Andrew, This is very interesting. Thank you for the reference.
Hi Alexei, please see my comments inline I've got few questions trying to understand your framework.
1. Why an interface Watcher extends Serializable?
Because it's for performance comparison between different vms. The runner will be serialized, so that the vm can load the right runner. You can consider it like serializing the configuration for the vm. 2. Is there any project which uses p-unit for testing? Why have you started
it?
Polepos (https://sourceforge.net/projects/polepos) is going to refactor its code to use p-unit. And I know serveral community members use p-unit to test concurrency performance(by running the existing JUnit tests). I started it because I found that I can't do something as I want with JUnit, :) like concurrency, performance test. Why do I have to start thread, and join, and check the result at the end of join everytime? why do I need to use System.currentMilliseconds and sysout... :) So I wrote p-unit. 3. Running tests in several VM is great, but how could I compare these
results?
There're serveral build-in reports in p-unit. The most straightforward one is pdf format, which contains performance chart. The results of different vm for the same method are shown in the same page, so that you can know which one is better easily. It's also easy to plugin your own report by implementing PUnitEventListener. 4. If I need to increase a parameter until the test fails and then
report the final value as a test performance metrics how this should be done in p-unit?
hm... this functionality is not supported in p-unit.... Thanks! On 6/22/07, Andrew Zhang <[EMAIL PROTECTED]> wrote:
