From 30dcc19d1f30fc203be460134c4578509cce704f Mon Sep 17 00:00:00 2001 From: John Ericson Date: Thu, 5 Oct 2023 12:12:18 -0400 Subject: Put functional tests in `tests/functional` I think it is bad for these reasons when `tests/` contains a mix of functional and integration tests - Concepts is harder to understand, the documentation makes a good unit vs functional vs integration distinction, but when the integration tests are just two subdirs within `tests/` this is not clear. - Source filtering in the `flake.nix` is more complex. We need to filter out some of the dirs from `tests/`, rather than simply pick the dirs we want and take all of them. This is a good sign the structure of what we are trying to do is not matching the structure of the files. With this change we have a clean: ```shell-session $ git show 'HEAD:tests' tree HEAD:tests functional/ installer/ nixos/ ``` (cherry picked from commit 68c81c737571794f7246db53fb4774e94fcf4b7e) --- tests/functional/config.sh | 58 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 tests/functional/config.sh (limited to 'tests/functional/config.sh') diff --git a/tests/functional/config.sh b/tests/functional/config.sh new file mode 100644 index 000000000..723f575ed --- /dev/null +++ b/tests/functional/config.sh @@ -0,0 +1,58 @@ +source common.sh + +# Isolate the home for this test. +# Other tests (e.g. flake registry tests) could be writing to $HOME in parallel. +export HOME=$TEST_ROOT/userhome + +# Test that using XDG_CONFIG_HOME works +# Assert the config folder didn't exist initially. +[ ! -e "$HOME/.config" ] +# Without XDG_CONFIG_HOME, creates $HOME/.config +unset XDG_CONFIG_HOME +# Run against the nix registry to create the config dir +# (Tip: this relies on removing non-existent entries being a no-op!) +nix registry remove userhome-without-xdg +# Verifies it created it +[ -e "$HOME/.config" ] +# Remove the directory it created +rm -rf "$HOME/.config" +# Run the same test, but with XDG_CONFIG_HOME +export XDG_CONFIG_HOME=$TEST_ROOT/confighome +# Assert the XDG_CONFIG_HOME/nix path does not exist yet. +[ ! -e "$TEST_ROOT/confighome/nix" ] +nix registry remove userhome-with-xdg +# Verifies the confighome path has been created +[ -e "$TEST_ROOT/confighome/nix" ] +# Assert the .config folder hasn't been created. +[ ! -e "$HOME/.config" ] + +# Test that files are loaded from XDG by default +export XDG_CONFIG_HOME=$TEST_ROOT/confighome +export XDG_CONFIG_DIRS=$TEST_ROOT/dir1:$TEST_ROOT/dir2 +files=$(nix-build --verbose --version | grep "User config" | cut -d ':' -f2- | xargs) +[[ $files == "$TEST_ROOT/confighome/nix/nix.conf:$TEST_ROOT/dir1/nix/nix.conf:$TEST_ROOT/dir2/nix/nix.conf" ]] + +# Test that setting NIX_USER_CONF_FILES overrides all the default user config files +export NIX_USER_CONF_FILES=$TEST_ROOT/file1.conf:$TEST_ROOT/file2.conf +files=$(nix-build --verbose --version | grep "User config" | cut -d ':' -f2- | xargs) +[[ $files == "$TEST_ROOT/file1.conf:$TEST_ROOT/file2.conf" ]] + +# Test that it's possible to load the config from a custom location +here=$(readlink -f "$(dirname "${BASH_SOURCE[0]}")") +export NIX_USER_CONF_FILES=$here/config/nix-with-substituters.conf +var=$(nix show-config | grep '^substituters =' | cut -d '=' -f 2 | xargs) +[[ $var == https://example.com ]] + +# Test that it's possible to load config from the environment +prev=$(nix show-config | grep '^cores' | cut -d '=' -f 2 | xargs) +export NIX_CONFIG="cores = 4242"$'\n'"experimental-features = nix-command flakes" +exp_cores=$(nix show-config | grep '^cores' | cut -d '=' -f 2 | xargs) +exp_features=$(nix show-config | grep '^experimental-features' | cut -d '=' -f 2 | xargs) +[[ $prev != $exp_cores ]] +[[ $exp_cores == "4242" ]] +[[ $exp_features == "flakes nix-command" ]] + +# Test that it's possible to retrieve a single setting's value +val=$(nix show-config | grep '^warn-dirty' | cut -d '=' -f 2 | xargs) +val2=$(nix show-config warn-dirty) +[[ $val == $val2 ]] -- cgit v1.2.3
