# CBTF: Caught by the Fuzz! 

[![Lifecycle: experimental](https://img.shields.io/badge/lifecycle-experimental-orange.svg)](https://lifecycle.r-lib.org/articles/stages.html#experimental)

A very simple mechanism to fuzz-test the exported functions of an R package.

At the moment this is extremely limited: it operates only on the first

argument and it doesn't introduce any randomness. However, it's convenient

when there are a large number of functions to test.

## Usage

```{r}

library(CBTF)

funs <- get_exported_functions("mime")

what <- TRUE

fuzz(funs, what)

```

The first occurrence is a false positive, as the message returned indicates

that the input was checked and the function returned cleanly. The second case

instead reveals that the function didn't validate its input: indeed, it

expected an environment, and used the `$` operation on it without checking.
