case object UnneededDriver extends GrumpyDriver with Product with Serializable

An implementation of WebDriver that throws UnsupportedOperationException from all of its methods, used when a test does not need a Selenium WebDriver at all.

Traits OneBrowserPerSuite, OneBrowserPerTest, AllBrowsersPerTest, and MixedFixtures check if the requested WebDriver is available, and if not, installs this driver (to avoid initializing with null) and cancels the tests.

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.
