Romain Manni-Bucau updated TOMEE-2176: -------------------------------------- Issue Type: Improvement (was: Bug) > Arquillian test cannot be run in parallel > ----------------------------------------- > > Key: TOMEE-2176 > URL: https://issues.apache.org/jira/browse/TOMEE-2176 > Project: TomEE > Issue Type: Improvement > Components: TomEE Arquillian Adapters > Affects Versions: 7.0.3 > Reporter: Thorsten Meinl > Priority: Minor > > In order to speed up tests, I wanted to run them in parallel using Maven > Surefire's parallel execution capabilities. But even when running every test > class in its own forked VM tests were failing randomly, mostly due to missing > files in the temporary container directory. The reason is that all temporary > containers will use the same directory, which is > {{dir = System.getProperty("java.io.tmpdir") + "/arquillian-apache-tomee"}} > and/or > {{appWorkingDir = System.getProperty("java.io.tmpdir") + > "/arquillian-tomee-app-working-dir}} > (see {{org.apache.openejb.arquillian.common.TomEEConfiguration}}). > This means different processes running TomEE via Arquillian will interfere > with each other, even completely independent process and even from different > users. > As a solution the above-mention directories must be created such that they > are unique for the process, e.g. by using > {{java.nio.Files.createTempDirectory}}. > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
