This article will give you all you need about test automation frameworks, including their benefits and types, examples, and how to choose the right one.
Testing frameworks are a crucial part of an effective automated testing procedure. They can cut costs for maintenance and testing and give QA teams that want to improve their agile processes a higher return on investment (ROI).
No longer do organizations rely entirely on manual testing. Manual testing has benefits and drawbacks, but it is still necessary, and it's laborious, time-demanding, and requires substantial financial and human effort.
This article will give you all you need to know about test automation frameworks. To further understand test automation frameworks and their component units, read on. Understanding the value of test automation frameworks and how to pick the right one is also covered. This is a brief overview of the topics we'll be discussing today:
Let's define a test automation framework before discussing the most popular frameworks and their advantages. A testing framework is a collection of principles or standards to create and design test cases. A framework is a set of procedures and resources for quality assurance that work together to improve testing effectiveness.
Coding standards, test data handling techniques, object repositories, protocols for storing test findings, and access to external resources are all examples of what can be covered by such guidelines.
Do you think you can automate a test WITHOUT a framework?
The answer is YES! Of course, you can automate a test without these guidelines.
Even though these guidelines are optional and testers can still script or record tests without adhering to them, employing a structured framework frequently provides testers with additional benefits that they would otherwise lose.
The purpose of frameworks is to offer a common structure so that developers can reuse the given code without having to recreate it from scratch. With the help of frameworks, we can avoid unnecessary work and speed up the process significantly.
Every automation framework has its structure, features, and potential drawbacks. It is crucial to pick the appropriate framework while developing a set of tests. These frameworks include:
Let's take a closer look at each of these.
Linear test automation frameworks allow testers to design functions without writing any code, and the steps are recorded and played again in a predetermined order. With this method, the tester documents the procedure, noting any navigation, user interaction, or checkpoints, and then plays back the script to execute the test automatically.
To use a modular framework, testers will have to break the application they are testing into separate units, functions, or sections and test each separately. After breaking the application into modules, a test script is made for each part. These scripts are then put together in a hierarchical way to make bigger tests, and these bigger groups will start showing different test cases.
Building an abstraction layer is a key part of using the modular framework so that changes to individual parts don't affect the whole.
The modular framework is the basis for the library architecture framework for automated testing, but it has some extra benefits. Instead of splitting the program under test into the many scripts that must be executed, related jobs inside the scripts are recognized and subsequently grouped by function so that the application is eventually divided by common goals. These functions are kept in a library that the test scripts can use whenever necessary.
Using a data-driven framework separates the test data from the script's logic, which lets testers store data outside of the framework. The requirement to re-test the same feature or function of an app with new data comes up regularly for testers. In these cases, a Linear or Modular testing framework would be inappropriate since the test data would be hard-coded in the script.
The tester can keep the input/output parameters for test scripts in an external information source such as an Excel spreadsheet, Text File, CSV file, SQL Table, or ODBC repository by establishing a data-driven test framework.
The external data source is linked to the test scripts, and the scripts are told to read and fill in the needed data when needed.
The keyword-driven testing framework, usually considered an expansion of the data-driven testing framework, does more than simply export your test data to a separate location; it also reliably stores the resulting code library. These symbols, also known as "keywords," can be used to modify the test script and draw further conclusions about the test environment. It is also true that any program's functionalities are largely determined by the keywords used to describe them.
Like other modern testing procedures, automated testing frameworks have begun to merge and overlap. A hybrid framework, as the name indicates, is one that takes elements from more than one of the types above frameworks and combines them in such a way as to maximize the strengths while minimizing the drawbacks.
Testing methods should also vary depending on the type of application being evaluated. Setting up a versatile framework for automated testing is essential, especially as more teams adopt the agile methodology. Best test results may be achieved using a hybrid framework since it is more flexible.
Now that you know what test automation frameworks can do for you, it's time to decide which one to use.
With so many testing frameworks, knowing which is best for you can be hard. And to find the best solution, you must first know your needs. Before you try to find the best testing framework, you should know the basics of your testing process:
Here are some of the best frameworks for test automation that developers around the world use:

Selenium is an open-source automation tool that makes test automation easy for modern web applications.
Recently, Selenium 4 has Chrome CDP integration and many more to make testing efficient. That is why many QAs are upgrading from Selenium 3 to Selenium 4.
Playwright came out in 2020, and in just a few years, it had grown and gained many users. This is because of how quickly they release updates and how well their code is explained. It is an open-source tool, but it is linked to the Microsoft brand. It was one of the first to test browsers without a user interface, which makes it popular.
The Appium Framework is a free, open-source tool for testing mobile apps written in Java in an automated way. Users can test native mobile apps made with Android, iOS, and Windows SDKs with Appium. Appium has a useful graphical user interface (GUI) that facilitates code inspection and rapid development.
Integrating easily into several frameworks is a major selling point for Cucumber. The Cucumber framework is widely adopted nowadays and supported by the most popular automation frameworks. Feature files, written in the Gherkin language, describe the tests themselves, while the implementation is described in a step definition file.
Using the Webdriver Protocol, NightWatchJS is a NodeJS-based framework that helps you test your code. BrowserStack is responsible for Nightwatch maintenance. Using the combination of NodeJS services and the NightWatchJS API, Nightwatch can be used for API testing, End to End testing, integration testing, and unit testing.
