使用gulp运行量角器和硒时出现的问题

Question

我对量角器很陌生，对吞咽任务也很陌生，我有一份像这样的文件：

    '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，当我在量角器中运行时，使用-grape2e:local，我得到了以下错误：

MacBook-Pro:spec sab$ protractor protractor.conf.js -gulpe2e:local

任何帮助都是非常感谢的。

谢谢

此错误表示量角器试图连接到TCP驱动程序，而TCP连接被拒绝。这可能是因为webdriver没有运行。

gulp文件定义了启动for驱动程序的任务：

// Runs the selenium webdriver
gulp.task('webdriver_standalone', webdriver_standalone);

要运行它：

gulp webdriver_standalone

继续运行它，然后运行gulp任务来启动测试。

或者，您可以让量角器启动和停止为您的网络驱动器。来自文档

您有两个选项来启动selenium服务器。 第一种方法是让Protractor自动处理它，包括在测试完成后停止它。要做到这一点，只需指向protractor配置文件中的selenium jar (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',
