Prompt to run truffle init

If I run solidity-coverage in a directory where truffle hasn’t been initialised, I get:

Generating coverage environment
ls: no such file or directory: ./coverageEnv/contracts/**/*.sol
Launched testrpc on port 8555
Running: truffle test
(this can take a few seconds)...
/usr/lib/node_modules/truffle/build/cli.bundled.js:213349
      files = files.filter(function(file) {

        There was an error generating coverage. Possible reasons include:
        1. Another application is using port 8555
        2. Truffle crashed because your tests errored

      Error: ENOENT: no such file or directory, open './allFiredEvents'
Exiting without generating coverage...

I’m a noob, but it took me a while to work out what was going on.

Perhaps check if files is undefined and say something like:

"Can’t find truffle files. Have you run “truffle init”?

Welcome 😃 The link I gave says it would be better to use:

Your test runner (Truffle?) crashed because the tests encountered an error.

Perhaps s/crashed/failed/

Will do. Thanks!
