Calculate coverage of code directly — code

This function is useful for testing, and is a thin wrapper around file_coverage() because parseData is not populated properly unless the functions are defined in a file.

code_coverage(
  source_code,
  test_code,
  line_exclusions = NULL,
  function_exclusions = NULL,
  ...
)

Arguments

source_code: A character vector of source code
test_code: A character vector of test code
line_exclusions: a named list of files with the lines to exclude from each file.
function_exclusions: a vector of regular expressions matching function names to exclude. Example print\\\. to match print methods.
...: Additional arguments passed to file_coverage()

Examples

source <- "add <- function(x, y) { x + y }"
test <- "add(1, 2) == 3"
code_coverage(source, test)
#> Coverage: 100.00%
#> /tmp/Rtmpy2g0ZE/source.R18854e06b895: 100.00%
