// |NetworkConditionService| without exposing them in the production code and
// remove code that would update its internal upload_rate_. Also unsubscribe
// from network condition change notified by
// g_browser_process->network_quality_tracker() in the constructor to avoid
// unexpected change in upload_rate_.
//
// Example Usage:
//
// TestingNetworkConditionService network_condition_service;
// network_condition_service.SetUploadRate(1000);
//
class TestingNetworkConditionService : public NetworkConditionService {
public:
// Unsubscribe from g_browser_process->network_quality_tracker() via the UI
// thread and clear the task queue on the UI thread immediately.
