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
}
~~```~~

I don't want to split them into their own directory.
