This is the general gist of the structure I've been creating.
I'm thinking of making builder methods for the SearchEngineDefinition as well later.

Right now, the builder methods are not being called:

• pub fn identifier
  

• pub fn name
  

• pub fn search_url
  

But I did test them out to create different custom types of full or minimal engine records.
Let me know what you think or which parts should be changed.
If it generally looks good, I'll continue with the pattern for the rest of the tests.

Thank you, I like the approach here.

I think the one improvement I'd suggest is to always require an identifier to be passed in for the engines. For example the test would read as:

                test_helpers::EngineRecord::full().build(),
                test_helpers::EngineRecord::minimal().build(),

Although we can probably assume in that order they would be 1 and 2, if I change the order do the ids change as well? Hence, I think it would be better to pass the identifier in - we require this for the existing JS test utils, so I think its fine to reflect that here.

Marking as request changes, so I'll get notified/a signal when there's updates.

I changed all tests in selector.rs

I will put up a different PR for the other tests in filter.rs. This refactor is already very big.
