Raise Exception If Script Fails

Solution 1:

If there is no error s will be 0:

from os import system
s=system("python tutorial.py")
assert  s == 0

Or use subprocess:

from subprocess import PIPE,Popen

s = Popen(["python" ,"tutorial.py"],stderr=PIPE)

_,err = s.communicate() # err  will be empty string if the program runs okassertnot err

Your try/except is catching nothing from the tutorial file, you can move everything outside the it and it will behave the same:

from os import system
test_passes = False

s = system("python tutorial.py")
test_passes = Trueassert test_passes
