# Device Configuration for localization_rendering_tests #

## Setup ##
Include the following three files in a new directory that you would want to run
your test from. These files would be referred to as the configuration files.
* Android.bp
* TEST_MAPPING
* test_main.cpp


## Android.bp file ##
Define a new module in the Android.bp file.

The following is a template for the Android.bp file, only the <device name> needs to be replaced.

cc_test_host {
    name: "system.teeui_localization_rendering_test.<device name>",
    cflags: [
        "-Wall",
        "-Werror",
        "-Wextra",
        "-O0",
    ],
    srcs: [
        "test_main.cpp",
    ],
    test_suites: ["device-tests"],
    shared_libs: [
        "libbase",
        "libteeui_localization_rendering_test",
    ],
    static_libs: [
        "libgtest",
    ]
}


## TEST_MAPPING ##
The TEST_MAPPING file is going to run the test as a postsubmit test with the
configuration parameters set within this file.

The following is a template for the TEST_MAPPING file. All the flags should be
configured with the values specific to the device. If no configuration is
provided, the values will default to the values for Blueline.

{
  "postsubmit": [
    {
      "name": "system.teeui_localization_rendering_test.<device name>",
      "host" : true,
      "options": [
          {
            "native-test-flag": "--width=<device width in pixels>"
          },
          {
            "native-test-flag": "--height=<device height in pixels>"
          },
          {
            "native-test-flag": "--dp2px=<pixel per density independent pixel (px/dp) ratio of the device. Typically <width in pixels>/412 >"
          },
          {
            "native-test-flag": "--mm2px=<pixel per millimeter (px/mm) ratio>"
          },
          {
            "native-test-flag": "--powerButtonTop=<distance from the top of the power button to the top of the screen in mm>"
          },
          {
            "native-test-flag": "--powerButtonBottom=<distance from the bottom of the power button to the top of the screen in mm>"
          },
          {
            "native-test-flag": "--volUpButtonTop=<distance from the top of the UP volume button to the top of the screen in mm>"
          },
          {
            "native-test-flag": "--volUpButtonBottom=<distance from the bottom of the UP power button to the top of the screen in mm>"
          },
          {
             "native-test-flag": "--saveScreen"
          }
        ]
    }
  ]
}

## test_main.cpp ##
The current directory contains a test_main.cpp that initiates the localization
rendering test.
Make a copy of the cpp file (found in this directory) and place it in the
test configuration directory you will run the test from.

## Run test ##
To run the tests against the TEST_MAPPING configurations use the following
command:
	atest --test-mapping [src_path]:all
more info on how to run atest can be found here: https://source.android.com/compatibility/tests/development/test-mapping

It is possible to run the test as a binary and pass in configuration
values as commandline parameters.
The following command is how to run the test
in the commandline.
	atest system.teeui_localization_rendering_test.<device name> -- \

	com.android.tradefed.testtype.HostGTest:native-test-flag:"--width=100"\
