# test_Chapter8.py

# End to End Testing

## Syntax Errors -> Good IDE VS Code
## Init and Runtime Errors Exit Code 1 at runtime __init__ entrypoint issue
## Exception Errors -> Errors AFTER runtime that cause Exit Code 1 -> try except 'finally'
## UI/UX Testing aka the bouncing ball correct for the user
## Unit Testing -> isolate the class objects and test them individually aka breakpoints
## Assertion Testing -> Actual vs Expected Results Assert Class pytest


# pytest uses the assert object
# pip install pytest
import pytest

# test for api to calc $40

# test data mockito 'mock' examples to test results

def calc_add(x,y,z): #7,3,4  19 | 40
    return (x + y) * z

def test_addition1():
    result = calc_add(7,3,'4') # fail data type error int/str
    assert result == 40

def test_addition2():
    result = calc_add(7,3,4)
    assert result == 40 # pass actual 40 == expected 40
