-------------------------------------------
Summary: Tests from dependency jar ignore parallel execution
Key: SUREFIRE-1149
URL: https://jira.codehaus.org/browse/SUREFIRE-1149
Project: Maven Surefire
Issue Type: Bug
Components: Junit 4.7+ (parallel) support, Maven Failsafe Plugin,
Maven Surefire Plugin, process forking
Affects Versions: 2.18.1
Reporter: Christopher Smith
Attachments: pom.xml
I have a Selenium test suite that is contained in a module of my main
application but that needs to be run against an instance deployed to a staging
environment. I package the tests into a jar and have a separate POM that
declares {{dependenciesToScan}} and is executed in a later CI step. The tests
execute, but the runner completely ignores any parallel configuration: neither
{{parallel}} nor {{forkCount}} has any effect. The debug log shows that the
plugin is switching to parallel mode, but then it runs them serially in a
single Java process. As these are browser-driving tests, serial execution
drastically increases running time.
Running the tests directly from the main project tree using {{mvn
failsafe:integration-test -DforkCount=3}} forks multiple JVMs and executes the
tests in parallel.
The attached POM is the one used to execute the tests after deployment, and
which ignores parallel execution for test from the jar.
