Test data is available from 1 November 2020 onwards from the MARS archive, but only data since 5 January 2021 is based on the final configuration. A daily updated test dataset is also available for the most recent 3 days on the FTP server.
If you have access to ECMWF systems you can retrieve test data from MARS archive using keywords:

If you don't have access to ECMWF computers but would still like to access a large subset of test data you can use ECMWF WebAPI service.
