dittodb vs vdiffr: at a glance
What is dittodb?
dittodb has spent four years on CRAN link fixes and one DBI bump.
dittodb records and replays database interactions so tests can run without a live database, sitting behind DBI and dbplyr. The visible history splits cleanly in two: functional work through 0.1.8 broadening which databases and situations can be captured, then three consecutive maintenance releases. The most recent adds DBI 1.3.0 compatibility and nothing else.
What is vdiffr?
vdiffr finished its job in 2021 and has been tracking compilers ever since.
vdiffr generates deterministic SVG snapshots so plot changes show up as test failures. Its recent history is almost entirely toolchain: UCRT Windows compatibility twice, a revert to C++11 to work around a GCC issue, and renaming the internal SVG device so it stops colliding with svglite. The only functional additions in view are snapshot variants in 1.0.8 and a testthat fix so snapshots are no longer auto-deleted when a test errors or skips. The last release was October 2024.

dittodb
0.0INFRA · APIS
dittodb has spent four years on CRAN link fixes and one DBI bump.
◆ Current state
dittodb records and replays database interactions so tests can run without a live database, sitting behind DBI and dbplyr. The visible history splits cleanly in two: functional work through 0.1.8 broadening which databases and situations can be captured, then three consecutive maintenance releases. The most recent adds DBI 1.3.0 compatibility and nothing else.
◆ Where it's heading
The functional direction was always coverage: more databases, more situations that can be mocked, better failure messages when the recording setup is wrong. That work stopped after 0.1.8 in 2024, and the package has since only answered CRAN link checks and a DBI release. Full transaction support with separate mock directories was flagged as planned back in 0.1.4 and has not appeared.
◆ Prediction
The last three releases are pure upkeep, so the next most likely tracks another DBI or dbplyr change rather than delivering the transaction support still outstanding.
vdiffr
0.0INFRA · APIS
vdiffr finished its job in 2021 and has been tracking compilers ever since.
◆ Current state
vdiffr generates deterministic SVG snapshots so plot changes show up as test failures. Its recent history is almost entirely toolchain: UCRT Windows compatibility twice, a revert to C++11 to work around a GCC issue, and renaming the internal SVG device so it stops colliding with svglite. The only functional additions in view are snapshot variants in 1.0.8 and a testthat fix so snapshots are no longer auto-deleted when a test errors or skips. The last release was October 2024.
◆ Where it's heading
The package reached its intended shape at 1.0.0, when snapshot management moved to testthat and vdiffr shed most of its own R and JavaScript code to become a reproducible SVG engine and nothing more. There is not much left to add to that, and the release stream since reads accordingly: it moves when a compiler, an R version, or testthat moves. For a testing dependency this is a healthy end state, though it does mean the package inherits whatever the graphics engine does to snapshot stability.
◆ Prediction
The entries do not support predicting a feature release. The likely next change is a compatibility fix prompted by a compiler or a testthat change, as every release since 1.0.2 has been.
