我是量角器的新手，也是 gulp 任务的新手。我有 gulp 文件，如下所示：
'use strict';
var global = {
app_files: {
spec: './e2e/**/*_spec.js'
},
folders: {
specs: './specs'
}
};
var gulp = require('gulp');
var jshint = require('gulp-jshint');
var stylish = require('jshint-stylish');
var beautify = require('gulp-jsbeautifier');
var protractor = require('gulp-protractor').protractor;
// Download and update the selenium driver
var webdriver_update = require('gulp-protractor').webdriver_update;
var webdriver_standalone = require('gulp-protractor').webdriver_standalone;
// Downloads the selenium webdriver
gulp.task('webdriver_update', webdriver_update);
// Runs the selenium webdriver
gulp.task('webdriver_standalone', webdriver_standalone);
// Lint spec files
gulp.task('lint', function() {
return gulp.src(global.app_files.specs).pipe(jshint()).pipe(jshint.reporter(stylish)).pipe(jshint.reporter('fail'));
});
// Beautify spec files
gulp.task('beautify', function() {
return gulp.src(global.app_files.specs).pipe(beautify({
config: '.jsbeautifyrc'
})).pipe(gulp.dest(global.folders.specs));
});
gulp.task('e2e:local', ['lint', 'webdriver_update'], function() {
gulp.src([global.app_files.specs], {
read: false
}).pipe(protractor({
configFile: 'protractor.conf.js'
})).on('error', function(e) {
throw e;
});
});
gulp.task('e2e', ['e2e:local']);
但是当我使用 - gulpe2e:local 在量角器中运行时，出现以下错误：
MacBook-Pro:spec sab$ protractor protractor.conf.js -gulpe2e:local

任何帮助将不胜感激。

该错误表明 Protractor 正在尝试连接到 Webdriver，但 TCP 连接被拒绝。这可能是因为网络驱动程序未运行。
您的 gulp 文件定义了启动 webdriver 的任务：
// Runs the selenium webdriver
gulp.task('webdriver_standalone', webdriver_standalone);
运行它：
gulp webdriver_standalone
让它运行，然后运行 gulp 任务来开始测试。
或者，您可以让量角器为您启动和停止网络驱动程序。来自文档 https://github.com/mllrsohn/gulp-protractor:
您有 2 个选项来启动 selenium 服务器。
第一个是让 Protractor 自动处理它，包括在测试完成后停止它。为此，只需指向量角器配置文件中的 selenium jar（您需要相应地更新版本号）而不是地址：
// The file path to the selenium server jar ()
seleniumServerJar: './node_modules/protractor/selenium/selenium-server-standalone-2.45.0.jar',
// seleniumAddress: 'http://localhost:4444/wd/hub',
