Introduction to Automation Testing Strategies for Microservices

Aggregated on: Wed Mar 08 2023 15:14:53 GMT+0000 (Coordinated Universal Time)

Microservices are distributed applications deployed in different environments and could be developed in different programming languages having different databases with too many internal and external communications. Therefore, a microservices architecture is dependent on multiple interdependent applications for its end-to-end functionalities. This complex microservices architecture requires a systematic testing strategy to ensure end-to-end (E2E) testing for any given use case. In this blog, we will discuss some of the most adopted automation testing strategies for microservices, and to do that, we will use the testing triangle approach. Testing Triangle It's a modern way of testing microservices with a bottom-up approach, which is also part of the "Shift-left" testing methodology (The "shift-left" testing method pushes testing towards the early stages of software development. By testing early and often, you can reduce the number of bugs and increase the code quality.). The goal of having multiple stacked layers of the following test pyramid for microservices is to identify different types of issues at the beginning of testing levels. So, in the end, you will have very few production issues. Each type of testing focuses on a different layer of the overall software system and verifies expected results. For a distributed microservices app, the tests can be organized into the following layers using a bottom-up approach:

Maven Troubleshooting, Unstable Builds, and Open-Source Infrastructure

Aggregated on: Tue Mar 07 2023 23:44:52 GMT+0000 (Coordinated Universal Time)

Donald Knuth famously wrote that Premature Optimization is the root of all evil. I, for one, believe that all evil comes from spuriously failing builds. Nothing steals my confidence in a project as quickly as unstable builds alternating between green and red for no reason. This is a story about unstable builds and troubleshooting. More importantly, this story is written to thank all contributors to basic software infrastructure — the infrastructure we all use and take for granted. Surprise in Logs Upon logging into Azure Pipelines to review the logs of multiple failed builds, I mentally braced myself for a potentially arduous troubleshooting session. I suspected that a race condition was the culprit that caused non-deterministic outcomes. Therefore, I was surprised to discover the actual reasons for the recent build failures. They were all similar to this:

GraphQL Frameworks

Aggregated on: Tue Mar 07 2023 22:14:52 GMT+0000 (Coordinated Universal Time)

GraphQL is a popular query language that allows developers to efficiently query data by specifying the data they need and how it should be structured. The language is independent of any specific database or storage mechanism and can be used with a variety of frameworks to create robust, scalable APIs. Unlike REST APIs, GraphQL provides a single endpoint for all requests, making it easier to develop and maintain APIs. There are several frameworks available to implement GraphQL, each with its own pros and cons.

Dependency Injection and Ways to Inject It Using .NET Core API

Aggregated on: Tue Mar 07 2023 21:14:52 GMT+0000 (Coordinated Universal Time)

In this article, we are going to discuss dependency injection and its usage and benefits. We will also discuss different ways to implement dependency injection. Prerequisites Basic understanding of the C# programming language. Understanding of Object-Oriented programming. Basic understanding of .NET Core. Purpose of the Dependency Injection Design Pattern In simple words, dependency means the object depends on another object to do some work. Using dependency injection, we can write loosely coupled classes and, because of that, our current functionality of one class does not directly depend on another class because we can easily maintain, change, and unit test code properly. It also takes care of the open-closed principle. Using abstraction and interface, we can make some future changes easily without modifying existing functionality.

Open Source Maintenance Is Community Organizing

Aggregated on: Tue Mar 07 2023 20:14:52 GMT+0000 (Coordinated Universal Time)

About six months ago, I wrote a piece about the state of open-source commercialization that garnered some notice. Almost immediately after that, Hacker News featured a problematic piece of prose on the front page. The title is “Fix it, Fork it, F*ck off” (censorship is mine). I think this is a great sample of where OSS is failing commercially and as a movement. A lot of the attention in OSS goes into the code of conduct policies (which are important), but not enough goes into what it takes to build a successful open-source project. It isn’t just the coding. I’d argue that coding is often less important than this. The Clash of Entitlement I understand where the author is coming from. He’s writing from frustration. We put a lot of work into our OSS project, and an entitled end user can be difficult. I agree some people go over the line, but in my experience, this is less than 0.1% of complaints. It’s rare to have a truly toxic user.

Direct socket connections can benefit all real-time applications since data can be sent or received anytime.

OWASP Kubernetes Top 10

Aggregated on: Tue Mar 07 2023 19:14:52 GMT+0000 (Coordinated Universal Time)

One of the biggest concerns when using Kubernetes is whether we are complying with the security posture and taking into account all possible threats. For this reason, OWASP has created the OWASP Kubernetes Top 10, which helps identify the most likely risks. OWASP's Top 10 projects are useful awareness and guidance resources for security practitioners and engineers. They can also map to other security frameworks that help incident response engineers understand Kubernetes threats. For example, MITRE ATT&CK techniques are also commonly used to register the attacker's techniques and help blue teams to understand the best ways to protect an environment. In addition, we can check the Kubernetes threat model to understand all the attack surfaces and main attack vectors.

It enables teams to quickly pinpoint the root cause of issues, fix them and optimize the application performance, giving them the confidence to deliver code faster.

How To Automate an API Gateway Migration

Aggregated on: Tue Mar 07 2023 18:29:52 GMT+0000 (Coordinated Universal Time)

Application Programming Interfaces (APIs) and API management are critical business assets. Today’s businesses are scaling APIs to meet different business needs with varying types of APIs, specifications, and functions across enterprise environments and complex architectures. Smart developers understand the business value of APIs and the need to have an API strategy independent of API gateways and host locations. Any workable API strategy must include gateway-agnostic APIs so they can run on-premises, in the cloud, or in a hybrid environment. APIs also must be easy to port to any new gateway provider. Whether the organization uses APIs custom-built by the DevOps team or purchased as Software-as-a-Service (SaaS), using APIs to connect applications throughout the organization requires effective API management. As the speed of business accelerates, APIs need to move faster as well, which means APIs need to be unified and self-service to be more agile and more portable.

The Three Daily Scrum Questions Won’t Die

The Daily Scrum serves a single purpose: inspecting the progress toward the Sprint Goal by reflecting on yesterday’s learning. Then, if the need should arise, the Developers adapt their plan to accomplish the Sprint Goal. While the theory may be generally accepted, applying the idea to the practice is more challenging. One of the recurring issues is the continued popularity of the “three Daily Scrum questions” from the Scrum Guide 2017. Let’s reflect on why answering these obsolete Daily Scrum questions negatively influences the Scrum team.

Managing Multiple APIs Using an Adapter Pattern

Aggregated on: Tue Mar 07 2023 18:29:52 GMT+0000 (Coordinated Universal Time)

Let's imagine the problem: Your company creates a B2B product that provides a service for some other companies. This service helps client-company to resolve very specific problems of their customers. This customer can communicate with our company web app and do some operations. The results of these operations should be reported to the other company side. Times go on, and now you have a few more clients that work by the same scheme. At first, you connect small companies one by one, but when you get to much bigger client companies, you discover that they use third-party API service providers and delegate all the integration problems to them. These API service providers act as a proxy for this toil of service reverse integration, which unifies the logic of cross-company communication on both sides. Due to the structure of presented business relationships, our company almost inevitably start to use a set of similar actions to communicate with dozens of different APIs for hundreds of clients in the future.

Modern Web Applications Authentication Using Face Recognition

Aggregated on: Tue Mar 07 2023 17:59:52 GMT+0000 (Coordinated Universal Time)

With the development of digital technology, information systems are also constantly upgraded. In the past, we have developed many mature WEB application information systems. With the continuous improvement of security level, the traditional way of account login is getting worse and worse in the current user experience. For example, after you log in to the WEB application on one computer, when you change to another computer and enter the correct account and password to log in, the WEB application cannot determine whether it is you or someone else who logged in illegally because of the change of IP address and device. It will ask you to verify whether it is you again through email or mobile phone number. This security measure is reasonable, but it will make real users feel uncomfortable. If we add the facial authentication function in the user authentication module to confirm the current login user, this security measure can avoid a bad user experience. Facial authentication can be easily performed using FACEIO, and the amount of code added to WEB applications is very small. It provides online JavaScript libraries, which can be directly referenced in front-end web pages. Below the code

Apache Spark is a powerful open-source distributed computing framework that provides a variety of APIs to support big data processing. PySpark is the Python API for Apache Spark, which allows Python developers to write Spark applications using Python instead of Scala or Java. In addition, pySpark applications can be tuned to optimize performance and achieve better execution time, scalability, and resource utilization. In this article, we will discuss some tips and techniques for tuning PySpark applications. 1. Use Broadcast Variables Broadcast variables are read-only variables that can be shared across nodes in a Spark cluster. Broadcast variables can be used to efficiently distribute large read-only data structures, such as lookup tables, to worker nodes. This can significantly reduce network overhead and improve performance. In PySpark, you can use the broadcast function to create broadcast variables. For example, to broadcast a lookup table named lookup_table:

Secure APIs: Best Practices and Measures

Aggregated on: Tue Mar 07 2023 14:44:52 GMT+0000 (Coordinated Universal Time)

An API (Application Programming Interface) acts as an intermediary between two distinct software applications, enabling seamless communication and data exchange. By providing a standardized interface, APIs offer developers the ability to access specific functionalities or data from another software application or service without the need to understand or modify the underlying code. This results in more efficient development processes, improved interoperability between applications, and enhanced overall functionality. APIs represent a potent resource for developers as they offer a uniform approach to accessing data and functionality from various software applications and services, resulting in the creation of more efficient and effective software solutions. This not only streamlines the development process but also enhances the overall performance and scalability of the resulting applications. As the usage of APIs continues to rise, it is imperative that they are appropriately secured. Many industry-wide threats are the result of excessive or sensitive data being leaked through APIs. To mitigate this risk, it is essential to implement a shift left approach, which involves securing APIs from the development stage to maintenance. By integrating security measures at the earliest stage of the development process, developers can reduce the risk of potential vulnerabilities being introduced into the API. Additionally, regular maintenance and updates can ensure that any new vulnerabilities are identified and promptly addressed. Overall, implementing a shift left approach is critical to ensuring the security and protection of data being transmitted through APIs.

When applying hexagonal architecture (ports and adapters) with access to infrastructure elements like databases is done by the mean of adapters, which are just implementations of interfaces (ports) defined by the domain. In this article, we are going to provide two implementations of the same repository port, one in-memory and another based on JPA, focusing on how to test both implementations with the same set of tests. Context Many software solutions usually developed in the enterprise context have some state that needs to be persisted in a durable store for later access. Depending on the specific functional and non-functional requirements, selecting the correct persistence solution can be hard to make and most likely require an Architecture Decision Record (ADR) where the rationale of the selection, including alternatives and tradeoffs, is detailed. For persisting your application state, most likely, you will look at the CAP Theorem to make the most adequate decision.

Web development, like most technologies, moves in waves and cycles. Static websites were all we had in the beginning. But, pretty soon, developers were hacking together the first server-generated sites thanks to Perl and PHP. This was the advance that would eventually kickstart frameworks like Laravel, Django, or Rails. Mobile devices would come to change how people consume the web. So long server-generated websites, hello client-rendered applications. The next wave brought frameworks that could give users a more app-like experience—without reloads—like React or AngularJS.

Building Custom Solutions vs. Buy-and-Build Software

Aggregated on: Mon Mar 06 2023 23:14:52 GMT+0000 (Coordinated Universal Time)

The Challenges of Building a FIX Protocol The first day I was introduced to FIX was when I worked at an investment bank in London as a developer, I was told to write a feed handler to retrieve market data. Bear in mind that at this time, I knew nothing about FIX, apart from googling it for about 10 mins on the internet. With a touch of overconfidence and slight arrogance, I set to work coding a direct socket connection to the remote FIX endpoint, thinking, “How hard could it be?” So, What Is FIX? Financial Information eXchange (FIX) is both a market data format and a protocol: it is used by investment banks to place orders and receive market data and has become a global language in financial trading. The format of a FIX message controls how it is encoded. All FIX messages start with 8=FIX, which denotes the start of a FIX message. They then go on to list key and value pairs. The keys are represented as numbers (known as TagNumbers) followed by a = delimiter to delimit the values. Each key=value combination is then delimited by the \u0001 character, which is sometimes visually represented as either ^ or |. The value is often written in a semi-human-readable format. I say semi-human readable because most of the time it is human-readable, but all too often, FIX will use a single character to denote a state or type of message. These characters are not always that obvious. I agree that the character B for "Buy" and S for "Sell" makes sense, but other characters are used that make no sense. For example, D denotes a "New Order Single" message, which is a message that is often used when you wish to place an order with your counterparty.

20 Concepts You Should Know About Artificial Intelligence, Big Data, and Data Science

Aggregated on: Mon Mar 06 2023 18:29:52 GMT+0000 (Coordinated Universal Time)

Introduction Entrepreneurial ideas take advantage of the range of opportunities this field opens up, thanks to what is engineered by scientific profiles such as mathematicians or programmers. ALGORITHM. In Computer Science, an algorithm is a set of steps to perform a task. In other words, a logical sequence and instructions form a mathematical or statistical formula to perform data analysis. SENTIMENT ANALYSIS. Sentiment analysis refers to the different methods of computational linguistics that help to identify and extract subjective information from existing content in the digital world. Thanks to sentiment analysis, we can be able to extract a tangible and direct value, such as determining if a text extracted from the Internet contains positive or negative connotations. PREDICTIVE ANALYSIS. Predictive analysis belongs to the area of Business Analytics. It is about using data to determine what can happen in the future. The AP makes it possible to determine the probability associated with future events from the analysis of the available information (present and past). It also allows the discovery of relationships between the data that are normally not detected with less sophisticated analysis. Techniques such as data mining and predictive models are used. BUSINESS ANALYTICS. Business Analytics encompasses the methods and techniques used to collect, analyze, and investigate an organization's data set, generating insights that are transformed into business opportunities and improving business strategy. AE allows an improvement in decision-making since these are based on obtaining real data and real-time and allows business objectives to be achieved from the analysis of this data. BIG DATA. We are currently in an environment where trillions of bytes of information are generated every day. We call this enormous amount of data produced every day Big Data. The growth of data caused by the Internet and other areas (e.g., genomics) makes new techniques necessary to access and use this data. At the same time, these large volumes of data offer new knowledge possibilities and new business models. In particular, on the Internet, this growth begins with the multiplication in the number of websites, beginning search engines (e.g., Google) to find new ways to store and access these large volumes of data. This trend (blogs, social networks, IoT…) is causing the appearance of new Big Data tools and the generalization of their use. BUSINESS ANALYTICS (Business Analytics). Business Analytics or Business Analytics allows you to achieve business objectives based on data analysis. Basically, it allows us to detect trends and make forecasts from predictive models and use these models to optimize business processes. BUSINESS INTELLIGENCE Another concept related to EA is Business Intelligence (IE) focused on the use of a company's data to also facilitate decision-making and anticipate business actions. The difference with EA is that EI is a broader concept, it is not only focused on data analysis, but this is an area within EI.

WEB MINING. Web mining aims to discover useful information or knowledge (KNOWLEDGE) from the web hyperlink structure, page content, and user data. Although Web mining uses many data mining techniques, it is not merely an application of traditional data mining techniques due to the heterogeneity and semi-structured or unstructured nature of web data. Web mining or web mining comprises a series of techniques aimed at obtaining intelligence from data from the web. Although the techniques used have their roots in data mining or data mining techniques, they present their own characteristics due to the particularities that web pages present. OPEN DATA. Open Data is a practice that intends to have some types of data freely available to everyone, without restrictions of copyright, patents, or other mechanisms. Its objective is that this data can be freely consulted, redistributed, and reused by anyone, always respecting the privacy and security of the information. NATURAL LANGUAGE PROCESSING (NLP). From the joint processing of computational science and applied linguistics, Natural Language Processing (PLN or NLP in English) is born, whose objective is none other than to make possible the compression and processing aided by a computer of information expressed in human language, or what is the same, make communication between people and machines possible. PRODUCT MATCHING. Product Matching is an area belonging to Data Matching or Record Linkage in charge of automatically identifying those offers, products, or entities in general that appear on the web from various sources, apparently in a different and independent way, but that refers to the same actual entity. In other words, the Product Matching process consists of relating to different sources those products that are the same.
