Hi everyone,
Here comes a http://cr.openjdk.java.net/~ykantser/8007142/webrev.01/ with following fixes compared to .00:
- new line is added at the end of** the StreamPumper.java
is changed to {@code in the StreamPumper.java- JDKToolFinder.java will use the system property "java.home" instead of "test.jdk" (thus -compilejdk problem is solved)
@Max
Yes, the library can launch a Java process, wait for it to finish, and collect all the output (stdout and stderr). There is no client/server solution yet, but as soon as we have testlibrary a lot of good utility classes can be put there.
This solution's use case is writing simple tests in jtreg without using shell scripts.
JcmdBase.java is an example of how it works.
class MyTest extends JcmdBase {
...
public void verify() { OutputAnalyzer output = jcmd("VM.version"); output.shouldContain("Java HotSpot"); }
...
}
As I've mentioned before it's almost a copy of http://cr.openjdk.java.net/~ctornqvi/webrev/8006413/webrev.03/ which has been reviewed and approved and on the way in into hotspot/test.
Thanks, Katja
