The class BPWebDriverTestCase caches and reuses BPRemoteWebDriver instances between tests, to prevent having to start the browser for every test. But the caching mechanism doesn't reset cookies, so they carry over from one test to another. The cookies should be cleared (or drivers in which cookies have been set should not be reused).
