fa7a238c918211ac70/actionpack/lib/action_dispatch/system_testing/driver.rb#L35) where you are allowed to pass args such as `--no-sandbox` etc However this behavior was only meant for backward compatibility and as you can see it's deprecated. The non-deprecated behavior is to create a `::Option` object containing all the capabilities we want. This is what we [currently do](https://github.com/rails/rails/blob/a07d0680787ced3c04b362fa7a238c918211ac70/actionpack/lib/action_dispatch/system_testing/browser.rb#L34-L36) when chrome or firefox are in headless mode. This PR allows to pass a block when calling `driven_by`, the block will be pased a `::Option` instance. You can modify this object the way you want by adding any capabilities. The option object will be then passed to selenium. ```ruby driven_by :selenium, using: :chrome do |driver_option| driver_option.add_argument('--no-sandbox') driver_option.add_emulation(device: 'iphone 4') end ``` --- railties/test/application/test_runner_test.rb | 2 ++ 1 file changed, 2 insertions(+) (limited to 'railties/test') diff --git a/railties/test/application/test_runner_test.rb b/railties/test/application/test_runner_test.rb index fda6df500d..954eb68445 100644 --- a/railties/test/application/test_runner_test.rb +++ b/railties/test/application/test_runner_test.rb @@ -742,6 +742,7 @@ module ApplicationTests def test_reset_sessions_before_rollback_on_system_tests app_file "test/system/reset_session_before_rollback_test.rb", <<-RUBY require "application_system_test_case" + require "selenium/webdriver" class ResetSessionBeforeRollbackTest < ApplicationSystemTestCase def teardown_fixtures @@ -826,6 +827,7 @@ module ApplicationTests def test_system_tests_are_run_through_rake_test_when_given_in_TEST app_file "test/system/dummy_test.rb", <<-RUBY require "application_system_test_case" + require "selenium/webdriver" class DummyTest < ApplicationSystemTestCase test "something" do -- cgit v1.2.3
