| Types vs tests | 2023-08-18 | archive/2023/08/18/types-vs-tests |
|
Today, I saw a Twitter poll - "Poll: Imagine your team has to build a project with either types or tests. You can't have both.".
The results were:
- Types - 50.9%
- Tests - 49.1%
I was surprised by this.
If I can't add type declarations (type hints) or return types, I can still write tests to check what happens when different types are used.
I can also perform checks and throw errors or Exceptions if something isn't what I'd expect.
Here's the thing
I use types heavily, but I'd be more confident that my application would work if I had tests and that's the main objective when writing code for myself or clients and for my clients' customers.
