# Tests for aw_autostart.sh — ActivityWatch's autostart wiring and self-checks.
#
# The subject writes an XDG .desktop entry, appends an `exec` line to the i3
# config, and generates an i3blocks status script. All of it lands under
# $USER_HOME, which the suite points at a throwaway dir -- so unlike its
# siblings this one does not need root paths. It still runs under the jail
# with the rest of the directory's suites; see jail_args beside this file.
#
# The generated i3blocks script is asserted by EXECUTING it against stubbed
# pacman/pgrep, not by grepping its text: "AW on" vs "AW off" is the thing
# that reaches the status bar, and a heredoc that emits syntactically broken
# bash would pass a text check and fail in front of the user.
