Example 2 with DelegateExpressionCaseExecutionListener

use of org.camunda.bpm.engine.impl.cmmn.listener.DelegateExpressionCaseExecutionListener in project camunda-bpm-platform by camunda.

the class DelegateExpressionExecutionListenerSpec method verifyListener.

public void verifyListener(DelegateListener<? extends BaseDelegateExecution> listener) {
    assertTrue(listener instanceof DelegateExpressionCaseExecutionListener);
    DelegateExpressionCaseExecutionListener delegateExpressionListener = (DelegateExpressionCaseExecutionListener) listener;
    assertEquals(DELEGATE_EXPRESSION, delegateExpressionListener.getExpressionText());

        FieldSpec matchingFieldSpec = fieldSpecs.get(i);
        matchingFieldSpec.verify(declaration);
    }
