What Is Observability? Everything a Beginner Needs to Know
Observability originated in the field of engineering and has recently gained popularity in the world of software development. Put simply, observability refers to the ability to understand the internal state of a system based on its external outputs. In the context of software development, observability refers to the ability to understand the behavior and performance of an application based on the data it generates. This data can include logs, metrics, traces, and other telemetry data. By analyzing this data, developers can gain insight into how an application is functioning and identify areas where they can make improvements.

A Guide to OpenTelemetry for .NET Engineers
OpenTelemetry is an open-source observability framework for cloud-native software that provides a way to collect, analyze, and visualize traces and metrics from your applications. It’s a project under the Cloud Native Computing Foundation (CNCF) and is quickly becoming the standard for telemetry data collection. Check out this guide from Juan Reyes on Stackify’s blog where you can explore the world of OpenTelemetry, focusing on how it can benefit your .NET applications.
SLO vs SLA vs SLI: A Complete Guide for DevOps Professionals
In today’s fast-paced world of software development, DevOps professionals strive to provide high-quality and dependable services for their users. An essential aspect of achieving this objective is understanding and effectively managing service level indicators (SLIs), service level objectives (SLOs) and service level agreements (SLAs). These metrics help guarantee that a service meets its performance and reliability targets. Metrics also help align the goals of different teams within an organization. This post from Keshav Malik on Stackify’s blog dives deep into the world of SLOs, SLAs and SLIs, shedding light on their importance for DevOps professionals.
How to Use Page Object Model in Selenium, With Examples
Selenium is one of the most popular tools when it comes to testing automation, and you can use it in a variety of ways, some of which don’t result in clean, concise code. Fortunately, there are design patterns you can leverage to make your Selenium tests look more organized and structured. This post covers one of them: the Page Object Model pattern, or simply POM. Learn more from Carlos Schults on Testim’s blog and by the end, you’ll understand what POM is, why you should care about it, and how to use it.
React Native run-android: How to Test Various Device Types
React Native is a popular framework for building mobile apps. It allows developers to create apps for both iOS and Android platforms using a single codebase. One of the key benefits of React Native is its ability to test apps on various device types, including emulators, simulators, and physical devices. In this tutorial from Keshav Malik on Testim’s blog, you’ll learn how to use the command-line tool react-native run-android to test apps on different Android devices.
An Introduction to Selendroid For End-to-End Testing
Selendroid, in short, is Selenium, but for Android. It’s a test automation framework powered by the Selenium client API that can drive the UI for native and hybrid Android applications. You can also use Selendroid to perform end-to-end tests on mobile web apps. You can use Selendroid to test applications without altering the source code of the application under test, which many developers consider a key feature. Hence, you can test just about any application as long as you have the Android package kit (APK). Find out more in this post from Pius Aboyi on Testim’s blog.
Easy Automated Unit Testing in Python: A Tutorial
Unit testing is writing automated tests that exercise small portions of the codebase—the so-called units—to verify whether they work as intended. Unit testing is one of the most important forms of automated software testing. That’s true for any programming language: Java, JavaScript, you name it. Python is no exception, and today we’re bringing you a unit-testing Python tutorial. Find out more in this post from Carlos Schults on Testim’s blog.
Why and How to Perform Manual Functional Testing
Functional tests are certainly worthy of being part of your testing suite and can be done either manually or in an automated way. This post, as its title suggests, is about the former variety. We’ll cover manual functional testing. We’ll open the post with some definitions explaining what manual functional testing means. Then, we’ll explain why you want to do it, even when automated functional testing is an alternative. Finally, we’ll get to the how of manual functional testing, giving instructions and covering best practices so you can start immediately. Get all of the details about manual functional testing in this post from Carlos Schults on Testim’s blog.
Non-Functional Testing Types: 7 Tests to Add to Your Test Suite
Non-functional testing is the type of software testing that test the non-functional parameters of the software. This includes usability, readability, scalability, and performance. While these are not critical to the software’s functionality, they contribute to the end-user experience. Find out more about non-functional testing from Ifeanyi Benedict Iheagwara on Testim’s blog.
