Capybara Webkit 1.1.0 has been released and it contains some great new features
like screenshots and better
You’re writing a nice little Capybara spec, and you innocently try to click on something using Capybara that you can see plainly in your browser:
click_on 'Sign Up'
You’re SURE this should work, but Capybara gets sassy:
Failed to click element /html/body/div/button (Capybara::Webkit::ClickFailed)
Introducing Capybara Webkit 1.1.0: ClickSuccess edition
ClickFailed errors are pretty frustrating, and unfortunately there’s no
easy fix. These errors occur when your Capybara driver tries to click on an
element, but it can’t find the element or finds a different element where it
expects the target element to be.
Although we haven’t come up with a definitive fix for these issues, Capybara Webkit includes several changes that will help you to work through them. Let’s run through the above scenario again, this time using the latest release of Capybara Webkit.
First, you attempt to click on the element:
click_on 'Sign Up'
You’ll still get a
ClickFailed error, but this time the error message is much
Failed to click element /html/body/div/button because of overlapping element /html/body/div[@id='myModal']/div/div/div at position 191, 121; (Capybara::Webkit::ClickFailed)
Hey now, that’s interesting! There’s some
div tag with an ID of
where you expect your button to be? That’s something you can work with.
But wait! There’s more!
You’ll also see a line like this:
A screenshot of the page at the time of the failure has been written to /var/folders/5c/h1zzj9wx70n4y1qcvnzy2h8h0000gn/T/click_failed_C10849.png
If you pop open this file, you’ll get to clearly see what Capybara Webkit did when you were trying to click on that button:
There’s even a beautiful mouse cursor illustrating the exact location you attempted to click.
If you’re using Capybara Webkit 1.0.0, you can update easily.
gem 'capybara-webkit', '~> 1.1.0'
Update your bundle:
% bundle update capybara-webkit
And you’re good to go!
We also included a handful of other bugfixes and improvements in this release.
Props go out to Austen Ito, Jon Rowe, Kazuhiro Nishiyama, Kirill Nikitin, Kohei Suzuki, and Matthew Horan for helping out with this release.
