What's here?
Welcome! package:test is the standard testing library for Dart and
Flutter. If you have questions about Dart testing, please see the docs for
package:test. package:test_api and package:test_core
are implementation details and generally not user-facing.
package:checks is a relatively new library for expressing test
expectations. It's a more modern version of package:matcher and features a
literate API.
Packages
| Package | Description | Issues | Version |

| checks | A framework for checking values against expectations and building custom expectations. |  |  |
| fake_async | Fake asynchronous events such as timers and microtasks for deterministic testing. | |  |
| matcher | Support for specifying test expectations via an extensible Matcher class. Also includes a number of built-in Matcher implementations for common cases. | |  |
| test | A full featured library for writing and running Dart tests across platforms. | |  |
| test_api | The user facing API for structuring Dart tests and checking expectations. |  | |
| test_core | A basic library for writing tests and running them on the VM. |  | |
