LoadFocus.com: 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.

Steps:
1. Takes screenshots of your webpages (URLs)
2. Run a comparison task across them
3. Output a diff PNG file comparing the two images with the number of pixels that have changed.
4. If any screenshot’s diff is above the threshold you specified, the test Passes.
5. The failed screenshot will also be highlighted in the list.

 

LoadFocus.com: 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).

Filed under Page Load Time, Website Speed Testing.

Website 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

Load 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 LoadFocus.com, an online cloud testing platform, that runs from your browser. No coding or configuration needed.

Do you have an idea how does your website behave when you send a 10k emails campaign. Is it going to be UP, DOWN, how is the overall user experience going to be?

LoadFocus runs in the browser, so no need to install anything. You can run tests from multiple locations around the world for a better and more realistic results.
You can configure your load tests by duration to identify application behaviour when x clients connect on the app in parallel over a period of time, or by number of repeats to inspect application behaviour when x clients connect for x times on your application.

Live load test results help you understand the behaviour of your application in real-time, and hints on current results are displayed in order to understand how to continue with the next load test.
For every load test you can inspect Response Time, Latency, Hits/second, Throughput/second, Standard Deviation, Percentiles 50th, 90th, 99th, which represent the most useful load testing and performance testing metrics.

For errors and response codes, charts are displayed with useful information to understand when these errors occurred, and have a better perception on how should you tweak your load tests in order to discover the exact scenarios that are breaking your application.
