使用ink3“self.env().block_timestamp()”的正确方法是什么

参考代码片段（完整代码为@https ://gist.github.com/shamb0/a1f24cd7981e169cc5b7d1e1b3ec4dd4）

        pub fn get_bts(&self) -> u64 {
            let bts = self.env().block_timestamp();
            bts
        }

在此函数上调用测试执行最终会在 'uninitialized execution context: UninitializedBlocks' 处出现恐慌错误。

注释必须是“#[ink::test]”而不是#[test]

        #[ink::test]
        fn bts_works() {
            let ink3_spad = Ink3Spad::new(false);
            assert_eq!(ink3_spad.get(), false);
            let dbg_fmtstr = format!("{:?}", ink3_spad.get_bts() );
            ink_env::debug_println( &dbg_fmtstr );
        }

感谢@LaurentTrk 为我指出解决方案...
