/**
*
* This class tests RM's mechanism of resource selection with static
* scripts.
*
* -launch nodes with a specified JVM environment variable => verify script
* -launch 5 nodes without this specified JVM environment variable => not verify script
*
* 1/ ask 1 node with a selection that check this environment variable,
* and verify that a node can be provided by RM
* 2/ ask 3 nodes with specific environment var, and check that just one node can be provided
* 3/ add a second node with specific JVM env var and ask 3 nodes with specific environment var,
* and check that two nodes can be provided with one getAtMostNodes method call.
* 4/ remove the node with specified environment var, end check that no node
* can be provided
* 5/ ask a node with a selection script that provides execution error,
* and check that error handling is correct.
* 6/ ask a node with a selection script that doesn't return
* the 'selected' return value
