What is CBTF?

A fuzzer for R packages that grew from one argument at a time to parallel runs across whole namespaces.

CBTF throws deliberately problematic inputs at exported functions and reports which ones error, warn, or survive. It now covers 85 input classes, fuzzes multiple named arguments per call, runs in parallel with a per-function timeout, and reports results as a classed object with print, summary, length, and whitelist methods for pruning false positives. Output control has been refined repeatedly — the latest release adds grouping by input or by function and a summary-only mode.

What is dqcheckr?

dqcheckr adds drift analysis, then removes the YAML a user had to hand-write.

dqcheckr runs configurable data-quality checks over files and DuckDB tables, driven by YAML dataset configs and recording results as snapshots. The 0.2.0 release added the ability to compare two historical snapshots and report per-column statistical drift, schema changes and trend charts, extending the tool from point-in-time checking into change over time. The most recent tag, 0.3.0, attacks the other friction point by generating the config itself from a sniff pass over the data.

0.0

A fuzzer for R packages that grew from one argument at a time to parallel runs across whole namespaces.

◆ Current state

CBTF throws deliberately problematic inputs at exported functions and reports which ones error, warn, or survive. It now covers 85 input classes, fuzzes multiple named arguments per call, runs in parallel with a per-function timeout, and reports results as a classed object with print, summary, length, and whitelist methods for pruning false positives. Output control has been refined repeatedly — the latest release adds grouping by input or by function and a summary-only mode.

◆ Where it's heading

The package has moved from a script-shaped tool to a test-suite component. The single-argument, sequential fuzz() of the early releases could not finish a large namespace or survive a function that simply hangs; the mirai rewrite fixed both, and multi-argument support widened what a run can actually reach. Nearly everything since has gone into making results triageable rather than merely produced: whitelisting, result classes, grouping, and terminal output that fits real function signatures. Note that the 0.1.0 through 0.3.0 entries carry backfilled timestamps recorded in reverse order within under a minute, so their published dates do not reflect release order.

◆ Prediction

The steady expansion of the input catalogue from 70 to 85 with a new time class suggests more input classes are the cheapest next win; the reporting surface is now detailed enough that machine-readable output for CI would be the natural follow-on.

dqcheckr adds drift analysis, then removes the YAML a user had to hand-write.

◆ Current state

dqcheckr runs configurable data-quality checks over files and DuckDB tables, driven by YAML dataset configs and recording results as snapshots. The 0.2.0 release added the ability to compare two historical snapshots and report per-column statistical drift, schema changes and trend charts, extending the tool from point-in-time checking into change over time. The most recent tag, 0.3.0, attacks the other friction point by generating the config itself from a sniff pass over the data.

◆ Where it's heading

Both moves point the same way: reduce what the operator has to write and know. Config generation removes the hand-authored YAML that gated first use, list_runs() and validate_config() make an existing setup inspectable, and the snapshot comparison turns accumulated run history into a second product surface. Check coverage keeps widening underneath — outlier detection, composite keys, row-count and file-size ceilings — and the reporting layer moved from rmarkdown to Quarto, with existing 0.1.x databases auto-migrated on first run.

◆ Prediction

Expect the generated configs and the drift reports to converge, so a sniffed config can seed thresholds from the snapshot history rather than from defaults, plus continued growth in the numbered QC check catalogue.
