How to test form field validation in camunda unit testing


#1

Hi
I created a diagram which contains a start event - userTask (two userTasks) - end event .
In the second userTask i have a boolean form .
I want to if i put “true” in the test unit , process will be finished .
And if i put “false” in the test unit , process will be returned to first userTask.
this is my bpmn file :

and this is my test class file :

FinalTest.txt (1.2 KB)

public class FinalTest {
	@Rule
	public ProcessEngineRule rule = new ProcessEngineRule();

	@Test
	@Deployment(resources = { "BudgetDeclaration.bpmn" })
	public void executeProcess() {
		ProcessInstance processInstance = runtimeService().startProcessInstanceByKey("BudgetDeclaration");

		assertThat(processInstance).isActive();
		assertThat(processInstanceQuery().count()).isEqualTo(1);

		assertThat(processInstance).task("task1");
		assertThat(task(processInstance)).isNotNull();
		complete(task(processInstance));

		assertThat(processInstance).task("task2");
		assertThat(task(processInstance)).isNotNull();
		complete(task(processInstance));

		assertThat(processInstance).isEnded();

	}
}

Where is the form section in eclipse?

please help me !


#3

You can use an exclusive gateway to evaluate your input.
https://docs.camunda.org/manual/7.6/reference/bpmn20/gateways/exclusive-gateway/


#5

The first diagram you send has a form attached to it. By submitting data to this form, you create new task variables. The exclusive gateway can check these variables and guide the process flow based on that. (e.g. back to the first user task)

@Miklas

which command i can use to test condition in my unit test ?


#7

when i run my test class ,
this error is shown :

org.camunda.bpm.engine.ProcessEngineException: Unknown property used in expression: ${prc_ok==false}. Cause: Cannot resolve identifier 'prc_ok'

#8

There isn’t any helpful guide for my problem ??


#9

I solved my problem with this command :

 		complete(task(processInstance), withVariables("prc_ok", true));
