Re: [hono-dev] How to debug Hono-code

What do you exactly mean by "times out"? The unit test? Because I've never ever seen the Eclipse debugger time out in any way.

Hi Kai,

Thank you! Initially, I commented out the timeout rule. Now i increase the value to 3600 secs + use the vertxoptions as in 1. At least now I can inspect my breakpoints for 3-4 mins before it times out but not more. 3600 secs is 1 hour but it times out long before that. Any idea?

I do not think that running the adapter on a worker thread helps a lot. The
problem is more likely to be related to the test case itself timing out.

The VertxBasedHttpProtocolAdapterTest test class defines a Timeout rule at the
top of the class which defines a timout period of 5 seconds for each test case.
You may try to increase this value to e.g. 60 seconds in order for the test case
to not time out prematurely before you were able to inspect your breakpoints ...

Let me know if that works for you ...
