page source Actions funcunit.actions Actions are used to simulate user behavior such as clicking, typing, moving the mouse. Commands open - opens a page. click - clicks an element (mousedown, mouseup, click). dblclick - two clicks followed by a dblclick. rightClick - a right mousedown, mouseup, and contextmenu. type - types characters into an element. move - mousemove, mouseover, and mouseouts from one element to another. drag - a drag motion from one element to another. scroll - scrolls an element. Actions run asynchronously, meaning they do not complete all their events immediately. However, each action is queued so that you can write actions (and waits) linearly. S('textarea').click().type("Hello World"); S('.resizer').drag("+20 +20"); Common mistake Almost always before performing an action, you should perform a wait that makes sure the element you're operating on is ready. A common pattern is calling visible before most actions. S(".foo").visible().click() Without waits, tests may intermittently fail because of timing conditions. When click runs, it immediately simulates a click on the given element. Often, tests are triggering app behavior that renders elements in the page. If that element isn't present before the action runs, the test will fail.
