Introduction

A collection of Python scripts to generate test data for e.g. text fields. The generated string is copied to the clipboard for further usage.

The idea is based on PerlClip and the blog post counterstring: Self-Describing Test Data by James Bach.

Sometimes you need to test a text field or document with different kinds of stressful inputs. But, it can be a pain to prepare the text data. PerlClip is a tool that helps you do that.

Setup

This script requires the Python module pyperclip . Recommended way for installation: pip install pyperclip

For further information about pyperclip visit:

• pyperclip on Github
• pyperclip on PyPI

Tested with:

• Windows 10 & Python 3.6
• Linux Mint 18.2 & Python 2.7.12

Usage

usage: counterstring.py [-h] [-l LENGTH] [-m MARKER_CHAR] [-v]

A tool for generating counterstrings.

optional arguments:
  -h, --help            show this help message and exit
  -l LENGTH, --length LENGTH
                        maximum length to be generated. Minimum value is: 2
  -m MARKER_CHAR, --marker MARKER_CHAR
                        use a custom marker character. Make sure to escape
                        certain characters! Default: *
  -v, --version         shows version information

Examples

python counterstring.py -l 56 will generate the following string and paste it to your clipboard:
2*4*6*8*11*14*17*20*23*26*29*32*35*38*41*44*47*50*53*56*

The last asterisk represents the end of a 56 character long string.

Whereas python counterstring.py -l 18 -m \# will generate:
2#4#6#8#11#14#17#2
