If you like, you can configure your repository to be able to run a test
suite of some sort. You can do this by using ``setpref'' to set the
``test'' value to be a command to run, e.g.
\begin{verbatim}
% darcs setpref test "sh configure && make && make test"
\end{verbatim}
Or, if you want to define a test specific to one copy of the repository,
you could do this by editing the file \verb!_darcs/prefs/prefs!.
\begin{options}
--leave-test-directory, --remove-test-directory
\end{options}
Normally darcs deletes the directory in which the test was run afterwards.
Sometimes (especially when the test fails) you'd prefer to be able to be
able to examine the test directory after the test is run. You can do this
by specifying the \verb!--leave-test-directory! flag. Alas, there is no
way to make darcs leave the test directory only if the test fails. The
opposite of \verb!--leave-test-directory! is
\verb!--remove-test-directory!, which could come in handy if you choose to
make \verb!--leave-test-directory! the default (see
section~\ref{defaults}).
