什么是使用ink3的正确方法？ self.envblock_timestamp|测试错误::'未初始化的执行上下文：UninitializedBlocks'

问题描述

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

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

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

对此功能调用测试执行会导致错误在“未初始化的执行上下文：UninitializedBlocks”中惊恐。

解决方法

注释必须为“＃[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 );
        }
