使用量角器记录控制台错误 [英] Log console errors using protractor

问题描述

我正在尝试像这样在量角器中记录控制台错误

I am trying to log console errors in protractor like this

日志输出采用格式

{
  level: {
    value: 900,
    name: 'WARNING'
  },
  message: 'message',
  timestamp: 1442090739962,
  type: ''
}, {
  level: {
    value: 800,
    name: 'INFO'
  },
  message: 'message',
  timestamp: 1442090740723,
  type: ''
}, {
  level: {
    value: 1000,
    name: 'ERROR'
  },
  message: 'error message',
  timestamp: 1442090740723,
  type: ''
},

我只想捕获错误，所以我已经编写了这样的测试

I want to catch only errors so i have written test like this

it('it should be detect console errors', function() {
  browser.manage().logs().get('browser').then(function(browserLogs) {
    // browserLogs is an array of objects with level and message fields
    browserLogs.forEach(function(log) {
      if (log.level.value > 900) { // it's an error log
        console.log('Browser console error!');
        console.log(log.message);
      }
    });
  });
});

问题是它有时会捕获错误，有时不会.

Problem is it's catching errors sometimes and sometimes not.

当我输入错误的websocket路径时，如果出现错误，则将其记录下来.但是，当我给出错误的 ng-include 路径，并且如果控制台中出现 404错误时，它就不会记录日志.

when i give wrong path to websocket and if there is an error then it is logging it. But When I give wrong path to ng-include and if there is a 404 error in console then it's not logging.

我正在使用firefox进行测试.这个控制台插件浏览器是依赖的​​还是什么?为什么控制台错误显示不同的行为?

I am using firefox for testing. Is this console plugin browser dependent or what? Why it is showing different behaviour for console errors?

推荐答案

有类似的问题，所以我写了包装功能

injectConsoleTracing = function () {
    browser.executeScript('window.errs=typeof(errs)=="undefined" ? [] : window.errs; window.console.error = function(msg){window.errs.push(msg); }; ');
    browser.executeScript('window.logs=typeof(logs)=="undefined" ? [] : window.logs; window.console.log = function(msg){window.logs.push(msg); }; ');
};

expectNoConsoleErrors = function () {
    browser.executeScript('return window.errs;').then(function (v) {
        expect(v).toEqual([]);
    });
    browser.executeScript('return window.logs;').then(function (v) {
        expect(v).toEqual([]);
    });
};
