Cannot mock property `name`

[Socolin]

Hello,

This give me the following error

const frameMock = TypeMoq.Mock.ofType<HTMLIFrameElement>();
frameMock.setup(x => x.id = TypeMoq.It.isAnyString()).verifiable();
frameMock.setup(x => x.name = TypeMoq.It.isAnyString()).verifiable();

TypeError: 'set' on proxy: trap returned falsish for property 'name'

I'm getting the same error if I don't setup this mock and I directly call

frameMock.object.name = 'abc';

It's working on any other properties like id, src etc.. but not name

Workaround:

export class FakeHTMLIFrame extends HTMLIFrameElement {
  static a = "not-null"; // Trick compiler to not throw error and skip `super()` call
  constructor() {
    if (FakeHTMLIFrame.a == null) {
      super();
    }
  }
}

TypeMoq.Mock.ofType<FakeHTMLIFrame>(FakeHTMLIFrame, TypeMoq.MockBehavior.Loose, true);
