Angular Karma Writing unit tests for get method_name returns 'method

My ts code is as follows,

 private _state: State = {
    page: 1,
    pageSize: 4,
    searchTerm: '',
    sortColumn: '',
    sortDirection: ''
  };
      get page() { return this._state.page; }
      get pageSize() { return this._state.pageSize; }
      get searchTerm() { return this._state.searchTerm; }

When I wrote the tests,

it('searchTerm()', () => {
        (component as any)._state = {
            page: 1,
            pageSize: 4,
            searchTerm: '',
            sortColumn: '',
            sortDirection: ''
          };
        let result = (component as any).searchTerm();
        expect(result).toEqual('');
    });

It returns the below error, Chrome 101.0.4951.67 (Windows 10) NgbdTableComplete searchTerm() FAILED TypeError: component.searchTerm is not a function at UserContext.

CodePudding user response：

It seems like that should be accessed like an actual property, without the parentheses (). You can find more info about such getters here.
