Crossrail test trains

[mat64nl]

Hello everyone,
I have noticed the time of crossrail 345s beginning passenger services have been pushed back to June, however, I have seen videos surface on YouTube that have Crossrail test units on the GEML.

Does anyone here have access to see if there are any Crossrail test services running on Friday evening/night ? (Preferably between London Liv St and Harold Wood)

Many thanks
