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
