   generally speaking, `cargo test` collects all `#[test]`s and creates a binary with a fixed driver and `libtest`. we don't have chance to change the compiler ad `libtest`. so the only chance to use `cargo test` is to test the untrusted app, not the enclave.
   
   good news is that we can use [inventory](https://github.com/mesalock-linux/inventory-sgx) and a proc-macro to implement something very similar to `#[test]` which collect every test fn pointer (decorated by the customized proc macro attribute) into a static array and then drive these test fn ptrs with our own prebuilt driver. in this way, though we cannot use `#[test]`, we can construct an only with all test `fn`s automatically, and export only 1 ECALL fn for triggering the tests.
