# Test Devices

In devtodev you can mark a device as a test device. You can do so in the [Users & Segments](/reports-and-functionality/project-related-reports-and-fuctionality/users.md#mark-as-cheater-or-tester) section or in Settings -> SDK -> [Test Devices](/reports-and-functionality/project-related-reports-and-fuctionality/settings.md#test-devices). 

The system will exclude from the reports all incoming events from the test devices (except Real-time dashboard). You can check the evets in Settings -> SDK -> Integration -> [Event Log](/reports-and-functionality/project-related-reports-and-fuctionality/settings.md#event-log) or in the Users & Segments section. 

When you mark the User card as a Tester, the log in the User card will not be cached and the events will appear much quicker. 

If the app is in test mode, all devices with this app are added automatically to the list of test devices (up to 100 users). You can switch to Production mode manually in Settings -> [General Settings](/reports-and-functionality/project-related-reports-and-fuctionality/settings.md#switch-to-production-mode).

## Users & Segments

In the [Users & Segment](/reports-and-functionality/project-related-reports-and-fuctionality/users.md) section you can find a specific user using filters. For example, search a specific Advertisig ID or IDFA.
