Test execution issue: for "shared" test contexts in multithreading [SPR-8942]

[spring-projects-issues]

Alexey Semenov opened SPR-8942 and commented

There are several db aware tests.

1. *mvn* test -Dtest.thread.count=*1* - tests always passed
2. *mvn* test -Dtest.thread.count=*10* - tests sometimes failed (running tests in several threads)
3. *mvn* test -Dtest.thread.count=*10* -Pex - tests always passed (running tests in several threads, test with "inherited test context" in excluded from execution)

@DirtiesContext didn't help.
Most common reason of a test failure is inability to load entity just saved.
Reproducible for both: AbstractTestNGSpringContextTests and AbstractTransactionalTestNGSpringContextTests.
It looks like there is an issue in context loading/caching/sharing mechanism in case of multithreading execution.

Reproducible only from command line (not IDE).
spring versions: all (2.5.6 - 3.1.0.M2)
testng versions: all (5.* - 6.*)
hibernate versions: all (3.* - 4.0.0.Final)
maven versions: 2., 3.

p.s. the issue is same as #11897

Alexey Semenov,

I downloaded the attached ZIP file and ran the tests using Maven from the command-line; however, I was never able to reproduce the error.

I am therefore closing this issue; however, if you can reproduce this problem against Spring Framework 4.2, 4.3, or 5.0 (milestones), please let us know.

Thanks!

Sam
