The repository contains test files that caused various errors in the JerryScript lightweight JavaScript engine. The inputs are located in the tests folder, denoted by the issue number from the official GitHub repository.

The structure of each test case is as follows:

• <issue-number>/
  • <issue-number>-orig.js: Fuzzer-generated input that originally caused the error.
  • hash.txt: The JerryScript commit hash that reproduces the error.
  • test.sh: (generated by the scripts) Oracle for checking if the error is still present (return code 0) or not (return code 1).
  • <issue-number>-jerry: (generated by the scripts) Compiled JerryScript engine that contains the error.

The tools folder contains the proper ANTLR v4 grammar for the JavaScript language and additional Python scripts for supporting measurements.

To see how the oracle scripts are generated, and the JerryScript engine is built, check the demo.py script.
