    32 * Outline 

    33   - What software Testing is? 

    34   - Learn to test simple functions for their functionality.

    35   - Learn how to automate tests. 

    36   -  Need for coding style and some of the standards followed by the Python Community.

    37   -  Handling Errors and Exceptions.

    38

    40 * gcd function

    41   - Create gcd.py file with:

    42 #+begin_LaTeX

    43 \begin{lstlisting}[language=python]

    44   def gcd(a, b):

    45         if a % b == 0: 

    46             return b

    47         return gcd(b, a%b)

    48 \end{lstlisting}

    49 #+end_LaTeX

    50 

    51 * Test for gcd.py

    52   - Edit gcd.py file

    53 #+begin_LaTeX

    54 \begin{lstlisting}[language=python]

    55 

    56   def gcd(a, b):

    57       if b == 0:

    58           return a

    59       return gcd(b, a%b)

    60   

    61   if __name__=='__main__':

    62       result = gcd(48, 64)

    63       if result != 16:

    64           print "Test failed"

    65       print "Test Passed"

    66 \end{lstlisting}

    67 #+end_LaTeX

    68 

    69 * Automating tests

    70 #+begin_LaTeX

    71 \begin{lstlisting}[language=python]

    72 

    73     if __name=__='__main__':

    74     for line in open('numbers.txt'):

    75         numbers = line.split()

    76         x = int(numbers[0])

    77         y = int(numbers[1])

    78         result = int(numbers[2])

    79         if gcd(x, y) != result:

    80             print "Failed gcd test

    81                           for", x, y

    82 \end{lstlisting}
