Method Details
-
switchIncomingChannelsToInMemory
Switch the given incoming channel to in-memory. It replaces the previously used connector with the in-memory connector.This method is generally used before tests to avoid using an external broker for a specific channel. You can then retrieve the
InMemorySource
using:@Inject @Any InMemoryConnector connector; //... @Before public void setup() { InMemoryConnector.switchIncomingChannelsToInMemory("my-channel"); } // .. InMemorySource<Integer> channel = connector.source("my-channel"); channel.send(1); channel.send(2);
- Parameters:
channels
- the channels to switch, must not benull
, must not containnull
, must not contain a blank value- Returns:
- The map of properties that have been defined. The method sets the system properties, but give you this map to pass the properties around if needed.
-
switchOutgoingChannelsToInMemory
Switch the given outgoing channel to in-memory. It replaces the previously used connector with the in-memory connector.This method is generally used before tests to avoid using an external broker for a specific channel. You can then retrieve the
InMemorySink
using:@Inject @Any InMemoryConnector connector; //... @Before public void setup() { InMemoryConnector.switchOutgoingChannelsToInMemory("my-channel"); } // .. InMemorySink<Integer> channel = connector.sink("my-channel"); assertThat(channel.received()).hasSize(3).extracting(Message::getPayload).containsExactly(1, 2);
- Parameters:
channels
- the channels to switch, must not benull
, must not containnull
, must not contain a blank value- Returns:
- The map of properties that have been defined. The method sets the system properties, but give you this map to pass these properties around if needed.
-
clear
public static void clear()Switch back the channel to their original connector.This method is generally used after tests to reset the original configuration.

source
Retrieves anInMemorySource
associated to the channel namedchannel
. This channel must use the in-memory connected.The returned
InMemorySource
lets you send messages or payloads to the channel, mocking the real interactions.- Type Parameters:
T
- the type of message or payload sent to the channel- Parameters:
channel
- the name of the channel, must not benull
- Returns:
- the source
- Throws:
IllegalArgumentException
- if the channel name isnull
or if the channel is not associated with the in-memory connector.- See Also:
-
sink
Retrieves anInMemorySink
associated to the channel namedchannel
. This channel must use the in-memory connected.The returned
InMemorySink
lets you checks the messages sent to the channel.- Type Parameters:
T
- the type of payload received by the channel- Parameters:
channel
- the name of the channel, must not benull
- Returns:
- the sink
- Throws:
IllegalArgumentException
- if the channel name isnull
or if the channel is not associated with the in-memory connector.- See Also:
