case object UninitializedDriver extends GrumpyDriver with Product with Serializable

An implementation of WebDriver that throws UnsupportedOperationException from all of its methods, used to initialize instance vars of type WebDriver.

Traits OneBrowserPerTest, ConfiguredBrowser, AllBrowsersPerSuite, and AllBrowsersPerTest initialize their webDriver field with this value (to avoid initializing with null).

This is an example of the "Null Object Pattern." We use this pattern to avoid initializing with null instead of making the driver type an Option[WebDriver] for two reasons: 1) the type of the implicit needed by Selenium is WebDriver, not Option[WebDriver], and 2) the UnsupportedOperationException thrown by the methods of the Null Object we provide carries a user-friendly error message.
