+Utility classes to make testing easier.
+
+## Mock Interactions
+
+This is a set of methods to simulate mouse or keyboard interaction with an element. Include `mock-interactions.js` and then use them like so:
+
+```javascript
+test('can be triggered with space', function(done) {
+  button.addEventListener('keydown', function() {
+    done();
+  });
+  MockInteractions.pressSpace(button);
+});
+
+test('can be clicked', function(done) {
+  button.addEventListener('click', function() {
+    done();
+  });
+  MockInteractions.down(button);
+});
+```
