Activiti单元测试

前提：使用Maven进行依赖管理

一、如果没有，则创建文件夹：

src/test/java

src/test/resources

二、在test/resources加入配置文件activiti.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="processEngineConfiguration"
class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
<property name="jdbcUrl" value="jdbc:h2:mem:activiti;DB_CLOSE_DELAY=1000" />
<property name="jdbcDriver" value="org.h2.Driver" />
<property name="jdbcUsername" value="sa" />
<property name="jdbcPassword" value="" />
<property name="databaseSchemaUpdate" value="drop-create" />
<property name="jobExecutorActivate" value="false" />
<property name="mailServerPort" value="5025" />
<property name="history" value="full" />
</bean>
</beans>

复制代码

三、测试类及流程文件

1、测试类

import org.activiti.engine.impl.test.PluggableActivitiTestCase;
import org.activiti.engine.test.Deployment;
public class OneJobTest extends PluggableActivitiTestCase {
@Deployment
public void testTask() {
try {
runtimeService.startProcessInstanceByKey("testOneJobProcess");
fail();
} catch (Throwable e) {
assertTrue(e instanceof NullPointerException);
}
}

复制代码

import org.activiti.engine.delegate.JavaDelegate;
import org.activiti.engine.delegate.DelegateExecution;
public class TestOneJobDelegate implements JavaDelegate {
public void execute(DelegateExecution execution) {
String s = null;
System.out.println(s.toString());
}
}

复制代码

2、流程文件OneJobTest.testTask.bpmn20.xml

放在resources中于测试类同样的目录层次中。

命名规则为测试类名.方法名.bpmn20.xml。

<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:activiti="http://activiti.org/bpmn" xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI" xmlns:omgdc="http://www.omg.org/spec/DD/20100524/DC" xmlns:omgdi="http://www.omg.org/spec/DD/20100524/DI" typeLanguage="http://www.w3.org/2001/XMLSchema" expressionLanguage="http://www.w3.org/1999/XPath" targetNamespace="Examples">

</bpmndi:BPMNEdge>
</bpmndi:BPMNPlane>
</bpmndi:BPMNDiagram>
</definitions>

四、引入依赖的jar包

<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.10</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.3.170</version>
<scope>test</scope>
</dependency>

复制代码

OK，设置完毕。

附：

遇到的问题及解决办法：

1、[main] ERROR o.a.e.i.c.ProcessEngineConfigurationImpl - Exception while initializing Database connection
java.sql.SQLException: Error setting driver on UnpooledDataSource. Cause: java.lang.ClassNotFoundException: org.h2.Driver
解决办法：添加jar

<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.3.170</version>
<scope>test</scope>
</dependency>

复制代码

2、eclipse maven报错：An error occurred while filtering resources 解决办法：点击Maven -> Update Projectj即可解决问题

3、运行junit后，报：java.lang.ClassNotFoundException解决办法：使用eclise做为ide,则要正确的设置web deploy assembly.
