Writing a log file for Protractor/Jasmine tests without using command line

Question

I'm aware that if you were to do something like protractor config.js > file.log all the console output would be written to file.log.

Is there a way to do this/access that output from within the tests though so that I can use a dynamic path that's created with my reporting tool? And also in a way that I don't lose the console output.

Edits:

To elaborate a little further, I'm not only interested in console.log output. I'm interested in everything that comes from what seems to be protractors testLogger. For example, at the end of a suite's execution I am presented with: [13:19:37] I/launcher - 0 instance(s) of WebDriver still running [13:19:37] I/launcher - internet explorer #01-0 failed 4 test(s) [13:19:37] I/launcher - internet explorer #01-1 failed 1 test(s) [13:19:37] I/launcher - internet explorer #01-2 failed 1 test(s) [13:19:37] I/launcher - internet explorer #01-3 failed 1 test(s) [13:19:37] I/launcher - overall: 7 failed spec(s)

I would like that in addition to the other console output.

Answer 1

What I would suggest is instead of writing any required information to console and trying to make your reporter read it, I would suggest you to implement logging from your tests to get better control.

Instead of a console.log() - have something like logger().info("Testing Log4js") and then make your reporter operate on it.

If you are further interested there is js version of log4j called - log4js that I tried with Protractor and its works fine.

In case you are further interested here is the link to implementation examples

Complete code example for reference:

Steps to setup log4js for Protractor framework

Step 1: Install log4js npm module

Step 2: Create a helper js file – which will create the logger object which can be imported to tests

'use strict';
var log4js = require('log4js');
var log4jsGen = {
    getLogger: function getLogger() {
        log4js.loadAppender('file');
        log4js.addAppender(log4js.appenders.file('./logs/ExecutionLog.log'), 'logs');
        var logger = log4js.getLogger('logs');
        return logger;
    }
};

module.exports = log4jsGen;

Step 3: Import the helper file and call the getlogger() method to add logging statements to your tests

var log4jsGen = require("../Utilities/log4jsGen");
log4jsGen.getLogger().info("Testing Log4js");
