The progression of automation in the realm of software testing has brought about a transformative expedition that has had a profound impact on the effectiveness and dependability of software development procedures. At the outset, testing predominantly relied on manual efforts, which were characterized by practices that consumed a significant amount of time and were prone to errors. However, the advent of automation tools in the latter part of the 20th century marked a notable shift, enabling testers to automate repetitive tasks and execute test scripts.
During the initial stages of automation, scripted testing was introduced, wherein testers possessing programming skills would meticulously create scripts that imitated user interactions. As the necessity for scalability and maintainability grew, methodologies such as keyword-driven and data-driven testing emerged, abstracting test scripts from the underlying code.
The implementation of test frameworks, such as J Unit and N Unit, introduced a structured approach to organizing and executing automated tests. Additionally, Behavior-Driven Development (BDD) methodologies like Cucumber further enhanced collaboration among teams by using natural language to express tests [1]. With the advent of DevOps practices, automation became an integral part of continuous integration and continuous testing pipelines. Recent advancements in artificial intelligence and machine learning have introduced intelligent testing solutions that are capable of independently generating and executing test cases.
In the most recent phase, there has been an emergence of lowcode and no-code testing solutions, which empower individuals with limited coding expertise to actively participate in the testing process. This ongoing evolution is a testament to the commitment towards efficiency, collaboration, and adaptability in the everchanging landscape of software development.
Traditional automation in software testing refers to the conventional practice of utilizing scripts or code, commonly written in programming languages such as Java, Python, or C# to mechanize test scenarios. This approach entails the creation of comprehensive scripts that interact with the application being tested, simulating user actions and validating anticipated outcomes [1]. The utilization of traditional automation necessitates a solid foundation in programming and scripting languages, rendering it suitable for skilled developers and testers. Despite offering considerable flexibility and customization, this method may require a greater investment of time and resources in comparison to emerging methodologies like low-code or no-code automation.
Low-Code Automation is a testing methodology that optimizes the process of test creation by minimizing the need for manual coding. By utilizing visual interfaces, pre-designed components, and dragand-drop functionalities, it enables testers to design and executetests with reduced reliance on conventional coding skills [2]. This approach significantly expedites the test development lifecycle, making it accessible to a wider range of professionals, including those without extensive coding expertise. Low-Code Automation enhances efficiency and collaboration by democratizing the testing process, enabling teams to create and maintain automated tests more swiftly and effectively compared to traditional coding-centric approaches [3].
No-Code Automation presents a ground-breaking methodology for testing that eliminates the need for manual coding entirely. Through the utilization of intuitive visual interfaces, drag-and-drop components, and pre-configured elements, testers and non-technical users alike are able to construct automated test scenarios. The primary focus of No-Code Automation lies in its emphasis on simplicity and accessibility, enabling a wider range of professionals to actively engage in the test automation process without possessing traditional coding skills. This democratization of testing not only enhances collaboration, but also expedites the test development lifecycle by facilitating the swift and efficient creation of automated tests, thereby rendering the entire process more comprehensive and user-friendly.
