JarCasting
iron-test-helpers
A set of utility classes to make testing easier. For more details on the methods available, please check the documentation of mock-interactions.js and test-helpers.js
See: Documentation.
Usage
Mock Interactions
This is a set of methods to simulate mouse or keyboard interaction with an element.
import {pressSpace, tap} from '@polymer/iron-test-helpers/mock-interactions.js';
test('can be triggered with space', function(done) {
button.addEventListener('keydown', function() {
done();
});
pressSpace(button);
});
test('can be clicked', function(done) {
button.addEventListener('click', function() {
done();
});
tap(button);
});
Note on globals
Note that in version 3.x, importing mock-interactions.js and test-helpers.js will also set the window.MockInteractions and window.TestHelpers globals, respectively (and importing iron-test-helpers.js will set both). This is done only for backwards compatibility, and will be removed in the next major version. All users should migrate away from globals and onto direct ES module imports.
