javascript - protractor js e2e tests, using multiple conditions on expect -

-

in current test i'm working on, need validate individual column on individual row, , check value accordingly, think expect(...) i'm getting wrong i'm not entirely sure, errors i'm getting are:

typeerror: object [object object] has no method 'row'
typeerror: cannot call method 'element' of undefined

//function in page.js file:  page.prototype.getsummaryinfo = function () {     return element.all(by.repeater('accountssummary in accountssummaries'))         .map(function (item, idx, rownumber) {              return {                   index: idx,                   row: rownumber.element(by.repeater('accountssummary in accountssummaries')).get(rownumber),                   currency: item.element(by.binding('accountssummary.currency')).gettext(),                   totalbalance: item.element(by.binding('accountssummary.amount')).gettext(),                   totalaccounts: item.element(by.binding('accountssummary.noofaccounts')).gettext()              };         }); };  // calling function in test:  it("should summary info", function() {   var details =  page.getsummaryinfo();   expect(details.row(2)).totalaccounts.tobe("17");      });
