In a recently posted article on DZone, “Microservices: Good for Developers’ Mental Health,” Sauce Labs engineer, Simone Pezzano, addresses the link between developer confidence and mental health in today’s new workplace. Pezzano tells the story of his team’s bumpy start on their journey from monolith to microservices. Initially, Pezzano viewed microservices as a scary concept with rapid release cycles and shorter testing times.

During the holiday break, our family had to get tested for COVID. We got at-home tests, as they were available, and it was easier than having to wait in line at a testing center. This got me thinking of a recent article in the New York Times, which raises the notion that experts are questioning the importance/value of measuring COVID caseloads with the rise in the use of at home tests.

Pearson, founded in the 19th century, is one of the world leaders in providing education services all around the globe. Francisco Muniz is the Performance Architect for Pearson, responsible for Performance Alignment across Pearson’s Virtual Learning. This position entails working with many different parts of the organization, such as Architecture, Development, and QA. As such, Francisco was leading and overseeing the important Octoperf and Loadrunner software switching project.

Unit testing ensures that every feature or component of a program functions as intended. Unit testing is carried out by developers during the development sprint stages. This assists them in identifying and correcting tiny faults that might lead to larger issues in later stages. Previously, conducting unit tests on a built module was a time-consuming and laborious effort since developers had to manually test code for each component. As a result, final release dates were pushed back.

A defect, in simple language, is a flaw in a system i.e., a system is not working as it should. Defects are also called bugs or faults. In case of software, when the software code has been built, it is executed and then any defects may cause the system to fail to do what it should do (or do something it shouldn't), causing a failure. However, not all defects result in failures.

Today, software applications need to deliver a consistent and reliable experience across multiple browsers, operating systems, and devices. To accomplish this, companies are spending valuable resources and time manually deploying dedicated test infrastructures. This translates into a limited availability of test scenarios and prevents companies from generating enough test coverage to ensure the best user experience across the most commonly used platforms.

In this article, you will learn how to test database performance in Rails and solve some of the most common database performance issues. When you develop a Rails application, ActiveRecord is the default tool that manages your database. ActiveRecord provides an easy and fast interface to query and insert data using commands like.where, .save, .create, and.update. Rails does the work of converting these commands to SQL queries, which is a good thing, but sometimes can cause performance issues.

A lot of things got easier in 2021 as technology advanced tremendously to continue making the digital world more accessible and integrated into our everyday lives. But luckily there was something that got harder in 2021: being irresponsible with data. You see, with great power comes great responsibility, and as people’s data gets poured online, more and more restrictions appear to ensure that data is always safe, without exceptions.

Kubernetes is hard. Last year, we started the developer experience product at American Airlines. As we transitioned into the later half of 2020 and into 2021, we wanted to tackle Kubernetes app deployments. We aimed to make it easy for the users to do the right things, no matter how difficult those tasks were. Through our Kubernetes journey, we created reproducible patterns for application teams to use to make things even easier.
