今天我們要來對Camunda流程進行功能性測試，廢話不多說，我們直接開始。

UT測試

Unit Test（UT）用於驗證單一程式碼單元的正確性，Java中，JUnit是最常用的單元測試框架，可以幫助開發人員編寫和運行測試案例。

確定測試範圍

我們針對流程分之進行測試，通過分析流程，我們只需分析幾個分支：

1. 檢查資料完整性，有兩個分支。

編寫測試代碼

我們透過IDEA中的TEST生成功能幫我們生成一個模板進行測試，我們首先要切換到「Form_IntegrityCheck」。

點擊右鍵，選擇「Generate」。

點選Generate > Test

我們就可以看到，勾選要測試的方法，點選 OK。

接著我們將Junit加入到pom.xml，透過IDEA的提示完成。

失敗的測試(不要使用)

筆者對Junit不熟，試了一整天還是無法啟動，跟大家說聲抱歉，不過我還是把失敗的程式碼放到文章中，避免大家踩坑。

Form_IntegrityCheck.java

package com.example.form_IntegrityCheck;
import org.camunda.bpm.scenario.ProcessScenario;
import org.camunda.bpm.scenario.Scenario;
import org.camunda.bpm.engine.test.Deployment;
import org.camunda.bpm.engine.variable.Variables;
import org.camunda.bpm.scenario.run.ProcessRunner;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mock;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import static org.mockito.Mockito.verify;

import java.util.Map;

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.NONE)
public class Form_IntegrityCheckTest {
    private static final String PROCESS_DEFINITION_KEY = "test";

    private Map<String, Object> variables;

    @Mock
    private ProcessScenario myProcess;

    @Test
    @Deployment(resources = "main.bpmn")
    public void testNeedMoreDocuments() {
        variables = Variables.createVariables();
        variables.put("id", "id");
//    variables.put("name", "name");

        ProcessRunner.ExecutableRunner starter = Scenario.run(myProcess).startByKey(PROCESS_DEFINITION_KEY, variables);

        // OK - everything prepared - let's go and execute the scenario
        Scenario scenario = starter.execute();

        // now you can do some assertions
        verify(myProcess).hasFinished("EndEvent_NeedMoreDocument");
    }

}
