| # UI Tests | |
| These tests are intended to be renderer-agnostic. These tests should not use | |
| APIs which only exist in either the HTML or CanvasKit renderers. | |
| In practice, this means these tests should only use `dart:ui` APIs or | |
| `dart:_engine` APIs which are not renderer-specific. | |
| ## Notes | |
| These tests should call `setUpUiTest()` at the top level to initialize the | |
| renderer they are expected to run. |
