Harmison made his debut in Tests, so did Monty. Hoggard certainly did. Come to think of it, so did Flintoff. Simon Jones too.It generally is for the England team. Most of our players our blooded in the shorter format first.
Basically, all the best bowlers made their debut in tests, because they're test specialists (apart from Flintoff). It's no surprise, therefore, that those who come on the strength of the ODI game only, aren't as successful.
And that's why I suggest don't pick Anderson just because his OD performances have been good.
