This code tests the streamToGoogle function, which uploads a file to Google Cloud Storage, by asserting that a valid URL is returned after the upload.

Run example

npm run import -- "test upload files to google storage"

test upload files to google storage

var path = require('path');
var assert = require('assert');
var importer = require('../Core');
var streamToGoogle = importer.import("upload files google cloud");

describe('upload google storage', () => {
    
    it('should upload a file to a bucket', () => {
        return streamToGoogle(
            'https://www.sgs.com/-/media/global/images/structural-website-images/hero-images/hero-color-palette.jpg?la=en&hash=70B51DB0FA678306B2EAF2E6C4A725BAB0D12342',
            'sheet-to-web.com')
            .then(url => {
                assert(url.length > 0, 'should have a file url');
            })
    })
    
    
})

const path = require('path');
const { describe, it } = require('mocha');
const assert = require('assert');
const importer = require('../Core');
const { streamToGoogle } = importer.import('upload files google cloud');

describe('upload google storage', () => {
  /**
   * Test suite for uploading a file to Google Cloud Storage
   */

  it('should upload a file to a bucket', async () => {
    // Define the file URL and bucket name
    const fileUrl = 'https://www.sgs.com/-/media/global/images/structural-website-images/hero-images/hero-color-palette.jpg?la=en&hash=70B51DB0FA678306B2EAF2E6C4A725BAB0D12342';
    const bucketName ='sheet-to-web.com';

    try {
      // Upload the file to Google Cloud Storage
      const uploadedUrl = await streamToGoogle(fileUrl, bucketName);

      // Assert that the uploaded URL is not empty
      assert.ok(uploadedUrl,'should have a file url');
    } catch (error) {
      // Rethrow the error to ensure it's caught by the test framework
      throw error;
    }
  });
});

This code defines a test suite using the describe and it functions from a testing framework (likely Jest) to verify the functionality of a function called streamToGoogle.

Here's a breakdown:

1. Dependencies:

   • path: Node.js module for working with file and directory paths.
   • assert: Node.js built-in module for making assertions in tests.
   • importer: A custom module (likely located in ../Core) used to import other functions.
   • streamToGoogle: Function imported from importer to upload files to Google Cloud Storage.

2. Test Suite:

   • describe('upload google storage', () => { ... });: Defines a test suite named "upload google storage".

3. Test Case:

   • it('should upload a file to a bucket', () => { ... });: Defines a test case within the suite named "should upload a file to a bucket".

4. Test Logic:

   • Calls streamToGoogle with a URL of an image and a bucket name.
   • Uses .then to handle the Promise returned by streamToGoogle.
   • Inside the .then block:
     • assert(url.length > 0, 'should have a file url');: Asserts that the returned URL is not empty, ensuring the file was successfully uploaded.

5. Execution:

   • This test suite will likely be executed by a testing framework, which will run the test case and report whether it passed or failed based on the assertions.

In essence, this code tests the functionality of the streamToGoogle function by uploading a file to a Google Cloud Storage bucket and verifying that a valid URL is returned.
