      icon:'pi pi-fw pi-pencil',
      command: e => this.viewApplicantWithdraw(this.selectedGridMenuItem.reqTpsReferenceId),
      disabled: this.sharedService.isMspUser(),
     },

     {
      label:'History',
      icon:'pi pi-eye',
      command: e => this.getRequisitionSubmissionStatusHistoryById(this.selectedGridMenuItem.submissionId),
     }

  ];        

Answer 1

I got the answer ...

        let viewApplicantWithdrawspy= jest.spyOn(ApplicantSubmissionSearchComponent.prototype as any, 'viewApplicantWithdraw').mockReturnValue(true);
    let getRequisitionSubmissionStatusHistoryByIdspy= jest.spyOn(ApplicantSubmissionSearchComponent.prototype as any, 'getRequisitionSubmissionStatusHistoryById').mockReturnValue(true);
    this.selectedGridMenuItem={reqTpsReferenceId:1,submissionId:2,appTpsReferenceId: 3, submissionReferenceId: 4,applicantId:5,companyId:6}
    let isMspUserSpy = jest.spyOn(sharedServiceMock, 'isMspUser').mockReturnValue(true);

    this.itemsWithdrawMock = [
      {
        label:'Withdraw Applicant',
        icon:'pi pi-fw pi-pencil',
        command: jest.fn((event?: any) => {}),
        disabled: isMspUserSpy
       },

       {
        label:'History',
        icon:'pi pi-eye',
        command: jest.fn((event?: any) => {})
       }

    ];
    this.itemsWithdraw[0].command();
    this.itemsWithdraw[1].command();
  expect(viewApplicantWithdrawspy).toHaveBeenCalledWith(1);
  expect(getRequisitionSubmissionStatusHistoryByIdspy).toHaveBeenCalledWith(2)
      expect(isMspUserSpy).toBeCalled();
