Question

我使用java.util.logging来记录我的程序，问题是我需要为每个类测试用例的实例创建单独的日志文件。例如，我有三个测试用例对象，最后我得到三个日志文件，但是：

测试用例＃3包含测试用例＃3的日志，测试用例＃2包含测试用例2和3的日志，测试用例＃1包含所有测试用例的日志。

这是我的代码：

public class TestCase {
    TestCase(String tcName){
        this.tcName = tcName;
    }

    Logger log = Logger.getLogger("com.sigmaukraine.trn.autotest.testcase");
    String tcName;
    String scenarioReportDir;
    List<Keyword> kwList = new ArrayList<Keyword>();

public void executeTestCase(){
            //saving log for current test case
            try {
                FileHandler fh;
                String fileName = new StringBuilder(tcName).append(".log").toString();
                // This block configure the logger with handler and formatter
                fh = new FileHandler(scenarioReportDir + fileName);
                log.addHandler(fh);
                SimpleFormatter formatter = new SimpleFormatter();
                fh.setFormatter(formatter);
                log.info("Executing test case: " + tcName);

            } catch (SecurityException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
            for(Keyword k : kwList){
                k.executeKeyword();
            }


        }

Answer 1

问题在

log.addHandler(fh);

继续添加处理程序。所以行为就像你所看到的那样。你应该使用

fh.close();
log.removeHandler(fh);

执行测试用例后。
