我需要为一个设计很差的旧应用程序编写JUnit测试,并将大量错误消息写入标准输出.当getResponse(String request)方法行为正确时,它返回XML响应:

@BeforeClass
public static void setUpClass() throws Exception {
    Properties queries = loadPropertiesFile("requests.properties");
    Properties responses = loadPropertiesFile("responses.properties");
    instance = new ResponseGenerator(queries, responses);
}

@Test
public void testGetResponse() {
    String request = "<some>request</some>";
    String expResult = "<some>response</some>";
    String result = instance.getResponse(request);
    assertEquals(expResult, result);
}

但是当它得到格式错误的XML或者不理解它返回的请求并将null一些东西写入标准输出时.

有没有办法在JUnit中断言控制台输出？要抓住像这样的案例:

System.out.println("match found: " + strExpr);
System.out.println("xml not well formed: " + e.getMessage());
