/**
 * Fake [LogProxy] that collects all lines sent to it. Mimics the ADB logcat format without the
 * timestamp. [FakeLogProxy.d] will write a log like so:
 * ```
 * logger.d("TAG", "message here")
 * // writes this to the [logs] field
 * "D TAG: message here"
 * ```
 *
 * Logs sent to this class are collected as a list of strings for simple test assertions.
