运行集成测试

虽然您可以很容易地从测试(或测试套件)本身启动 Spring Boot 应用程序,但在构建过程中处理这一点可能是可取的。 为了确保 Spring Boot 应用程序的生命周期在集成测试周围得到适当管理,您可以使用 startstop 目标,如以下示例所示:

<build>
	<plugins>
		<plugin>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-maven-plugin</artifactId>
			<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>
		</plugin>
	</plugins>
</build>

这种设置现在可以使用 failsafe-plugin 来运行您的集成测试。

注意:应用程序在单独的进程中启动,并使用 JMX 与应用程序通信。 默认情况下,插件使用端口 9001。 如果需要配置 JMX 端口,请参阅 专用示例

您还可以配置更高级的设置,以便在设置了特定属性时跳过集成测试,请参阅 专用示例

在没有 Spring Boot 的父 POM 的情况下使用 Failsafe

Spring Boot 的父 POM,spring-boot-starter-parent,将 Failsafe 的 <classesDirectory> 配置为 ${project.build.outputDirectory}。 没有此配置,Failsafe 将使用已编译的类而不是重新打包的 jar,Failsafe 无法加载您的应用程序类。 如果您不使用父 POM,则应按以下示例所示以相同方式配置 Failsafe:

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-failsafe-plugin</artifactId>
	<configuration>
		<classesDirectory>${project.build.outputDirectory}</classesDirectory>
	</configuration>
</plugin>

spring-boot:start

org.springframework.boot:spring-boot-maven-plugin:3.4.6

Start a spring application. Contrary to the run goal, this does not block and allows other goals to operate on the application. This goal is typically used in integration test scenario where the application is started before a test suite and stopped after.

示例

集成测试的随机端口

Spring Boot 测试集成的一个不错的功能是它可以为 Web 应用程序分配一个空闲端口。 当使用插件的 start 目标时,Spring Boot 应用程序是单独启动的,因此很难将实际端口传递给集成测试本身。

下面的示例展示了如何使用 Build Helper Maven Plugin 实现相同的功能:

<build>
	<plugins>
		<plugin>
			<groupId>org.codehaus.mojo</groupId>
			<artifactId>build-helper-maven-plugin</artifactId>
			<executions>
				<execution>
					<id>reserve-tomcat-port</id>
					<goals>
						<goal>reserve-network-port</goal>
					</goals>
					<phase>process-resources</phase>
					<configuration>
						<portNames>
							<portName>tomcat.http.port</portName>
						</portNames>
					</configuration>
				</execution>
			</executions>
		</plugin>
		<plugin>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-maven-plugin</artifactId>
			<executions>
				<execution>
					<id>pre-integration-test</id>
					<goals>
						<goal>start</goal>
					</goals>
					<configuration>
						<arguments>
							<argument>--server.port=${tomcat.http.port}</argument>
						</arguments>
					</configuration>
				</execution>
				<execution>
					<id>post-integration-test</id>
					<goals>
						<goal>stop</goal>
					</goals>
				</execution>
			</executions>
		</plugin>
		<plugin>
			<groupId>org.apache.maven.plugins</groupId>
			<artifactId>maven-failsafe-plugin</artifactId>
			<configuration>
				<systemPropertyVariables>
					<test.server.port>${tomcat.http.port}</test.server.port>
				</systemPropertyVariables>
			</configuration>
		</plugin>
	</plugins>
</build>

现在,您可以在任何集成测试中检索 test.server.port 系统属性,以创建到服务器的正确 URL

自定义 JMX 端口

jmxPort 属性允许自定义插件用于与 Spring Boot 应用程序通信的端口。

此示例展示了如何在 9001 已被使用的情况下自定义端口:

<build>
	<plugins>
		<plugin>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-maven-plugin</artifactId>
			<configuration>
				<jmxPort>9009</jmxPort>
			</configuration>
			<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>
		</plugin>
	</plugins>
</build>

提示:如果需要配置 JMX 端口,请确保在全局配置中进行,如上所示,以便两个目标共享。

跳过集成测试

skip 属性允许完全跳过 Spring Boot maven 插件的执行。

此示例展示了如何使用命令行属性跳过集成测试,并仍然确保 repackage 目标运行:

<project>
	<properties>
		<skip.it>false</skip.it>
	</properties>
	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
				<executions>
					<execution>
						<id>pre-integration-test</id>
						<goals>
							<goal>start</goal>
						</goals>
						<configuration>
							<skip>${skip.it}</skip>
						</configuration>
					</execution>
					<execution>
						<id>post-integration-test</id>
						<goals>
							<goal>stop</goal>
						</goals>
						<configuration>
							<skip>${skip.it}</skip>
						</configuration>
					</execution>
				</executions>
			</plugin>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-failsafe-plugin</artifactId>
				<configuration>
					<skip>${skip.it}</skip>
				</configuration>
			</plugin>
		</plugins>
	</build>
</project>

默认情况下,集成测试将运行,但此设置允许您在命令行上轻松禁用它们,如下所示:

$ mvn verify -Dskip.it=true
