javascript - mocha 从节点红色更改流文件路径

Question

我在使用 mocha 为节点红色节点实现单元测试时遇到问题。

如果我使用“$ sudo mocha -t 3000”运行测试，node-red 无法加载 flow_user.json。因为 mocha 中的选项“3000”被设置为“Flow file:”路径中的目录。

node-opcua-client
✓ copy testfile 'flow/flows_user' (1509ms)
✓ run Node-Red  (1856ms)

在“test.js”中，我打开node-red

RED = require ('/usr/local/lib/node_modules/node-red/red.js');

我错了吗？

感谢您的帮助

您需要查看网站上的 Embedding Node-RED 文档:http://nodered.org/docs/embedding.html

但基本上你应该要求node-red，然后创建一个设置对象来传入

var RED = require('node-red');
...
var server = http.createServer(app);
...
var settings = {
    httpAdminRoot:"/red",
    httpNodeRoot: "/api",
    userDir:"/home/nol/.nodered/",
    flowFile: "flow_user.json",
    functionGlobalContext: { }    // enables global context
};
...
RED.init(server,settings);
