describe('Protractor Demo App', () => {
it('should add one and two', () => {
browser.get('http://juliemr.github.io/protractor-demo/');
element(by.model('first')).sendKeys(1);
element(by.model('second')).sendKeys(2);
element(by.id('gobutton')).click();
expect(element(by.binding('latest')).getText()).toEqual('3');
});
});
This test adds two numbers in a demo app and checks the result.
