在 Rust 中运行集成测试时如何查看日志记录（特别是使用 NEAR Workspaces-rs）

我在用着https://github.com/near/workspaces-rs/ https://github.com/near/workspaces-rs/我的函数中有一些行，例如log!("Removed {} from {}", &key, &recipient);

(using use near_sdk::{env, log};)

但是当我运行集成测试时，这些日志消息不会出现在终端中。

如何初始化集成测试的记录器？ https://stackoverflow.com/questions/30177845/how-to-initialize-the-logger-for-integration-tests#comment129424339_55268274向我指出https://docs.rs/env_logger/0.9.0/env_logger/index.html#capturing-logs-in-tests https://docs.rs/env_logger/0.9.0/env_logger/index.html#capturing-logs-in-tests这给出了这个例子：

#[cfg(test)]
mod tests {
    fn init() {
        let _ = env_logger::builder().is_test(true).try_init();
    }

    #[test]
    fn it_works() {
        init();

        info!("This record will be captured by `cargo test`");

        assert_eq!(2, 1 + 1);
    }
}

但即使我创建并调用它init()功能并取代我的log!()打电话给info!()，我什么也没得到。

（我可以看到测试本身的日志输出，但看不到主实现代码中的日志记录。）

日志将显示在结果中.call()并且可以从receipts返回的数据结构中的元素（receipts -> ExecutionOutcome -> logs).

为了证明这是有效的，我在项目目录中创建了一个新项目npx create-near-app它带有 TypeScript 中的基本 get-set 字符串约定。我删除了integration-tests文件夹，因为实现是在 JS/TS 中，并在其中创建了一个新的测试文件夹，其结构与此处看到的类似：https://github.com/near-examples/NFT/tree/master/integration-tests/rs https://github.com/near-examples/NFT/tree/master/integration-tests/rs

以下是我修改的文件：https://gist.github.com/idea404/5ecbcfaa2b1e41b9e33df15dfdaa0dae https://gist.github.com/idea404/5ecbcfaa2b1e41b9e33df15dfdaa0dae

运行测试后npm test从项目的根目录，我得到以下输出：
