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.
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.rsanderror.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.
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::processfunction matching the entrypoint signature. - ProgramTest and the relevant Solana program dependencies in the project.
Steps
Create a default
ProgramTestinstance.Set
prefer_bpf(false)to use the processor directly rather than loading a BPF binary.Register the program with its name, program ID and
processor!(Processor::process).Call
start_with_context().awaitto obtain aProgramTestContext.
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 undertarget/deploy/. - The documented pattern does not establish compatibility with every Solana toolchain version.
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
Use the repository's
tests/tests.rsapproach to stand up a local test validator.Run the integration tests against the validator listening on
localhost:8899.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.
