Test for compilation course

This code is not interesing if you are not working with me on that course ;)

See the file test.py for all tests.

Tips

You can add the environment variable FAST to generate faster (but less exhaustives) tests.

• no FAST : exhaustives tests, can be slow (2 minutes on my computer)
• FAST=1 : one case per testcase, quick (<1s), but not exhaustive
• FAST=10 : quick (2s), only 10 cases per testcase, but usually enough

Usage

The PYTHONPATH environment variable must be set to the path of the MyMuCodeGenVisitor.py file.

Run and get the assembly for a mu file, for example, exemple.mu :

a = 0;
n = 3;
while(a < n)
{
   a = a + 1;
}

$ PYTHONPATH=../MIF08_TP4/StudFilesTP4 python2 test_utils.py exemple.mu 
assign statement, rightexpression is:
(expr (atom 0))
assign statement, rightexpression is:
(expr (atom 3))
assign statement, rightexpression is:
(expr (expr (atom a)) + (expr (atom 1)))
