#!/usr/bin/env bats
# -----------------------------------------------------------------------------
# Unit tests for hack/select-e2e.sh
#
# cozytest.sh's awk parser recognizes only @test blocks and a bare `}` on its
# own line; there is no bats `run` or `$status`. Each test runs as a shell
# function under `set -eu -x`, so assertions are direct shell tests that exit
# non-zero on failure. setup()/teardown() are not honored — each test creates
# and cleans its own scratch dir.
#
# Run with: hack/cozytest.sh hack/select-e2e_test.bats
# -----------------------------------------------------------------------------
