> ParallelComputerBuilderTest fails on overloaded system because internal delay
> are shorter than blocking time of JVM
> -------------------------------------------------------------------------------------------------------------------
>
> Key: SUREFIRE-1487
> URL: https://issues.apache.org/jira/browse/SUREFIRE-1487
> Project: Maven Surefire
> Issue Type: Task
> Components: Junit 4.7+ (parallel) support
> Reporter: Tibor Digana
> Assignee: Tibor Digana
> Priority: Major
> Fix For: 3.0.0-M1
>
>
> The delays are 500 ms and variations 250 ms.
> The JVM was blocked for 675 ms.
> From these measurements, the new delay should be 3-times longer at least.
> [windows] Tests in error:
> [windows]
> separatePoolsWithSuiteAndSequentialClasses(org.apache.maven.surefire.junitcore.pc.ParallelComputerBuilderTest):
> (..)
> [windows]
> parallelMethodsReuseOneOrTwoThreads(org.apache.maven.surefire.junitcore.pc.ParallelComputerBuilderTest):
> (..)
> [windows]
> suiteAndClassInOnePool(org.apache.maven.surefire.junitcore.pc.ParallelComputerBuilderTest):
> (..)
> suiteAndClassInOnePool:
> Expected: (between <1450L> and <1750L> or between <1950L> and <2250L> or
> between <2450L> and <2750L>)
> but: was <3175L>
> parallelMethodsReuseOneOrTwoThreads:
> Expected: between <1450L> and <1750L>
> but: was <1837L>
> separatePoolsWithSuiteAndSequentialClasses:
> Expected: between <1450L> and <1750L>
> but: was <3562L>
> In this case the JVM was blocked for 2.062 second and the delays should be 9
> times longer. The test {{ParallelComputerBuilderTest}} has small number of
> tests, so we can prolong the delays 10 times.
