 ## Usage notes:
 + Coverage runs tests a little more slowly.
 + Coverage launches its own in-process ganache server.
 + You can set [ganache options][1] using the `providerOptions` key in your `.solcover.js` [config][15].
 + Coverage [distorts gas consumption][13]. Tests that check exact gas consumption should be [skipped][24].
