This guide provides instructions on how to run an end-to-end test for testing a Fuchsia product.
screen_is_not_black_no_basemgr_test end-to-end test reboots a device under test
(DUT), waits 100 seconds, and takes a snapshot of the device’s screen. If the
snapshot image is not a black screen, the test concludes that Fuchsia is
successfully up and running on the device after reboot.
To run this end-to-end test, the steps are:
- Build a Fuchsia image to include the end-to-end test.
- Start the emulator with the Fuchsia image.
- Run the end-to-end test.
Verify the following requirements:
Build a Fuchsia image to include the end-to-end test
Before you can run the
screen_is_not_black_no_basemgr_test end-to-end test, you first
need to build your Fuchsia image to include the test in the build artifacts:
To add the end-to-end test, run the
fx setcommand with the following
fx set workstation.x64 --with //src/tests/end_to_end/screen_is_not_black:no_basemgr_test
//src/tests/end_to_end/screen_is_not_blackis a test directory in the Fuchsia source tree. The
BUILD.gnfile in this directory defines the
testtarget to include the
screen_is_not_black_no_basemgr_testend-to-end test in the build artifacts.
Build your Fuchsia image:
fx buildcommand completes, the build artifacts now include the
screen_is_not_black_no_basemgr_testend-to-end test, which you can run from your host machine.
Start the emulator with the Fuchsia image
Start the emulator with your Fuchsia image and run a package repository server:
Configure an IPv6 network for the emulator (you only need to do this once):
sudo ip tuntap add dev qemu mode tap user $USER && sudo ifconfig qemu up
In a new terminal, start the emulator:
fx emu -N
Set the emulator to be your device:
If you have multiple devices, select
step-atom-yard-juicy(the emulator’s default device name), for example:
$ fx set-device Multiple devices found, please pick one from the list: 1) rabid-snort-wired-tutu 2) step-atom-yard-juicy #? 2 New default device: step-atom-yard-juicy
In another new terminal, start a package repository server:
fx servecommand running as a package server for your device.
Run the end-to-end test
screen_is_not_black_no_basemgr_test end-to-end test:
fx run-e2e-tests screen_is_not_black_no_basemgr_test
When the test passes, this
fx command prints the following output in the end:
Saw a screen that is not black. [FINE]: Running over ssh: killall sl4f.cmx 01:04 +1: All tests passed! 1 of 1 test passed
Run any end-to-end test
fx run-e2e-tests command to run an end-to-end test from your host
fx run-e2e-tests <TEST_NAME>
Some product configurations may include a set of end-to-end tests by default. However, if you want to run an end-to-end test that is not part of your product configuration, configure and build your Fuchsia image to include the specific test:
fx set PRODUCT.BOARD --with TEST_DIRECTORY:TARGET
For example, the following command configures your Fuchsia image to include all
the end-to-end tests in the
fx set workstation.qemu-x64 --with //src/tests/end_to_end/perf:test
For the list of all available end-to-end tests in the Fuchsia repository, see the //src/tests/end_to_end directory.
