使用selenium驱动程序运行node-red

Question

我将运行mocha测试套件来测试节点红色节点。因此我使用mocha和selenium驱动程序。

我有一个问题，运行节点红色模块。如果我用$ mocha --ui **tdd**开始测试，节点红色的应用程序找不到我的流程。因为他正在文件夹"~/.node-red/tdd"中搜索。我不知道为什么mocha [option]被设置为路径?仅用命令$ mocha不能定义suite();的功能?

我会用我自己的设置来解决init node-red的问题。像这样…http://nodered.org/docs/embedding.html

通过这种方式，我可以在'RED.start()'之后运行node-red，但我没有URL，无法在selenium驱动程序中打开node-red ?

require('colors');
var async = require ('async');
var fs = require('fs');
var node = require ('../../mynode.js');
var assert = require('node-assertthat');
var http = require('http');
var http = require('http');
var express = require("express");
var RED = require("node-red");
// Create an Express app
var app = express();
// Add a simple route for static content served from 'public'
app.use("/",express.static("public"));
// Create a server
var server = http.createServer(app);

var settings = {
    settingsFile:"/usr/local/lib/node_modules/node-red/settings.js",
    userDir:"/home/<user>/.nodered",
    flowFile: "flow_<name>.json",
    functionGlobalContext: { }    // enables global context
};
// Initialise the runtime with a server and settings
RED.init(server,settings);

var webdriver = require('../'),
            By = webdriver.By,
            until = webdriver.until;
/* connect to selenium browser */
driver = new webdriver.Builder()
        .forBrowser('chrome')
       .build();

suite('node', function(){
        var driver;
    suite('test setup', function(){
    suite('connect to http://127.0.0.1:1880', function(){       
        setup(function(){
        });    
        test('run Node-Red ',function(done){
            setTimeout(function(){
                /* run node-red */
                RED.start();
                done();
            },2000);    
        });
        test('open URL 'http://localhost:1880/#'', function(done) {
            setTimeout(function(){
                driver.get('http://localhost:1880/#');
                /* open node-red URL */     
                driver.getTitle().then(function(title) {
            console.log('nPage title is: '+ title.red.bold +"n");
            assert.that(title, is.equalTo('Node-RED'));
            done();
                });
            },2000);
        });
});

已设置默认路由

app.use("/",express.static("public"));

这将与Node-RED冲突，除非你将Node-RED路由设置为不同的东西。

你需要在你的设置中设置httpNodeRoot和httpAdminRoot，例如

var settings = {
    settingsFile:"/usr/local/lib/node_modules/node-red/settings.js",
    userDir:"/home/<user>/.nodered",
    flowFile: "flow_<name>.json", 
    httpAdminRoot:"/red",
    httpNodeRoot: "/api",
    functionGlobalContext: { }    // enables global context
};

如果你这样做，那么你将在本地主机上访问Node-RED，如下所示:

http://localhost: 1880/红

编辑:只有在使用httpIn节点

问题是'var driver'在第一个'suite()'中，我初始化了一个新的'var驱动器'，并覆盖了第一个。那是个愚蠢的错误。

...
 suite('node', function(){
--        var driver;
++        //var drive;
...
