问题描述
这个主题有一个过去的问题，但未发布答案:
There is a past question on this topic, but no answer was posted:
我想为testdouble-jest创建类型，但是其导出函数中的第二个参数是全局jest实例，该实例在@types/jest中声明为顶级声明的命名空间:
I want to make a type for testdouble-jest, but the second argument in its exported function is the global jest instance, which is declared in @types/jest as a top-level declared namespace:
declare namespace jest {
mock(): something
// ...
}
以下是这些类型: https: //github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/jest/index.d.ts
如何在test-double.d.ts声明中引用此全局对象?我的声明如下，但部分成功:
How can I refer to this global object in my test-double.d.ts declaration? My declaration looks as follows, but with partial success:
/// <reference types="jest" />
// do i actually need the above directive?
declare module "testdouble-jest" {
import * as td from "testdouble"; // the testdouble stuff works
export type TestdoubleJest = typeof td & {
mock: typeof jest.mock; // this actually appears to work
};
function setupTestdoubleJest(
testdouble: typeof td,
jest: typeof jest // this just resolves to any
): TestdoubleJest;
export = setupTestdoubleJest;
}
如果有人知道该怎么做，我将不胜感激！
If anyone knows how to do this, I would really appreciate it!
编辑２:有一些关于DefinitelyTyped的人的例子，它们要么增加了'jest'名称空间，要么使用了它的成员(就像我对jest.mock所做的那样)，但是我找不到一个引用实际全局jest对象.
EDIT ２： There are some examples on DefinitelyTyped of people either augmenting the ‘jest‘ namespace or using its members (like I did with jest.mock), but I can't find one referring to the actual global jest object.
推荐答案
替换
/// <reference types="jest" />
使用
/// <reference types="@types/jest" />
对我有用.
