Mock an R6 class — local_mocked_r6

This function allows you to temporarily override an R6 class definition. It works by creating a subclass then using local_mocked_bindings() to temporarily replace the original definition. This means that it will not affect subclasses of the original class; please file an issue if you need this.

Usage

local_mocked_r6_class(
  class,
  public = list(),
  private = list(),
  frame = caller_env()
)

Arguments

class: An R6 class definition.
public, private: A named list of public and private methods/data.
frame: Calling frame which determines the scope of the mock. Only needed when wrapping in another local helper.
