Rails + Capybara: 'Unexpected Alert Open' for Selenium Driver

Try wrapping the code that will initiate the alert prompt inside of an accept_alert block, like this:

it "is successful with deleting a user", js: true do  visit '/users'  expect(User.count).to eq(1)  expect(user.email).to eq("ryan@drake.com")  expect(page).to have_content("Manage Users")  # Change is here:  accept_alert do    click_link 'Delete User'  end  user.reload  visit '/users'  expect(User.count).to eq(0)end

I'm a little concerned that you would want to use an alert rather than a confirmation when deleting a resource, but that's up to you. An alert is just going to tell you that something is going to happen, meanwhile a confirmation allows the user to change their mind by hitting cancel instead of OK. If you use a confirmation modal instead of an alert modal then the accept_alertpart would need to be changed to accept_confirm.

Check out the modal documentation rubydoc for more info.

I just got the same error.

Checking the capybara documentation at rubydoc.info, I found that the following methods solve the issue:

accept_confirm: "Execute the block, accepting a confirm."

dismiss_confirm: "Execute the block, dismissing a confirm."
