Hi Mikkel!

What are you using to run your tests? The run_test command, or are you
starting them from an erlang shell?

Also have you seen this problem when not using ct_ssh? or is it only
when you are doing tests with ssh calls in them?

If you could provide me with a minimal test suite which reproduces the
error you are seeing that would be great!

        Hi list!
        I have been working on setting up a test case using Erlang
        Common Test. The
        test is pretty simple, it consists of a sequence of calls to
        Running the test once works. Running the test a few times (using
        usually works. But if i let the test suite repeat a large number
        of times,
        it fails after successfully running the test multiple times (In
        my last
        attempt it completed 42 runs, no joke, but it seems like the
        repeated runs
        can stop at any time).
        The error i'm getting is:
        It is not possible to install CT while running in interactive
        To exit this mode, run ct:stop_interactive().
        To enter the interactive mode again, run ct:start_interactive()
        Does anyone know how i can avoid this, allowing me to run a
        large number of
        repeated tests?
        On a sidenote: I have noticed in the logs that ct_ssh will
        sometimes have
        lost its connection when trying to call ct_ssh:exec(), and thus
        will attempt
        to reconnect. This attempt will, however, always fail instantly.
        workaround i have made is to manually connect on each call i
        make to
        ct_ssh:exec(). This seems less than ideal, is there a better
        Kind regards and thanks in advance,
