DropwizardAppRule和maven-failsafe-plugin

Question

這是我DropwizardAppRule在MyAppIT.java類：

@ClassRule
public static final DropwizardAppRule<MyConfiguration> RULE =
        new DropwizardAppRule<>(MyApplication.class, YAML_PATH);

這將返回我的本地Dropwizard應用運行的LocalPort ：

RULE.getLocalPort()

在IntelliJ運行時，它返回9998並通過所有測試，但是當我從命令行執行mvn clean install或mvn verify ，它將引發NullPointerException並且我看到一堆Connection refused錯誤。

ERROR! javax.ws.rs.ProcessingException: java.net.ConnectException: Connection refused

這是我的maven-failsafe-plugin配置：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>2.18.1</version>
    <configuration>
        <includes>
            <include>MyAppIT.java</include>
        </includes>
        <systemProperties>
            <property>
                <name>test.environment</name>
                <value>${test.environment}</value>
            </property>
        </systemProperties>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>integration-test</goal>
                <goal>verify</goal>
            </goals>
        </execution>
    </executions>
</plugin>

似乎DropwizardAppRule甚至沒有啟動（因為端口為null）。 我想念什么？

Answer 1

我將MyAppIT.java包含到了maven-surefire-plugin surefire maven-surefire-plugin ，它的工作原理是：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.19.1</version>
    <configuration>
        <includes>
            <include>MyAppIT.java</include>
        </includes>
    </configuration>
</plugin>
