I want to count the parameters in the select attribute, but my test failed, here is my specification:

it('should count the number of option', function()) { expect(element(by.id('sorting_options')).all(by.tagName('option').count())).toBe(3); } 

he gives me an error:

Answer 1

Your code is garbled, here is the correct syntax:

 it('should count the number of option', function () { expect(element(by.id('sorting_options')).all(by.tagName('option')).count()).toBe(3); }); 

Answer 2

Alternatively, use the abstraction / wrapper around the selected input here :

 var SelectWrapper = require('select-wrapper'); var sorting = new SelectWrapper(by.id('sorting_options')); expect(sorting.getOptions().count()).toEqual(3);
