Typescript和Jest:mocking抛出TypeError，因为它使用了错误的重载

在一个玩笑测试中给出以下内容

const mockDirListing:string[]=['sdafd'，'sfdf']；
const mockReaddirSync=jest.spyOn（fs，'readdirSync'）；
mockReaddirSync.mockReturnValue（mockDirListing）；

TypeScript将出现以下错误：

Argument of type 'string[]' is not assignable to parameter of type 'Dirent[]'.
Type 'string' is not assignable to type 'Dirent'.ts(2345)

模拟实例的类型为

jest.SpyInstance<fs.Dirent[], [fs.PathLike, {
    encoding?: string;
    withFileTypes: true;
}]>

投掷

Argument of type '(a: string) => string' is not assignable to parameter of type '(a: number) => string'.
  Types of parameters 'a' and 'a' are incompatible.
    Type 'number' is not assignable to type 'string'.ts(2345)

如何使用第一个重载的类型签名？

我们将在研究它之后，看起来您能做的最好的事情是

const stub = (sinon.stub(fs, 'readdir') as unknown) as sinon.SinonStub<any[], Promise<Dirent[]>>;

const stub=（sinon.stub（fs，'readdir'）为未知）为sinon.SinonStub；

一旦指定，将类型强制为

Argument of type '(a: string) => string' is not assignable to parameter of type '(a: number) => string'.
  Types of parameters 'a' and 'a' are incompatible.
    Type 'number' is not assignable to type 'string'.ts(2345)

const stub = (sinon.stub(fs, 'readdir') as unknown) as sinon.SinonStub<any[], Promise<Dirent[]>>;
