| # Engine Testing | |
| This directory contains the infrastructure for running tests on the engine, | |
| which are most often run by Flutter's continuous integration (CI) systems. | |
| The tests themselves are located in other directories, closer to the source for | |
| each platform, language, and variant. For instance, macOS engine unit tests | |
| written in objective C are located in the same directory as the source files, | |
| but with a `Test` suffix added (e.g. "FlutterEngineTest.mm" holds the tests for | |
| "FlutterEngine.mm", and they are located in the same directory). | |
| ## Testing the Engine locally | |
| If you are working on the engine, you will want to be able to run tests locally. | |
| In order to learn the details of how do that, please consult the [Flutter Wiki | |
| page](https://github.com/flutter/flutter/wiki/Testing-the-engine) on the | |
| subject. |
