A comprehensive test suite for RFC 8259 compliant JSON parsers
This repository was created as an appendix to the article Parsing JSON is a Minefield 💣.
/parsers/
This directory contains several parsers and tiny wrappers to turn the parsers into JSON validators, by returning a specific value.

/test_parsing/
The name of these files tell if their contents should be accepted or rejected.
y_content must be accepted by parsersn_content must be rejected by parsersi_parsers are free to accept or reject content
/test_transform/
These files contain weird structures and characters that parsers may understand differently, eg:
- huge numbers
- dictionaries with similar keys
- NULL characters
- escaped invalid strings
These files were used to produce results/transform.html.
/run_tests.py
Run all parsers with all files:
$ python3 run_tests.py
Run all parsers with a specific file:
$ python3 run_tests.py file.json
Run specific parsers with all files:
$ echo '["Python 2.7.10", "Python 3.5.2"]' > python_only.json
$ python3 run_tests.py --filter=python_only.json
The script writes logs in results/logs.txt.
The script then reads logs.txt and generates results/parsing.html.
