@ -74,6 +74,14 @@ Examples for modifying traceback printing::
py.test --tb=native # Python standard library formatting
py.test --tb=no # no traceback at all
The ``--full-trace`` causes very long traces to be printed on error (longer
than ``--tb=long``). It also ensures that a stack trace is printed on
**KeyboardInterrrupt** (Ctrl+C).
This is very useful if the tests are taking too long and you interrupt them
with Ctrl+C to find out where the tests are *hanging*. By default no output
will be shown (because KeyboardInterrupt is catched by pytest). By using this
option you make sure a trace is shown.
