sindrip / ex_unit_cluster Goto Github PK

Thank you very much for this dependency. It provides great convenience for writing cluster tests.

Can you provide an option for ExUnitCluster.start_node/2 to control the behaviour that connect to the other nodes in same cluster automatically or not? (Even do this at the very beginning of the boot process).

Example

• Scenario 1
  Test a GenServer using the handle_continue/2 initialization state by getting data from other nodes in the cluster.

Currently, a node started by ExUnitCluster.start_node/2 will first complete the startup, then connect to the existing nodes by calling ExUnitCluster.call(cluster, new_node, Node, :connect, [base_node]) manually.

So I would miss the opportunity to test the GenServer init process. What I need here is to connect to the cluster first then start the GenServer.

• Scenario 2

Test a GenServer with send sync signal periodically, especially the moment that join the cluster.

But for this one, I just want to control the connection manually.
