The Definitive Guide to TDD in React: Writing Tests That Guarantee Success

Aggregated on: 2024-06-20 15:36:25

Imagine coding with a safety net that catches errors before they happen. That's the power of TDD. In this article, we'll dive into how it can revolutionize your development workflow. In Test Driven Development (TDD), a developer writes test cases first before actually writing code to implement the functionality. There are several practical benefits to developing code with the TDD approach such as: Higher quality code: Thinking about tests upfront forces you to consider requirements and design more carefully. Rapid feedback: You get instant validation, reducing the time spent debugging. Comprehensive test coverage: TDD ensures that your entire codebase is thoroughly tested. Refactoring confidence: With a strong test suite, you can confidently improve your code without fear of breaking things. Living documentation: Your tests serve as examples of how the code is meant to be used. TDD has three main phases: Red, Green, and Refactor. The red phase means writing a test case and watching it fail. The green phase means writing minimum code to pass the test case. The refactor phase means improving the code with refactoring for better structure, readability, and maintainability without changing the functionality while ensuring test cases still pass. We will build a Login Page in React, and cover all these phases in detail. The full code for the project is available here, but I highly encourage you to follow along as TDD is as much about the process as it's about the end product.

Load Testing Made Easy: A Comprehensive Introduction

Aggregated on: 2024-06-19 15:51:22

What Is Load Testing? Load testing is also termed reliability testing or software performance testing. It is a software testing method where the software or an application is put through an abnormal load to see how it reacts and performs under that condition. It is thoroughly checked if the performance of the application decreases or increases in that situation. The main aim of running a load test is to detect the potholes in an application’s performance and smoothness. This ensures that stability is instilled into that software when multiple users access the same function simultaneously. The biggest USP of Load Testing is that it helps in giving out a clearer picture of the limitations of the application. Then, enabling enables the tester to analyze the root cause of the problem and take corrective measures. Through load testing, the failures are limited during production, which in return reduces the expenses. Hence, load testing is very cost-effective in nature.

Ideal Generative AI vs. Reality Foundational LLMs have read every byte of text they could find and their chatbot counterparts can be prompted to have intelligent conversations and be asked to perform specific tasks. Access to comprehensive information is democratized; No more figuring out the right keywords to search or picking sites to read from. However, LLMs are prone to rambling and generally respond with the statistically most probable response you’d want to hear (sycophancy) an inherent result of the transformer model. Extracting 100% accurate information out of an LLM’s knowledge base doesn’t always yield trustworthy results. Chat LLMs are infamous for making up citations to scientific papers or court cases that don’t exist. Lawyers filing a suit against an airline included citations to court cases that never actually happened. A 2023 study reported, that when ChatGPT is prompted to include citations, it had only provided references that exist only 14% of the time. Falsifying sources, rambling, and delivering inaccuracies to appease the prompt are dubbed hallucination, a huge obstacle to overcome before AI is fully adopted and trusted by the masses.

Spring Boot Actuator comes with various health indicators for most relational databases and non-relational databases like MongoDB, Redis, ElasticSearch, etc. Spring Boot Actuator also provides health indicators for RabbitMQ, and IBM MQ out of the box. Why Choose Custom Health Checks If we want to monitor the health status of the external services our application connects to, Spring Boot doesn’t provide any health indicators for this scenario out of the box, we need to write custom health indicators. Also, Spring Boot doesn’t provide any Kafka health indicator out of the box as of today, so in this scenario, we need to go for a custom health indicator.

I bet you might have come across a scenario while automating API/web or mobile applications where, while registering a user, you may be setting the address for checking out a product in the end-to-end user journey in test automation. So, how do you do that?

Beyond Sessions: Centering Users in Mobile App Observability

Aggregated on: 2024-06-14 23:36:15

Observability providers often group periods of activity into sessions as the primary way to model a user’s experience within a mobile app. Each session represents a contiguous chunk of time during which telemetry about the app is gathered, and it usually coincides with a user actively using the app. Therefore, sessions and their associated telemetry are a good way to represent user experience in discrete blocks. But is this really enough? Is there a better way to understand the intersection of users, app behavior, and the business impact of app performance?

Border Gateway Protocol is a routing protocol used to form communication between different Autonomous Systems on the internet. BGP works over a TCP connection and goes through multiple steps to establish and maintain a session. Let's dive in to understand it. Topology:

The Keyword-Driven Test Automation Framework With JSON Format for REST API Testing

Aggregated on: 2024-06-14 21:21:16

First, I’d like to get back a little bit of this framework’s architecture overview. Test Execution Progress As the above image and the previous story mentioned, the test suites/cases/steps are formed in a JSON file, and the framework will load and map these JSON files to the list of test suites/cases objects. Then, action steps are executed based on the class and method (keyword) that are specified in each test step (use the reflection technique to invoke the keyword — method). Our responsibility is to write the autotest script inside each keyword.

Ordering Chaos: Arranging HTTP Request Testing in Spring

Aggregated on: 2024-06-14 19:51:15

In this article, I would like to describe an approach to writing tests with a clear division into separate stages, each performing its specific role. This facilitates the creation of tests that are easier to read, understand, and maintain. The discussion will focus on using the Arrange-Act-Assert methodology for integration testing in the Spring Framework with mocking of HTTP requests to external resources encountered during the execution of the tested code within the system behavior. The tests under consideration are written using the Spock Framework in the Groovy language. MockRestServiceServer will be used as the mocking mechanism. There will also be a few words about WireMock.

The Future of Mobile Observability Is OpenTelemetry

Aggregated on: 2024-06-14 18:21:15

OpenTelemetry is built on the premise of transparent, portable, and extensible data collection. While these practices are changing the way development teams work for server-side infrastructure and application monitoring, these same principles have not been realized for the client-side layer, often labeled "RUM" in legacy terminology. But that’s changing rapidly.

Levelling Up: The Non-Technical Skills Every Aspiring Senior Engineer Needs

Aggregated on: 2024-06-14 16:36:14

As a software developer, the path toward becoming a senior engineer can seem deceptively straightforward — keep learning new technologies, master coding languages, and dive deeper into software architecture and design patterns. However, the reality is that reaching the senior level requires more than just technical prowess. It demands a well-rounded skill set that extends far beyond coding abilities. The Importance of Soft Skills While technical competency is undoubtedly crucial, many experienced developers often overlook the significance of soft skills in their pursuit of career advancement. These non-technical abilities are the glue that holds teams together and enables effective collaboration, communication, and problem-solving.

Building an Internal TLS and SSL Certificate Monitoring Agent: From Concept to Deployment

Aggregated on: 2024-06-14 15:51:18

Can you monitor your internal SSL certificates? This was a question we frequently heard from our clients. Many organizations keep their services (web, database, etc.) inaccessible on the public internet, for security, compliance, cost, and other reasons. At TrackSSL, we initially offered public SSL/TLS certificate monitoring, but we often received requests from customers for private SSL certificate monitoring. Thus, we needed to find a way to monitor certificates used on servers that are not typically accessible from the Internet. In this article, we share our journey of developing a remote certificate monitoring service using an agent that runs on an organization's private network. We share the requirements we defined, the architecture we selected, and the solution we implemented.
