Sinon 创建 stub 实例 - 包括 protected 属性

Question

我的问题是如何在创建 stub 实例时包含 protected 属性。

在我的笑话测试中我有:

const sandbox = createSandbox();
let manager: SinonStubbedInstance<EntityManager>;
let repo: Repo;

beforeEach(() => {
    manager = sandbox.createStubInstance(EntityManager);
    repo = new Repo(manager);
});

afterEach(() => sandbox.restore());

正在尝试制作 stub :

export declare class EntityManager {

/**
 * Connection used by this entity manager.
 */
readonly connection: Connection;

/**
 * Custom query runner to be used for operations in this entity manager.
 * Used only in non-global entity manager.
 */
readonly queryRunner?: QueryRunner;

/**
 * Once created and then reused by en repositories.
 */
protected repositories: Repository<any>[];

/**
 * Plain to object transformer used in create and merge operations.
 */
.......
}

所以我似乎无法在 stub 中包含只读属性和 protected 属性。

在“repo = new Repo(manager);”线。上面的代码会产生以下异常:

Argument of type 'SinonStubbedInstance<EntityManager>' is not assignable to parameter of type 'EntityManager'.
Property 'repositories' is missing in type 'SinonStubbedInstance<EntityManager>'.ts(2345)

有没有办法告诉诗乃包含这些属性？任何帮助将不胜感激。
