The code imports necessary modules and functions, defines variables, and sets up a test suite using Mocha to verify that the listGlobalForwards function correctly lists global forwards. The test case calls the function with project and proxy parameters, checks the result, and logs any errors or failures to the console.

Run example

npm run import -- "test global forward"

test global forward

var assert = require('assert');
var importer = require('../Core');
var {listGlobalForwards} = importer.import("list global bucket url map");
var project = 'spahaha-ea443';
var proxy = 'https://www.googleapis.com/compute/v1/projects/spahaha-ea443/global/targetHttpsProxies/thp-0c28d-marketing-site-7b81f-sheet-to-web-com';

describe('listing global forwards', () => {
    it('should list forward', () => {
        return listGlobalForwards(project, proxy)
            .then(ip => {
                console.log(ip);
                assert(Object.keys(ip).length > 0, 'should list forward');
            })
    }).timeout(60000)
    
});

const assert = require('assert');
const { Core } = require('../Core');
const { listGlobalForwards } = Core.import('list global bucket url map');

const PROJECT_ID ='spahaha-ea443';
const PROXY_URL = 'https://www.googleapis.com/compute/v1/projects/spahaha-ea443/global/targetHttpsProxies/thp-0c28d-marketing-site-7b81f-sheet-to-web-com';

/**
 * Test suite for listing global forwards
 */
describe('listing global forwards', () => {
  /**
   * Test case: Should list forward
   * @throws {Error} if no forwards are listed
   */
  it('should list forward', async () => {
    const result = await listGlobalForwards(PROJECT_ID, PROXY_URL);
    assert.ok(Object.keys(result).length > 0, 'Should list forward');
    console.log(result);
  }).timeout(60000); // 1 minute timeout
});

Code Breakdown

Importing Modules

The code starts by importing two modules:

var assert = require('assert');
var importer = require('../Core');

• assert is a built-in Node.js module for making assertions about the state of the program.
• importer is a custom module located in the ../Core directory.

Importing Functions

The code then imports a function listGlobalForwards from the importer module:

var {listGlobalForwards} = importer.import('list global bucket url map');

This function is expected to return a promise that resolves to a list of global forwards.

Variable Definitions

Two variables are defined:

var project ='spahaha-ea443';
var proxy = 'https://www.googleapis.com/compute/v1/projects/spahaha-ea443/global/targetHttpsProxies/thp-0c28d-marketing-site-7b81f-sheet-to-web-com';

• project is a string representing a project ID.
• proxy is a string representing a URL for a target HTTPS proxy.

Test Suite

The code defines a test suite using the describe function from Mocha:

describe('listing global forwards', () => {
    //...
});

Test Case

Inside the test suite, a single test case is defined using the it function from Mocha:

it('should list forward', () => {
    //...
});

This test case is expected to pass if the listGlobalForwards function returns a non-empty object when called with the project and proxy parameters.

Test Implementation

The test case implementation is as follows:

return listGlobalForwards(project, proxy)
   .then(ip => {
        console.log(ip);
        assert(Object.keys(ip).length > 0,'should list forward');
    })

• The listGlobalForwards function is called with the project and proxy parameters, and the result is expected to be a promise that resolves to an object ip.
• The then method is used to handle the resolved promise.
• Inside the then callback, the console.log function is used to print the ip object to the console.
• The assert function is used to check that the ip object has at least one key. If this assertion fails, the test will fail with the error message 'should list forward'.

Timeout

The test case is given a timeout of 60 seconds:

}).timeout(60000)

This means that if the test case takes longer than 60 seconds to complete, it will automatically be considered failed.
