    ''' Purpose test the four functions that make up go

    # Your functions should work for ALL test cases!
    # Your functions are generalized to take in a parameter (argument passed into parameter)
    # and that the function will work on that argument you pass in!
    # We have different possibilities of tests and "boundary cases" which is like
    # the empty string "" (nothing)

    ####  testing separate()

    print( "separate( s3 ):", r3 )
    print( "separate( s4 ):", r4 )
    
    print()
    
    #### Testing join()
    
    sl1 = ['a', 'p', 'p', 'l', 'e']
    sl2 = [ 'wa', 'hoo', 'wa  ']
    
    r1 = go.join( sl1 )

    print( "join( sl1 ):", "'" + r1 + "'")
    print( "join( sl2 ):", "'" + r2 + "'" )
    
    print()
    
    #### Testing ints()

    ns1 = " 3 "
    ns2 = "12    11 -63"
    ns3 = "31 415 92 653 5 9"
    ns4 = " "
    
    r1 = go.ints( ns1 )

    print( "ints( ns3 ):", r3 )
    print( "ints( ns4 ):", r4 )
    
    print()
    
    ### Testing parse_phone_string()
    
    pn1 = "(201) 867-5309"
    pn2 = "8602941986"
    pn3 = "21 25 55 2368"
    pn4 = "888.799.9666"
    
    r1 = go.parse_phone_string( pn1 )
    r2 = go.parse_phone_string( pn2 )
    r3 = go.parse_phone_string( pn3 )
    r4 = go.parse_phone_string( pn4 )
    
    print( "parse_phone_string( pn1 ):", r1 )
    print( "parse_phone_string( pn2 ):", r2 )
    print( "parse_phone_string( pn3 ):", r3 )
    print( "parse_phone_string( pn4 ):", r4 )
