Page Load & Bandwidth & Latency Relation

(Picture from High-Performance Browser Networking)

Latency: The time from the source sending a packet to the destination receiving it.

Bandwidth: Maximum throughput of a logical or physical communication path.

What is BrowserMob Proxy?

BrowserMob Proxy is a free tool that supports monitoring and manipulating the network traffic from web applications. You can download it from https://github.com/lightbody/browsermob-proxy

On that page its definition is as follows: BrowserMob Proxy allows you to manipulate HTTP requests and responses, capture HTTP content, and export performance data as a HAR file . BMP works well as a standalone proxy server, but it is especially useful when embedded in Selenium tests.

Features of BrowserMob Proxy

The proxy is programmatically controlled via a REST interface or by being embedded directly inside Java-based programs and unit tests. It captures performance data in the HAR format. In addition, it can actually control HTTP traffic, such as:

Black-listing and white-listing certain URL patterns

Simulating various bandwidth and latency

Remapping DNS lookups

Flushing DNS caching

Automatic BASIC authorization

What is HAR?

The HAR format is based on JSON, as described in RFC 4627 . Har is an open format for exporting HTTP tracing information called HTTP Archive (HAR). The data is stored as a JSON document.

What kind of information we can get from har file:

DNS information load time

E ach object requested (load time)

Connection time to the server

From server to a browser (load time)

The object is blocked or not

Some of HAR object types are log, creator, browser, pages, page timings, etc.

We can check har file results using different tools:

softwareishard (online, installation here )

Monitoring service

Developer tools

HAR viewer is a free and open-source (PHP + JavaScript) application, which you can host yourself.

The gem will start a local server and automatically open a browser tab to view the HAR file.

If you go to harviewer website , copy and past your . har file inside & you will get an interactive timeline.

You can format the file using Notepad++ json viewer plugin, or JSON viewer website , you can get more information about har specification from here .

You can check the new browser mob proxy interface and its methods from this link 
Chrome Developer Tools
Copy All as HAR: Copies all resources to the system clipboard as HAR data. A HAR file contains a JSON data structure.
Save as HAR with Content: Saves all network data to a HAR file along with each page resource.
Chrome Developer Tools, go to the Network tab, and make sure you’ve selected the Preserve log checkbox, otherwise, the log is reset when you change the page.
Unfortunately with the latest selenium versions create problems. I tried all options to fix the problem but I could not. If you find a solution to run BrowserMobProxy with Selenium’s latest versions, please write a comment about that solution or you can create PR in github repo.

					I am using browser-mob with Nightwatch js, Is there any way by which I can start my server directly from my tests?
Reply				
					You may use below options:

– https://toolbox.googleapps.com/apps/har_analyzer/

– http://www.softwareishard.com/blog/har-viewer/
You can try to use these libraries in Java to read HAR file:

					I got the har file from browsermob  but unable to convert that har file to JMX.

Can you please provide me solution for the same.

					When I tried convert Har to Jmx through blazemeter then it’s showing me “Fatal error during conversion:

					It is better to ask Blazemeter support. :( This part has a problem. It can not find json schema.

Reply				
					Nani, I really would like to help but nowadays I am super busy. If I will have time, I will help. But I will also search this on the internet. But when I read your request, I think it is better to do this with Rest-Assured. As I understand, you are trying to compare an API result and that result format is JSON. With rest-assured you can do this much easier. Please check here: http://www.swtestacademy.com/api-testing-with-rest-assured/
