# add_qtmaildir_test(<name>) builds tests/test_<name>.cpp and registers it.
#
# resources.qrc is compiled into each test binary for the same reason the app
# compiles it rather than the static library: a qrc inside a .a registers from
# a global initialiser the linker then drops. Library code reads :/fonts/ when
# it builds the placeholder pane, so a test that never links the qrc would
# exercise only the missing-resource fallback and pass against a broken build.
#
# Every test runs under the OFFSCREEN platform, set here rather than left to
# whatever the invoking session happens to use. This is not tidiness: a test
# that renders needs deterministic geometry, and a real windowing system does
# not provide it.
#
# The case that forced it (item 52). theDescriptionSurvivesAModestPopupWidth
# sizes a line edit to 550px and asserts a description survives the popup that
# results. Under Wayland the compositor gave the popup a viewport of 1278x0: the
# zero height made the grab return a null pixmap, which is what failed, but the
# 1278 width is the worse half. Had the grab succeeded, the test would have
# measured a popup more than twice the width it claims to be testing and passed
# while proving nothing about the 550px case.
#
# So the platform is pinned for correctness, not to dodge a red result. `ctest`
# sets no QT_QPA_PLATFORM of its own, so without this the suite's verdict
# depends on how it was invoked: it passed for a developer exporting `offscreen`
# by hand and failed under `ctest` in the same tree, which cost one wrong
# diagnosis before the cause was found.
