  • a relevant example test

    this.startsignup = () => {         element(by.css('#protractorjs')).click();         this.waitforspinnerfinished();     }

  • output running test

  • failed: no element found using locator: by(css selector, '.spinner')

it's been while since wrote in protractor don't have place test work if change return in waitforspinnerfinished to:

return result === false;
