Dear list members,

I have a question about the interpretation of else branches. Let us
consider the following example:

testcase tc3() runs on MTCType
{
timer t5 := 5.0;

t5.start;
alt {
[] t5.timeout
{
log("t5 timeout");
}
[else]
{
log("else branch");
}
}
}

My question: Which branch of the alternative will be selected at the
first evaluation? Does it depend on whether the test executor is not
extremely slow and reaches the alt statement within 5 seconds?

Question 2: What will happen if we replace the timeout statement with a
receive statement performed on a port with empty queue?

Thanks in advance,

Zoltan

Yes this depends on the speed of your test executor. If the timeout
is already in the timout-list, the timeout branch will be chosen,
otherwise the else branch will be chosen.

The else-branch is chosen.

Hope this helps
