Error when using binding.irb, how to make it work ?

[jean-francois-labbe]

Usecase / What to achieve

I'm able to run a test but when I add binding.irb or binding.b in test the test doesn't start at all, same thing with a sleep 3

I tried with PWDEBUG=1 rspec but the error is the same.

Error message is:

Failure/Error: click_on I18n.t('views.sessions.new_account')

Question

What should I do, change in the configuration to be able to use binding.irb ?

[YusukeIwaki]

The behabior is unexpected since I myself use binding.pry for debugging described source codes.

Could you provide an example code for reproducing this issue?

[YusukeIwaki]

This example code doesn't trigger timeout.

$ bundle exec ruby a.rb 
From: /Users/yusuke-iwaki/Desktop/plrb/a.rb:8 :

     3: 
     4: Playwright.create(playwright_cli_executable_path: './node_modules/.bin/playwright-core') do |playwright|
     5:   playwright.chromium.launch(headless: false) do |browser|
     6:     page = browser.new_page
     7:     page.goto('https://github.com/YusukeIwaki')
 =>  8:     binding.pry
     9:     page.screenshot(path: './YusukeIwaki.png')
    10:   end
    11: end

And the provided call stack shows

# /Users/.gem/ruby/3.1.4/gems/capybara-playwright-driver-0.5.1/lib/capybara/playwright/node.rb:363:in `click'

so it is probably capybara-playwright-driver's bug or spec.

[YusukeIwaki]

Sorry for my mistake, I found playwright-ruby-client >= 1.40.0 raises such error after we use wait_for_xxx or expect_xxx methods.
YusukeIwaki/capybara-playwright-driver#72

[jean-francois-labbe]

@YusukeIwaki Sorry for the delay. It looks like you found the cause of the issue. Is there anything I can do do help solve it ?

The spec looks like this:

  it "signed up user" do
    visit root_path

    detected_locale = find("select[name='lang']").value
    switch_locale_to(detected_locale) do
      click_on I18n.t('views.sessions.new_account') # breaks here when binding.b is set under.

      expect(page).to have_current_path(new_user_session_path(lang: detected_locale))
      fill_in 'user_first_name', with: 'John'
      fill_in 'user_last_name', with: 'Doe'
      fill_in 'user_email', with: 'john@email.com'
      fill_in 'user_password', with: 'password'
      click_on I18n.t('views.sessions.sign_up')

      binding.b  # break point is here
      expect(page).to have_content(I18n.t('devise.registrations.signed_up'))
    end
  end

It is specific to the application, if needed I could try to create a minimal repository to reproduce the issue.

What is strange is that the binding.b is declared at the bottom of the test but the execption occurs on this line
click_on I18n.t('views.sessions.new_account')

When there is no binding.b the test is successful.

I tried with playwright-ruby-client version 1.39.1, it is a similar issue.

It may not only be related to the binding.b.

I can have same error when binding.b is removed and launching test with:
PWDEBUG=1 rspec ./spec/features/sign_up_spec.rb:77

and rapidly clicking on the play button.

Sorry for late reply,

I found playwright-ruby-client >= 1.40.0 raises such error after we use wait_for_xxx or expect_xxx methods.
YusukeIwaki/capybara-playwright-driver#72

#292 would fix the issue and playwright-ruby-client 1.41.2 and 1.42.1 include the patch.
binding.pry would be available in the version.

Playwright::Error:
Element is not attached to the DOM

This can be a bug of capybara-playwright-driver, however I recommend using web-first assertion provided by Playwright, instead of Capybara's assertion, if possible.
https://playwright-ruby-client.vercel.app/docs/api/locator_assertions

page.driver.with_playwright_page do |page|
  page.get_by_text(I18n.t('views.sessions.sign_up')).click
  expect(page.locator('.flash')).to have_text(I18n.t('devise.registrations.signed_up'))
end

Playwright's auto-waiting feature is more precise than Capybara's behavior.
