42.4 Integration tests

Integration tests are written inside the tests folder. Example:

root
|--src
|--tests
   |--integration_test.rs

Example of test file content:

use mypkg::my_fct;

#[test]
fn test_my_fct() {
  assert_eq!(my_fct(2), 10)
}

To run all test functions of a particular test file:

cargo test --test my_test_file
