“Ensuring Exception Safety Through Testing"
summary
Describes a concrete testing system that uses a global counter to deterministically throw the nth exception, an error-tracker to catch internally handled throws, and configurable fakes like the maybe_throw macro and throwing value fake; tests run each injected failure against per-operation contracts, use factories to support move-only types, and run under ASan/LSan to catch UB and leaks. The tooling finds real bugs in Abseil and in standard-library implementations, and the implementation lives in Abseil internals with a planned merge into Googletest.
