These rules are mandatory, and testers must design or record tests without adhering to them. However, accessing an organized framework offers more benefits that professionals would miss out on otherwise. In this blog, we shed light on some of the prominent types of automated testing frameworks.

The Essence of Automated Testing Frameworks

Automated Testing Frameworks are designed to simplify the process of testing software applications. They provide a structured environment where test scripts can be executed and their outcomes evaluated without manual intervention. This approach reduces the effort involved in repetitive testing tasks, leading to increased efficiency and accuracy in the software development lifecycle.

Types of Test Automation Frameworks

Linear Scripting Framework

In a linear test automation framework, testers are not required to write code or generate functions. Moreover, the steps in it are written chronologically, and the process is also known as the record-and-playback framework. The tester records every step, like checkpoints, user input, navigation, etc., and then it is automatically played back to conduct the test. Considering there is no need for custom code, this framework can be executed without any expertise in test automation.

Advantages

• Simplicity and Clarity: Linear scripting is straightforward, making it easier to understand and follow. It's particularly beneficial for beginners or when a clear, unambiguous progression is needed.
• Predictability: Since the script follows a defined path, outcomes are predictable, which aids in planning and resource allocation. This predictability is essential in many programming and narrative contexts.
• Ease of Debugging: A straightforward flow makes identifying and fixing issues simpler. There are fewer variables and branching paths to consider for effectively streamlining the debugging process.

Disadvantages

• Lack of Flexibility: Linear scripting is often criticized for its rigidity. It doesn't easily accommodate changes or adapt to user inputs or scenarios.
• Limited User Engagement: In games and interactive media, linear scripting can lead to a less engaging experience, as it offers limited options and interactivity for the user.
• Predictability Can Be a Downside: While predictability is an advantage in some cases, it can also be a drawback. In narrative and game design, predictability can lead to boredom or a lack of challenge.

Modular Testing Framework

A modular testing framework requires testers to divide the application into separate testing categories like functions, units, sections, etc. Each of the classes is tested individually. Once the application is divided, testers create a test script for every part; they are then combined to create more extensive tests hierarchically. Additionally, the larger test sets work to represent different test applications. In the modular form of a testing framework, it is recommended to build an abstraction layer. This way, the sections won't influence the overarching module.

Advantages

• Reusability: By dividing tests into independent, reusable modules, the framework facilitates reusability, which can significantly save time and resources.
• Maintainability: Updates or fixes can be applied to individual modules without affecting the entire suite, enhancing maintainability.
• Scalability: The framework can easily accommodate or expand new tests, making it highly scalable.

Disadvantages

• Initial Setup Time: Setting up a modular testing framework can be time-consuming and requires careful planning.
• Complexity in Integration: Integrating different modules can sometimes lead to complexities, especially if the modules are not designed with integration in mind.
• Dependency Management: Managing dependencies between modules can be challenging and may require additional tools or strategies.

Library Architecture Testing Framework

The library architecture testing framework identifies similar tasks within the scripts and splits them into groups based on the function, rather than dividing the app under various tests. This allows the application to be grouped by the common objectives. Moreover, functions are stored in the library that they can access whenever needed.

• Possible Overhead: May introduce additional overhead in the development process, especially if it's too rigid or not well-integrated.
• Learning Curve: There's a learning curve for developers to understand and effectively use the framework, making the process complex.

Data-Driven Framework

The data-driven framework breaks up script logic and test data and allows the testers to store data in the framework externally. At times, testers need to test a particular feature or function at different times with multiple data sets. In such situations, testers cannot rely just on the data coded into the script. This framework allows the testers to store and pass various parameters to test scripts from different data sources like text files, excel spreadsheets, ODBC repositories, SQL tables, etc.
