# Builds test fixtures for a unit test.
#
# Generates a directory structure containing an assets directory and the Dart
# code to execute compiled to kernel. Generates:
# * an asserts directory at `$target_name/assets`.
# * a C++ implementation for `flutter/testing/testing.h`, defining
# `testing::GetFixturesPath()`, which returns the assets path.
# * a kernel snapshot at `$target_name/assets/$kernel_out`.
#
# Rule attributes:
# * fixtures: list of Dart files, including a main entrypoint.
# * kernel_out: the output path, relative to the assets directory, of the
# generated kernel snapshot. By default, `kernel_blob.bin`.
