Configure Mocha to continually run tests fails

I'm trying to configure mocha to run the tests instead of running manually using the command:

node_modules\.bin\mocha -w

I get the error as below.

D:\Downloads\Bluemix\dw0015a\dw0015a\node_modules\mocha\lib\utils.js:626
    throw new Error("cannot resolve path (or pattern) '" + path + "'");
    ^

Error: cannot resolve path (or pattern) '-w'

Solution

  • I am able to get a behavior similar to what you report is to have the w option preceded by an "en dash" character (Unicode U+2013) rather than a minus character. Like this:

    $ mocha –w
/home/x/local/lib/node_modules/mocha/lib/utils.js:626
        throw new Error("cannot resolve path (or pattern) '" + path + "'");
        ^

Error: cannot resolve path (or pattern) '–w'
    at Object.lookupFiles (/home/x/local/lib/node_modules/mocha/lib/utils.js:626:15)
[... etc ...]

    Make sure you are using the minus character (hex value 0x2d).
