CSV conformance
Verification
Scope
Names, problem counts, and column values of the PHP CSV reader for 120 corpus cases, through the Phit\read_csv() contract. Identical results at block sizes from 1 to 64 rows.
References
- Versions
- PHP 8.5.10
Data
- CSV conformance corpus
- 120 cases: delimiters, quoting, comments, blank lines, encodings, NA strings, type guessing, and declared types Source
Method
bin/generate-csv-conformance writes the PHP reader's results to the corpus. phit holds a byte-identical copy and checks its native reader against it. The CSV reading record compares these results with readr.
- Check
- Expected values and invariants of the package
