When I make a contribution to Wireshark, I need to test my implementation before I commit my changes.
One of my test cases is checking whether Wireshark captures and shows the packets correctly.
Therefore, I should create network traffic for this test case.
After some searching, I found a tool: Colasoft Packet Player.
Colasoft Packet Player is a UI tool and works at Windows. (I think it is a Windows Form Application). These properties were good for me since I was doing my tests by hand at Windows.
When I thought that I should do these tests automatically, I searched a way of making this. (I know there are many Windows and Linux tools which work from command line). Since Colasoft Packet Player doesn’t have an API, I should find a way of UI automation. (By the way, I want to use my PC especially keyboard and mouse, while the tests are running).
And I learned following:
– Understand Colasoft Packet Player UI by using Microsoft Spy. See my previous post for details.
– How to make Win32 API calls by using C#
As a result I have written following code for automating Colasoft Packet Player.
