A nemo plugin for automated visual testing using Applitools Eyes.

	...
    "nemo": "^1.0.0",

	...

    ...
  },
  "plugins": {

        {

        }
      ]
    }
  }
}

How to use

Once nemo-eyes plugin is registered, eyes namespace will be attached to nemo and methods for visual testing are exposed. Idea is to,

1. Initialize your application and test using nemo.eyes.open('Sample Application','Homepage test');
2. Trigger a visual check using nemo.eyes.checkWindow("PayPal Home Page");. If base image for the window in question is present, new screenshot will be compared against it. Otherwise new screenshot will be saved as a base image
3. Close test and resolved promise will have corresponding results

    nemo.eyes.close().then( function(testResults){
        console.log(testResults.isPassed);
        console.log(testResults.url);
    });

Configuration

Configure nemo-eyes via the arguments section in the plugin configuration as above.

For any Eyes SDK method that can takes string arguments, you can program the Eyes SDK via the sdk section of the arguments object.

If you supply "mock": true or "mock": "true" via the config (as shown above), you can run your scripts without having to duck-type around the eyes calls in your script. This is handy if you're working on other aspects of your script and do not want to incur cost or any latency associated with calling out to Applitools.

Running a sample visual test using Applitools.

1. In order to run a test you need to have an Applitools account (free track is available).
2. Copy your API key from the tutorial page (choose "Automated visual tests", then scroll down to step 4), and set it in nemo examples/config/config.json file.
3. go to the repository's root folder and run node examples/eyesTest.js
