This PR proposes to unify the "return type" of
as.data.frame.testthat_results()to a data frame with 13 columns with predefined names, regardless of whether the input object is of length 0.Context and motivation
I often use testthat results in a CI context, where combining (i.e. rbinding) the results of tests for multiple packages into 1 data frame is quite useful. It happens sometimes that one of those objects is empty, in which case
as.data.frame(testResults)returns a0 x 0data frame, requiring further manipulation if we want to apply unified methods.
