| /// A library for declaratively describing a filesystem structure, usually for |
| /// the purpose of creating or validating it as part of a scheduled test. |
| /// |
| /// You can use [dir] and [file] to define a filesystem structure. Then, you can |
| /// call [Entry.create] to schedule a task that will create that structure on |
| /// the physical filesystem, or [Entry.validate] to schedule an assertion that |
| /// that structure exists. For example: |
| /// |
| /// import 'package:scheduled_test/descriptor.dart' as d; |
| /// import 'package:scheduled_test/scheduled_test.dart'; |
| /// |
| /// void main() { |
| /// test('Directory.rename', () { |
| /// d.dir('parent', [ |
| /// d.file('sibling', 'sibling-contents'), |
| /// d.dir('old-name', [ |
| /// d.file('child', 'child-contents') |
| /// ]) |
| /// ]).create(); |
| /// |
| /// schedule(() => |
| /// new Directory('parent/old-name').rename('parent/new-name')); |
| /// |
| /// d.dir('parent', [ |
| /// d.file('sibling', 'sibling-contents'), |
| /// d.dir('new-name', [ |
| /// d.file('child', 'child-contents') |
| /// ]) |
| /// ]).validate(); |
| /// }) |
| /// } |
| /// |
| /// Usually you don't want your tests cluttering up your working directory with |
| /// fake filesystem entities. You can set [defaultRoot] to configure where |
| /// filesystem descriptors are rooted on the physical filesystem. For example, |
| /// to create a temporary directory for each test: |
| /// |
| /// import 'package:scheduled_test/descriptor.dart' as d; |
| /// import 'package:scheduled_test/scheduled_test.dart'; |
| /// |
| /// void main() { |
| /// setUp(() { |
| /// var tempDir; |
| /// schedule(() { |
| /// return new Directory('').createTemp().then((dir) { |
| /// tempDir = dir; |
| /// d.defaultRoot = tempDir.path; |
| /// }); |
| /// }); |
| /// |
| /// currentSchedule.onComplete.schedule(() { |
| /// d.defaultRoot = null; |
| /// return tempDir.delete(recursive: true); |
| /// }); |
| /// }); |
| /// |
| /// // ... |
| /// } |
