This is an example configuration provided by Wraith.

Feel free to amend for your own requirements.

This particular config is intended to demonstrate how

to use Wraith in 'capture' mode, which is best suited to

comparing a test and live version of the same website.

wraith capture capture.yaml

##############################################################
##############################################################

(required) The engine to run Wraith with. Examples: 'phantomjs', 'casperjs', 'slimerjs'

browser: "phantomjs"

(required) The domains to take screenshots of.

domains:
my_site: "http://www.example.com"
my_other_site: "http://www.test.example.com"

(required) The paths to capture. All paths should exist for both of the domains specified above.

paths:
#home: /
#about: /about
#contact: /get-in-touch

(required) Screen widths (and optional height) to resize the browser to before taking the screenshot.

screen_widths:

• 320
• 600x768
• 768
• 1024
• 1280

(optional) JavaScript file to execute before taking screenshot of every path. Default: nil

before_capture: 'javascript/disable_javascript--phantom.js'

(required) The directory that your screenshots will be stored in

directory: 'shots'

(required) Amount of fuzz ImageMagick will use when comparing images. A higher fuzz makes the comparison less strict.

fuzz: '20%'

(optional) The maximum acceptable level of difference (in %) between two images before Wraith reports a failure. Default: 0

threshold: 5

(optional) Specify the template (and generated thumbnail sizes) for the gallery output.

gallery:
template: 'slideshow_template' # Examples: 'basic_template' (default), 'slideshow_template'
thumb_width: 200
thumb_height: 200

(optional) Choose which results are displayed in the gallery, and in what order. Default: alphanumeric

Options:

alphanumeric - all paths (with or without a difference) are shown, sorted by path

diffs_first - all paths (with or without a difference) are shown, sorted by difference size (largest first)

diffs_only - only paths with a difference are shown, sorted by difference size (largest first)

Note: different screen widths are always grouped together.

mode: diffs_first

(optional) Set the number of threads to use when saving images. Raising this value can improve performance, but very high

values can lead to server connection issues. Set to around 1.5 the available CPU cores for best performance. Default: 8

threads: 8
verbose: true
