For writing tests, it is often desirable to create a certain situation
that would be tedious, or even impossible to create by sending
individual transactions.
For example, a common attack vector on Solana is to create a copy of
some existing account that stores configuration data, but manipulate the
data stored there, and then to call a program and pass in the
manipulated account, instead of the real account.
If one wants to test this, one option is to write a program that you can
call to write arbitrary data into a new account account (and possibly
change its owner), then include that program in the test context, and
send a transaction to call it. This is extremely tedious, and developers
are not going to bother doing it. I myself would rather fork
solana-program-test to add this `set_account` method, than to write that
program. Having a “god mode” method to just write an account, lowers the
barrier to writing comprehensive tests.
A second reason for introducing this method, is defense in depth. There
may be states of the bank that are not reachable *yet* by only sending
transactions, but that you might want to test against either way. For
example, right now, the balance of a stake account cannot decrease
without going through the stake program. But what if Solana were to
introduce slashing in the future, and you want to ensure your program is
robust against decreases in stake account balance? Right now there is no
way to test this, but by introducing this “god mode” to write accounts,
the situation becomes testable.

* Improve program-test process_transaction() speed by reducing sleep duration in banks-server (#20508)
* banks_server: Reduce sleep duration for local server
This speeds up process_transaction_with_commitment_and_context()
and thus most program tests by a lot.
* Plumb tick duration through poh config and signature polling
