+# `surfaceflinger_end2end_tests`
+
+Tests to cover end to end testing of SurfaceFlinger.
+
+In particular the test framework allows you to simulate various display
+configurations, so the test can confirm displays are handled correctly.
+
+## Quick Useful info
+
+### Running the tests
+
+At present the tests should run on any target, though the typical target would
+be a [Cuttlefish](https://source.android.com/docs/devices/cuttlefish) VM
+target such as `aosp_cf_x86_64_phone`.
+
+At some future time the test may be rewritten to require
+[`vkms`](https://dri.freedesktop.org/docs/drm/gpu/vkms.html) and
+[`drm_hwcomposer`](https://gitlab.freedesktop.org/drm-hwcomposer/drm-hwcomposer)
+
+```
+atest surfaceflinger_end2end_tests
+```
+
+You can also run the google test binary directly. However you will also need
+to run a few other set-up and tear-down commands that are part of the
+AndroidTest.xml configuration, so that SurfaceFlinger can be used run isolation
+from the rest of the system.
+
+```
+# Set-up
+adb root
+adb shell stop
+adb shell setenforce 0
+adb shell setprop debug.sf.nobootanimation 1
+
+# Sync and run the test
+adb sync data
+adb shell data/nativetest64/surfaceflinger_end2end_tests/surfaceflinger_end2end_tests
+
+# Tear-down
+adb shell stop
+adb shell setenforce 1
+adb shell setprop debug.sf.nobootanimation 0
+adb shell setprop debug.sf.hwc_service_name default
+```
+
+### Manual clang-tidy checks via Soong
+
+At present Android does not run the clang-tidy checks as part of its
+presubmit checks.
+
+You can run them through the build system by using phony target that are
+automatically created for each source subdirectory.
+
+For the code under `frameworks/native/services/surfaceflinger/tests/end2end`,
+you would build:
+
+```
+m tidy-frameworks-native-services-surfaceflinger-tests-end2end
+```
+
+For more information see the build documentation:
+
+* <https://android.googlesource.com/platform/build/soong/+/main/docs/tidy.md#the-tidy_directory-targets>
+
+### Seeing clang-tidy checks in your editor
+
+If your editor supports using [`clangd`](https://clangd.llvm.org/) as a
+C++ language server, you can build and export a compilation database using
+Soong. With the local `.clangd` configuration file, you should see the same
+checks in editor, along with all the other checks `clangd` runs.
+
+See the build documentation for the compilation database instructions:
+
+https://android.googlesource.com/platform/build/soong/+/main/docs/compdb.md
