These kind of tests require firing up a whole cluster of nodes, before the tests can actually be run. Compared to unit tests they are obviously way more time consuming, but the test infrastructure tries to minimize the time cost by only restarting the whole cluster, if this is configured explicitly.

+==== Number of shards
The number of shards used for indices created during integration tests is randomized between `1` and `10` unless overwritten upon index creation via index settings.
The rule of thumb is not to specify the number of shards unless needed, so that each test will use a different one all the time. Alternatively you can override the `numberOfShards()` method. The same applies to the `numberOfReplicas()` method.
