A Simple Package for Testing R Packages
Description
A minimal, dependency-free testing framework for R packages.
Write tests as simple R expressions that return TRUE, using assert() for
assertions (with informative error messages on failure), has_error() /
has_warning() / has_message() for testing conditions, and test_pkg() to
run all tests with full access to internal (non-exported) package
functions. Snapshot testing via Markdown files is also supported.
