# Declares an in-tree Python E2E Mobly test for distribution in the SDK.
#
# Example:
# ```
# python_mobly_test("my-test") {
#   main_source = "main.py"
#   testonly = false  # Required for SDK inclusion.
# }
#
# sdk_python_mobly_test("my-sdk-test") {
#   sdk_name = "my-test"
#   test_label = ":my-test"
#   category = "partner"
# }
# ```
#
# Parameters
#
#   test_label
#     The Python E2E test to distribute. Must point to a python_mobly_test()
#     target.
#     Type: label.
#
#   sdk_name
#     Name of the test in the SDK.
#     Type: string.
#
#   category
#     Publication level of the library in SDKs.
#     See //build/sdk/sdk_atom.gni for more.
#     Type: string.
#
#   sdk_area (optional)
#     [string] The API area responsible for maintaining this library.
#     See //build/sdk/sdk_atom.gni.
