In all my professional experiences so far I've seen a lot of people/teams ignoring the meaning behind a Pull Request (PR), treating it like a kind of bureaucracy to deploy their piece of code.

We can't automate everything, people think by using automated tests they don't have to do anything else to guarantee the code quality.

Just a brief explanation of what is a Result container, basically your code can take two ways:

  • Success, the function computation was successfully executed
  • Failure, the function computation broke due to business…
