[GitHub] jmeter pull request #350: Parallelised unit tests

[ham1]

GitHub user ham1 opened a pull request:

Parallelised unit tests

## Description

introduced `JMeterSerialTest` interface for tests which need to be run in 
sequence not concurrently.
Re-wrote `TestFileServer` in Spock to use private constructor to get around 
singleton and make clearer to understand.
Added a test listener to time and log to file time taken for each unit test.
Also refactored/re-formatted some code while investigating parallel test 
failures.

`ant _test` time on a 4 core laptop:
before: 1m 19s
after:  51s

on an 8 core PC:
before: 59s
after:  31s

I'd welcome more testing on different configurations and review.

## Motivation and Context

Speed up feedback

## How Has This Been Tested?

100 iterations of `ant _test` on an 8 core machine
50 iterations of `ant _test` on a 4 core machine

## Screenshots (if appropriate):

Parallelised unit tests.
Introduced JMeterSerialTest interface for tests which need to be run
individually in sequence not concurrently.

singleton.
Also refactored/re-formatted some code while investigating parallel test 
failures.
