我正在尝试使用PAX考试设置测试,如下所示:

@ExamReactorStrategy(PerMethod.class)
public class AbstractTest {

    @Configuration
    public Option[] config() {
        return options(
                junitBundles(),

                /* PAX Logging */
                mavenBundle("org.ops4j.pax.logging", "pax-logging-api", "1.7.2"),
                mavenBundle("org.ops4j.pax.logging", "pax-logging-service", "1.7.2"),

                /* Apache Felix Config Admin */
                mavenBundle("org.apache.felix", "org.apache.felix.configadmin", "1.8.0"),

                /* Eclipse Gemini dependencies */
                mavenBundle().groupId("org.aopalliance").artifactId("com.springsource.org.aopalliance").versionAsInProject(),
                mavenBundle().groupId("org.springframework").artifactId("org.springframework.aop").versionAsInProject(),
                mavenBundle().groupId("org.springframework").artifactId("org.springframework.beans").versionAsInProject(),
                mavenBundle().groupId("org.springframework").artifactId("org.springframework.context").versionAsInProject(),
                mavenBundle().groupId("org.springframework").artifactId("org.springframework.core").versionAsInProject(),

                /* Eclipse Gemini */
                mavenBundle("org.eclipse.gemini.blueprint", "gemini-blueprint-core", GEMINI_VERSION),
                mavenBundle("org.eclipse.gemini.blueprint", "gemini-blueprint-extender", GEMINI_VERSION),
                mavenBundle("org.eclipse.gemini.blueprint", "gemini-blueprint-io", GEMINI_VERSION),

                /* Other bundles */;
    }

    @Before
    public void setUp() throws Exception {
        ....
    }

}


@RunWith(PaxExam.class)
public class MyTest extends AbstractTest {

    @Inject
    private MyObject myObject;

    @Test
    public void testOne() {
        ...
    }

}

出于某种原因,未调用使用@Before注释的方法。

谢谢,Mickael

我已经设置了一个测试项目并且工作正常。

我终于找到了造成这个问题的原因。似乎在配置期间停止了测试的执行。

我使用Eclipse Gemini 2.0.M02并在我的应用程序上下文中使用占位符。例如,我需要将数据源URL设置为property。我想使用@Before方法使用Configuration Admin服务为PID设置配置。

由于在配置期间加载了应用程序上下文,并且此时未配置PID(因为尚未调用@Before方法),我从Spring收到错误导致PAX EXAM中止执行目前的测试。

因此,在我的情况下,我无法使用@Before方法中的配置管理服务。

解决方案是使用 pax-exam-cm 模块,该模块允许在配置方法中与Configuration Admin Service进行交互,如下所示:

@Configuration
public static Option[] config() {
    return options(
            junitBundles(),

            /* PAX Logging */
            mavenBundle("org.ops4j.pax.logging", "pax-logging-api", "1.7.2"),
            mavenBundle("org.ops4j.pax.logging", "pax-logging-service", "1.7.2"),

            /* Apache Felix Config Admin */
            mavenBundle("org.apache.felix", "org.apache.felix.configadmin", "1.8.0"),

            ConfigurationAdminOptions.newConfiguration("my.pid")
                .put("prop1", "value1")
                .put("prop2", "value2")
                .asOption(),

            /* Eclipse Gemini + dependencies */
            mavenBundle().groupId("org.aopalliance").artifactId("com.springsource.org.aopalliance").versionAsInProject(),
            mavenBundle().groupId("org.springframework").artifactId("org.springframework.aop").versionAsInProject(),
            mavenBundle().groupId("org.springframework").artifactId("org.springframework.beans").versionAsInProject(),
            mavenBundle().groupId("org.springframework").artifactId("org.springframework.context").versionAsInProject(),
            mavenBundle().groupId("org.springframework").artifactId("org.springframework.core").versionAsInProject(),
            mavenBundle("org.eclipse.gemini.blueprint", "gemini-blueprint-core", GEMINI_VERSION),
            mavenBundle("org.eclipse.gemini.blueprint", "gemini-blueprint-extender", GEMINI_VERSION),
            mavenBundle("org.eclipse.gemini.blueprint", "gemini-blueprint-io", GEMINI_VERSION),

            /* Other bundles */
            );
}

您还需要将 pax-exam-cm 依赖关系添加到您的POM(如果您使用Maven):

<dependency>
    <groupId>org.ops4j.pax.exam</groupId>
    <artifactId>pax-exam-cm</artifactId>
    <version>3.4.0</version>
    <scope>test</scope>
</dependency>
