internet-connection-breaker

Internet connection breaker.

Useful for testing web applications stability with internet connection gaps.

How to use:

1. Download python 3.X from http://www.python.org/downloads/ and install (select all features to install).

2. Clone internet-connection-breaker as .zip file and unzip it on your computer (example C:/internetConnectionBreaker).

3. Write full path to the project into environment variables (PATH).

4. Press the combination "Win+R", type "cmd" in the window and press Enter (run the console of Windows with administrator rules).

5. When your console opened you type "icb.py" and internet-connection-breaker will run on your computer with standart parameters*.

Internet-connection-breaker works with different parameters. Connection presented as the stream of waves. Wave is a period when internet connection is unstable.

Parameters of internet-connection-breaker:

breaks_amount - number of internet connection breaks in one wave ([0..n] integer)

rakes_pause - time in seconds between internet connection breaks ([0..n] integer)

breaks_duration - time in seconds of internet connection break ([0..n] integer)

wave_pause - time in seconds between waves ([0..n] integer)

wave_type - type of stream ("const", "up", "down", "heel")

What is wave type?

const - stream of waves looks like sinus graph

up - stream of waves where number of connection breaks incrementally changes from small value to big

down - stream waves where number of connection breaks incrementally changes from big value to small

heel - stream waves looks like normal distribution

The standard values of parameters:

breaks_amount = 4

breaks_pause = 2

breaks_duration = 3

wave_pause = 30

wave_type = "const"

How to run icb.py with no standard parameters?

In command line type icb.py [--name_option=value_option]

Example:

icb.py --breaks_amount=20 --breaks_pause=100 --breaks_duration=3 --wave_pause=20 --wave_type="up"

in this situation all parameters will changed

or

icb.py --breaks_amount=15

in this situation only breaks_amount will changed

If you use wi-fi connection or your connection named on another?

1. Open icb.py

2. Change the name of parameter connection_name

3. Save the file

Standard parameter is connection_name = "Подключение по локальной сети" (In Windows open "Network and Internet" -> "Network and Sharing Center" -> "Change adapter settings" and then copy the connection name)
