Miden Client Integration Tests

This directory contains integration tests for the Miden client library. These tests verify the functionality of the client against a running Miden node.

Features

• Parallel Execution: Run tests in parallel to significantly reduce total execution time
• Test Filtering: Filter tests by name patterns, categories, or exclude specific tests
• Flexible Configuration: Configurable RPC endpoints, timeouts, and parallel job counts
• Comprehensive Reporting: Detailed test results with timing statistics and progress tracking
• cargo-nextest-like Experience: Similar filtering and execution patterns as cargo-nextest

Installation

To install the integration tests binary:

make install-tests

This will build and install the miden-client-integration-tests binary to your system.

Usage

Running the Binary

The integration tests binary can be run with various command-line options:

miden-client-integration-tests [OPTIONS]

Command-Line Options

• -n, --network <NETWORK> - The network to use. Options are devnet, testnet, localhost or a custom RPC endpoint (default: localhost)
• -t, --timeout <MILLISECONDS> - Timeout for RPC requests in milliseconds (default: 10000)
• -j, --jobs <NUMBER> - Number of tests to run in parallel (default: auto-detected CPU cores, set to 1 for sequential execution)
• -f, --filter <REGEX> - Filter tests by name using regex patterns
• --contains <STRING> - Only run tests whose names contain this substring
• --exclude <REGEX> - Exclude tests whose names match this regex pattern
• --list - List all available tests without running them
• -v, --verbose - Show verbose output including individual test timings and worker information
• -h, --help - Show help information
• -V, --version - Show version information

Examples

Run all tests with default settings (auto-detected CPU cores):

miden-client-integration-tests

Run tests sequentially (no parallelism):

miden-client-integration-tests --jobs 1

Run tests with custom parallelism:

miden-client-integration-tests --jobs 8

List all available tests without running them:

miden-client-integration-tests --list

Run only client-related tests:

miden-client-integration-tests --filter "client"

Run tests containing "fpi" in their name:

miden-client-integration-tests --contains "fpi"

Exclude swap-related tests:

miden-client-integration-tests --exclude "swap"

Run tests with verbose output showing worker information:

miden-client-integration-tests --verbose

Run tests against devnet:

miden-client-integration-tests --network devnet

Run tests against testnet:

miden-client-integration-tests --network testnet

Run tests against a custom RPC endpoint with timeout:

miden-client-integration-tests --network http://192.168.1.100:57291 --timeout 30000

Complex example: Run non-swap tests in parallel with verbose output:

miden-client-integration-tests --exclude "swap" --verbose

Show help:

miden-client-integration-tests --help

Test Categories

The integration tests cover several categories:

• Client: Basic client functionality, account management, and note handling
• Custom Transaction: Custom transaction types and Merkle store operations
• FPI: Foreign Procedure Interface tests
• Network Transaction: Network-level transaction processing
• Onchain: On-chain account and note operations
• Swap Transaction: Asset swap functionality

Test Case Generation

The integration tests use an automatic code generation system to create both cargo nextest compatible tests and a standalone binary. Test functions that start with test_ are automatically discovered during build time and used to generate:

1. Individual #[tokio::test] wrappers - These allow the tests to be run using standard cargo test or cargo nextest run commands
2. Programmatic test access - A Vec<TestCase> that enables the standalone binary to enumerate and execute tests dynamically with custom parallelism and filtering

The discovery system:

• Scans all .rs files in the src/ directory recursively
• Identifies functions named test_* (supporting pub async fn test_*, async fn test_*, etc.)
• Generates test registry and integration test wrappers automatically

This dual approach allows the same test code to work seamlessly with both nextest (for development) and the standalone binary (for CI/CD and production testing scenarios), ensuring consistent behavior across different execution environments.

Writing Tests

To add a new integration test:

1. Create a public async function that starts with test_
2. The function should take a ClientConfig parameter
3. The function should return Result<()>
4. Place the function in any .rs file under src/

Example:

pub async fn test_my_feature(client_config: ClientConfig) -> Result<()> {
    let (mut client, authenticator) = client_config.into_client().await?;
    // test logic here
}

The build system will automatically discover this function and include it in both the test registry and generate tokio test wrappers.
