//! Tests for the response writer.

//! 响应写出器的测试。

//! They live here rather than inside the module so that `src/` holds no test
|
||
//! code, as it does in `apsis-rs`. An integration test is a separate crate and
|
||
//! reaches only what the library makes public, so the few internal items the
|
||
//! tests need are opened through `apsis_book::testkit`.
|
||
|
||
//!
|
||
//! 它们放在这里而不是模块内部，使 `src/` 不含测试代码，与 `apsis-rs` 一致。
|
||
//! 集成测试是独立的 crate，只能触达库公开的部分，因此测试所需的那少数内部条目
|
||
//! 经 `apsis_book::testkit` 开放。
