Check Alert Message with Poltergeist or Capybara Webkit

Use accept_alert to get the alert message.

  • Poltergeist ignores alerts/confirms by default(source)
  • Poltergeist has had support for Capybaras modal api since September 2015( source)

That means you can same syntax for Poltergeist or capybara-webkit.

expect(accept_alert).to eq("Javascript alert message")

# or with block syntax

# will fail if alert message doesn't match
accept_alert("Javascript alert message") do 
  # next expectation
end

The first one expect(accept_alert).to reads a bit weird, but that's the return value of accept_alert.

I got a brand new Mac Air recently, when I tried to install

The Error

Got this error when bundle install one rails app.

An error occurred while installing capybara-webkit (0.12.1), and Bundler cannot continue.
Make sure that `gem install capybara-webkit -v '0.12.1'` succeeds before bundling.

Tried brew install qt didn’t get luck, raised this error:

Solution

Checked all those links and tried several things, eventually downloading
qt installer from the qt-project website solved my problem.


Download link

Just install the debug libraries, qt libraries then bundle install
again.

Note

If you already got qt installed and capybara-webkit worked before
upgrade to Mavericks, then it’s probably gonna work as well.
