  • this is useless, we need the code you test, and the actual test... we can't help if you paste here the error message only... – oma Sep 10 '19 at 13:45
  • please check below code written in component.ts – Jagadish M Sep 11 '19 at 12:05
  • public referralCheck() { this.loginService.getUserInfo().then(userInfo => { if (userInfo.securityGroups.includes('CMCP_REFERRAL')) { this.isReferral = true; } else { this.isReferral = false; } }); } – Jagadish M Sep 11 '19 at 12:05
  • below test case written in spec file – Jagadish M Sep 11 '19 at 12:05
  • it('should check referralCheck', () => { const spyTest = spyOn(logservice, 'getUserInfo').and.returnValue(when(usermockData)); component.referralCheck(); expect(spyTest).toHaveBeenCalled(); }); – Jagadish M Sep 11 '19 at 12:06
  • where usermockData is declared as "const usermockData = {securityGroups: '01UREG1_CMCP_ENQUIRY'};" – Jagadish M Sep 11 '19 at 12:06
