• I have run the command in verbose mode (by adding verbose: true to my config) and pasted the output below:

• I have pasted the contents of my config file below:

browser: "phantomjs"

# (required) The domains to take screenshots of.
domains:
  current:  "https://incedoinc.com"
  new:      "http://14.141.217.200"

# (required) The paths to capture. All paths should exist for both of the domains specified above.
paths:
  incedoinc.com:     /
  workatincedo:    /workatincedo
  

# (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/wait--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

I'm also having this issue.

I'm using:

• Windows 7
• Wraith v. 4.0.1
• Phantomjs v. 1.9.8

I think my output is the same, but in case it helps, here it is:

• I have validated my config file against YAML Validator to make sure it is valid YAML.
• I have run the wraith info command and pasted the output below:

If I set verbose: false, I am able to execute wraith history configs\history.yaml

I guess there's a problem in the code that prints the debug info?
