+# Native Pigeon Tests
+
+This directory contains native test harnesses for native and end-to-end tests
+of Pigeon-generated code. The [test script](../tool/run_tests.dart) generates
+native code from [pigeons/](../pigeons/) into the native test scaffolding, and
+then drives the tests there.
+
+To run these tests, use [`run_tests.dart`](../tool/run_tests.dart)
+
+## test\_plugin
+
+The new unified test harness for all platforms. Tests in this plugin use the
+same structure as tests for the Flutter team-maintained plugins, as described
+[in the repository documentation](https://github.com/flutter/flutter/wiki/Plugin-Tests).
+
+## alternate\_language\_test\_plugin
+
+The test harness for alternate languages, on platforms that have multiple
+supported plugin languages. It covers:
+- Java for Android
+- Objective-C for iOS
+
+## flutter\_null\_safe\_unit\_tests
+
+Dart unit tests for null-safe mode. This is a legacy structure from before
+NNBD was the only mode Pigeon supported; these should be folded back into
+the main tests.

-description: A new Flutter project.
-publish_to: none
-
-# The following defines the version and build number for your application.
-# A version number is three numbers separated by dots, like 1.2.43
-# followed by an optional build number separated by a +.
-# Both the version and the builder number may be overridden in flutter
-# build by specifying --build-name and --build-number, respectively.
-# In Android, build-name is used as versionName while build-number used as versionCode.
-# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
-# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
-# Read more about iOS versioning at
-# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html
-version: 1.0.0+1
-
-environment:
-  sdk: ">=2.12.0 <3.0.0"

-# For information on the generic Dart part of this file, see the

-
-# The following section is specific to Flutter.
-flutter:
-
-  # The following line ensures that the Material Icons font is
-  # included with your application, so that you can use the icons in
-  # the material Icons class.
-  uses-material-design: true
-
-  # To add assets to your application, add an assets section, like this:
-  # assets:
-  #  - images/a_dot_burr.jpeg
-  #  - images/a_dot_ham.jpeg
-
-  # An image asset can refer to one or more resolution-specific "variants", see
-  # https://flutter.dev/assets-and-images/#resolution-aware.
-
-  # For details regarding adding assets from package dependencies, see
-  # https://flutter.dev/assets-and-images/#from-packages
-
-  # To add custom fonts to your application, add a fonts section here,
-  # in this "flutter" section. Each entry in this list should have a
-  # "family" key with the font family name, and a "fonts" key with a
-  # list giving the asset and other descriptors for the font. For
-  # example:
-  # fonts:
-  #   - family: Schyler
-  #     fonts:
-  #       - asset: fonts/Schyler-Regular.ttf
-  #       - asset: fonts/Schyler-Italic.ttf
-  #         style: italic
-  #   - family: Trajan Pro
-  #     fonts:
-  #       - asset: fonts/TrajanPro.ttf
-  #       - asset: fonts/TrajanPro_Bold.ttf
