How to push a test case

• Create a new directory using the rule foo-bar or function_foo-function_bar
• Create benchmark.js and benchmark2.js files and add your bench code (look the other tests to get help).
• Copy Makefile.example from the root directory, rename it to Makefile.
• Type make inside your test case directory.

To run all the tests type make from project root directory.
