A modern programming language that makes developers happier.

is there a way in Kotlin and Idea to programmatically have the execution stops (like a breakpoint) when in debug mode?

If you click on the breakpoint I believe you can write a code condition for when to break it. Is it what you're looking for?

I know that, but I wonder about that logic directly in the test source

You want to persist the breakpoint logic in the project itself? The good old
```foo()
bar()
debugDoNothing()
baz()```
might be a good indicator to "place your breakpoint here", and you could add your code to it.
As it's a test source, I don't think the extra branch will be a big performance issue

Do you mean like how you can do it by calling the C++ WinApi `DebugBreak()`  or the .NET Framework's `System.Diagnostics.Debugger.Break()` ? I don't think there's any such facility.
