Wraith uses a json based configuration file that allows you specfify a large number of options. You can create as many configurations files as you need and call them from the cli using the --config flag. All congiguration files must be stored within the config folder.
Below is an example configuration file:
{
"project": "Test", (Optional name for the project, if supplied it will be used within the generated gallery only)
Specify one or two domains
"domains": {
"bbb.co.uk": "http://www.bbc.co.uk",
"live.bbc.co.uk": "http://live.bbc.co.uk"
},
Engines supported are phantomjs, slimerjs and triflejs but in theory any phantomjs based headless browser can be supported via a custom snap.js file
"engines" : [
"phantomjs"
],
Specify as many sizes as you wish
"sizes": [
"320",
"768",
"1440"
],
"outputDir": "test/chrome/", (Output directory within the /shots directory)
You can choose to specfiy a list of paths to be used or you can crawl the site. If paths are provided they will take precident and the spider file will be ignored.
"paths": [
"/",
"/news/",
"/news/local/",
"/news/england/york_and_north_yorkshire/",
"/weather/"
],
If no paths are specified then a site crawl will take place and the results will be save in the location specified within this option
"spider": "spider/test.txt", (Specify which file should be used for the spider txt file)
"snap": "snap/test/chrome.js", (Specify snap.js which is used to take the screenshots)
"fuzz": "20%", (Adjusts the sensitivity of the image comparison)
"maxConnections": 20 (Limit the amount of concurrent processes)
