The test_descriptor package provides a convenient, easy-to-read API for defining and verifying directory structures in tests.

We recommend that you import this library with the d prefix. The d.dir() and d.file() functions are the main entrypoints. They define a filesystem structure that can be created using Descriptor.create() and verified using Descriptor.validate(). For example:

import 'dart:io';

import 'package:test_descriptor/test_descriptor.dart' as d;

void main() {
  test("Directory.rename", () async {
    await d.dir("parent", [
      d.file("sibling", "sibling-contents"),
      d.dir("old-name", [
        d.file("child", "child-contents")

    await new Directory("${d.sandbox}/parent/old-name")

    await d.dir("parent", [
      d.file("sibling", "sibling-contents"),
      d.dir("new-name", [
        d.file("child", "child-contents")

By default, descriptors create entries in a temporary sandbox directory, d.sandbox. A new sandbox is automatically created the first time you create a descriptor in a given test, and automatically deleted once the test finishes running.

This package is term_glyph aware. It will decide whether to use ASCII or Unicode glyphs based on the glyph.ascii attribute.


  • Stop using comment-based generics.


  • Declare support for async 2.0.0.


  • FileDescriptor.validate() now allows invalid UTF-8 files.

  • Fix a bug where DirectoryDescriptor.load() would incorrectly report that multiple versions of a file or directory existed.


  • Initial version.
