  • Explanation: assertMacroExpansion is used for testing macro expansions. It should check that the expanded macro is itself valid.
  • Scope: Macro unit testing
  • Risk: Very low. It's possible some existing tests may now fail, but that means that the underlying expansion needs to be updated.
  • Original PR: assertMacroExpansion should assert if there are errors #1758

Invalid macro expansions should generate an assertion in
`assertMacroExpansion` rather than being ignored.
