解决办法：

添加注解：@EnableAutoConfiguration(exclude=SecurityAutoConfiguration.class)

package com.example.demo;
import org.activiti.engine.ProcessEngines;
import org.activiti.spring.boot.SecurityAutoConfiguration;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest
@EnableAutoConfiguration(exclude=SecurityAutoConfiguration.class)
public class ActivitiSpringbootApplicationTests {
	@Test
	public void contextLoads() {
		ProcessEngines.getDefaultProcessEngine();

				3. 单元测试
单元测试在日常项目开发中必不可少，目前流行的有 JUnit 或 TestNG等测试框架。Spring Boot封装了单元测试组件spring-boot-starter-test。
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
				一、版本差异
Spring Boot 2.2.0 版本开始引入 JUnit 5 作为单元测试默认库，在 Spring Boot 2.2.0 版本之前，spring-boot-starter-test 包含了 JUnit 4 的依赖，Spring Boot 2.2.0 版本之后替换成了 Junit Jupiter。
pom.xml
    <dependency>
            <groupId>org.springframework.boot</groupId&g
				今天碰到一个问题，写测试类的时候，与项目中的某个bean有冲突，必须排除。
那么我们在使用 spring boot test 写测试类的时候，怎么去排除指定的bean呢？
假如项目中有一个StudentBean
@Component
public class StudentBean {
    private static final AppLogger logger = AppLoggerFactory.getLogger(StudentBean.class);
    @PostCo.
				一、Spring Boot Test介绍
Spring Test与JUnit等其他测试框架结合起来，提供了便捷高效的测试手段。而Spring Boot Test 是在Spring Test之上的再次封装，增加了切片测试，增强了mock能力。
整体上，Spring Boot Test支持的测试种类，大致可以分为如下三类：
单元测试：一般面向方法，编写一般业务代码时，测试成本较大。涉及到的注解有@Test。
	切片测试：一般面向难于测试的边界功能，介于单元测试和功能测试之间。涉及到的注解有@RunWith
在整个系统的高度。
一般我们测试的模块就是整个系统的启动模块：
@SpringBootApplication(exclude = DruidDataSourceAutoConfigure.class)
public class App {
    public static void main(String[] args) {
        SpringApplicationBuilde
