[SUREFIRE-1487] ParallelComputerBuilderTest fails on overloaded system because internal delay are shorter than blocking time of JVM

• Type: Task
• Status: Closed
• Priority: Major
• Resolution: Fixed
• Fix Version/s: 2.22.0
• Component/s: Junit 4.7+ (parallel) support

Description

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.
