I'm trying out Protractor to e2e test Angular app and haven't figured out how to detect if an element has a specific class or not.
In my case, the test clicks on submit button and now I want to know if form[name="getoffer"] has class .ngDirty. What may be the solutions?
describe('Contact form', function() {
beforeEach(function(){
browser.get('http://localhost:9000');
element(by.linkText('Contact me')).click();
});
it('should fail form validation, all fields pristine', function() {
element(by.css('.form[name="getoffer"] input[type="submit"]')).click();
expect(element(by.name('getoffer'))).toHaveClass('ngDirty'); // <-- This line
});
});
One gotcha you have to look out for with using toMatch()
, as in the accepted answer, is partial matches. For instance, let's say you have an element that might have the classes correct
and incorrect
, and you want to test that it has the class correct
. If you were to use expect(element.getAttribute('class')).toMatch('correct')
, that will return true even if the element has the incorrect
class.
My suggestion:
If you want to only accept exact matches, you can create a helper method for it:
var hasClass = function (element, cls) {
return element.getAttribute('class').then(function (classes) {
return classes.split(' ').indexOf(cls) !== -1;
});
};
You can use it like this (taking advantage of the fact that expect
automatically resolves promises in Protractor):
expect(hasClass(element(by.name('getoffer')), 'ngDirty')).toBe(true);
