Mock object methods

[FriedrichGretz]

Currently, it seems we cannot mock an object method. An attempt to write something like
mock(myObj.tryGet, (): null | Something => fakeReturn)
will result in an error:
ERROR TS2322: Type '(this: MyClass) => Something | null' is not assignable to type '() => Something | null'.
Of course, adding a parameter for the this in the lambda will not work and produce
ERROR TS2322: Type '(this: MyClass) => Something | null' is not assignable to type '(MyClass) => Something | null'.

Is it technically possible to add mocks of object methods to the framework?
Otherwise OOP is either prohibited or not testable in AS when using this framework.

A workaround is

test("class method mock", () => {
    const mockClass = new MockClass();
    mock<(self: MockClass) => i32>(changetype<(self: MockClass) => i32>(mockClass.method), (self: MockClass): i32 => {
      self.v = 100;
      return 1;
    });
    expect(mockClass.method()).equal(1);
    expect(mockClass.v).equal(100);
  });

We had the same problem and asked for help.. I think it would be goof if the documentation is extended for this case.

What we currently do if we use more OOP is actually interfacing a lot. Then it is fairly easy just create a mock implementation. So most of the time, we don't need the mock functionality in such cases.
