> Would it make sense to have all custom expectations in {{R/}} , maybe {{R/test-helpers.R}} ? Reasons: 
>  
>  * edit(added on 12/01/2022): probably the most important point is these files are source by {{devtools::load_all()}} and, thus, helper functions are available interactively. 
>  * easier for newbies to read a file and figure out what custom testthat helpers we have
>  * easier to document
>  * respects the testthat author's suggestion to have them there
> Currently we have 17 different custom expectations, all defined in different files.
> A follow-up thought: maybe move all helpers there ({{{}is.{}}}, {{{}as_{}}}, {{{}compare_{}}}, {{verify}} etc).
