serial_test allows for the creation of serialised Rust tests using the serial attribute e.g.

#[test]
#[serial]
fn test_serial_one() {
  // Do things
}

#[test]
#[serial]
fn test_serial_another() {
  // Do things
}

#[tokio::test]
#[serial]
async fn test_serial_another() {
  // Do things asynchronously
}

Multiple tests with the serial attribute are guaranteed to be executed in serial. Ordering of the tests is not guaranteed however.

We require at least Rust 1.39 for async/await support

Add to your Cargo.toml

[dev-dependencies]
serial_test = "*"

plus use serial_test::serial; (for Rust 2018) or

#[macro_use]
extern crate serial_test;

for earlier versions.

You can then either add #[serial] or #[serial(some_text)] to tests as required.
