isolated

isolated provides one-time folders for unit tests.

Installation

$ npm install isolated

Quick Start

Using isolated is easy. All you need to do is to add a reference to it within your Node.js application:

const isolated = require('isolated');

Then you can use it within your tests. In its simplest form, isolated provides a one-time folder for your test and guarantees to clean up later.

test('...', async () => {
  const directory = await isolated();
});

Additionally, you may want to specify a file or a directory that isolated shall copy to the one-time directory before running your test.

test('...', async () => {
  const directory = await isolated({
    files: 'foo.txt'
  });
});

If you need to copy multiple files or directories, specify an array instead of a single item.

test('...', async () => {
  const directory = await isolated({
    files: [ 'foo.txt', 'bar.txt' ]
  });
});

Sometimes you may want isolate to preserve the sources' timestamps. For that additionally provide the preserveTimestamps option and set it to true.

test('...', async () => {
  const directory = await isolated({
    files: [ 'foo.txt', 'bar.txt' ],
    preserveTimestamps: true
  });
});
