This isn't guaranteed to run long enough to get foo() to tier up.  It'll wait for test() to tier up.  Normally, our heuristics will compile foo() before test() because foo() is smaller and is called more frequently, but we shouldn't be relying on heuristics in the tests.  You can fix this by saying:

dfgShouldBe(foo, "test()", "9");
