Interface through which different implementations make themselves available for use by this integration test suite.
public interface MicroKernelFixture {

Checks whether this fixture is currently available. For example a database-based fixture would only be available when the underlying database service is running.

true iff the fixture is available
    boolean isAvailable();

Creates a new cluster with as many nodes as the given array has elements. References to the cluster nodes are stored in the given array. The initial state of the cluster consists of just an empty root node and a shared journal with only a single root revision. The caller of this method should have exclusive access to the created cluster. The caller is also responsible for calling tearDownCluster([]) when the test cluster is no longer needed.

cluster array to which references to all nodes of the created cluster should be stored
java.lang.Exception if the cluster could not be set up
    void setUpCluster(MicroKernel[] clusterthrows Exception;

Ensures that all content changes seen by one of the given cluster nodes are seen also by all the other given nodes. Used to help testing features like eventual consistency where the standard API doesn't make strong enough guarantees to enable writing a test case without a potentially unbounded wait for changes to propagate across the cluster.

nodes cluster nodes to be synchronized
    void syncMicroKernelCluster(MicroKernel... nodes);

Releases resources associated with the given cluster. The caller of setUpCluster([]) shall call this method once the cluster is no longer needed.

cluster array containing references to all nodes of the cluster
    void tearDownCluster(MicroKernel[] cluster);
