//! Tests for access to the embedded frontend assets.
//! 对内嵌前端资源的访问的测试。
//!
//! 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。
