Hi,
Thanks to John Elion for this contribution.
I have tried it on the Ant test cases. This makes the execution of the test
cases shorter by 3 minutes with 2 threads [ not sure what is the total time
because I also run the antunit tests ].
Some of our test cases do not support parallelism because they are creating and
dropping temporary directories and files which have the same names.
this makes errors looking like this one :
[junit] Testcase:
testNoAddNewLine(org.apache.tools.ant.filters.NoNewLineTest): Caused an
ERROR
[junit] Warning: Could not find file
/Users/antoine/dev/asf/ant-core/src/etc/testcases/filters/result/nonl to copy.
[junit]
/Users/antoine/dev/asf/ant-core/src/etc/testcases/filters/build.xml:111:
Warning: Could not find file

[junit] at
org.apache.tools.ant.taskdefs.Copy.copySingleFile(Copy.java:639)
Does someone have a suggestion about how to adapt the test cases to support
parallelism.
I was thinking of adding somewhere in the Ant codebase a utility class or
method to get the PID of the currently running process
and add the PID somewhere in the name of temporary folders created for tests.
Any thoughts on that ?
