test-context

A library for providing custom setup/teardown for Rust tests without needing a test harness.

```rust use testcontext::{testcontext, TestContext};

struct MyContext { value: String }

impl TestContext for MyContext { fn setup() -> MyContext { MyContext { value: "Hello, world!".to_string() } }

fn teardown(self) {
    // Perform any teardown you wish.
}

}

[test_context(MyContext)]

[test]

fn testworks(ctx: &mut MyContext) { asserteq!(ctx.value, "Hello, world!"); } ```

Alternatively, you can use async functions in your test context by using the AsyncTestContext.

```rust use testcontext::{testcontext, AsyncTestContext};

struct MyAsyncContext { value: String }

[asynctrait::asynctrait]

impl AsyncTestContext for MyAsyncContext { async fn setup() -> MyAsyncContext { MyAsyncContext { value: "Hello, world!".to_string() } }

async fn teardown(self) {
    // Perform any teardown you wish.
}

}

[test_context(MyAsyncContext)]

fn testworks(ctx: &mut MyAsyncContext) { asserteq!(ctx.value, "Hello, World!"); } ```

The AsyncTestContext works well with async test wrappers like actix_rt::test or tokio::test.

```rust

[test_context(MyAsyncContext)]

[tokio::test]

async fn testworks(ctx: &mut MyAsyncContext) { asserteq!(ctx.value, "Hello, World!"); } ```
