<pre>clang/unittests/Tooling/StencilTest.cpp has a test "CatOfInvalidRangeFails"
that ends with this code:
Expected<std::string> Result = S->eval(StmtMatch->Result);
ASSERT_THAT_EXPECTED(Result, Failed<StringError>());
llvm::handleAllErrors(Result.takeError(), [](const llvm::StringError &E) {
EXPECT_THAT(E.getMessage(), AllOf(HasSubstr("selected range"),
HasSubstr("macro expansion")));
});
However, the EXPECT_THAT is never executed (replacing it with an assert
or llvm_unreachable does not fire).
ASSERT_THAT_EXPECTED calls TakeExpected, which calls takeError(), and you
can't call takeError() twice on an Expected<T>.
