# 'should.py' usually checks that the command exits with 0.
# Other exit codes can be given

# The files differ
$ Exit code is exactly '1'
!EXIT_CODE: 1
diff demo/hello.should demo/cal.should

$ Exit code is not zero
!EXIT_CODE: +
diff demo/hello.should demo/cal.should

$ 'world' is in the diff

# Different exit codes may be tested for different commands
!EXIT_CODE: 0
