Test mod code

Thoughts on adding these?

fn megaton_assert_msg<T: std::cmp::PartialEq + std::fmt::Debug>(&mut self, result: T, expected: T, msg: &str) {
        self.total_tests += 1;
        self.category_tests += 1;
        if result != expected {
            self.megaton_log(format!("Test number {:#?} failed: got {:#?}, expected {:#?}. Message: {:?}\n", self.total_tests, result, expected, msg).as_str());
        } else {
            self.passed_tests += 1;
            self.category_passed_tests += 1;
        }
    }

    fn megaton_assert_ok<T,E>(&mut self, result: Result<T,E>, msg: &str) -> Option<T> 
    where 
        T: std::fmt::Debug,
        E: std::fmt::Debug 
        {
        self.total_tests += 1;
        self.category_tests += 1;
        if result.is_err() {
            self.megaton_log(format!("Test number {:#?} failed: received Err: {:?}. Message: {:?}\n", self.total_tests, result.unwrap_err(), msg).as_str());
            return None;
        } else {
            self.passed_tests += 1;
            self.category_passed_tests += 1;
            return Some(result.unwrap());
        }
    }
    ```

I didn't see the functions that we were talking about in the meeting (like assert_ok), please make sure all changes are pushed

This lifetime will give a lot of trouble, recommend to just make it &'static
