如何通过maven-failsafe-plugin运行基于spring-boot的应用程序的集成测试？

Question

我有一个基于spring-boot的应用程序，并且pom.xml文件的配置如下。

<?xml version="1.0" encoding="UTF-8"?> 
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 
    <modelVersion>4.0.0</modelVersion> 

    <groupId>com.example</groupId> 
    <artifactId>demo</artifactId> 
    <version>0.0.1-SNAPSHOT</version> 
    <packaging>jar</packaging> 

    <name>demo</name> 
    <description>Demo project for Spring Boot</description> 

    <parent> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-parent</artifactId> 
     <version>1.5.7.RELEASE</version> 
     <relativePath/> <!-- lookup parent from repository --> 
    </parent> 

    <properties> 
     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 
     <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> 
     <java.version>1.8</java.version> 
    </properties> 

    <dependencies> 
     <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-web</artifactId> 
     </dependency> 

     <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-test</artifactId> 
      <scope>test</scope> 
     </dependency> 
    </dependencies> 

    <build> 
     <plugins> 
      <plugin> 
       <groupId>org.springframework.boot</groupId> 
       <artifactId>spring-boot-maven-plugin</artifactId> 
       <configuration> 
        <classifier>exec</classifier> 
       </configuration> 
      </plugin> 
      <plugin> 
       <groupId>org.apache.maven.plugins</groupId> 
       <artifactId>maven-failsafe-plugin</artifactId> 
       <version>2.20.1</version> 
       <configuration> 
        <includes> 
         <include>**/IT*.java</include> 
         <include>**/*IT.java</include> 
         <include>**/*ITCase.java</include> 
        </includes> 
       </configuration> 
       <executions> 
        <execution> 
         <goals> 
          <goal>integration-test</goal> 
          <goal>verify</goal> 
         </goals> 
        </execution> 
       </executions> 
      </plugin> 
     </plugins> 
    </build> 


</project> 

的main方法位于DemoApplication类，如下称为DemoIT如下

package com.example.demo; 

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 

@SpringBootApplication 
public class DemoApplication { 

    public static void main(String[] args) { 
     System.out.println("This is a demo application+++++++++++++++++++"); 
     SpringApplication.run(DemoApplication.class, args); 
    } 
} 

我的集成测试类。

package com.example.demo; 

import org.junit.Test; 

public class DemoIT { 

    @Test 
    public void test() { 
     System.out.println("This is a integration test.=============="); 
    } 
} 

现在，这里是我的问题，当我发出命令mvn clean verify，集成类DemoIT应该被执行，它的作用。但是，我的DemoApplication未运行。所以我想知道如果我的集成测试需要在spring-boot应用程序上下文（DemoApplication需要运行）下执行，我应该怎么做才能实现？

Answer 1

由于我的应用程序是基于弹簧引导，并spring-boot-maven-plugin包括在pom.xml，所以我需要做的是添加下面的配置，以确保我们的春天启动应用程序的生命周期良好围绕管理。

<executions> 
    <execution> 
    <id>pre-integration-test</id> 
    <goals> 
     <goal>start</goal> 
    </goals> 
    </execution> 
    <execution> 
    <id>post-integration-test</id> 
    <goals> 
     <goal>stop</goal> 
    </goals> 
    </execution> 
</executions> 

后来，当我发出mvn clean verify，弹簧启动的应用程序将与我们的集成测试代码运行。
