println!("Bump: {}", bump);
// Create PDA account manually (for testing)
svm.set_account(pda, Account {
lamports: 1_000_000,
data: vec![bump], // Store bump seed in data
owner: program_id,
executable: false,
rent_epoch: 0,
}).unwrap();
// Verify PDA was created

}

Key Points

  1. PDA Derivation: Use Pubkey::find_program_address() to derive PDA addresses
  2. Seeds: PDAs are derived from seeds and the program ID
  3. Bump Seed: The bump seed ensures the address is off the ed25519 curve
  4. Account Creation: Use set_account() to manually create accounts for testing
  5. Ownership: PDAs must be owned by the program that derived them
