Installation

Add this line to your application's Gemfile:

gem 'poltergeist-suppressor'

And then execute:

$ bundle

Or install it yourself as:

$ gem install poltergeist-suppressor

Usage

Add these lines to spec_helper.rb:

require 'capybara/poltergeist'
require 'poltergeist/suppressor'

This gem automatically set a suppressed driver to :poltergeist.

You can manually add a suppressor to your driver.

Capybara.register_driver :poltergeist do |app|
  Capybara::Poltergeist::Driver.new(app,
    phantomjs_logger: Capybara::Poltergeist::Suppressor.new
  )
end

And you can specify ignore patterns in regexp.

suppressor = Capybara::Poltergeist::Suppressor.new(patterns: [
  /spam spam spam spam/,
  /spamspamspamspam/
])

Capybara.register_driver :poltergeist do |app|
  Capybara::Poltergeist::Driver.new(app, phantomjs_logger: suppressor)
end
