如何在独立的JUnit测试用例之间实现公共数据共享

public class SharedData {
    public static final String COMMON_DATA = "shared data";
}

public class TestClassA {
    @Test
    public void testMethodA() {
        assertEquals(SharedData.COMMON_DATA, "shared data");
    }
}

public class TestClassB {
    @Test
    public void testMethodB() {
        assertEquals(SharedData.COMMON_DATA, "shared data");
    }
}

common.data=shared data

public class SharedDataUtil {
    private static Properties properties = new Properties();

    static {
        try (InputStream input = SharedDataUtil.class.getClassLoader().getResourceAsStream("data.properties")) {
            properties.load(input);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static String getCommonData() {
        return properties.getProperty("common.data");
    }
}

public class TestClassA {
    @Test
    public void testMethodA() {
        assertEquals(SharedDataUtil.getCommonData(), "shared data");
    }
}

public class TestClassB {
    @Test
    public void testMethodB() {
        assertEquals(SharedDataUtil.getCommonData(), "shared data");
    }
}
