// Verifies that the Info.plist content matches the expected scheme
// configuration determined by the C++ logic.
//
// Mac Info.plist is generated at build time (by
// build/apple/tweak_info_plist.py), whereas runtime checks (like
// IsDefaultClientForScheme) rely on C++ logic in shell_integration_mac.mm.
//
// This test ensures these two separate implementations remain in sync for the
// build configuration under test (typically Stable or Chromium).
//
// Note: Logic for removing the scheme for non-stable channels (Beta/Dev/Canary)
// happens during signing (chrome/installer/mac/signing/modification.py) and is
// verified by python unit tests
// (chrome/installer/mac/signing/modification_test.py), as this browser test
// cannot easily run against signed/channel-customized builds.
// TODO(crbuig.com/446672134): Fix and re-enable.
