We’ve introduced an easy way to find which technologies are used by the website under test, in case you have ever wondered on how to find what technology is behind the particular website.

In order to find out what technology is used by a website, just scroll on the results page to check the Built With Technology section. It detects CMS, CRM, , E-Commerce platforms, web frameworks, server software, analytics tools and others. All you have to do is to put website name and then it shows all the information related to website.

Here is an example of a test, and now it’s also part of our Free Website Speed Test.

This will help you better understand by your website loads slower than expected, and find out what other website are using in terms of the scripts and technologies behind that website, and find out more information about competitors.

Visual Regression Testing tool from LoadFocus allows to compare two version of your website in just seconds. Let’s say that you have two environments for your website, Staging and Production, and you want to make sure that any visual change you made on the Staging version is expected and now other changes/bugs are going to be introduced.

With Visual Regression Testing tool you can create a test where you define the two versions of your website, with every webpage that you want to run the screenshot comparison test.

Screenshot Testing Test Automation UI Testing

1 minute Screenshot Comparison tool is visual regression testing of your responsive web UI by comparing DOM screenshots
screenshot test application for responsive websites and web-applications.

The Screenshot Comparison tool uses a headless browser to create screenshots of webpages on different environments and then creates a diff of the two images with the affected areas are highlighted in red.

1. Takes screenshots of your webpages (URLs) Free Screenshot Comparison tool is useful to test responsive layouts since it’s very hard and time consuming to test all of a project’s screen elements at every breakpoint.

Visual regression allows you to make comparisons based on (pixel differences) between the baseline versions of the site and the version in development (comparing staging vs. production environments).

Page Load Time Website Speed Testing

1 minute readWebsite speed testing metrics are useful when you understand what do they mean and which are the most important metrics that you need to consider. Below is a list of metrics used in website speed testing that you may find useful, here are the metrics and their definitions:

First byte – Delay between the first HTTP request from the web browser and the reception of the first byte of the web page by the browser
It’s recommended a time less than 200 ms

DOM Ready – Delay between the first request from the web browser and the first display on the user’s screen
It’s recommended that the visible part of your web page appears in less than 1 second

Load time – The web page is fully loaded, all the resources are fetched, parsed and executed
Page must be loaded within 4 seconds

Page size – The total size of assets loaded: CSS, JS, HTML + other

Page score – The score calculated based on a number of factors: compression of the resources, enable/disable caching, CSS/HTML/JS minifying etc

Run a website speed test now to check how fast is your website and find potential improvements.

Load Testing Performance Testing Stress Testing

1 minute readLoad testing should be an easy, on going task that your team should focus in terms of constantly improving the quality of your application.

LoadFocus is an easy to use, in browser, cloud load testing application which allows to simulate load tests from the browser to your application with up to 600k connections per test. This should give you an overall idea of how your application behaves in terms of high load.

Make your you start your load test with a lower number of clients and check the live results, in order to find potential bottlenecks of the website, API or any web service you are trying to debug.

Increase the load gradually, to understand where the errors start to appear, and the time metrics increase more than expected.

At the beginning of your test, you should understand which is the current load on your website and run load test much above your current average, just to be able to handle unexpected load on your application.

Load tests are easy to run using, an online cloud testing platform, that runs from your browser. No coding or configuration needed.
