copied!<p>I was able to make it work on windows by changing a couple of mocha source code files. After npm install mocha (in my case I installed it just for my project, not globally):</p> <p>1) First go to <strong>node_modules\mocha\lib\utils.js</strong> find and fix <em>watch</em> function as follows:</p> <pre><code>exports.watch = function(files, fn) { var options = { interval: 100 }; files.forEach(function(file) { debug('file %s', file); fs.watch(file, options, function(curr, prev) { fn(file); }); }); }; </code></pre> <p>I replaced fs.watchFile with fs.watch (see <a href="https://github.com/fgnass/node-dev/issues/26" rel="nofollow noreferrer">https://github.com/fgnass/node-dev/issues/26</a> for details) because the first one doesn't seem to work on windows.</p> <p>2) Now open <strong>node_modules\mocha\bin\_mocha</strong> and apply following fixes:</p> <p>a) Find and comment out or remove following code:</p> <pre><code>process.on('SIGINT', function(){ showCursor(); console.log('\n'); process.exit(); }); </code></pre> <p>Since there's no equivalent of POSIX signals lines above have to be removed (ideally replaced by proper implementation, see <a href="https://stackoverflow.com/questions/10021373/what-is-the-windows-equivalent-of-process-onsigint-in-node-js">What is the Windows equivalent of process.on('SIGINT') in node.js?</a> for more details)</p> <p>b) Find following code <em>utils.watch(watchFiles, function(){...</em> and replace it with </p> <pre><code> var lastRun = new Date(); utils.watch(watchFiles, function(){ if (new Date() - lastRun > 300) { purge(); stop() mocha.suite = mocha.suite.clone(); ui = interfaces[program.ui](mocha.suite); loadAndRun(); lastRun = new Date(); } }); </code></pre> <p>It throttles excessive callacks from fs.watch.</p> <p>c) Last change is removing or commenting out this line:</p> <pre><code> process.stdout.write('\r' + str); </code></pre> <p>in <em>function play(arr, interval)</em>. It just removes noise.</p>
