```

### To run **Test** functions:
In every ARC20 function the input values are declared in ```\input\arc20_leo.in```
Each Test function uses the algorithm of the original function and compares its output with the values coded into the test function.
In case the comparison is successful, the Test function will return True in a boolean variable.
