SVN commands you must know as an Test Automation Engineer

In the course of automation and continuous integration , you will someday come across a stage where you have to perform svn operations . And obviously, using command line (forget fancy UIs to do your business) using command line. And then you will have to start digging in,  which will take a substantial amount time ...believe me.

How to use argparse module to create command line tools with Python?

Its been decades I have been using sys.argv for simple tasks related to argument parsing. But the thing is, sometimes we don't realize how good something is unless we use it . Like the argparse module.

The official document got me totally confused. So I wrote my own tutorial. Let's get started.

Exploring COLLECTIONS module from Python

The 'collections' module has some interesting methods that give us an edge over generic inbuilt tools . I want to explore them here today and show how you can use them .

namedtuple

Tuples are represented as (item1, item2, item2, ...) . They support indexing and one of the ways to use them is :

>>> from collections import namedtuple
>>> Car = namedtuple('Car','Price Mileage Colour Class')
>>> xyz = Car(Price = 100000, Mileage = 30, Colour = 'Cyan', Class = 'Y')
>>> print xyz
Car(Price=100000, Mileage=30, Colour='Cyan', Class='Y')
>>> print xyz.Class
Y

They turn tuples into convenient containers for simple tasks. With namedtuples, you don’t have to use integer indices for accessing members of a tuple.
