Reworked the test suite so I can create tests for the stdlib.

[vvhitespace] / stdlib_tests / vv_test.py

import os, subprocess

compiler_path = '../vvc'
interpreter_path = '../vvi'
temp_file = './test.vvs'
path_to_tests = './'

tests = [
        # Format: ['filename_without_extension', 'string for stdin', 'string for expected stdout']
        ['0001_hello_world', '', 'Hello, world!\n'],
        ] 

for test in tests:
    subprocess.run([preprocessor, include_path, "-o", cpp_temp_file, path_to_tests + test[0] + src_extension])

        print('.', end='', flush=True)
    os.remove(temp_file)

print("")
