Practical overview

When it fits

Use it when starting a vanilla Rust Solana program or looking for a concrete structure for instruction handling, account checks and integration tests.

Who it is for

  • Rust developers starting a Solana program.
  • Program authors organizing instruction handling and account validation.
  • Developers planning integration tests with ProgramTest or a local Solana test validator.

Documented uses

  • Create a conventional program layout with an entrypoint, library, instruction definitions and processor.
  • Define instruction variants and helper functions that construct `Instruction` values.
  • Validate account ownership, signer status and addresses before processing.
  • Test program behavior in-process with ProgramTest or against a local test validator.
Before you choose

Requirements & limits

The repository is public on GitHub. The provided sources do not specify pricing or account requirements.

  • The README presents a vanilla Solana program structure rather than a hosted builder or complete application.
  • Account checks are intended to happen before processing, including checks in helper functions used to parse account data.
  • ProgramTest offers a fast in-process option; the README says it omits validator validation and recommends BPF for syscall tests.
  • A local test validator covers real validator behavior and CLI workflows, but the README describes this approach as slower and recommends serial tests.
  • The README allows projects to add files such as state.rs and error.rs, or split complex programs into crates.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up a simple ProgramTest integration test

Register a program processor with ProgramTest and start an in-process test context.

Before you start

  • A Rust Solana program with a Processor::process function matching the entrypoint signature.
  • ProgramTest and the relevant Solana program dependencies in the project.

Steps

  1. Create a default ProgramTest instance.

  2. Set prefer_bpf(false) to use the processor directly rather than loading a BPF binary.

  3. Register the program with its name, program ID and processor!(Processor::process).

  4. Call start_with_context().await to obtain a ProgramTestContext.

Expected outcome

The test receives a context with a BanksClient, payer and latest blockhash for in-process integration testing.

Guide limitations

  • The README characterizes this approach as fast and suitable for parallel tests, but says it omits validator validation.
  • Use BPF when testing syscalls; the README says omitting prefer_bpf(false) makes ProgramTest look for a binary under target/deploy/.
  • The documented pattern does not establish compatibility with every Solana toolchain version.

Source-based practical guide

Run larger integration tests against a local validator

Use a local `solana-test-validator` for integration tests, including tests of CLI workflows.

Before you start

  • A Solana program and integration tests prepared to use a local validator.
  • The Solana CLI workflow being tested.

Steps

  1. Use the repository's tests/tests.rs approach to stand up a local test validator.

  2. Run the integration tests against the validator listening on localhost:8899.

  3. Run these slower tests serially, as the README recommends.

Expected outcome

Tests exercise validator behavior and can drive CLI applications through their normal command-line use.

Guide limitations

  • The README describes this approach as slow and recommends serial testing.
