Is this different from just setting doCheck = false;?

[milahu]

yes, ideally ...

this was just a quick-and-dirty patch to disable tests
some parts of checkPhase are required for nix run . and i did not know where to move them

nix-gui/flake.nix

Lines 82 to 98 in 4ed1e06

	checkPhase = let
	sample = "${./nixui/tests/sample}";
	in ''
	export QT_QPA_PLATFORM=offscreen
	export QT_PLUGIN_PATH="${pkgs.qt5.qtbase}/${pkgs.qt5.qtbase.qtPluginPrefix}"
	export XDG_RUNTIME_DIR=$NIX_BUILD_TOP
	export HOME=$NIX_BUILD_TOP
	export NIX_STATE_DIR=$NIX_BUILD_TOP
	export NIX_PATH=${pkgs.path}:nixpkgs=${pkgs.path}:nixos-config=${sample}/configuration.nix
	cd nixui
	'' + (if runTests then ((if !enable-profiling then ''
	python3 -m pytest -vv ${specific-test}
	'' else ''
	python3 -m cProfile -o profile -m pytest ${specific-test}
	python3 -c "import pstats; p = pstats.Stats('profile'); p.strip_dirs(); p.sort_stats('cumtime'); p.print_stats(50)"
	'')) else "");

the qt variables should be set via wrapQtAppsHook

IMO we should fix Qt environment variables instead of merging this.
