This test only checks that the property exists and works correctly in a very simple case. This blog post by kangax explains the history of this property, gives much more detailed cross-browser compatibility information, and gives a detailed strawman specification for the property. HTMLElement.innerText is similar to, but has some important differences from, the standard Node.textContent property.
