[infinispan-issues] [JBoss JIRA] (ISPN-1298) Configure fork=once so that TRACE logs can be gathered more easily

Configure fork=once so that TRACE logs can be gathered more easily ------------------------------------------------------------------ Key: ISPN-1298 URL: https://issues.jboss.org/browse/ISPN-1298 Project: Infinispan Issue Type: Enhancement Components: Test Suite Reporter: Galder Zamarreño Assignee: Galder Zamarreño Priority: Minor Labels: log4j, logging Fix For: 5.1.0.CR1 We currently run our testsuite with fork=none which causes us some small issues: - First, we're exposed to whatever system properties Maven might use internally which could impact our build. - Secondly, it makes it difficult to have per-project log4j settings that are not hardcoded in the source code. So, what is suggested here is that we switch to fork=once so that each module's testsuite runs in a different JVM. The overhead of this is apparently pretty small (needs double checking). In terms of logging, this potentially enables each module to have its own 'trace-enabling' profile pointing to its own TRACE enabled log4j file, making it quite easy for each module to define what TRACE is relevant for each. For example: {code} <project> <profiles> <profile> <id>trace-tests</id> <build> <plugins> <plugin> <artifactId>maven-surefire-plugin</artifactId> <configuration> <systemPropertyVariables> <log4j.configuration>${basedir}/src/test/trace/log4j.xml</log4j.configuration> </systemPropertyVariables> </configuration> </plugin> </plugins> </build> </profile> </profiles> </project> {code} This has another advantage which is allowing us to override the log output directory selectively which is handy in a CI environment such as CloudBees: - First, set the logs location to be dependant on another system property, i.e.: {code}location=${log4j.outputDirectory}/infinispan.log{code} - And then, selectively change it: {code}<systemPropertyVariables> <log4j.configuration>${basedir}/src/test/trace/log4j.xml</log4j.configuration> <log4j.outputDirectory>${project.build.directory}/test-logs</log4j.outputDirectory> </systemPropertyVariables>{code}
