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

```rust
use testcontainers::{core::{IntoContainerPort, WaitFor}, runners::SyncRunner, GenericImage};

#[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"))
        .start()
        .expect("Redis started");
}
```

- Async API

```rust
use testcontainers::{core::{IntoContainerPort, WaitFor}, runners::AsyncRunner, GenericImage};

#[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"))
        .start()
        .await
        .expect("Redis started");
}
```

### 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](https://github.com/testcontainers/testcontainers-rs-modules-community)
