Q:

npm run custom-tests - sendHttpRequest failed non200Response

I'm trying to setup some SailsJS boilerplate I'm finding on the web.  My code is below, I am thinking it is due to my config in routes where I set:
'GET /.temporary/csrf/token/for/tests': { action: 'security/grant-csrf-token' }

I don't have any thing in api/controllers/ for security/grant-csrf-token, do I have to generate such a thing? 
const sails = require('sails');

before(function(done) {

  // Increase the Mocha timeout so that Sails has enough time to lift, even if you have a bunch of assets. 
  this.timeout(10000);

  try {

    // Note that we mix in env vars, CLI opts, and the .sailsrc file using
    // the `.getRc()` method, if possible.   But also note that we mix in
    // a few additional overrides to remove clutter from test output, ensure
    // we are working with a clean database, etc. 
    const configOverrides = sails.getRc();

    sails.lift(
      {
        // Your sails app's configuration files will be loaded automatically,
        // but you can also specify any other special overrides here for testing purposes. 

        // For example, we might want to skip the Grunt hook,
        // and disable all logs except errors and warnings:
        ...configOverrides,
        hooks: {
          ...configOverrides.hooks,
          grunt: false
        },
        models: {
          ...configOverrides.models,
          migrate: 'drop'
        },
        log: {
          ...configOverrides.log,
          level: 'warn'
        },
        routes: {
          ...configOverrides.routes,
          // Provide a way to get a CSRF token:
          'GET /.temporary/csrf/token/for/tests': { action: 'security/grant-csrf-token' }
        },
        policies: {
          ...configOverrides.policies,
          // Poke a hole in any global policies to ensure the test runner can
          // actually get access to a CSRF token. 
          'security/grant-csrf-token': true,
        },
        datastores: {
          ...configOverrides.datastores,
          default: {
          ...(configOverrides.datastores || {}).default
          // To have the tests run against a local mysql database, for example,
          // add configuration here:  (e.g. uncomment the two lines below)
          // adapter: 'sails-mysql',
          // url: 'mysql://root@127.0.0.1:3306/pba',
          }
        }
      },
      err => {

        if (err) return done(err);

        // First, get a cookie and a CSRF token. 
        sails.helpers.http.sendHttpRequest.with({
          method: 'GET',
          url: '/.temporary/csrf/token/for/tests',
          baseUrl: sails.config.custom.baseUrl
        }).exec((err, serverResponse) => {

          if (err) return done(new Error('Test runner could not fetch CSRF token.\nDetails:\n' + err.stack));

When I run npm run custom-test this I get the following error:
PS C:\Users\Mercurius\Documents\GitHub\Homie-Web> npm run custom-tests

A:

You test fails on retrieving request from GET //.temporary/csrf/token/for/tests while you define your route as GET /.temporary/csrf/token/for/tests
So you definitely call a wrong URL.  It happens while you're using a helper
sails.helpers.http.sendHttpRequest.with({
  method: 'GET',
  url: '/.temporary/csrf/token/for/tests',
  baseUrl: sails.config.custom.baseUrl
})

I guess you either has / in your baseUrl or you add it inside a helper. 
So what you need is just to call the right URL
