java如何在两个测试类之间共享外部资源?
我正在努力理解使用ExternalResource
的好处。documentation和其他帖子(How Junit @Rule works?)都暗示了能够在类内的测试之间共享代码和/或在测试类之间共享代码
我试图在功能/集成测试中使用ExternalResource
作为DB连接,但我不知道如何在类之间共享该连接。事实上,在这种情况下,我并不认为@Before/@After
有什么好处。我是不是用错了,还是我遗漏了什么
public class some_IntegrationTest {
private static String id;
Connection connection = null;
//...
@Rule
public ExternalResource DBConnectionResource = new ExternalResource() {
@Override
protected void before() throws SQLException {
connection = DbUtil.openConnection();
}
@Override
protected void after() {
DbUtil.closeConnection(connection);
}
};
@BeforeClass
public static void setUpClass() throws SQLException {
System.out.println("@BeforeClass setUpClass");
cleanup(id);
}
//I want to do something like this
@Test
public void test01() {
cleanupData(connection, id);
// do stuff...
}
@Test
public void test02() {
cleanupTnxLog(connection, id);
// do stuff...
}
//...
private static void cleanup(String id) throws SQLException {
LOGGER.info("Cleaning up records");
Connection connection = null;
try {
connection = DbUtil.openConnection();
cleanupData(connection, id);
cleanupTnxLog(connection, id);
} finally {
DbUtil.closeConnection(connection);
}
}
private static void cleanupData(Connection connection, String id)
throws SQLException {
dao1.delete(connection, id);
}
private static void cleanupTnxLog(Connection connection, String id)
throws SQLException {
dao2.delete(connection, id);
}
}

我会这样做:
然后在测试中使用它,如下所示:
