Attribute Macro serial_test::file_serial

#[file_serial]

Available on crate feature file_locks only.

Allows for the creation of file-serialised Rust tests

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

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

Multiple tests with the file_serial attribute are guaranteed to run in serial, as per the serial attribute. Note that there are no guarantees about one test with serial and another with file_serial as they lock using different methods, and file_serial does not support nested serialised tests, but otherwise acts like serial.

It also supports an optional path arg e.g

#[test]
#[file_serial(key, "/tmp/foo")]
fn test_serial_one() {
  // Do things
}

#[test]
#[file_serial(key, "/tmp/foo")]
fn test_serial_another() {
  // Do things
}

Note that in this case you need to specify the name arg as well (as per serial). The path defaults to a reasonable temp directory for the OS if not specified.
