Unbescape test + benchmark repository

This is the repository of tests and benchmarks related to the Unbescape project: http://www.unbescape.org

Executing the benchmark

Simply clone or download this repository and execute the benchmark.sh script:

$ ./benchmark.sh
Syntax: "./benchmark.sh {language}"
(language = "html" | "xml" | "javascript" | "json" | "csv" | "java")

$ ./benchmark.sh html

For each language, the benchmark will compare several technologies and show the results of escaping and unescaping several inputs. For each of them, you will be able to see:

  • The time required for the execution (in nanosecs).
  • The comparison between the time required by Unbescape and other technologies (in percent, e.g. [350,14%]).
  • Whether the returned output was exactly the same object as the input (true = (*)), in order to improve performance.
  • The result of the escape/unescape operation itself, so that you can check its correctness.
