Module Summary
Common Test specific layer on Erlang/OTP rpc.
Description
Common Test
specific layer on Erlang/OTP rpc
.
Exports
app_node(App, Candidates) -> NodeName |
Types
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) -> NodeName |
Types
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) -> NodeName |
Types
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) -> term() | {badrpc, Reason} |
Same as call(Node, Module, Function, Args, infinity)
.
call(Node, Module, Function, Args, TimeOut) -> term() | {badrpc, Reason} |
Types
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) -> term() | {badrpc, Reason} |
Types
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.
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) -> ok |
Types
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.
