This JavaScript code uses the Mocha testing framework to test two functions, listDrive and insertPermission, which interact with the Google Drive API. The test calls listDrive to retrieve files, filters the result to include only "Untitled" files, and then concurrently calls insertPermission for each of these files with a specific email address.

Run example

npm run import -- "test list google drive"

test list google drive

var importer = require('../Core');
var listDrive = importer.import("list google drive files");
var insertPermission = importer.import("insert google drive permissions");

describe('list google drive files', () => {
    
    it('should list files', () => {
        return listDrive()
            .then(r => importer
                  .runAllPromises(r.filter(r => r.name.includes('Untitled'))
                                           .map(f => resolve => insertPermission(f.id, 'megamindbrian@gmail.com')
                                                .then(resolve))))
    })
})

// Importing required modules
const importer = require('../Core');
const listDrive = importer.import('listGoogleDriveFiles');
const insertPermission = importer.import('insertGoogleDrivePermissions');

// Defining test suite for listing Google Drive files
describe('listGoogleDriveFiles', () => {
  // Test case to verify file listing functionality
  it('should list files', async () => {
    // Retrieve a list of Google Drive files
    const { files } = await listDrive();

    // Filter files by name (e.g., 'Untitled')
    const untitledFiles = files.filter((file) => file.name.includes('Untitled'));

    // Insert permissions for each 'Untitled' file
    const promises = untitledFiles.map((file) => insertPermission(file.id,'megamindbrian@gmail.com'));
    await Promise.all(promises);
  });
});

Code Breakdown

This code is written in JavaScript using the Mocha testing framework.

Importing Modules

var importer = require('../Core');
var listDrive = importer.import('list google drive files');
var insertPermission = importer.import('insert google drive permissions');

• require('../Core') imports a module named Core from a parent directory.
• importer.import() imports two functions from the Core module: listDrive and insertPermission. These functions are likely used for interacting with the Google Drive API.

Writing a Test

describe('list google drive files', () => {
    
    it('should list files', () => {
        return listDrive()
           .then(r => importer
                 .runAllPromises(r.filter(r => r.name.includes('Untitled'))
                                          .map(f => resolve => insertPermission(f.id,'megamindbrian@gmail.com')
                                               .then(resolve))))
    })
})

• describe is a function from Mocha that groups related tests together.
• it is a function from Mocha that defines a single test case.
• listDrive() is called and its result is awaited.
• The result is then filtered to only include files with the name "Untitled".
• For each of these files, insertPermission is called with the file's ID and an email address, and the result is awaited.
• runAllPromises is likely a function from the Core module that runs all the promised operations concurrently.
• The then clause is used to handle the result of the operation, but it is empty, which means the test does not verify whether the operation was successful.
