Which One Gives You Higher ROI: API Automation or UI Automation?

Aggregated on: 2023-06-19 16:45:56

In the world of software testing, organizations are continually seeking ways to optimize their testing processes, improve efficiency, and enhance overall product quality. One effective strategy gaining traction is shifting the testing focus from User Interface (UI) automation to Application Programming Interface (API) automation. This shift brings numerous advantages, including faster execution, increased test coverage, improved stability, enhanced reusability, earlier bug detection, and improved maintainability. Let's delve deeper into how emphasizing API automation can significantly enhance testing efficiency. Faster Execution: API automation tests outpace UI automation tests in terms of speed. By eliminating the need for rendering and interacting with UI components, API calls are lighter and execute more swiftly. Consequently, this leads to shorter test execution times, facilitating quicker feedback cycles and expediting the overall testing process. Increased Test Coverage: APIs expose a broad range of functionalities and endpoints that can be independently tested. By shifting the focus to API automation, testers can achieve comprehensive coverage of the application's functionality. This includes testing scenarios that may be challenging to replicate or test solely through the UI. As a result, the testing efforts become more thorough, uncovering potential issues that could have been overlooked by relying solely on UI automation. Improved Stability and Reliability: UI automation tests often suffer from fragility due to UI layout changes, CSS modifications, or browser-specific issues. Conversely, API automation focuses on the backend functionality, which tends to be more stable. By relying more on API automation, testing efforts become more resilient to UI changes, resulting in improved stability and reliability of the tests. This stability allows testers to focus on true application behavior rather than being distracted by superficial UI changes. Enhanced Reusability: APIs provide standardized interfaces for interacting with applications, enabling the creation of reusable automation code. With well-designed API automation frameworks, testers can build libraries and modules that can be easily leveraged across multiple test scenarios and even different applications with similar APIs. The reusability of API automation code significantly reduces redundancy, effort, and maintenance costs associated with UI automation scripts. Earlier Bug Detection: API testing can be initiated at an early stage of the development process, as APIs are often available before the full UI implementation. By shifting the testing weight towards API automation, organizations can identify and rectify issues related to data validation, request/response handling, and business logic earlier in the development cycle. Detecting bugs at an early stage reduces the likelihood of these issues cascading to the UI layer, saving time and effort in later stages. Improved Maintainability: Maintaining UI automation tests can be challenging, particularly when the UI undergoes frequent changes. UI modifications often require corresponding updates to test scripts, leading to increased maintenance efforts. By emphasizing API automation, which is less affected by UI changes, organizations can achieve a more stable and maintainable test suite. This streamlined maintenance process allows testers to focus on actual functional changes rather than constantly updating UI automation scripts. Conclusion The paradigm shift towards emphasizing API automation in software testing offers a multitude of benefits, including faster execution, increased test coverage, improved stability and reliability, enhanced reusability, earlier bug detection, and improved maintainability. By leveraging the power of APIs, organizations can optimize their testing processes, allocate resources more efficiently, and deliver higher-quality software products. Striking the right balance between UI automation and API automation will enable testing teams to achieve comprehensive and efficient testing, resulting in robust and reliable applications.

Microservices With Apache Camel and Quarkus (Part 4)

Aggregated on: 2023-06-15 18:00:53

As we've seen previously, running our microservices in JVM mode means packaging and running them as executable JARs. But Quarkus also allows us to compile them into machine code and run them as native processes. This has the advantage of dramatically improving the application start-up time and memory usage. Hence, the native mode is the preferred execution mode of the Quarkus applications in production. All the whys and wherefores of the native mode are explained in a very clear and detailed manner in the Quarkus documentation. To resume, in order to compile Java code into machine one, a so-called "C native compilation environment" is required, as well as a GraalVM distribution. However, given the relative complexity of the GraalVM installation and configuration process, Quarkus is able to avoid it to us and offers the possibility to create Linux executable code without having to install and configure GraalVM. This is the modus operandi that we'll be adopting here.

Low Overhead Continuous Contextual Production Profiling

Aggregated on: 2023-06-15 16:30:53

In the realm of production applications, it is customary to address performance bottlenecks such as CPU and memory issues in order to identify and resolve their underlying causes. In order to gain insight into these problems, we gather a range of metrics and logs to monitor the utilization of system resources such as CPU, memory, and application-specific latencies. It is worth noting that this data collection process does not impact the performance of the application. However, it does not provide visibility into the operations taking place at the code level, such as method, socket, and thread states. Moreover, the process of collecting these profiles introduces overhead during application runtime and necessitates the storage and visualization of significantly large datasets.

Aggregated on: 2023-06-15 16:30:53

About OpenAPI It is a specification that allows to describe REST API in a standard way. The OpenAPI Specification (OAS) defines a standard, programming language-agnostic interface description for REST APIs. This allows both humans and computers to discover and understand the capabilities of a service without requiring access to source code, additional documentation, or inspection of network traffic. About Swagger Swagger is a set of open-source tools built around the OpenAPI Specification that can help software professionals design, build, document, and consume REST APIs. Where OpenAPI deals with specification, Swagger implements the specification to describe a REST API .

In this article, we will discuss what challenges Salesforce presents for quality engineering and how we can leverage a low code/no code approach for automation testing in Salesforce. First, let's have a look at what are prime challenges salesforce presents due to its highly dynamic nature.

Waterfall Software Development

Aggregated on: 2023-06-15 15:30:53

What Is Waterfall Software Development? Waterfall software development is a traditional project management approach that follows a linear and sequential process. It is characterized by distinct phases, with each phase being completed before the next one begins. The approach gets its name from the cascading flow of activities from one phase to another, much like a waterfall. Some Typical Phases of the Waterfall Software Development Model Requirements Gathering: In this phase, the project requirements are gathered and documented. This involves understanding the client's needs, identifying project goals, and creating a comprehensive requirements document. Framework Plan: When the necessities are laid out, the framework configuration stage starts. This involves creating a detailed system architecture and design based on the gathered requirements. The design includes software modules, data structures, user interfaces, and any other relevant components. Implementation: In the implementation phase, the development team starts coding and programming based on the system design. Each module is developed and integrated into a complete software system. Testing: After the software is implemented, it undergoes testing to identify and fix any defects or issues. Testing incorporates unit testing, mix testing, framework testing, and client acknowledgment testing. This phase aims to ensure that the software functions as intended and meets the specified requirements. Deployment: Once the software has passed testing and received approval, it is deployed to the production environment or delivered to the client. This phase involves installation, configuration, and making the software available for end-users. Maintenance: After organization, the product enters the upkeep stage. This involves ongoing support, bug fixes, updates, and enhancements based on user feedback and changing requirements. The waterfall model emphasizes a structured and sequential approach, where each phase has well-defined inputs and outputs. It is suitable for projects with stable and clearly defined requirements, where changes are less likely to occur. However, it has limitations in accommodating changes during development, as the next phase cannot begin until the previous one is completed.

Playing With WASM on Docker

Aggregated on: 2023-06-15 14:45:53

The idea of a bytecode that can run anywhere dates back to the JVM inception (as far as I know). WebAssembly is the new implementation of an old idea. While WebAssembly is meant to run in the browser, Docker recently announced its capability to run WASM code without needing containers. In this post, I want to explore how it can work. Prerequisite Running WebAssembly is a beta feature and requires using containerd. To enable containerd, go to the Docker Desktop dashboard, then Settings > Features in development > Beta features > Use containerd for storing and pulling images.

Recently I was given the task of refactoring and reimplementing the service, which determines the users' authorizations within our SaaS application. The major challenge was to do the work without anyone realizing it: the charade is up once errors start popping and paying customers have difficulties doing their job. Worst possible end-case: users are completely blocked from accessing the app, and customers flee to your competitors. No pressure, right?

Agile Development Tutorial: Comprehensive Guide With Best Practices

Aggregated on: 2023-06-15 14:00:53

An Agile development approach emphasizes the quick and frequent delivery of quality software products through an iterative and incremental process. Based on the Agile Manifesto, Agile development prioritizes customer interaction, working software, and customer collaboration in Software Development Life Cycle. Software projects could be definable work or work with high uncertainty. A set of clear procedures that have proven successful in previous similar projects characterizes a definable work project. Because high-uncertainty projects have increased risk and high complexity, they can be challenging for traditional methods that aim to anticipate most requirements and drive any change through the change request process.
