> How many tests does a PR need?

Enough test for each of your spec. Adding a new functionality to your product? Your test should cover and the cases you put in your specs. Correcting a bug? You test should trigger it with the old code.

You can have 100% code coverage with unit testing, it will do jack-shit for your users when they enter a negative number and there was no code meant to manage this case so it never was tested.
