// This class can be used in tests to mimic a real downloader. It

// always returns a single URL for map files downloading and when

// asked for a file, creates a file with zero-bytes content on a disk.

|
// Because all callbacks must be invoked asynchronously, it needs a
|
|
// single-thread message loop runner to run callbacks.

// *NOTE*, this class is not thread-safe.
