my-own-words/test/remove.test.js

A small tool that I have created to keep safe all those words/expressions that I come across when I'm learning a new language

const os = require('os');

const home = os.homedir();
const route = `${home}\\.my-own-words`;

describe('Before #remove', () => {
  before(() => {
    rimraf.sync(route);
  });

  it('should delete the directory', () => {
    assert.isFalse(dirExists());
  });

  it('should create a clear directory with an empty list', () => {
    const listName = 'italian';

    newList(listName);

    assert.isTrue(dirExists());
    assert.isTrue(listExists(listName));
  });

  it('list should have a word with two definitions', () => {
