Behaviors

Vaurien provides a collections of behaviors, all of them are listed on this page. You can also write your own behaviors if you need. Have a look at Extending Vaurien to learn more.

blackout

Reads the packets that have been sent then hangs.

Acts like a pdb.set_trace() you’d forgot in your code ;)

delay

Adds a delay before or after the backend is called.

The delay can happen after or before the backend is called.

Options:

  • before: If True adds before the backend is called. Otherwise after (bool, default: True)
  • sleep: Delay in seconds (int, default: 1)

dummy

Transparent behavior. Nothing’s done.

error

Reads the packets that have been sent then send back “errors”.

Used in cunjunction with the HTTP Procotol, it will randomly send back a 501, 502 or 503.

For other protocols, it returns random data.

The inject option can be used to inject data within valid data received from the backend. The Warmup option can be used to deactivate the random data injection for a number of calls. This is useful if you need the communication to settle in some speficic protocols before the ramdom data is injected.

The inject option is deactivated when the http protocol is used.

Options:

  • inject: Inject errors inside valid data (bool, default: False)
  • warmup: Number of calls before erroring out (int, default: 0)

hang

Reads the packets that have been sent then hangs.

Acts like a pdb.set_trace() you’d forgot in your code ;)
