         <td class="ng-binding">Vinh</td>
         <td class="ng-binding">J.</td>
         <td class="ng-binding">F</td>

      </tr>

     <tr ng-repeat="listItem in filteredListItems | orderBy:predicate:reverse" ng-class="rowClass(listItem)" class="ng-scope">
         <td class="ng-binding">12</td>
         <td class="ng-binding">Tam12</td>
         <td class="ng-binding">Mr.</td>
         <td class="ng-binding">Steve</td>
         <td class="ng-binding">John</td>
         <td class="ng-binding">A.</td>
         <td class="ng-binding">F</td>
         <td class="ng-binding"></td>
         <td><a ng-href="#/detailView/patients/12" href="#/detailView/patients/12">Details</a></td>
         <td><button ng-click="deleteRecord(12)" class="btn btn-danger btn-xs"><span class="glyphicon glyphicon-remove"></span> Delete</button></td>
      </tr>
   </tbody>
</table>

I tried like this, but it's not working.

it('Patient Page text testing', function(){

        var table = element(by.css('.table'));
    var firsttag = table.element(by.tagName('tbody'));
    var secondtag = firsttag.all(by.tagName('tr')).get(0);
    var thirdtag = secondtag.all(by.tagName('th')).get(0);        
     expect(element(by.xpath('//b/a')).getText()).toEqual('Patient Id');
    var thirdtag = secondtag.all(by.tagName('th')).get(1);        
     expect(element(by.xpath('//b/a')).getText()).toEqual('Account Number');
});

In the above test, expectation is working but second expectation is not working.

Error :

Message:
 Expected 'Patient Id' to equal 'Account Number'.

Still in the second expectation it is expecting 'Patient Id'. I don't no where I did wrong.

Instead, find all headers using element.all() and use map() to assert the list in one go:

var headers = element.all(by.css('table.table th a')).map(function(elm) {
    return elm.getText();
});

expect(headers).toEqual([
    "Patient Id",
    "Account Number",
    "Title",
    "First Name",
    "Last Name",
    "Middle Name",
    "Sex",
    "Dob"
]);
