FiddlerCore Page Performance Collector with SQLite database

Collects details of the web navigation by establishing the system level proxy with the help of FiddlerCore API for the duration of the execution of the test.

Running the project demo

Compile and run the project. It will create proxy and open the browser. in this browser instance, navigatt to some place. The console window will show the collected page element timings. When page it finished loading, stop the process through the IDE. The databse fiddler-data.db will be in Program/bin/Debug directory.

Integrating Fiddlercore in Tests

Include the following code from Program.cs into your project

proxy = new Monitor();
proxy.Start();
// your test case here
proxy.Stop();

The duration is computed from Fiddler session timers as

var timers = fiddler_session.Timers;
TimeSpan duration = (TimeSpan)(timers.ClientDoneResponse - timers.ClientBeginRequest);

Alternatively you can run the Program as standalone application while you are executing the test step in question.

The OnNotification, BeforeRequest and BeforeResponse events are not currently used. A replica of SQLite Helper (C#) project sources is included as the Sqlite.Utils namespace (Utils directory). This provides low-level, non-LINQ access to SQL database API.

Bugs

If the FiddlerCore proxy stops abnormally, the 'Use a proxy server for your LAN' setting will remain in the registry:

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
"ProxyEnable"=dword:00000001
