WGRDBES discussion needed: pooling design-related validation tests into a single function

[nmprista]

There is a need for function that aggregates the core design-related validation rules ahead of design estimation. This to avoid multiple independent developments of the same tests in different functions and allow for quick updates of all relevant tests if/when guidelines are updated.

E.g., is numSampled necessarily equal to nrows? this might change depending on guidelines on new examples -> it will be time-consuming to find and update all tests in all functions that might contact. Having all tests aggregated in a function would simplify the updates.

@rix133 @davidcurrie2001 is this still relevant?

[davidcurrie2001]

Possibly - do you have examples of functions that are currently doing these types of checks?

Reusing previous tests is OK but there is no need to restrict people to use this approach. Umbrella (integration) tests are good to use but having simple unrelated tests as well is also good to ensure consistency.
