#Fetch-Favicon Tests

##Adding a new test case

Upon finding a website that does not return the desired results:

Copy the source of the website into a file in the ./test/unit/icon/ folder.

Add a record to .test/unit/icon/test-cases.json:

[
    {
        "fileName": "" //Name of the source file under test
        "response": "http://example.com/myicon.png" //The desired result image url
    }
]

Run npm run test to see the test fail.
Reduce the source of the website for simplicity, while not changing the nature of the failure. Usually you can:
- Remove the entire <body>
- Remove all <script> tags
- Remove/obfuscate all of the text content.
Fix the the test.
Re-run tests.
