我正在MEAN JS堆栈应用程序中运行一个grunt测试，并发现一个我无法解决其原因的问题。
单独运行webdriver-manager，即webdriver-manager start，工作正常，但通过grunt test任务运行似乎失败了。
我也注意到端口不同（不是4444）。不知道如何改变这一点。

这是tests.js（/config/assets/tests.js）的配置：
'use strict';
module.exports = {
tests: {
// client: ['modules/*/tests/client/**/*.js'],
client: ['modules/forum/tests/client/**/*.js'],
// server: ['modules/*/tests/server/**/*.js'],
server: ['modules/forum/tests/server/**/*.js'],
e2e: ['modules/*/tests/e2e/**/*.js']
// e2e: ['modules/forum/tests/e2e/**/*.js']
}
};
我还发现/node_module/protractor/config.json下的量角器的config.json具有以下配置：
{
"webdriverVersions": {
"selenium": "2.47.1",
"chromedriver": "2.19",
"iedriver": "2.47.0"
}
}
这是我自己的protractor.config.js，位于网络应用的根目录中：
'use strict';
// Protractor configuration
var config = {
specs: ['modules/*/tests/e2e/*.js']
};
if (process.env.TRAVIS) {
config.capabilities = {
browserName: 'firefox'
};
}
exports.config = config;
这是量角器的npm描述符（/node_module/protractor/package.json）：

答案 0 :(得分：2)
以下是我最好的猜测：
使用您的IP地址和非4444端口启动selenium独立服务器locally。这意味着您没有选择seleniumAddress: "http://localhost:4444/wd/hub"或directConnect: true。我的下面会有一个代码片段。
如果您是在本地而不是在Travis上发布，那么Protractor将由Chrome browser by default启动。这也意味着您应该已经下载了ChromeDriver。
您应该从Protractor 2.5升级到最新版本。量角器与整个堆栈紧密结合：selenium-webdriver，独立服务器，浏览器驱动程序和浏览器。如果您使用的是最新的浏览器和Protractor 2.5，那么webdriver-manager可能会下载可能与您的浏览器不兼容的旧二进制文件。
以下是代码段：
exports.config = {
// option 1. launches a selenium standalone server. this is helpful if
// you launch it with "webdriver-manager start"
// seleniumAddress: "http://localhost:4444/wd/hub",
//
// option 2. launch browser directly using browser binaries
// directConnect: true,
//
// option 3. do not include either seleniumAddress or directConnect
// and this option will launch the selenium standalone server using
// your ip address.
//
// option 4: launch with saucelabs or browserstack options
}
此文件与您定义配置，仅为travis设置功能并导出配置的文件有关。
'use strict';
// Protractor configuration
var config = {
specs: ['modules/*/tests/e2e/*.js']
};
if (process.env.TRAVIS) {
config.capabilities = {
browserName: 'firefox'
};
}
exports.config = config;
