Henryk Sarat created SUREFIRE-1059:
--------------------------------------
Summary: Running tests in parallel seems to ignore threadCount
Key: SUREFIRE-1059
URL: https://jira.codehaus.org/browse/SUREFIRE-1059
Project: Maven Surefire
Issue Type: Bug
Reporter: Henryk Sarat
Priority: Blocker
I'm trying to run 6 tests in parallel in 2 threads. However, it seems like as
man threads launch at one time instead of just 2. My proof here is via the
Thread Id that I print out and because the test finishes in around 18seconds. I
expect the test to finish in about 38 seconds. I got to this number because I
have 6 methods that sleep for 10 seconds each. If 2 threads run in parallel,
then the total run time should be 6methods/2threads = 30 seconds (there there
is about 8 seconds of build time of everything else). Am I doing something
wrong? This is really blocking me from proceeding because I can't control my
resources correctly and I'm sure other people might be feeling this pain.
