... I also found another solution reposter before:
----
\ctxlua{commands.testcase(condition)}
{ If true...}
{If false}

Note that both blocks (if-true and if-false) are mandatory.
Considering Wolfgang's last answer, it would be better to write:
----
\ctxcommand{testcase(condition)}
{ If true...}
{If false}
----
