Initial status value

[SaitTalhaNisanci]

Currently we have a structure like this in our scripts:

status = 0
# run the test and assign the exit code to status
exit(status)

Wouldnt it be better to start with a nonzero status code so that if we dont run our tests the script will return with a nonzero code? Currently if the tests are not run the initial status which is 0 will be returned.

An example can be seen here:
