如何修复量角器，log4js配置错误？

Question

我在试着做量角器测试。但是面对log4js的问题。我做了npm安装log4js。启动前的配置看起来正确吗？对于当前版本的log4js，有什么需要更改的格式吗？

以下是错误：

Error: Problem with log4js configuration: ({
  appenders: {
    out: {
      type: 'log4js-protractor-appender',
      category: 'protractorLog4js'
    },
    app: {
      type: 'file',
      filename: './logs/ExecutionLog.log',
      category: 'protractorLog4js'
    }
  },
  categories: { default: { appenders: [ 'out', 'app' ], level: 'info' } }
}) - appender "out" is not valid (type "log4js-protractor-appender" could not be found)

    at Array.forEach (<anonymous>)
    at Object.configure (C:\Project\PrjectName\node_modules\log4js\lib\configuration.js:46:13)
npm ERR! Test failed.  See above for more details.

这是我在配置文件中的启动前配置。

beforeLaunch:function(){
          log4js.configure({
            appenders: {
              out:{ type: 'log4js-protractor-appender'},
              app:{ type: "file",
                    filename: './logs/ExecutionLog.log'}
              },
            categories: {
                    default: { appenders: [ 'out', 'app' ], level: 'info' }
            }
            });
        },

谢谢

log4js支持的追加程序类型为：

export type Appender = CategoryFilterAppender
    | ConsoleAppender
    | FileAppender
    | SyncfileAppender
    | DateFileAppender
  | LogLevelFilterAppender
  | NoLogFilterAppender
    | MultiFileAppender
    | MultiprocessAppender
    | RecordingAppender
    | StandardErrorAppender
    | StandardOutputAppender
    | CustomAppender;

如果从名称中删除"appender“，您将得到受支持的ex类型:控制台、文件、多文件.等

下面是一个简单的配置。

const log4js_config: Configuration = {
        appenders: {
            consoleErrors: {
                type: 'logLevelFilter',
                appender: 'console',
                level: 'error'
            },
            console: {
                type: 'console'
            },
        },
        categories: {
            default: { appenders: [ 'console', 'consoleErrors' ], level: 'debug' }
        }
    };

const Log4js = require('log4js');
log4js.configure(LOG4JS_CONFIGURATION);

就像这样，默认类别中有两种类型的追加器。

无论level.

• consoleErrors重写控制台的其他规则，
• 控制台附录程序都将记录控制台中的所有内容，并且只过滤控制台的错误级别消息或更高级别的消息。
