# testthat Testing your code is normally painful and boring. `testthat` tries to make testing as fun as possible, so that you get a visceral satisfaction from writing tests. Testing should be fun, not a drag, so you do it all the time. To make that happen, `testthat`: * Provides functions that make it easy to describe what you expect a function to do, including catching errors, warnings and messages. * Easily integrates in your existing workflow, whether it's informal testing on the command line, building test suites or using R CMD check. * Can re-run tests automatically as you change your code or tests. * Displays test progress visually, showing a pass, fail or error for every expectation. If you're using the terminal, it'll even colour the output. `testthat` draws inspiration from the xUnit family of testing packages, as well from many of the innovative ruby testing libraries, like [rspec](http://rspec.info/), [testy](http://github.com/ahoward/testy), [bacon](http://github.com/chneukirchen/bacon) and [cucumber](http://wiki.github.com/aslakhellesoy/cucumber/). I have used what I think works for R, and abandoned what doesn't, creating a testing environment that is philosophically centred in R.
Version 0.6 ------------------------------------------------------------------------------ * All `mutatr` classes have been replaced with ReferenceClasses. * Better documentation for short-hand expectations. * `test_dir` and `test_package` gain new `filter` argument which allows you to restrict which tests are run. -- Assistant Professor / Dobelman Family Junior Chair Department of Statistics / Rice University http://had.co.nz/ _______________________________________________ R-packages mailing list r-packa...@r-project.org https://stat.ethz.ch/mailman/listinfo/r-packages ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
