Junit测试异常事件触发

下面的示例中测试在程序中触发异常事件的流程，流程如下

测试程序

public void testTimerBoundaryEventInterrupting() throws Exception {
        KnowledgeBase kbase = createKnowledgeBase("BPMN2-TimerBoundaryEventInterrupting.bpmn2");
        StatefulKnowledgeSession ksession = createKnowledgeSession(kbase);
        ksession.getWorkItemManager().registerWorkItemHandler("MyTask",
                new DoNothingWorkItemHandler());
        ProcessInstance processInstance = ksession
                .startProcess("TimerBoundaryEvent");
        assertTrue(processInstance.getState() == ProcessInstance.STATE_ACTIVE);
        Thread.sleep(1000);
        ksession = restoreSession(ksession, true);
        System.out.println("Firing timer");
        ksession.fireAllRules();
        assertProcessInstanceCompleted(processInstance.getId(), ksession);
    }

结果如下

Loading process BPMN2-TimerBoundaryEventInterrupting.bpmn2
Timer handled
Firing timer

Junit测试根据规则执行子流程

下面的示例中测试在程序中加入固定规则，然后如果发现符合规则那么向下执行子流程

流程界面如下

规则文件如下

package org.drools.bpmn2
 
import org.drools.runtime.process.ProcessContext
 
rule "Auto-activate Hello1" ruleflow-group "Hello"
  when
  then
    System.out.println(drools);
    System.out.println(drools.getContext(ProcessContext.class));
    System.out.println(drools.getContext(ProcessContext.class).getProcessInstance());
    drools.getContext(ProcessContext.class).getProcessInstance().signalEvent("Hello1", null);
end

测试程序

public void testAdHocSubProcess() throws Exception {
        System.out.println("Loading process BPMN2-AdHocSubProcess.bpmn2");
        KnowledgeBuilder kbuilder = KnowledgeBuilderFactory
                .newKnowledgeBuilder();
        kbuilder.add(ResourceFactory
                .newClassPathResource("junit/BPMN2-AdHocSubProcess.bpmn2"),
                ResourceType.BPMN2);
        kbuilder.add(ResourceFactory
                .newClassPathResource("junit/BPMN2-AdHocSubProcess.drl"),
                ResourceType.DRL);
        KnowledgeBase kbase = kbuilder.newKnowledgeBase();
        StatefulKnowledgeSession ksession = createKnowledgeSession(kbase);
        TestWorkItemHandler workItemHandler = new TestWorkItemHandler();
        ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
                workItemHandler);
        ProcessInstance processInstance = ksession
                .startProcess("AdHocSubProcess");
        assertTrue(processInstance.getState() == ProcessInstance.STATE_ACTIVE);
        WorkItem workItem = workItemHandler.getWorkItem();
        assertNull(workItem);
        ksession = restoreSession(ksession, true);
        ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
                workItemHandler);
        ksession.fireAllRules();
        System.out.println("Signaling Hello2");
        ksession.signalEvent("Hello2", null, processInstance.getId());
        workItem = workItemHandler.getWorkItem();
        assertNotNull(workItem);
        ksession = restoreSession(ksession, true);
        ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
                workItemHandler);
        ksession.getWorkItemManager().completeWorkItem(workItem.getId(), null);
    }

执行结果如下

Loading process BPMN2-AdHocSubProcess.bpmn2
org.drools.base.DefaultKnowledgeHelper@1bdb58
org.drools.spi.ProcessContext@1568654
WorkflowProcessInstance1 [processId=AdHocSubProcess,state=1]
Hello World 1
Signaling Hello2
Hello World 2
执行test workitemWorkItem 1 [name=Human Task, state=0, processInstanceId=1, parameters{}]

Junit测试根据规则执行子流程并自动完成

下面的示例中测试在程序中如下图

执行流程如下，执行完成之后自动完成并且向下走

测试程序

public void testAdHocSubProcessAutoComplete() throws Exception {
        System.out
                .println("Loading process BPMN2-AdHocSubProcessAutoComplete.bpmn2");
        KnowledgeBuilder kbuilder = KnowledgeBuilderFactory
                .newKnowledgeBuilder();
        kbuilder.add(
                ResourceFactory
                        .newClassPathResource("junit/BPMN2-AdHocSubProcessAutoComplete.bpmn2"),
                ResourceType.BPMN2);
        kbuilder.add(ResourceFactory
                .newClassPathResource("junit/BPMN2-AdHocSubProcess.drl"),
                ResourceType.DRL);
        KnowledgeBase kbase = kbuilder.newKnowledgeBase();
        StatefulKnowledgeSession ksession = createKnowledgeSession(kbase);
        TestWorkItemHandler workItemHandler = new TestWorkItemHandler();
        ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
                workItemHandler);
        ProcessInstance processInstance = ksession
                .startProcess("AdHocSubProcess");
        assertTrue(processInstance.getState() == ProcessInstance.STATE_ACTIVE);
        WorkItem workItem = workItemHandler.getWorkItem();
        assertNull(workItem);
        ksession = restoreSession(ksession, true);
        ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
                workItemHandler);
        ksession.fireAllRules();
        workItem = workItemHandler.getWorkItem();
        assertNotNull(workItem);
        ksession = restoreSession(ksession, true);
        ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
                workItemHandler);
        ksession.getWorkItemManager().completeWorkItem(workItem.getId(), null);
        assertProcessInstanceCompleted(processInstance.getId(), ksession);
    }

执行结果

Loading process BPMN2-AdHocSubProcessAutoComplete.bpmn2
org.drools.base.DefaultKnowledgeHelper@6833f2
org.drools.spi.ProcessContext@1bdb58
WorkflowProcessInstance1 [processId=AdHocSubProcess,state=1]
执行test workitemWorkItem 1 [name=Human Task, state=0, processInstanceId=1, parameters{}]

        ProcessInstance processInstance = ksession.startProcess("AdHocProcess");
        assertTrue(processInstance.getState() == ProcessInstance.STATE_ACTIVE);
        ksession = restoreSession(ksession, true);
        ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
                new DoNothingWorkItemHandler());
        System.out.println("Triggering node");
        ksession.signalEvent("Task1", null, processInstance.getId());
        assertProcessInstanceActive(processInstance.getId(), ksession);
        ksession.signalEvent("User1", null, processInstance.getId());
        assertProcessInstanceActive(processInstance.getId(), ksession);
        ksession.insert(new Person());
        ksession.signalEvent("Task3", null, processInstance.getId());

                new DoNothingWorkItemHandler());
        ProcessInstance processInstance = ksession
                .startProcess("IntermediateCatchEvent");
        assertTrue(processInstance.getState() == ProcessInstance.STATE_ACTIVE);
        // now wait for 1 second for timer to trigger
        Thread.sleep(1000);
        ksession = restoreSession(ksession, true);
        ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
                new DoNothingWorkItemHandler());
