Question

我为单元测试创建了gulp任务。我添加nodemon以自动运行服务器然后运行测试。但是再次运行gulp任务时会出错。我有错误说端口已经忙于另一个进程。

我使用此代码：

.slide-in-right {
  -webkit-transform: translateX(100%);
    transform: translateX(100%); }

.slide-in-right.ng-enter, .slide-in-right > .ng-enter {
  -webkit-transition: all cubic-bezier(0.1, 0.7, 0.1, 1) 2000ms;
  transition: all cubic-bezier(0.1, 0.7, 0.1, 1) 2000ms; }

.slide-in-right.ng-enter-active, .slide-in-right > .ng-enter-active {
  -webkit-transform: translateX(0);
    transform: translateX(0); }

.slide-in-right.ng-leave, .slide-in-right > .ng-leave {
  -webkit-transition: all linear 2800ms;
  transition: all linear 2800ms; }

如何在单元测试后停止或终止服务器？

除了答案： 现在我有gulpfile.js：

var gulp = require('gulp'),
    gulpUtil = require('gulp-util'),
    gulpShell = require('gulp-shell'),
    gulpEnv = require('gulp-env'),
    gulpNodemon = require('gulp-nodemon'),
    gulpMocha = require('gulp-mocha');

gulp.task('default', function () {
    gulpUtil.log('unit - run unit tests');
});

gulp.task('server', function (callback) {
    var started = false;

    return gulpNodemon({
        script: './build/app.js'
    })
        .on('start', function () {
            if (!started) {
                started = true;

                return callback();
            }
        })
});

gulp.task('unit', ['server'], function () {
    return gulp.src('./src/*.js')
        .pipe(gulpMocha({reporter: 'spec'}))
        .once('error', function () {
            process.exit(1);
        })
        .once('end', function () {
            process.exit();
        })
});

同样在我的服务器脚本中，我添加了以下代码段：

var gulp = require('gulp'),
    gulpUtil = require('gulp-util'),
    gulpNodemon = require('gulp-nodemon'),
    gulpMocha = require('gulp-mocha'),
    gulpShell = require('gulp-shell');
var runSequence = require('run-sequence');
var nodemon;

gulp.task('default', function () {
    gulpUtil.log('compile - compile server project');
    gulpUtil.log('unit - run unit tests');
});

gulp.task('compile', function () {
    return gulp.src('./app/main.ts')
        .pipe(gulpShell([
            'webpack'
        ]))
});

gulp.task('server', function (callback) {
    nodemon = gulpNodemon({
        script: './build/app.js'
    })
        .on('start', function () {
            return callback();
        })
        .on('quit', function () {
        })
        .on('exit', function () {
            process.exit();
        });

    return nodemon;
});

gulp.task('test', function () {
    return gulp.src('./src/*.js')
        .pipe(gulpMocha({reporter: 'spec'}))
        .once('error', function () {
            nodemon.emit('quit');
        })
        .once('end', function () {
            nodemon.emit('quit');
        });
});


gulp.task('unit', function() {
    runSequence('compile', 'server', 'test');
});

因此，当测试结束并在服务器脚本中调用this.appListener = this.http.listen(process.env.PORT || 3000, '0.0.0.0', function() { console.log(chalk.green("Server started with port " + _this.appListener.address().port)); }); // **Add** function stopServer() { console.log(chalk.cyan('Stop server')); process.exit(); } process.on('exit', stopServer.bind(this)); process.on('SIGINT', stopServer.bind(this));时，我添加了事件 exit 事件处理程序，该服务器停止服务器并且gulp任务已成功完成停止服务器。

Nodemon有一个quit命令。请查看Using nodemon events并了解您的模块docs。根据您可以使用的文档：

var nodemon = require('nodemon');

// force a quit
nodemon.emit('quit');

无法通过nodemon停止服务器运行
