I'd like to get a review on new regression tests on various GC-related
Brief overview of tests to be added:
Following tests verify that PrintGC and PrintGCDetails flags work and
emit appropriate output.
Tests grouped by GC in order to handle different GC logging format.
Test on PrintGCTimeStamps and PrintGCDateStamps flags. It verifies that
options and their
combinations emit appropriate output and verifies that time and date
stamps are not decreasing over time.
Test on PrintGCApplicationConcurrentTime and PrintGCApplicationStoppedTime.
It verifies that these options emit appropriate output.
Test on PrintGCTaskTimeStamps flah. It verifies that when this option
emit output only with parallel GC
and also verifies that all timestamps are not decreasing and for each GC
thread verifies that number of
reported task timestamps equal to expected number of tasks.
Test on PrintTenuringDistribution flag. It verifies that appropriate
output is emitted when this option is
turned on and also verifies that reported values lies between 0 and
*Testing done: manual testing and JPRT.
