I wrap the execution with a bash script that basically looks like the following:
a.sh java Golf | tee output_dump b.sh python testing-tool.py | tee input_dump Then I run python interactive_runner.py b.sh -- a.sh It basically copies output of both programs, while still running the interactive tester. -Sam On Mon, Apr 15, 2019, 12:25 Marcel Ubach <[email protected]> wrote: > El sábado, 13 de abril de 2019, 23:53:06 (UTC+2), [email protected] > escribió: > > How do test Java interactive solution in general? > > > > I tried following two steps locally but it hangs.
