When building serverless applications, you may encounter scenarios requiring AWS Lambda functions to be invoked across different AWS accounts. Cross-account Lambda invocation can be a powerful tool for organizations that manage multiple AWS accounts and want to facilitate secure and efficient inter-account communication. This article explores how to configure cross-account
In modern application development, invoking AWS Lambda functions is essential for various back-end tasks, from simple requests to complex data processing. While tools like Cypress are widely used for front-end testing, it can also be extended to test the integration of back-end services like AWS Lambda. In this article, I’
In the complex world of software development, ensuring quality is crucial. QA professionals rely on a trio of testing techniques: smoke, sanity, and regression. While these terms might sound similar, each serves a unique purpose in the software development lifecycle. Let’s explore these essential quality assurance methods. Smoke Testing:
In an age where technology is rapidly advancing, it's easy to overlook the value of manual testing. Yet, as software development evolves, the role of manual testers remains crucial. Often seen as a lesser discipline, manual testing is, in reality, the backbone of quality assurance (QA) that can
In today's world, ensuring data security is critical for any application. AWS Key Management Service (KMS) provides a simple way to encrypt and decrypt sensitive data. In this post, we'll cover how to use AWS KMS for encrypting and decrypting data, including steps to create a
In the agile era, where iterative development and continuous feedback are paramount, the traditional approach of waiting until the testing phase to uncover and fix software errors is increasingly seen as inefficient. Agile methodologies emphasize early and frequent testing, collaboration, and incremental improvements. Here's why waiting until testing
In modern web applications, handling images efficiently is crucial, whether you're building e-commerce platforms, content-sharing sites, or any other service where images are prevalent. One of the most powerful tools for image processing in Node.js applications is the Sharp library, known for its performance and versatility. Coupling
When performing automated tests or making repeated network requests, it's crucial to implement a strategy that prevents overwhelming the server and ensures efficient retries in case of transient failures. One effective approach is the exponential backoff algorithm. This guide will explore how to implement the exponential backoff algorithm
The Test Pyramid is a powerful concept in software development that helps teams allocate their testing efforts efficiently. It emphasizes the importance of a strong foundation of unit tests, complemented by a smaller number of more complex tests at higher levels Unit and integration level tests * API-based tools. System and
Testing is a crucial aspect of software development that ensures the product meets the desired quality and performance standards. In Agile development, Brian Marick's testing quadrants framework offers a comprehensive approach to categorizing and managing tests. This model helps teams visualize and implement a variety of test types
Uploading files to an SFTP server is a critical part of many applications. This guide will walk you through the process using Node.js and Cypress, leveraging the ssh2-sftp-client library for handling SFTP connections and file transfers. What is SFTP? SFTP (SSH File Transfer Protocol) is a secure method for
When dealing with a large number of data records in DynamoDB, it’s crucial to handle the operations efficiently to avoid errors and throttling. One effective way is to use the DynamoDB batch write operation. This post will guide you through the process, including handling retries for common errors using
