How to test an anonymous function written inside super method in Angular

Let's visit this code:

export class Child extends Base
{
   constructor(){
      super();
      this.getSomething();
   }
   getSomething(){

     super.setValue(**(value)=>{

      return value,
     })**
    }
}

How to cover the test coverage for the code written between **?

I wrote this much code but is not covering the code written between **.

import { Child } from "./Child";


describe("Child", () => {

  it("should create an instance", () 开发者_如何学Go=> {
    expect(new Child()).toBeTruthy();
  });
});
