Francesco Mari commented on OAK-6209:
-------------------------------------
[~maksim_kviatkouski], I think you can save the original {{PrintStream}} before
replacing it with the dummy. More or less, something like this:
{noformat}
PrintStream prev = System.out;
System.setOut(new PrintStream(new NullOutputStream(), false));
System.out.println("this is ignored");
prev.println("this is printed");
{noformat}
You can pass {{prev}} to the {{BenchmarkOutputStrategy}} when it's built, so
that the statistics are written to the "old" standard output, while the tests
are to whatever you pass to {{System#setOut}}.
> The benchmark runner should produce machine-friendly output

> The benchmark runner currently produce output in the following format.
> {noformat}
> Apache Jackrabbit Oak 1.8-SNAPSHOT
> # LoginTest C min 10% 50% 90% max
> N
> Oak-Segment-Tar 1 472 494 522 552 631
> 115
> # LoginLogoutTest C min 10% 50% 90% max
> N
> Oak-Segment-Tar 1 472 479 513 543 568
> 118
> {noformat}
> While this format is well formatted and easy to read, it's a pain to process
> with standard command line utilities. The benchmark runner should give the
> possibility to produce machine-friendly output, like the following.
> {noformat}
> LoginTest,Oak-Segment-Tar,1,472,494,522,552,631,115
> LoginLogoutTest,Oak-Segment-Tar,1,472,479,513,543,568,118
> {noformat}
