I have a set of gulp.js targets for running my mocha tests that work like a charm running through gulp-mocha. Question: how do I debug my mocha tests running through gulp? I would like to use something like node-inspector to set break points in my src and test files to see what's going on. I am already able to accomplish this by calling node directly:
node --debug-brk node_modules/gulp/bin/gulp.js test
But I'd prefer a gulp target that wraps this for me, e.g.:
gulp.task('test-debug', 'Run unit tests in debug mode', function (cb) {
// todo?
});
Ideas? I want to avoid a bash
script or some other separate file since I'm trying to create a reusable gulpfile
with targets that are usable by someone who doesn't know gulp.
Here is my current gulpfile.js
// gulpfile.js
var gulp = require('gulp'),
mocha = require('gulp-mocha'),
gutil = require('gulp-util'),
help = require('gulp-help');
help(gulp); // add help messages to targets
var exitCode = 0;
// kill process on failure
process.on('exit', function () {
process.nextTick(function () {
var msg = "gulp '" + gulp.seq + "' failed";
console.log(gutil.colors.red(msg));
process.exit(exitCode);
});
});
function testErrorHandler(err) {
gutil.beep();
gutil.log(err.message);
exitCode = 1;
}
gulp.task('test', 'Run unit tests and exit on failure', function () {
return gulp.src('./lib/*/test/**/*.js')
.pipe(mocha({
reporter: 'dot'
}))
.on('error', function (err) {
testErrorHandler(err);
process.emit('exit');
});
});
gulp.task('test-watch', 'Run unit tests', function (cb) {
return gulp.src('./lib/*/test/**/*.js')
.pipe(mocha({
reporter: 'min',
G: true
}))
.on('error', testErrorHandler);
});
gulp.task('watch', 'Watch files and run tests on change', function () {
gulp.watch('./lib/**/*.js', ['test-watch']);
});
