The gear retracted due to a improper setting. The landing gear is checked in pre-flight, but somehow the front gear was not configured correctly for this test. So, it did what it was supposed to do...retract.
It says right in the description what happened, this was not a normal pre-flight check this was a maintenance check done during/after replacing a faulty piece of hardware. The mechanics failed to ensure the landing gear pins were installed which physically lock the gear into place and prevent them from retracting.
