Trdelník is Rust based testing framework providing several convenient developer tools for testing Solana programs written in [Anchor](https://github.com/project-serum/anchor). - **Trdelnik client** - build and deploy an Anchor program to a local cluster and run a test suite against it; - **Trdelnik console** - built-in console to give developers a command prompt for quick program interaction; - **Trdelnik fuzz** - property-based and stateful testing; - **Trdelnik explorer** - exploring a ledger changes.
Trdelnik Demo
## Dependencies - Install [Rust](https://www.rust-lang.org/tools/install) (`nightly` release) - Install [Solana tool suite](https://docs.solana.com/cli/install-solana-cli-tools) (`stable` release) - Install [Anchor](https://book.anchor-lang.com/chapter_2/installation.html) ## Installation ```shell cargo install trdelnik-cli # or the specific version cargo install --version trdelnik-cli ``` ## Usage ```shell # navigate to your project root directory trdelnik init # it will generate `.program_client` and `trdelnik-tests` directories with all the necessary files trdelnik test # want more? trdelnik --help ``` ### How to write tests? ```rust // /trdelnik-tests/tests/test.rs // TODO: do not forget to add all necessary dependencies to the generated `trdelnik-tests/Cargo.toml` use program_client::my_instruction; use trdelnik_client::*; use my_program; #[throws] #[fixture] async fn init_fixture() -> Fixture { // create a test fixture let mut fixture = Fixture { client: Client::new(system_keypair(0)), // make sure your program is using a correct program ID program: program_keypair(1), state: keypair(42), }; // deploy a tested program fixture.deploy().await?; // call instruction init my_instruction::initialize( &fixture.client, fixture.state.pubkey(), fixture.client.payer().pubkey(), System::id(), Some(fixture.state.clone()), ).await?; fixture } #[trdelnik_test] async fn test_happy_path(#[future] init_fixture: Result) { let fixture = init_fixture.await?; // call the instruction my_instruction::do_something( &fixture.client, "dummy_string".to_owned(), fixture.state.pubkey(), None, ).await?; // check the test result let state = fixture.get_state().await?; assert_eq!(state.something_changed, "yes"); } ``` Make sure your program is using a correct program ID in the `derive_id!(...)` macro and inside `Anchor.toml`. If not, obtain the public key of a key pair you're using and replace it in these two places. To get the program ID of a key pair (key pair's public key) the `trdelnik key-pair` command can be used. For example ``` $ trdelnik key-pair program 7 ``` will print information about the key pair received from `program_keypair(7)`. #### Instructions with custom structures - If you want to test an instruction which has custom structure as an argument ```rust pub struct MyStruct { amount: u64, } // ... pub fn my_instruction(ctx: Context, data: MyStruct) { /* ... */ } ``` - You should add an import to the `.program_client` crate ```rust // .program_client/src/lib.rs // DO NOT EDIT - automatically generated file pub mod my_program_instruction { use trdelnik_client::*; use my_program::MyStruct; // add this import // ... } ``` - This file is automatically generated but the **`use` statements won't be regenerated** #### Skipping tests - You can add the `#[ignore]` macro to skip the test. ```rust #[trdelnik_test] #[ignore] async fn test() {} ``` #### Testing programs with associated token accounts - `Trdelnik` does not export `anchor-spl` and `spl-associated-token-account`, so you have to add it manually. ```toml # /trdelnik-tests/Cargo.toml # import the correct versions manually anchor-spl = "0.28.0" spl-associated-token-account = "2.0.0" ``` ```rust // /trdelnik-tests/tests/test.rs use anchor_spl::token::Token; use spl_associated_token_account; async fn init_fixture() -> Fixture { // ... let account = keypair(1); let mint = keypair(2); // constructs a token mint client .create_token_mint(&mint, mint.pubkey(), None, 0) .await?; // constructs associated token account let token_account = client .create_associated_token_account(&account, mint.pubkey()) .await?; let associated_token_program = spl_associated_token_account::id(); // derives the associated token account address for the given wallet and mint let associated_token_address = spl_associated_token_account::get_associated_token_address(&account.pubkey(), mint); Fixture { // ... token_program: Token::id(), } } ``` - The `trdelnik init` command generated a dummy test suite for you. - For more details, see the [complete test](examples/turnstile/trdelnik-tests/tests/test.rs) implementation. ### Supported versions - We support `Anchor` and `Solana` versions specified in the table below. | Trdelnik CLI | Anchor | Solana | |--------------|:---------:|---------:| | `latest` | `~0.28.*` | `=1.16.6` | | `v0.4.0` | `~0.27.*` | `>=1.15` | | `v0.3.0` | `~0.25.*` | `>=1.10` | | `v0.2.0` | `~0.24.*` | `>=1.9` | - _We are exploring a new versions of Anchor, please make sure you only use the supported versions. We are working on it :muscle:_ ### Configuration The configuration variables can be edited in the `Trdelnik.toml` file that'll be generated in the root of the project. | Name | Default value | Description | |----------------------------------|---------------|-----------------------------------------------------------------------------| | `test.validator_startup_timeout` | 10 000 | Time to wait for the `solana-test-validator` in milliseconds before failure | ## Roadmap - [x] Q1/22 Trdelnik announcement at Solana Hacker House Prague - [x] Trdelnik client available for testing - [x] Q2/22 Trdelnik explorer available - [x] Q2/22 Trdelnik client and explorer introduced at Solana Hacker House Barcelona - [ ] Q3/23 Trdelnik fuzz introduced at Solana Hacker House Berlin ## Awards **Marinade Community Prize** - winner of the [Marinade grant](https://solana.blog/riptide-hackathon-winners/) for the 2022 Solana Riptide Hackathon. ## Contribution Thank you for your interest in contributing to Trdelník!
