1.13. 测试原生可执行文件

流程

1. 打开 pom.xml 文件，并验证 build 部分是否具有以下元素：

   <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-failsafe-plugin</artifactId>
       <version>${surefire-plugin.version}</version>
       <executions>
           <execution>
               <goals>
                   <goal>integration-test</goal>
                   <goal>verify</goal>
               </goals>
               <configuration>
                   <systemPropertyVariables>
                       <native.image.path>${project.build.directory}/${project.build.finalName}-runner</native.image.path>
                       <java.util.logging.manager>org.jboss.logmanager.LogManager</java.util.logging.manager>
                       <maven.home>${maven.home}</maven.home>
                   </systemPropertyVariables>
               </configuration>
           </execution>
       </executions>
   </plugin>

   • Maven Failsafe 插件(maven-failsafe-plugin)运行集成测试，并指示生成的原生可执行文件的位置。

2. 打开 src/test/java/org/acme/GreetingResourceIT.java 文件，并验证该文件是否包含以下内容：

   package org.acme;
   
   import io.quarkus.test.junit.QuarkusIntegrationTest;
   
   @QuarkusIntegrationTest 1
   public class GreetingResourceIT extends GreetingResourceTest { 2
   
       // Execute the same tests but in native mode.
   }

   1

   在测试之前，使用另一个测试运行程序从原生文件启动应用。可执行文件通过使用 Maven Failsafe 插件中配置的 native.image.path 系统属性来检索。

   2

   本例扩展了 GreetingResourceTest，但您也可以创建新的测试。

3. 运行测试：

   ./mvnw verify -Dnative

   以下示例显示了这个命令的输出：

   ./mvnw verify -Dnative

   注意

   Quarkus 在自动失败原生测试前等待 60 秒启动原生镜像。您可以通过配置 quarkus.test.wait-time 系统属性来更改此持续时间。

   您可以使用以下命令扩展等待时间，其中 < duration> 是等待时间（以秒为单位）：

   ./mvnw verify -Dnative -Dquarkus.test.wait-time=<duration>

   注意
   • 默认情况下，使用 prod 配置集运行原生测试，除非在 quarkus.test.native-image-profile 属性中进行了修改。
