# =============================================================
# OxiCloud — invite-by-email + magic-link redemption (PR 9)
# =============================================================
# End-to-end: Alice shares a folder with bob@externalcompany.com,
# the server lazily provisions bob as an external user, sends the
# invitation through MockEmailSender, and bob redeems the magic
# link to land authenticated on the resource.
#
# Requires `OXICLOUD_SMTP_MOCK=true` in tests/common/server.env so
# the in-process capture endpoint at /api/admin/smtp/test/captured
# is mounted. The .hurl file would error on a real SMTP setup
# because the magic link wouldn't be retrievable.
