Julien Herr commented on SUREFIRE-1300: --------------------------------------- I don't know but it is the default behavior for a while. But surefire is setting the good value when surefire-testng is used alone. I suppose surefire-junit is overridding things. > threadCount is 0 when surefire-junit47 and surefire-testng are used together > ---------------------------------------------------------------------------- > > Key: SUREFIRE-1300 > URL: https://issues.apache.org/jira/browse/SUREFIRE-1300 > Project: Maven Surefire > Issue Type: Bug > Components: Junit 4.x support, TestNG support > Reporter: Julien Herr > Priority: Minor > > Initial discussion: > https://github.com/easymock/easymock/pull/186#discussion_r85655490 > Sample on: https://gist.github.com/juherr/6eb3e93e2db33979b7e90b63ddadc888 > Workaround: Force `<threadCount>1</threadCount>` in surefire configuration -- This message was sent by Atlassian JIRA (v6.3.4#6332)
