  • What is the purpose of grouping the tests in a `tests` module like this
  • ```
  • #[cfg(test)]
  • mod tests {
  • use super::*;
  • #[test]
  • fn test_function_1() {
  • // test code for function 1 goes here
  • }
  • #[test]
  • fn test_function_2() {
  • // test code for function 2 goes here
  • }
  • }
  • ```
  • and is it possible to split them and have the test functions outside of the `tests` module?
  • ```
  • #[test]
  • fn test_function_1() {
  • // test code for function 1 goes here
  • }
  • #[test]
  • fn test_function_2() {
  • // test code for function 2 goes here
  • }

  • // test code for function 2 goes here
  • }
  • ```
  • I don't want to split them into their own directory.

#[test]
fn test_function_1() {
    // test code for function 1 goes here
}

#[test]
