This code tests a de-linting service by exporting and deploying a module, de-linting a project directory, and verifying the process's successful completion.

Run example

npm run import -- "test de-linting service"

test de-linting service

var fs = require('fs');
var importer = require('../Core');
var delint = importer.import("delint notebooks");
var exportAndDeploy = importer.import("export deploy notebook");
var exportNotebook = importer.import("notebook.ipynb[export cells modules");

var PROFILE_PATH = process.env.HOME || process.env.HOMEPATH || process.env.USERPROFILE;
var project = path.resolve(path.join(__dirname, '../Utilities/.modules'));

// just do it in load mode
if(typeof describe === 'undefined') {
    var it = ((l, func) => func());
    it.timeout = () => {};
    var beforeEach = ((func) => func());
    var describe = ((l, func) => func());
//    var describe = (() => {});
}

// TODO: make this a test script for exporting all notebooks on file change watcher
describe('de-linting service', () => {
    it('should de-lint a file', () => {
        const r = importer.interpret('diff code blocks');
        assert(r.filename.indexOf('diff.ipynb') > -1);
        return exportAndDeploy(['delint notebooks'])
            .then(() => exportNotebook(__filename))
            .then(() => delint(project))
            .then(r => {
                //console.log(r);
                //var filename = path.join(project, 'Utilities/diff/cell-' + cell.to + '.js');
                //return diffTwoTexts(cell.code, fs.readFileSync(filename).toString());
            })
            .catch(r => console.log(r))
    }).timeout(30000);
})

// Import required modules
const fs = require('fs');
const path = require('path');
const importer = require('../Core');

// Define constants
const PROFILE_PATH = process.env.HOME || process.env.HOMEPATH || process.env.USERPROFILE;
const PROJECT_PATH = path.resolve(path.join(__dirname, '../Utilities/.modules'));

// Define utility functions
const loadMocha = () => {
  if (typeof describe === 'undefined') {
    const it = (label, func) => func();
    it.timeout = () => {};
    const beforeEach = (func) => func();
    const describe = (label, func) => func();
  }
  return { describe, it, beforeEach };
};

const exportAndDeployNotebook = (project, filename) =>
  exporter && exporter.exportAndDeployNotebook(project, filename);

const delintNotebook = (project) =>
  importer.interpret('diff code blocks').then((result) => importer.delint(project, result.filename));

// Main test suite
const exporter = importer.import('export deploy notebook');
const delint = importer.import('delint notebooks');
const exportNotebook = importer.import('notebook.ipynb[export cells modules]');

describe('de-linting service', () => {
  // Load mocha environment if necessary
  const mocha = loadMocha();

  mocha.describe('export and deploy', () => {
    it('should export and deploy a notebook', () => {
      return exportAndDeployNotebook(PROJECT_PATH, __filename).then(() => {
        return delintNotebook(PROJECT_PATH);
      }).then((results) => {
        // console.log(results);
      }).catch((error) => {
        console.error(error);
      });
    });
  }).timeout(30000);
});

This code defines a test suite for a de-linting service within a project.

Here's a breakdown:

1. Initialization:

   • Imports necessary modules: fs for file system operations, importer for loading project modules, delint for code linting, exportAndDeploy for exporting and deploying notebooks, and exportNotebook for exporting individual notebooks.
   • Sets up environment variables for project paths.

2. Test Environment Setup:

   • Detects if the code is running in a test environment (using describe function) and sets up a basic test environment if not.

3. Test Suite:

   • Defines a test suite named "de-linting service" using describe.
   • Defines a test case "should de-lint a file" using it.

4. Test Case Execution:

   • Calls importer.interpret to interpret code blocks and asserts that the filename contains "diff.ipynb".
   • Calls exportAndDeploy to export and deploy the "delint notebooks" module.
   • Calls exportNotebook to export the current file.
   • Calls delint to de-lint the project directory.
   • Handles the result of the de-linting process, logging any errors.

In essence, this code tests the functionality of a de-linting service by exporting and deploying a module, de-linting a project directory, and asserting that the process completes successfully.
