Testcontainers-rs is the official Rust language fork of http://testcontainers.org.

Usage

testcontainers is the core crate

The crate provides an API for working with containers in a test environment.

  1. Depend on testcontainers
  2. Implement testcontainers::core::Image for necessary docker-images
  3. Run it with any available runner testcontainers::runners::* (use blocking feature for synchronous API)

Example:

  • Blocking API (under blocking feature)
use testcontainers::{core::{IntoContainerPort, WaitFor}, runners::SyncRunner, GenericImage, ImageExt};

#[test]
fn test_redis() {
    let container = GenericImage::new("redis", "7.2.4")
        .with_exposed_port(6379.tcp())
        .with_wait_for(WaitFor::message_on_stdout("Ready to accept connections"))
        .with_network("bridge")
        .with_env_var("DEBUG", "1")
        .start()
        .expect("Failed to start Redis");
}
  • Async API
use testcontainers::{core::{IntoContainerPort, WaitFor}, runners::AsyncRunner, GenericImage, ImageExt};

#[tokio::test]
async fn test_redis() {
    let container = GenericImage::new("redis", "7.2.4")
        .with_exposed_port(6379.tcp())
        .with_wait_for(WaitFor::message_on_stdout("Ready to accept connections"))
        .with_network("bridge")
        .with_env_var("DEBUG", "1")
        .start()
        .await
        .expect("Failed to start Redis");
}

Ready-to-use images

The easiest way to use testcontainers is to depend on ready-to-use images (aka modules).

Modules are available as a community-maintained crate: testcontainers-modules
