// This test takes a snapshot of the platform BrowserAccessibility tree and
// tests it against an expected baseline.
//
// The flow of the test is as outlined below.
// 1. Load an html file from content/test/data/accessibility.
// 2. Read the expectation.
// 3. Browse to the page, wait for the accessibility tree to load, optionally
// wait for certain conditions (such as @WAIT-FOR) and serialize the platform
// specific tree into a human readable string.
// 4. Perform a comparison between actual and expected and fail if they do not
// exactly match.
