prasanthkumar2392 commented on issue #6642: Context in Pulsar functions not getting mocked
URL: https://github.com/apache/pulsar/issues/6642#issuecomment-608241467
Hi,
- I am using functions api 2.5.0 and I am using context to set the key and value inside functions and sending it to the output topic.
- But in my test class, I am trying to mock the context and i am unsuccesfull.
(Also tried context configuration of puslar test container to see if context is not null)
My function class to process the messages
`
import org.apache.pulsar.client.api.PulsarClientException;
import org.apache.pulsar.client.api.Schema;
import org.apache.pulsar.functions.api.Context;
import org.apache.pulsar.functions.api.Function;
import org.slf4j.Logger;
public class MyFunction implements Function<byte[], Void> {
@Override
public Void process(byte[] input, Context context) throws Exception {
Logger log = context.getLogger();
log.debug("Entered ");
//Initialize Required classes to process message
if (input != null) {
try {
// assign the key and value and send it to output topic
log.debug("Key :");
log.debug("Value ");
context.newOutputMessage(context.getOutputTopic(), Schema.STRING)
.key("")
.value("")
.send();
} catch (PulsarClientException e) {
log.error("error in " + e.toString());
}
}
return null;
}
}
`
and my sample test class
`import com.ericsson.iota.dm.function.MyFunction;
import org.apache.pulsar.functions.api.Context;
import org.junit.jupiter.api.Test;
import static org.mockito.Mockito.mock;
public class FunctionTest {
@Test
public void functionProcessing() throws Exception {
String message ="{\n" +
" \"name\": \"XXXXX\",\n" +
" \"email\": \"xxxxx@xxx.com\"\n" +
"}";
MyFunction myFunction =new MyFunction();
myFunction.process(message.getBytes(), mock(Context.class));
// Assert conditions
}
}
`
