Providing a unit test

[Daniel Meyer]

Hi All,

Sometimes you discover bugs in the process engine or you notice a behavior where you are not sure whether it is expected or not. 

Such situations are often surprisingly hard to describe in plain language but can be communicated in code much more accurately.

In such situations we will ask you to provide a unit test demonstrating the behavior you want to discuss. 

In order to make it easier for you to provide a unit test we created a simple project template which you can use and adapt:

https://github.com/camunda/camunda-engine-unittest

Thank you all for your many valuable contributions to the camunda community!

Cheers,

Daniel Meyer

Thanks a lot! I'll do so next time!

[Peter Metz]

Hello Daniel, 

thanks for your hint :-)

I'll try this to find the reason for a strange behaviour: deploying a model with eclipse Kepler x86 32bit version + maven + camunda works fine. Same thing but using an eclipse Kepler x64 64bit does not work. But there are NO ERR message, nothing. The model just does not appear in the camunda cockpit. (Apache Tomcat/7.0.54 1.7.0_60-b19 Oracle Corporation Windows Server 2008 R2 6.1 amd64)

Best Regards, Peter

Hi Daniel,

The POM for the unit test example needs updating to include:

<groupId>org.camunda.bpm.extension</groupId>
<artifactId>camunda-bpm-assert</artifactId>
<version>1.1</version>

rather than

<groupId>org.camunda.bpm.extension</groupId>
<artifactId>camunda-bpm-assert</artifactId>
<version>1.0</version>

1.0 is no longer hosted.

Kind Regards

Gareth

Hi Gareth,

thanks, we'll look into it. I think Martin already prepared a Pull
Request, we'll just need to merge it :)

Hi,

I was able to get this unit test framework to run, and execute a process I created.
However, as soon as I add

camunda:async="true"

to a task, the process seems to stall out. I think this might have something to do with the way this framework is setup with the H2 database, but I'm not sure.

I've setup two unit tests. Each of them are exactly the same except one has the script task marked as async, and the other doesn't.

++++++++++

Get and compile unit test:
git clone https://github.com/druid77/camunda_locking_parallel_gateway_unit_test.git
cd camunda_locking_parallel_gateway_unit_test
mvn clean compile

To run with async script task:
mvn -Dtest=SimpleTestCase#simpleNoAsync test

To run with no async script task:
mvn -Dtest=SimpleTestCase#simpleNoAsync test


As you can see, the process with async doesn't complete (prints out "IS ENDED: false").
Am I doing something wrong here?
In another test, I tried this with a serviceTask (using a JavaDelegate), and it also stalled out...

Any ideas?

Thanks,
Galen

I made a typo in my post - The first test was supposed to say:

mvn -Dtest=SimpleTestCase#simpleWithAsync test

Hi Galen,

For better testability, the job executor is deactivated in the engine configuration in the testing template. In unit tests, it is often easier to manually trigger job execution by using the ManagementService. If you want to activate the job executor anyway, make sure to change the following line in camunda.cfg.xml:

<property name="jobExecutorActivate" value="false" />

to the value "true".

Cheers,
Thorben

[galen...@gmail.com]

Thanks, this makes sense why it was stalling now. I enabled that property, and now the process executes as expected!

Hello,

I am new in the camunda area.
I am currently trying out to test a process via Unit Testing.
I found this example (1) http://docs.camunda.org/7.2/guides/user-guide/#testing-unit-testing and the project example you were talking about in this forum (2) https://github.com/camunda/camunda-engine-unittest.

1.question:
In example (1), I don't what and how I have to configure, that the library with the 'RuntimeService' and the 'TaskService' are included in my project.

2.question:
Do you have suggestion with literatures or links that helps me to learn more about unit testing of BPMN2.0 processes that helps me to find out its range of possibilities.

Thank you in advance !

[Sebastian Menski]

Hi Kirsten,

1. If your test class extends ProcessEngineTestCase the process engine services (runtimeService, taskService etc.) will be initialized

2. You could have a look at bpm assert [1] which is a greate library for testing bpm processes. Checkout the user guide for more informations [2].

Cheers,

Sebastian

Hi Sebastian,

I'm trying to use DMN in my BPMN process.

I changed the unittest project below to include and use my BPMN.

https://github.com/camunda/camunda-engine-unittest

Unfortunately I get the following error. I don't know why. Do you have any idea what is missing?

Hi Tamas,

the exception states that you try to call a decision with the id 'bookingStrands'. And it doesn't find a deployed decision with this id. Are you

sure the decision is deployed correctly?

Cheers,

Sebastian

[Matányi Tamás]

Hi Sebastian,

 

We’re talking about unitTesting. Do you mean .startProcessInstance on deploy?

 

ProcessInstance processInstance = runtimeService().startProcessInstanceByKey(”ID”);

 

Yes, you’re right. I didn’t deployed decision with the ID 'bookingStrands' Should I do it?

The missing file is just beside the started BPMN in src/test/resources.

 

I’m afraid I don’t know how to deploy DMN in a unitTest.

 

Thanks in advance,

Tamas

no problem. Camunda provides a @Deployment test annotation which allows you to easily deploy resources need for the unit test. As you can see

in our example [1] we used it to deploy the "testProcess.bpmn" file which is used by the unit test. If you want to deploy more resources needed

by your unit test just add them to the resources list like so (assuming your DMN file is called 'decision.dmn'):

@Test
@Deployment(resources = {"testProcess.bpmn", "decision.dmn"})
public void shouldExecuteProcess() {
  // ... test code ...
}

There is also a small section about unit testing in our docs [2].

Cheers,

Sebastian

Hi,

 

I don’t understand why I get the following error on running my unit test:

 

SEVERE: Error while closing command context

org.camunda.bpm.engine.ProcessEngineException: One of the attributes 'class', 'delegateExpression', 'type', or 'expression' is mandatory on

businessRuleTask. | BookingEngineDMN.bpmn | line 45 | column 205

One of the attributes 'class', 'delegateExpression', 'type', or 'expression' is mandatory on businessRuleTask. | BookingEngineDMN.bpmn | lin

e 67 | column 231

 

Why these attributes are mandatory (class, delegateExpression, type, expression) on businessRuleTask?

 

I have this line in my BPMN:

<businessRuleTask id="sid-40AAB0E8-AEAE-494D-ABC6-6DD6F6D99922" camunda:decisionRef="bookingStrands" camunda:resultVariable="unterkonto" name="BookingStrand ermitteln" implementation="##WebService">

It has a camunda:decisionRef attribute reffering to the appropriate DMN. What else is missing?

 

Thanks in advance,

Tamas

Hi Tamas,

which version of Camunda are you using? The decisionRef attribute will be introduced with the next 7.4.0 release. The example provided at [1] is

using Camunda version 7.3.0 so the "decisionRef" attribute is not known.

You could change the version in the pom.xml to 7.4.0-alpha3 and it should work.

Cheers

Sebastian

Hi Sebastian,

Unfortunately it says:

Hi Tamas,

I tried it myself. Please ensure that your IDE updates the artifacts correctly. I run the following maven command at it worked as expected:

mvn clean test

As you can see the artifact [1] is available on maven central.

Cheers,

Hi Sebastian,

I could get the version (7.4.0-alpha3) we need finally.

Now, I get the following error:

Hi Tamas,

with alpha3 we switchted to DMN 1.1. The file you posted is still DMN 1.0. You now have to options. Either you remodel

your decision with the online modeler [1] to get DMN 1.1 XML. Or you use the 7.4.0-alpha2 of Camunda which still

uses DMN 1.0.

I would recommend the switch to DMN 1.1 as this will be part of the final release.

Cheers,
Sebastian

Hi Sebastian,

Seems it's not working even with alpha3 version. I tried with both alpha2 & alpha3 versions, but not able to deploy and getting errors. 

Created the DMN file with Camunde Modeler and online tool provided, still same issue. How to differentiate DMN1.1 DMN1.0 files, because it looks same for me. 

POM

<properties>

   <camunda.version>7.4.0</camunda.version>

   <spring.version>3.1.2.RELEASE</spring.version>

Here is the Error LOG, If I use alpha3 in POM

SEVERE [org.camunda.bpm.engine.impl.interceptor.CommandContext] (Se

rverService Thread Pool -- 82) Error while closing command context: org.camunda.

bpm.engine.ProcessEngineException: Unable to transform DMN resource 'My-Dish-Dec

Thanks in advance.

Hi,

please use the final release 7.4.0. You can see which version of DMN you are using by the namespace of the XML file.

DMN 1.1 has the following namespace

<definitions xmlns="http://www.omg.org/spec/DMN/20151101/dmn11.xsd" ...

Cheers,

Sebastian

[VENKATARAJU NANDAM]

Hi Sebastian,

Yes, am able to see (.dmn11.xsd) in the updated file with online link. I moved to camunda-bpm-jboss-7.5.0-alpha2 version and its working well. 

Thanks,

VenkataRaju
