Take the 2-minute tour ×  I need to measure how much of memory
do my JUnit tests consume.    1. So the most obvious (but not
convinient) way is to run JVM with arguments like "-Xms128m
-Xmx512m" and track when I'll get the OutOfMemory error.    2.
The second way is to request a heapdump after running all my
tests and then use Memory Analyzer Tool. But it isn't useful to
do this every time I'm running tests.  The desired way is, let's
say, to log memory consumption into a file with such values as
maximum memory consumption, average consumption, GC calls count
etc. Or even draw a diagram which will show how memory was used.
And the question is, are there any tools, or methods, or
instruments to do this? Or, maybe, my wishes are unreal and
naive and there is no way to gather such data?  Tests are
running under IntelliJ Idea with JUnit4. I'm free to use any
other environment. Thanks in advance for any advice!
