HLS testing using JMeter and Locust

HTTP Live Streaming (also known as HLS) is an HTTP-based adaptive bitrate streaming communications protocol implemented by Apple Inc. The conception of the protocol is based on the principle of splitting a single stream into small fragments sequentially downloaded via HTTP. At the beginning of the session, the playlist is downloaded in the M3U format, containing metadata about the existing nested streams. Based on standard HTTP transactions, HTTP Live Streaming can pass through any firewall or proxy server, passing standard HTTP traffic, unlike UDP-based protocols such as RTP. The standard also includes a standard encryption mechanism and secure-key distribution using HTTPS. Let’s look at how to test HLS using Apache JMeter and Locust.

Predicting product item category in 10 lines of code

Why on earth?

If you somehow deal with storing or processing any kinds of goods – than a problem of assigning a category set to your product items will arise sooner or later, and the problems may be the following:

  • You are running a web-store, and you want to facilitate a user to navigate your site and search items with help of categories.
  • You have a dataset with items that miss categories mapping, and you want to do some research on aggregated clusters of products.
  • You are going to introduce a recommendation system in your online-store, and you want it to take categories into account for more precise predictions.
  • All other cases when you need categories, but don’t have them.

Of course – the most straightforward solution is to develop your own categories classification and assign a category to each product item manually, but that’s not always the case – because you may not have a ready-to-use inventory of categories, and you need to do the following:

  • create a set of categories by yourself
  • assign a suitable category to each item, predicting it from its name.

Gonna do the stuff? Quite hard, isn’t it? But fortunately we have a plan:

How to teach Raspberry to detect movement

Introduction

Everyone has surely watched a movie about the future at least one time in their life. As for me, I have watched plenty of them and there are a lot of really good ones. But how good and funny it was to watch a movie about the adventures of Marty McFly and how disappointing it was when 21 October 2015 came true. We are the generation who have the opportunity to welcome the future that we saw in the childhood movies. Usually it’s not nearly as good as we imagined, but it’s only our fault. Today we have all the necessary tools to make those dreams real.

The tool we needed is called: Internet of Things (IoT). The main idea of this technology is to connect different devices together to allow them to communicate with each other and control or be controlled by other devices. Using this technology, we can start from some basic things and connect our home devices one by one into one ecosystem. And at the end we will have a system similar to the ones we saw in the movies, when we have an AI assistant who understands voice commands and can control home devices and functions. And since we still have some time before 2029, let’s start the Skynet implementation.

How to switch to ISS Art from another software development partner

Choosing the right provider to outsource a software development project may be a tricky task. When looking for a provider, a variety of factors should be taken into account. Based on our experience, the most important things to consider are:

  • The expertise of the team – whether they possess the knowledge and experience to handle your project;
  • The transparency of their processes – whether the team informs Customer about everything that happens in a timely manner, including issues that arise, and whether there is a way to solve them.

Having a reliable development partner to work with all the way, from the project idea discussion to the product launch and support is what customers typically seek for. Unfortunately, sometimes unexpected issues arise, and you might even have to go separate ways with your vendor.

Real life examples of how to use pairwise technique in test design

It’s clear that there’s a point where a comprehensive testing cannot be performed by creating a set of tests using a non-formal or even random approach. Experienced testers have to address different testing techniques to maintain acceptable level of coverage and high bug detection rate within a tight schedule. In this article we are going to look at and get familiar with one of the most effective yet easy-to-use testing techniques called pairwise testing.
