typeHelloWorld=any;// you should make this worktypetest=Expect<Equal<HelloWorld,string>>; 这里稍微提一下,Expect和Equal是 type-challenges 提供的辅助类型,用于测试类型是否正确。你就暂且当作 jest 里的expect和toEqual吧。只不过这里的Expect和Equal是用来比较类型(抽象)的;而 jest 的expect和toEqual是通常用于...

社区解决方案在 Typroof 诞生之前，社区主要依赖两种方法进行类型测试。一种是编写工具类型，如 Expect 和 Equal，利用这些类型实现简单的断言。另一种是使用 tsd，通过编写以 .test-d.ts 结尾的文件，执行静态代码分析以检查类型是否符合预期。虽然这两种方法各有优缺点，但 Typroof 旨在整合这些解决方案...
expect(manager.books.length).to.equal(0); }); }); }); 在package.json中添加一个test脚本: "scripts": { "test": "mocha --compilers ts:ts-node/register test/**/*.ts" } 运行测试: npm run test 如果一切正常,测试将成功通过。
