#' Get ForceFrame repetitions by test ID

#' Calls the ForceFrame API endpoint `/tests/{testId}/repetitions` to retrieve
#' repetition records for a single test.
#'
#' @param ... The GUID of the ForceFrame test. Input as a string.
#' @return A data frame containing repetition details, or an empty data frame if none are found.
#' Internal function (not designed to be used directly by end users)
