# This is an internal Nix Flake intended for use when running tests.
#
# You can build all tests or specific tests by running
#
#   nix build --reference-lock-file flake.lock ./tests#test-all
#   nix build --reference-lock-file flake.lock ./tests#test-alacritty-empty-settings
#
# in the Home Manager project root directory.
#
# Similarly for integration tests
#
#   nix build --reference-lock-file flake.lock ./tests#integration-test-all
#   nix build --reference-lock-file flake.lock ./tests#integration-test-standalone-standard-basics
