FormServiceTest String cannot be cast to BigDecimal

[tomi87]

I reproduced the FormServiceTest.java from chapter 5. Then I tried to start this test with the whole loanrequest.bpmn20.xml, I imported the .jar file in the folder and added this to the librarys,  but I get this error message:

They wrote in the book "At the start of the process, these properties are converted into process variables of the correct type."
What did I wrong or what should I add ?

Hi,

Can you add the BPMN XML you used? And maybe also the test you run?

Best regards,

[tomi87]

Can you add the BPMN XML you used? And maybe also the test you run?

It's the bpmn20.xml loanrequest file from the book:
<process id="loanrequest" name="Process to handle a loan request">
  <startEvent id="theStart">
   <extensionElements>
    <activiti:formProperty id="name" name="Name"
     required="true" type="string" />
    <activiti:formProperty id="emailAddress" name="Email address"
     required="true" type="string" />
    <activiti:formProperty id="income" name="Income"
     required="true" type="long" />
    <activiti:formProperty id="loanAmount" name="Loan amount"/>
   </extensionElements>
  </startEvent>
  <sequenceFlow sourceRef="theStart" targetRef="checkCredit" />
  <scriptTask id="checkCredit" scriptFormat="groovy">
   <script>
    outrintln "Checking credit for " + name;
    creditCheckOk = false;
    if((income / 2) > loanAmount){creditCheckOk = true;}
    outrintln "Checked credit for " + name + " outcome is " + creditCheckOk;
   </script>
  </scriptTask>
  <sequenceFlow sourceRef="checkCredit" targetRef="createApplication" />
  <serviceTask id="createApplication" activiti:class="org.CreateApplicationTask" />
  <sequenceFlow sourceRef="createApplication" targetRef="theEnd" />
  <endEvent id="theEnd" />
</process>
</definitions>

Test:
public class FormServiceTest{

@Rule
public ActivitiRule activitiRule = new ActivitiRule("activiti.cfg-mem.xml");

@Test
@Deployment(resources={"loanrequest.bpmn20.xml"})
public void startFormSubmit() {
  //startFormTest
  ProcessDefinition definition = activitiRule.getRepositoryService()
    .createProcessDefinitionQuery().processDefinitionKey("loanrequest").singleResult();
  assertNotNull(definition);

  FormService formService = activitiRule.getFormService();
  List<FormProperty> formList = formService.getStartFormData(definition.getId()).getFormProperties();
  assertEquals(4, formList.size());

  Map<String, String> formProperties = new HashMap<String, String>();
  formProperties.put("name", "Miss Piggy");
  formProperties.put("emailAddress", "piggy@localhost");
  formProperties.put("income", "400");
  formProperties.put("loanAmount", "100");
  formService.submitStartFormData(definition.getId(), formProperties);

  List<HistoricDetail> historyVariables = activitiRule.getHistoryService()
         .createHistoricDetailQuery()
         .formProperties()
         .list();

  assertNotNull(historyVariables);
  assertEquals(4, historyVariables.size());

//The following test cases are maybe wrong. I fix it later.

  HistoricFormProperty formProperty = (HistoricFormProperty) historyVariables.get(0);
  assertEquals("loanAmount", formProperty.getPropertyId());
  assertEquals("100", formProperty.getPropertyValue());
 
  formProperty = (HistoricFormProperty) historyVariables.get(1);
  assertEquals("income", formProperty.getPropertyId());
  assertEquals("400", formProperty.getPropertyValue());
}
}
My plan is to create a test for the first 'startEvent', 'scriptTask id="checkCredit" ' and 'serviceTask id="createApplication" '. Where I want to set the input Variable for the startEvent and then to test, if the variables are in the created object from activiti:class="org.CreateApplicationTask".

My problem is, how can I submit the input variables that I can check if they are at the end in the object?

I would testthe variable with this kind of following test:
List<HistoricDetail> historyVariables = activitiRule.getHistoryService().createHistoricDetailQuery().variableUpdates().orderByVariableName().asc().list();
HistoricVariableUpdate loanAppUpdate = ((HistoricVariableUpdate) historyVariables.get(5));
  assertEquals("loanApplication", loanAppUpdate.getVariableName());
  LoanApplication la = (LoanApplication) loanAppUpdate.getValue();
  assertEquals(true, la.isCreditCheckOk());
Hope you can help me.

Best regards

Do you need some other information ?

[jbarrez]

Do you need some other information ?

No, it's just that I don't get what you are trying to achive:

My problem is, how can I submit the input variables that I can check if they are at the end in the object?

As I understand your original exception, it seems you are passing a String value instead of a numerical value. And that is where the script crashes.

And yes, if I check your test code, I see this:

Map<String, String> formProperties = new HashMap<String, String>();
      formProperties.put("name", "Miss Piggy");
      formProperties.put("emailAddress", "piggy@localhost");
      formProperties.put("income", "400");
      formProperties.put("loanAmount", "100");
      formService.submitStartFormData(definition.getId(), formProperties);

Which are all strings.
