The process of validating Solana programs through unit tests, integration tests, and fuzz testing. Common approaches: Rust tests with solana-program-test or LiteSVM (fast, in-process), TypeScript tests with Bankrun or solana-test-validator (end-to-end), and fuzz testing with Trident. Best practice is testing both happy paths and attack vectors (missing signers, wrong owners).
The practice of developing and testing Solana programs against a local validator (solana-test-validator) or in-process test harness (Bankrun, LiteSVM). Local development allows instant transaction confirmation, free airdrops, account cloning from mainnet, and rapid debugging. Programs are deployed locally before moving to devnet for integration testing.

The most popular framework for building Solana programs in Rust. Anchor provides macros (#[program], #[account], #[derive(Accounts)]) that auto-generate boilerplate for account validation, serialization, discriminators, and error handling. It includes a CLI (anchor init/build/test/deploy), IDL generation, and TypeScript client generation. Reduces program code by ~80% compared to native development.
The Anchor macro applied to structs to define on-chain account data layouts. `#[account]` auto-derives Borsh serialization, adds an 8-byte discriminator prefix (SHA-256 of 'account:<Name>'), and implements space calculation. Optional attributes: `#[account(zero_copy)]` for zero-copy deserialization of large accounts.
The Anchor macro that defines the accounts struct for an instruction. Each field specifies an account with validation constraints. Account types include: `Account<'info, T>` (deserialized), `Signer<'info>` (must sign), `Program<'info, T>` (program reference), `SystemAccount<'info>`, and `UncheckedAccount<'info>` (no validation, use carefully).
Declarative validation rules on Anchor account fields. Key constraints: `#[account(mut)]` (writable), `#[account(init, payer=x, space=n)]` (create), `#[account(seeds=[...], bump)]` (PDA validation), `#[account(has_one=field)]` (field equality), `#[account(constraint = expr)]` (custom boolean), `#[account(close=target)]` (close and reclaim rent).
