CBTF 0.5.0 (2025-08-21)

  • Streamline the progress report from fuzz().
  • In case both an error and a warning are raised by the function being fuzzed, we now report the error; previously the warning was reported because of how tryCatch() is implemented.
  • The length() S3 method for objects of class cbtf now counts the total number of tests performed, instead of the number of inputs tested.
  • Add the tabulate argument to summary() to control whether the tabulation of results should be printed to the terminal or not.
  • Change the internal structure of the cbtf object to store the names of the functions fuzzed only once.
  • Store the values of the ignore_patterns and ignore_warnings options in the cbtf object.
  • Add the whitelist() function to remove false positives from a cbtf object.
  • Make test_input() recognise the "help" keyword, in which case it returns a vector of valid input classes.
  • Add the namify() function to help create a named list of custom input objects.

CBTF 0.4.0 (2025-07-31)

CRAN release: 2025-08-19

  • Don’t crash in get_exported_functions() if getNameSpaceExports() fails.
  • Store the error message in the results object also in case of whitelisted errors, so it can be reported from print(..., show_all = TRUE).
  • Add the tabulation shown in summary() as attribute "summary_table" of the data frame returned.
  • Make get_exported_functions() return only fuzzable functions, so that functions with no arguments are no longer returned.
  • Expand the documentation to satisfy the CRAN request.

CBTF 0.3.0 (2025-07-27)

  • Warnings containing the name of the function being fuzzed are no longer reported, to make their behaviour consistent with that of errors.
  • Add the package argument to fuzz() as an alternative and simpler way to specify the namespace where function names are searched.
  • Don’t consider primitives (such as list() or +) to be functions with no arguments (#5).
  • Make the what argument to fuzz() accept a list of inputs, so that the function can test multiple inputs in the same run.
  • Add function test_inputs() to return a configurable list of problematic inputs.
  • Add the listify_what argument to fuzz() so that each input in what is also tested in its listified version.
  • Provide the S3 method for length().
  • Make the output from summary() more informative and include a column with the inputs tested in the data frame returned.

CBTF 0.2.0 (2025-07-16)

  • Return an object with the raw results from fuzz() and provide S3 methods for summary() and print() (#1).
  • Skip functions that call readline(), as in an interactive session they stall waiting for user input (#4).
  • Skip non-existing function names and functions that accept no arguments.
  • Show a progress bar during fuzz().
  • Prettify the output from fuzz(), summary() and print().

CBTF 0.1.0 (2024-11-14)
