如何在typescript的单元测试中模拟类中的硬私有属性

class MyClass {
  private _privateProperty: string;

  public get privateProperty(): string {
    return this._privateProperty;
  }

  public set privateProperty(value: string) {
    this._privateProperty = value;
  }
}

// 单元测试中模拟私有属性的操作
const myObject = new MyClass();
myObject.privateProperty = 'mocked value';
console.log(myObject.privateProperty); // 输出: "mocked value"

class MyClass {
  private privateProperty: string;
}

// 单元测试中模拟私有属性的操作
const myObject = new MyClass();
(myObject as any).privateProperty = 'mocked value';
console.log((myObject as any).privateProperty); // 输出: "mocked value"

class MyClass {
  private privateProperty: string;
}

// 单元测试中模拟私有属性的操作
const myObject = new MyClass();
const privateProperty = Reflect.get(myObject, 'privateProperty');
Reflect.set(myObject, 'privateProperty', 'mocked value');
console.log(Reflect.get(myObject, 'privateProperty')); // 输出: "mocked value"
