# Test & Error Handling

For simplifying the test and validation process, please set bidRequest.test=1, BlueSea will return test ads. Please note:

* The ads returned by this approach are only for testing purposes, they will not be used for settlement
* Please remove bidRequest.test=1 before your project is going live
* Refer to 8. Request Samples
* For iOS,  the imp.ext.skadn object is required

You can refer to this table and troubleshoot issues during testing
