Common Test specific layer on Erlang/OTP rpc.

Summary

Functions

From a set of candidate nodes determines which of them is running the application App. If none of the candidate nodes is running App, the function makes the test case calling this function to fail. This function is the same as calling app_node(App, Candidates, true).

app_node(App, Candidates, FailOnBadRPC)

Same as ct_rpc:app_node/2, except that argument FailOnBadRPC determines if the search for a candidate node is to stop if badrpc is received at some point.

app_node(App, Candidates, FailOnBadRPC, Cookie)

Same as ct_rpc:app_node/2, except that argument FailOnBadRPC determines if the search for a candidate node is to stop if badrpc is received at some point.

call(Node, Module, Function, Args)

Equivalent to call(Node, Module, Function, Args, infinity, []).

call(Node, Module, Function, Args, TimeOut)

Evaluates apply(Module, Function, Args) on the node Node. Returns either whatever Function returns, or {badrpc, Reason} if the remote procedure call fails. If Node is {Fun, FunArgs}, applying Fun to FunArgs is to return a node name.

call(Node, Module, Function, Args, TimeOut, Cookie)

cast(Node, Module, Function, Args)

Evaluates apply(Module, Function, Args) on the node Node. No response is delivered and the process that makes the call is not suspended until the evaluation is completed as in the case of call/3,4. If Node is {Fun, FunArgs}, applying Fun to FunArgs is to return a node name.

Functions

app_node(App, Candidates)

-spec app_node(App, Candidates) -> CandidateNode
                  when App :: atom(), Candidates :: [node()], CandidateNode :: node().

app_node(App, Candidates, FailOnBadRPC)

-spec app_node(App, Candidates, FailOnBadRPC) -> CandidateNode
                  when
                      App :: atom(),
                      Candidates :: [node()],
                      FailOnBadRPC :: boolean(),
                      CandidateNode :: node().

Same as ct_rpc:app_node/2, except that argument FailOnBadRPC determines if the search for a candidate node is to stop if badrpc is received at some point.

app_node(App, Candidates, FailOnBadRPC, Cookie)

-spec app_node(App, Candidates, FailOnBadRPC, Cookie) -> CandidateNode
                  when
                      App :: atom(),
                      Candidates :: [node()],

                      Cookie :: atom() | [],
                      CandidateNode :: node().

Same as ct_rpc:app_node/2, except that argument FailOnBadRPC determines if the search for a candidate node is to stop if badrpc is received at some point.

The cookie on the client node is set to Cookie for this rpc operation (used to match the server node cookie).

call(Node, Module, Function, Args)

-spec call(Node, Module, Function, Args) -> term() | {badrpc, Reason}
              when
                  Node :: {Function, Args} | node(),
                  Module :: module(),
                  Function :: atom(),
                  Args :: list(),
                  Reason :: term().

Equivalent to call(Node, Module, Function, Args, infinity, []).

call(Node, Module, Function, Args, TimeOut)

-spec call(Node, Module, Function, Args, TimeOut) -> term() | {badrpc, Reason}
              when
                  Node :: {Function, Args} | node(),
                  Module :: module(),

                  Args :: list(),
                  TimeOut :: timeout(),
                  Reason :: term().

call(Node, Module, Function, Args, TimeOut, Cookie)

-spec call(Node, Module, Function, Args, TimeOut, Cookie) -> term() | {badrpc, Reason}
              when
                  Node :: {Function, Args} | node(),
                  Module :: module(),
                  Function :: atom(),
                  Args :: list(),
                  TimeOut :: timeout(),
                  Cookie :: atom() | [],
                  Reason :: term().

The cookie on the client node is set to Cookie for this rpc operation (used to match the server node cookie).

cast(Node, Module, Function, Args)

-spec cast(Node, Module, Function, Args) -> ok
              when
                  Node :: {Function, Args} | node(),

                  Node :: {Function, Args} | node(),
                  Module :: module(),
                  Function :: atom(),
                  Args :: list(),
                  Cookie :: atom() | [].

The cookie on the client node is set to Cookie for this rpc operation (used to match the server node cookie).
