Rebuild more frequently for continuous testing

I'm using TDD and I can't find a way to get fast test feedback even on tiny projects.

There's a ~4-second delay between a save of a file and when a rebuild is launched, so I get the test run 5-7 seconds after a save. The delay is the same whether ì use the autotest of intellij or the plugin infinitest. I find that unnecessarily slow but I can't find a way to reduce this wait-time.

My settings : Build, Execution and deployment | compiler

clear output directory on rebuild is OFF
build project automatically is ON

If I force a build the test result comes immediately after build. I do find that a bit annoying though.

A while ago we could customize the autotest delay but that feature seems to have gone away.

What can I do to get much faster feedback cycles at least on toy projects?

Hi. Could you please provide idea.log and build.log after reproducing the problem?

Does it work after if you invoke File | Save All?

I am experiencing the same 4 second delay before the build starts when I tried with the IntelliJ IDEA 2019.2. This makes it really difficult to fast TDD. Any progress on fixing this issue?
