I have created the dmn file and test using postman, but am getting some error as mentioned below

I have given the Post request URL below
http://localhost:8080/engine-rest/decision-definition/key/Decision_12pyi3j/evaluate

Request body:
{

Hi @Junaka,

usually the root cause is given lower in the nested stacktrace:

Either you didn’t provide the variable BizData or the attribute yoshinrank is not given.

Hope this helps, Ingo

Thanks @Ingo_Richtsmeier .

@Ingo_Richtsmeier Is there any way to test the DMN efficiently using java?

If there anything please share the document with some examples.

Ingo_Richtsmeier · June 23, 2022, 8:27am

Hi @Junaka,

yes it is: Testing Decisions with the DMN Engine | docs.camunda.org

If you use the process engine, you can even write shorter tests like:

  @Test
  @Deployment(resources = {"tweet-approval.dmn"})
  public void testTweetVonJakob() {
    Map<String, Object> variables = withVariables("email", "jokob.freund@camunda.com", "content", "das hier soll veröffentlicht werden");
    DmnDecisionTableResult decisionTableResult = decisionService().evaluateDecisionTableByKey("tweetApproval", variables);
    
    assertThat(decisionTableResult.getFirstResult()).contains(entry("approved", true));
  }

The setup of the test could be done like here: Testing | docs.camunda.org

Hope this helps, Ingo
