public static HostPickingStrategy random()

For any given invocation returns a random host

Returns:

The strategy object

randomOneHost

public static HostPickingStrategy randomOneHost()

Pick a single host and use that for all jobs to be deployed in the tests used by this strategy. If you want multiple test classes to use the same host, share the strategy between tests as a constant.

Returns:

The strategy object

deterministic

public static HostPickingStrategy deterministic(String key)

For any given invocation returns a random host, but running the same test with the same key should put jobs on the same hosts as they were the last time.

Parameters:

key - The random generator seed

Returns:

The strategy object

deterministicOneHost

public static HostPickingStrategy deterministicOneHost(String key)

Deterministically, choose a single host for all jobs in the test. That is, it will choose the same host given equal values of key. If you want multiple test classes to use the same host, share the strategy between tests as a constant.

Parameters:

key - The random generator seed

Returns:

The strategy object
