I rewrote some code for key generation for particular memory handling/protection reasons and it certainly provides some extra confidence to yourself and/or other if you find your implementation and four others all produce the same 10000 outputs with the same repeatable but random looking inputs. Usually specific and well chosen test vectors are available, but not always. I did have a cry/laugh at the function name of the deterministic "random" generator in mbedtls though and reminding me of the OpenBSD commentry on them. Unfortunately I forget the details of what was particularly alarming/funny though.
