Camunda Assert: "Could not resolve function 'S'."

pme123 · June 20, 2020, 4:53am

I want to test my BPMN with Camunda Assert in my Spring Boot Application.

So Spin seems not to be available in the Test.

It works when deploying the BPMN in the Application.

Is there something I have to configure for Camunda testing?

Here is the Stack Trace (Removing the mentioned Expression solved the problem)

Hi @pme123,

how did you set up the process engine?

Maybe you have to add the SPIN process engine plugin explicitly: https://docs.camunda.org/manual/7.13/user-guide/data-formats/configuring-spin-integration/#camunda-engine-plugin-spin

Hope this helps, Ingo

Hi @Ingo_Richtsmeier

Thanks for the help. Adding the following to test/resources/META-INF/processes.xml did not help:

<process-application
        xmlns="http://www.camunda.org/schema/1.0/ProcessApplication"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

    <process-engine name="default">

        <plugins>
            <plugin>
                <class>org.camunda.spin.plugin.impl.SpinProcessEnginePlugin</class>
            </plugin>
        </plugins>

    </process-engine>

</process-application>

Hi @pme123,

I havn’t tried it with the processes.xml. I usually add it to camunda.cfg.xml: https://docs.camunda.org/manual/7.13/user-guide/process-engine/process-engine-bootstrapping/#configure-process-engine-using-camunda-cfg-xml

<?xml version="1.0" encoding="UTF-8"?>

Hope this helps, Ingo
