Soroban Test

Test framework wrapping Soroban CLI.

Provides a way to run tests against a local sandbox; running against RPC endpoint coming soon.

Overview

• TestEnv is a test environment for running tests isolated from each other.
• TestEnv::with_default invokes a closure, which is passed a reference to a random TestEnv.
• TestEnv::new_assert_cmd creates an assert_cmd::Command for a given subcommand and sets the current directory to be the same as TestEnv.
• TestEnv::cmd is a generic function which parses a command from a string. Note, however, that it uses shlex to tokenize the string. This can cause issues for commands which contain strings with "s. For example, {"hello": "world"} becomes {hello:world}. For that reason it's recommended to use TestEnv::cmd_arr instead.
• TestEnv::cmd_arr is a generic function which takes an array of &str which is passed directly to clap. This is the preferred way since it ensures no string parsing footguns.
• TestEnv::invoke a convenience function for using the invoke command.

Example

use soroban_test::{TestEnv, Wasm};

const WASM: &Wasm = &Wasm::Release("soroban_hello_world_contract");
const FRIEND: &str = "friend";

#[test]
fn invoke() {
    TestEnv::with_default(|workspace| {
        assert_eq!(
            format!("[\"Hello\",\"{FRIEND}\"]"),
            workspace
                .invoke(&[
                    "--id",
                    "1",
                    "--wasm",
                    &WASM.path().to_string_lossy(),
                    "--",
                    "hello",
                    "--to",
                    FRIEND,
                ])
                .unwrap()
        );
    });
}

Itegration tests in Crate

Currently all tests that require an RPC server are hidden behind a it feature, found here. To allow Rust-Analyzer to see the tests in vscode, .vscode/settings.json. Without RA, you can't follow through definitions and more importantly see errors before running tests tests.
