If you are working in QA and getting familiarized with automation testing, you might have brief knowledge about the automation frameworks. But how much do you know about these frameworks in detail?

Automation testing revolves around automation frameworks. This is your chance to get to know about these in depth. 

Introduction to Automation Frameworks

Automation Testing frameworks are critical components of any effective automated testing process. 

They can minimize maintenance expenses and testing efforts while also providing a greater return on investment (ROI) for QA teams aiming to improve their agile procedures.

The purpose of this guide is to walk you through the most prevalent types of frameworks employed today, as well as their merits and downsides. 

For QA professionals who are new to automated testing or need a fast reminder, this article will give a high-level overview of every sort of framework along with how they might contribute to the efficacy of any automated testing procedure.

What is a Testing Framework?

A testing framework is a collection of instructions or standards for developing and designing test cases. A framework is a collection of methods and tools intended to assist QA professionals test faster.

These guidelines could include coding standards, test-data processing methods, object repositories, mechanisms for storing test results, or instructions on how to access other resources.

While these are not necessary principles, and testers can script or record tests despite adhering to them, adopting an organized framework often gives additional benefits that might otherwise be overlooked.

What are the Types of Automation Frameworks?

Test automation frameworks has the following types;

Linear Automation Framework

The linear automation framework is often used in the testing of very small applications. This framework is also known as the Record and Playback Framework.

The Linear Automation Framework, also referred to as the Record-and-Playback Framework, is the most fundamental and basic sort of automation framework. 

This entails recording user activities and playing them again during test execution.

Advantages	Disadvantages
Easy to learn and use	Limited reusability and scalability
Suitable for small projects	Difficult to maintain
Requires minimal programming skills	Not suitable for complex applications

Modular-Based Automation Framework

In this Framework, the tester can construct test scripts module by module, breaking down the entire application into smaller modules based on the client’s needs and creating test scripts separately.

The Modular-Based Automation Framework breaks down the app into smaller, reusable pieces. Each module can be evaluated independently, allowing teams to increase productivity and reusability.

Advantage	Disadvantage
High reusability and scalability	Requires more programming skills
Improved maintainability	Higher initial setup cost
Suitable for large projects	More complex than the Linear Automation Framework

Library Architecture Testing Framework

A library architecture test framework finds tasks that share similarities inside the test script. After that, testers categorize related tasks by function. 

A library then holds all of the sorted functions. As a result, it makes code more reusable across multiple test scripts.

The Library Architecture Testing Framework entails building a collection of reusable functions and methods. These routines can be called during test execution, allowing teams to increase efficiency and reuse.

Advantage	Disadvantage
High reusability and scalability	Requires more programming skills
Improved maintainability	Higher initial setup cost
Suitable for large projects	More complex than the Linear Automation Framework

Data-Driven Framework

Typically, test data is read from external files such as Excel files, text files, CSV files, ODBC sources, and DAO objects and loaded into variables within the test script. Data-driven architecture enables us to write test automation scripts that pass various sets of test data.

The Data-Driven Framework separates test data from test scripts. This allows teams to evaluate the exact same script with diverse data sets, increasing test coverage while lowering testing time and effort.

Advantage	Disadvantage
High test coverage	Requires more programming skills
Improved efficiency and reusability	Higher initial setup cost
Suitable for large projects	More complex than the Linear Automation Framework

Keyword-Driven Framework

The Keyword-Driven Testing framework is also known as table-based testing. This framework is only appropriate for smaller projects or apps. 

The automation test scripts are based on the keywords given in the project’s excel sheet. 

The Keyword-Driven Framework entails constructing a table of phrases or actions that can be carried out during test execution. 

This allows teams to write test scripts in a simple, straightforward language, which saves time and effort during testing.

Advantage	Disadvantage
Easy to learn and use	Requires more programming skills
Suitable for non-technical team members	Higher initial setup cost
Improved reusability and scalability	More complex than the Linear Automation Framework

Hybrid Testing Framework

The Hybrid Testing Framework combines the capabilities of numerous frameworks, allowing teams to improve efficiency, reuse, and scalability.Most hybrid frameworks are used to combine the advantages of keyword-driven and data-driven frameworks.

Advantage	Disadvantage
High reusability and scalability	Requires more programming skills
Improved maintainability	Higher initial setup cost
Suitable for large projects	More complex than the Linear Automation Framework

Behavior-Driven Development Framework

The Behavior Driven Development framework is a framework that fosters active participation from project stakeholders such as developers, testers, and business analysts. 

It focuses on defining the behavior of applications from the user’s point of view, allowing teams to write test scripts that are more in line with user demands and expectations, thereby enhancing the program’s quality.

Advantage	Disadvantage
Improved user experience	Requires more programming skills
Improved collaboration between team members	Higher initial setup cost
Suitable for agile development methodologies	More complex than the Linear Automation Framework
