Queries having multiple types
Describe the feature you'd like:
Happy to have a go at this!
When looking into this issue I opened with the React testing library I took a peek at the source code here to see if it could be fixed here. I noticed that some of the queries have the wrong types locally but are fine when published. For example in the below screenshot the queryByRole has three possible types, which include those of queryAllByRole and findByRole, which are the wrong types:
It looks like the type is only correct in the published packaged because the return type is explicitly defined here. I then found this todo (from 3 years ago!) when looking for the function implementation.
Suggested implementation:
Unsure yet, maybe adding an explicit return tuple type to buildQueries? I don't know the knock on effect this would have but it seems like a quick fix, screenshots below (only did return types for queryByRole and findByRole for brevity):
However I think the problem is bigger as the function implementation type deviates from the published type and could lead to unexpected behaviour. IMHO it would be better for the function implementation to create the type, not overwrite it.
