Subject [jira] [Commented] (SUREFIRE-1255) Surefire 2.19.1 hangs before starting test execution
Date Wed, 02 May 2018 06:15:00 GMT

    [ https://issues.apache.org/jira/browse/SUREFIRE-1255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16460567#comment-16460567
] 

Abel Salgado Romero commented on SUREFIRE-1255:
-----------------------------------------------

I already run some isolation back when we found it doing a general upgrade: https://github.com/asciidoctor/asciidoctor-maven-plugin/pull/337.
If you want to reproduce it, just download the project from the repo https://github.com/asciidoctor/asciidoctor-maven-plugin/,
upgrade the surefire version https://github.com/asciidoctor/asciidoctor-maven-plugin/blob/master/pom.xml#L346
and run the tests.
I honestly don't discard the issue is caused by some combination of factors, but so far this
is the only lead I found :%.

Note: the first test starts an embedded server and that can be missleading, add an {{@Ignore}}
if you prefer to see the issue with a normal test.

> Seeing the same error as SUREFIRE-1193 in Apache Flink builds after upgrading from 2.18.1
to 2.19.1. No errors, builds just gets stuck at the beginning of tests with no log output
from the test itself, e.g. https://s3.amazonaws.com/archive.travis-ci.org/jobs/137118454/log.txt
> After a couple of minutes Surefire reports

> We have a a couple of test classes that suffer from this problem. Tests don't read from
STDIN or replace it. Switching back to 2.18.1 eliminates the problem (Ran over 100 builds).
It seems to be a race condition because it only occurs every once in a while, i.e. ~ 2 out
of 10 builds on Travis. I haven't been able to reproduce the problem locally.
