Can we add a line/comment to explain what this test does? Same for the input files.

Well all the 'Import/<node-name>' tests just try importing the respective AST node type and run checks on the node after importing. But we probably should reorganize the test/Import folder in the future, so then we can better document that the tests in the respective 'node-types` folder or so are supposed to do just this kind of check.

test/Import/cxx-noexcept-expr/Inputs/F.cpp

+bool f() { return noexcept(1); }

test/Import/cxx-noexcept-expr/test.cpp

+// RUN: clang-import-test -dump-ast -import %S/Inputs/F.cpp -expression %s | FileCheck %s
+
+// CHECK: CXXNoexceptExpr
+// CHECK-NEXT: IntegerLiteral
+
+void expr() {
+  f();
+}
