如何在JUnit测试中管理JNDI上下文？

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>javax.naming</groupId>
    <artifactId>jndi-api</artifactId>
    <version>1.2.1</version>
    <scope>test</scope>
</dependency>

@BeforeClass
public static void setUp() throws Exception {
    // 使用SimpleNamingContextBuilder初始化JNDI上下文
    SimpleNamingContextBuilder builder = new SimpleNamingContextBuilder();
    builder.bind("java:comp/env/myDataSource", new MyDataSource());
    builder.activate();
}

@Test
public void testJndiContext() {
    // 获取JNDI上下文中的数据源
    DataSource dataSource = (DataSource) new InitialContext().lookup("java:comp/env/myDataSource");
    // 执行测试逻辑
    // ...
}
