Write unit tests for selected code

Source: R/ensure_that.R
ensure_that.Rd

This function queries an LLM to write unit tests for selected R code. To do so, it:

  • Initializes a ensurer(): an ellmer Chat() that knows how to write testthat unit tests.

  • Reads the contents of the active .R file as well as the current selection.

  • Opens a corresponding test file (creating it if need be).

  • Asks the LLM to write unit tests for the current selection, using the contents of the active .R file as context.

  • Streams the response into the corresponding test file.

Most ensure users will not need to interface with this function directly.
