# Defines an FHCP driver test.
# A test under the Fuchsia Hardware Compatibility Program is meant to be
# generic to the type of device under test. These tests are used to qualify
# a given driver as conforming to the standards of a Fuchsia driver.
#
# This template is equivalent to the `fuchsia_test_package` template, with
# a specific set of additions that enable FHCP metadata gathering. These
# additional parameters are all required so that FHCP tests are properly
# categorized.
#
# TODO(https://fxbug.dev/42059908): Link to further documentation about these parameters.
#
# Parameters
#
#   test_types (required)
#     The criteria type this test falls under. If the test evaluates that the driver has correct
#     functionality, then the value here should be `[ "functional" ]`. This is an array, so a test
#     can have multiple categories.
#     Type: array of strings
#   device_categories (required)
#     The types of devices that this test is intended to exercise. A device type consists of two
#     parts: an overarching type (such as "imaging") and a sub-type (such as "camera"). These are
#     paired up into braced ("{}") groups. A device can have multiple types, so this is an array
#     of those groups.
#     Example: [ {
#                  category = "input"
#                  subcategory = "touchpad"
#                },
#                {
#                  category = "bluetooth"
#                  subcategory = ""
#                } ]
#     Type: array of objects
#   test_specs.environments (required)
#     This is the same as `test_specs.environments` in fuchsia_test_package() but it is now
#     required. You must specify what type of Fuchsia devices(s) this driver test is able to
#     run on.
#     See //build/testing/environments.gni for some existing choices.
# See fuchsia_test_package() for additional parameters.
