Grammar based generating

How it works?

Now it works as a binary operations generator without validating result. The grammar_generating.py generates a generator.py python script according to bin_grammar.g4. That generates the generated folder with test files named testfile{NO}.js, which contains the test cases.

Usage

(Assuming that you are in the grammar_based_generating folder)

1. Run grammar_generating.py with arguments you need

   ./grammar_generating.py --starter-element STARTER_ELEMENT

   required arguments:

   --starter-element STARTER_ELEMENT - Element of grammar to generate

   optional arguments:

   --test-count TEST_COUNT - Number of tests to generate

   --seed SEED_NO - Number of random seed

   -q - Hide debug information

2. Run generator.py

   ./generator.py

   Your test files are now generated, here is an example output:

(-6771397985115418)&(-8449399919839354),
(-1586649123906936)*(8892681406378659),
(7417463721077098)/(7755937561856221),
-6800068029534013,
8534292065816254,
8219444865984694,
427692400712034,
-4769654319939512,
(3916222245587407)*(-859047480842144),
-1761718781915079

3. Run the generated test(s) with JerryScript

   (Engine location may be different)

   ./../jerryscript/build/bin/jerry ./generated/testfile1.js

   At the moment you can only execute them separately, one by one.
