ttdo 0.0.6: Bugfix

A bugfix release of our (still small) ttdo package arrived on CRAN overnight. As introduced last fall, the ttdo package extends the most excellent (and very minimal / zero depends) unit testing package tinytest by Mark van der Loo with the very clever and well-done diffobj package by Brodie Gaslam to give us test results with visual diffs:

ttdo 0.0.5: Reflect tinytest update

A maintenance release of our (still small) ttdo package just arrived on CRAN. As introduced last fall, the ttdo package extends the most excellent (and very minimal / zero depends) unit testing package tinytest by Mark van der Loo with the very clever and well-done diffobj package by Brodie Gaslam to give us test results with visual diffs:

tinytest has an extension mechanism we use, and as tinytest was just upgraded to version 1.2.0 changing, among other nice extensions, one interface by allowing for a new error class argument, we had to rebuild as well in order to document the new argument.

The release was actually prepared three days ago when tinytest itself was updated, but we waited for the binaries at CRAN to be updated and rebuilt to take advantage of the fully automated submission and test process at CRAN.

The NEWS entry follow.

Changes in ttdo version 0.0.5 (2020-05-06)

  • Rebuilt under tinytest 1.2.0 to add support for class argument in error-code test predicates

ttdo 0.0.4: Extension

A first update release to the still very new (and still very small) ttdo package arrived on CRAN today. Introduced about two months ago in September, the ttdo package extends the most excellent (and very minimal / zero depends) unit testing package tinytest by Mark van der Loo with the very clever and well-done diffobj package by Brodie Gaslam.

Just how the package creation was motivated by our needs in teaching STAT 430 at Illinois, so does the extension code in this release which generalized how we extend the tinytest test predicates with additional arguments which help in the use of the PrairieLearn system (developed at Illinois) to provide tests, quizzes or homework. This release is mostly the work of Alton who is now also a coauthor.

The NEWS entries follow.

Changes in ttdo version 0.0.4 (2019-11-18)

  • Generalize tinytest extensions with additional arguments for test predicates (Alton in #2).

  • Use Travis CI for continuous integration off GitHub (Dirk).

Please use the GitHub repo and its issues for any questions.

ttdo 0.0.3: New package

A new package of mine arrived on CRAN yesterday, having been uploaded a few days prior on the weekend. It extends the most excellent (and very minimal / zero depends) unit testing package tinytest by Mark van der Loo with the very clever and well-done diffobj package by Brodie Gaslam. Mark also tweeted about it.

The package was written to address a fairly specific need. In teaching STAT 430 at Illinois, I am relying on the powerful PrairieLearn system (developed there) to provides tests, quizzes or homework. Alton and I have put together an autograder for R (which is work in progress, more on that maybe another day), and that uses this package to provides colorized differences between supplied and expected answers in case of an incorrect answer.

Now, the aspect of providing colorized diffs when tests do not evalute to TRUE is both simple and general enough. As our approach works rather well, I decided to offer the package on CRAN as well. The small screenshot gives a simple idea, the README.md contains a larger screenshoot.

The initial NEWS entries follow below.

Changes in ttdo version 0.0.3 (2019-09-08)

  • Added a simple demo to support initial CRAN upload.

Changes in ttdo version 0.0.2 (2019-08-31)

  • Updated defaults for format and mode to use the same options used by diffobj along with fallbacks.

Changes in ttdo version 0.0.1 (2019-08-26)

  • Initial version, with thanks to both Mark and Brodie.

Please use the GitHub repo and its issues for any questions.
