+# mouse-input
+
+`mouse-input-test` exercises mouse input through a child view (in this case, the `mouse-input-view` Dart component) and 
+asserting the location as well as what button was used (mouse down, mouse up, wheel, etc) during the event. We do this by 
+attaching the child view, injecting mouse input, and validating that the view reports the event back with the expected 
+payload.
+
+```shell

+## Running the Test
+
+Reference the Flutter integration test [documentation](https://github.com/flutter/engine/blob/main/shell/platform/fuchsia/flutter/tests/integration/README.md) at `//flutter/shell/platform/fuchsia/flutter/tests/integration/README.md`
+
+## Playing around with `mouse-input-view`
+
+Build Fuchsia with `workstation_eng.qemu-x64`
+```shell
+fx set workstation_eng.qemu-x64 && fx build
+```
+
+Build flutter/engine
+```shell
+$ENGINE_DIR/flutter/tools/gn --fuchsia --no-lto && ninja -C $ENGINE_DIR/out/fuchsia_debug_x64 flutter/shell/platform/fuchsia/flutter/tests/
+integration/mouse_input:tests
+```
+
+Start a Fuchsia package server
+```shell
+cd "$FUCHSIA_DIR"
+fx serve
+```
+
+Publish `touch-input-view`
+```shell
+$FUCHSIA_DIR/.jiri_root/bin/fx pm publish -a -repo $FUCHSIA_DIR/$(cat $FUCHSIA_DIR/.fx-build-dir)/amber-files -f $ENGINE_DIR/out/
+fuchsia_debug_x64/gen/flutter/shell/platform/fuchsia/flutter/tests/integration/mouse-input/mouse-input-view/mouse-input-view/mouse-input-view.far
+```
+
+Launch Fuchsia emulator in a graphical environment
+```shell
+ffx emu start
+```
+
+**Before proceeding, make sure you have successfully completed the "Set a Password" screen**
+
+Add `mouse-input-view`
+```shell
+ffx session add fuchsia-pkg://fuchsia.com/mouse-input-view#meta/mouse-input-view.cm
+```
