What is a Test Automation Framework?

Test automation frameworks are a set of rules and corresponding tools that are used for building test cases. It is designed to help engineering functions work more efficiently.

The general rules for automation frameworks include coding standards that you can avoid manually entering, test data handling techniques and benefits, accessible storage for the derived test data results, object repositories, and additional information that might be utilized to run the tests in a suitable manner.

Advantages of using Test Automation Frameworks

The advantages of having test automation frameworks in check are as follows:

  • Reusability of Code

Since these frameworks come with the required coding data beneficial for the automation test to become a success, the valuable data is saved for future use and can be reused at any given point in time. There is no need to insert codes manually or rearrange them. The code can also be utilized to run other automation framework tests. The developed scripts can also be retained.

  • Low Cost

Test cases can be developed at a fairly low cost because the frameworks already have established rules. Also, given these codes can be reused multiple times, the cost and time of building test cases for new features are low.

  • Minimal Manual Interference

The automation frameworks run according to the guidelines that surround them. Since maximum coverage is already in-built and achieved at the initial stage, there is very little or no intervention required by individuals to run the automation tests. If the process fails, the automation frameworks can be run again with a little change, but the data remains constant and devoid of additional effort from an individual or team.

  • Improved Efficiency

Test automation frameworks increase productivity due to standardization. It guarantees maximum test coverage as the set of codes in a framework are executed in a standard manner from the beginning.

Types of Test Automation Frameworks

You can utilize one or more of the following automation frameworks for your tests. All these have been tried and tested and provide optimum results to ensure your tests are comprehensive:

  • Data-Driven Testing Framework

While testing an automation framework, a series of tests must be conducted before a successful outcome is derived. You might need to change the test data in such cases to try arriving at a different conclusion. The Data-Driven Testing Framework allows you the freedom to store the test data in an external drive, which can be accessed later to add a new script to the test case.

  • Keyword-Driven Testing Framework

Usually considered an extension of the data-driven testing framework, the keyword-driven testing framework not only extracts your test data to an external source but also safely maintains the set of codes. These codes are also referred to as ‘keywords’ and can be used to alter the test script to conclude further possible outcomes from the test framework. These keywords also essentially decide the functions performed by every application.

  • Hybrid Testing Framework

The hybrid testing framework combines the data-driven and keyword-driven frameworks to execute the most out of the aforementioned frameworks. It is the ideal automation framework, allowing more scope for increased productivity and better success.

  • Linear Scripting Framework

Unlike the above, Linear Scripting is carried out manually by an individual who records each and every step of the process. This framework is also known as the Record and Playback framework and takes up ample time to execute. It does not rely on automation expertise and might be a simple way to record a script, but it does not leave any space for script reuse. It also takes time for maintenance, and you would have to hand-code the test script in order to run the framework in the future.

  • Module-Based Testing Framework

As the name suggests, the Module Based Testing Framework requires the existence of various modules to run the framework. You would have to create separate scripts for every module and collaborate with them in order to generate the best results out of the automation test. The modules would not be affected if variations are made in how the application works. The scripts remain unharmed until one manually alters them. This offers a cost-efficient method of management since combining several modules creates a high level of modularization. Productivity remains at its peak. However, much time and effort can go into individually making changes to the test data in case there is a need.

Choosing among different types of frameworks is subject to the project requirements. However, no matter which test automation framework you decide to opt for, it is suggested to test on real devices for better test accuracy. Real device cloud like BrowserStack allows you to test under real user conditions, which will help identify the bottlenecks in the user experience.

BrowserStack gives you access to 3000+ real device-browser combinations that make testing thorough and accurate, with support for multiple frameworks like Selenium, Playwright, Cypress, etc.

Popular Examples of Test Automation Frameworks

Here are some of the top test automation frameworks used by developers across the globe:

Note: Tools mentioned below are in random order and not sorted by ranking. The article intends to help the organization choose the best framework that fits it, so the opinion is unbiased.

1. Selenium

selenium logo 1Selenium exist in the automation world for a long time. It is an open-source automation tool that makes test automation easy for modern web applications with the recent Selenium 4. Selenium 4 features consist of notable chrome CDP integration and many more to make testing efficient. That is why many QAs are upgrading from Selenium 3 to Selenium 4.

Components of Selenium Test Automation

  • Selenium IDE: Selenium IDE helps to record and play back your tests.
  • Selenium Grid: Helps to run tests across multiple machines parallelly.
  • Selenium WebDriver: Selenium WebDriver is most used and helpful in running the Selenium tests across the browser.
  • Selenium RC: Selenium RC helps write test cases in different programming languages to automate UI tests for web applications against any HTTP website. It is not much in use these days.

Selenium Data at Glance

  • Official Website: https://www.selenium.dev/
  • License: Apache-2.0 license
  • Github Data
    • Users: 147K
    • Contributors: 641
    • Stars: 23.9K
    • Forks: 7K

Advantages of Selenium

  • Selenium is an open-source tool that saves a lot of cost on license. 
  • Supports multiple programming languages such as Java, Javascript, C#, Python, Ruby, etc.
  • Supports all major browsers Chrome, Edge, Firefox, and Safari
  • Supports multiple operating systems Windows, Mac, and Linux-based OS
  • Strong community support, as Selenium is used by a large section of QAs worldwide.
  • Easy to learn and adopt.
  • Selenium supports Parallel Execution with Selenium Grid, reducing test execution time
  • Selenium is extensive, with many community plugins and packages available in the market.
  • Selenium framework can be extended to Mobile Testing.

Limitations of Selenium

  • Selenium provides high-level APIs, implementation is user-specific. Selenium is not ready to use the framework. This means that you need to set up a framework based on your need. If you are a beginner at automation testing, you may face difficulties setting up a robust framework.
  • No dedicated tech-support SLA is available, Since Selenium is open source you need to rely on community support. 
  • Selenium has Webdriver dependency as it works with browser-specific drivers (for example to run tests on chrome you need a chrome driver). This makes test execution slower and aligning browser and driver versions is difficult at times.
  • Dependency Management, as mentioned earlier selenium provides only high-level APIs to control the browser actions. For Assertions, Test environment configurations, and Reporting you need to rely on third-party packages. Which in turn increases the maintenance.
  • Problem with Modern Frameworks: Selenium might work very well with an application built with old-style architecture when it comes to modern web development frameworks such as React, Angular, Vue, etc. it might not work very great.
  • Selenium is not very aggressive in releasing features, unlike the modern test automation framework where it continuously listens to the user’s voice and implements new features and releases. Selenium releases are not very frequent.

There is no doubt that Selenium is the most popular tool in the test automation market. It is the best choice when your application is vast and has a mix of old and new technology. If your organization needs an automation framework that needs to be integrated with both the browser and mobile devices, then Selenium is likely preferred. 

As mentioned earlier, Selenium Framework needs maintenance, which means you need dedicated resources for automation testing. To leverage the best of Selenium Framework also requires an advanced level of coding experience, unlike any other framework. 

2. Cypress

Cypress frameworkCypress Logo has changed the automation mindset by providing rich features. It is one of the trending test automation tools in the market. Cypress is an Open Source Tool that also provides Cypress Dashboard as a professional service with the priced package.

Cypress provides developer-friendly features such as easy setup, installation, debugging, a dedicated Cypress window for running tests, etc.

Cypress Data at Glance

Advantages of Cypress

  • Cypress setup is really simple; once you install it’s ready.
  • Cypress Supports different types of Testing, Cypress supports Unit, Integration, Component, API Testing, and End to end Testing. 
  • Cypress Time Travel feature provides a snapshot of each test step.
  • Cypress records videos of your tests, you can configure the screenshot option as well.
  • No need to put waiting explicitly cypress waits automatically before performing any actions
  • Cypress tests are more reliable and faster there is no browser driver concept in cypress. Cypress directly interacts with the browser so tests are faster and more stable.
  • The Interactive Test Runner window in Cypress helps to faster development and debugging.
  • Cypress debugging is easy, since it provides multiple options to debug.
  • Well-structured documentation in Cypress makes it easy to learn new features and concepts. It’s helping especially if you are just started to build the Cypress test automation framework.
  • The Cypress community is growing so we can expect good community support in the future as well.

Limitations of Cypress

  • Cross-origin restriction: Cypress officially documented that it supports only the same origin URLs inside the test. For example, if your website has google authentication your website URL www.xyz.com redirects to signin.google.com. Since google.com is a different domain, Cypress doesn’t allow such redirecting. The suggested workaround is these sign-in should be handled programmatically. This is one of the main reasons why many organizations are still hesitant to adopt Cypress.
  • At this moment, Safari has not been supported. However, Cypress has a roadmap for supporting the Webkit (Open-source version of Safari) browser in the near future.
  • Cypress supports only JavaScript/Typescript programming language. Many test automation engineers are from Java or C# background since Cypress supports only JavaScript, the organization has to invest in updating its skillset.
  • Cypress doesn’t encourage page object patterns, though page object model can be achieved in Cypress to some extent Cypress doesn’t recommend it.
  • Using async/await in your Cypress test, the test might behave unexpectedly.
  • Parallel Testing setup is complicated in Cypress and not straightforward. 
  • Cypress doesn’t support multiple tabs and windows, again cypress suggests a workaround for this. Some organizations might require this feature but Cypress has mentioned this as the tradeoff
  • No Support for Native Mobile Application Testing
  • No direct support for the BDD framework like Cucumber
  • The complete automation framework requires a lot of things, such as reporting, and a variety of selector support, in Cypress most of the time you end up adding third-party packages, which increases the maintenance, and the framework becomes unstable gradually.

Considering the pros and cons of Cypress, Cypress is well suited for modern web applications such as React, Vue, Angular, etc. You can’t deny the fact that it is a developer-friendly tool. Cypress is aggressively delivering features but it has its limitation. Though, if you are familiar with Javascript you may miss the async/await in Cypress. Those familiar with Selenium might feel Cypress syntaxes are complicated. Some of the most used features, such as iFrame, multiple windows, and URLs from different origins, are limitations in Cypress. However, if these limitations are not a blocker in your organization and if you are looking more developer-friendly tool and a single framework for multiple types of testing then Cypress is the best tool.

3. Playwright

PlaywrightPlaywright Logo was launched in 2020, and within a few years, it has matured and attracted many users. This is because of their aggressive release strategy and well-documented code.

Playwright is an Open source tool, however, it is attached to the Microsoft brand. It is one of the pioneers in headless browser testing, which makes it popular.

Playwright Data at Glance

Advantages of Playwright

  • Playwright Supports multiple programming languages, such as Javascript/Typescript, Python, Java, C# (.Net)
  • Playwright supports multiple browsers such as Chromium, Firefox, Edge, Chrome, and Safari(Webkit releases only)
  • No Webdriver Dependency, since, Playwright directly executes the command on the browser. Thus, tests are comparatively faster and more stable.
  • Test Safari browser on Windows with Playwright. Usually, Safari browser can be tested only with macOS, but Playwright provides the windows patched WebKit version, which is more similar to Safari.
  • Playwright supports execution of tests on multiple browsers parallelly
  • All the selectors are supported by the Playwright
  • Playwright supports modern frameworks such as React, Angular, and Vue.
  • Playwright codegen is a test recorder for web tests, you can record the tests.
  • Playwright offers debugging tests in multiple ways. The tests can be debugged with Playwright Inspector, Playwright Trace Viewer​, Browser Developer Tools, Visual Studio Code debugger, Verbose API logs​
  • Support of multiple assertion libraries, by default playwright, comes with a Playwright test runner however you can configure it with Jest, Jasmine Mocha, etc.
  • Playwright encourages Page Object Model design pattern.

Limitations of Playwright

  • Though Playwright supports safari, it’s an open-source version which is WebKit, not the actual safari
  • It doesn’t support native mobile apps
  • Some users observed that some language bindings are not stable at a time
  • You can extend Playwright for Cucumber but there is no direct support. It can be done through third-party plugins or packages

Though Playwright is a new tool, it has a rich set of features, it supports multiple languages but the plan for language binding is still unclear. Playwright comes with its test libraries by default, so if you are planning to integrate other than default ones such as Jest, Jasmine, and Mocha you may need proficient knowledge in configuring them. If your organization is too much concerned about mobile native app testing Playwright has not started working on it. Playwright is the best choice with fewer limitations and supports all modern frameworks React, Angular, etc. However, ensure that the limitations are not major blockers to your organization’s requirements.

4. WebDriverIO

WebdriverIOWebdriverIO Logo is not a new framework and exists for a long time. WebdriverIO is somewhat similar to Selenium with JavaScript, as internally it uses Selenium libraries.

It is Open source and part of the OpenJS foundation.

 

 

WebdriverIO data at a glance

Advantages of WebdriverIO

  • WebdriverIO uses the Webdriver implementation so it supports all major browsers
  • Supports nearly 17 types of reporters, WebdriverIO supports multiple types of reporting
  • WebdriverIO is highly extensible there are many community-based plugins or packages which can be easily integrated into the framework and extend the features
  • WebdriverIO supports Page Object Pattern.
  • WebdriverIO supports multiple windows and tab 
  • There is no restriction for parallel testing.
  • WebdriverIO can be extended to Native Mobile application testing

Limitations of WebdriverIO

  • WebdriverIO uses its protocol bindings of Webdriver, which is again introducing one more layer. Though it supports chrome DevTools protocol for cross-browser testing you need to rely on Webdriver.
  • New releases need migration: Whenever WebdriverIO releases a new version, you must follow the migration guide to change the configurations.
  • Documentation: Though you can find documentation, you might feel it’s inadequate if you are a beginner
  • WebdriverIO supports javascript/typescript languages only
  • Framework setup may take some time based on your needs.

WebdriverIO is most suitable if you have proficient knowledge in Javascript, Since it is extensible you can build your robust framework using webdriverIO. However, considering their documentation and community support you may feel a little hassle while configuring the framework. There are community plugins you can just hook into your framework. A beginner might face difficulties or complicated ones as many things are bundled in one framework. The new version migration process adds to your framework maintenance task.

5. TestCafe

TestCafe LogoMany might not be heard of the name TestCafe, it is another NodeJS-based framework that supports Javascript/Typescript out of the box. TestCafe is a zero-configuration automation tool.

That means you can install and run your script just with a few commands.  TestCafe is an Open Source framework

 

TestCafe Data at Glance

Advantages of TestCafe

  • Easy to set up, You just need to install TestCafe, all the required features are installed and you are ready to start testing
  • TestCafe is shipped with a bunch of required features, typically no need to install additional dependency packages
  • Test creation in TestCafe is easy and more readable
  • TestCafe executes commands on the browser so tests are more stable and faster
  • TestCafe supports Multiple tabs or windows
  • TestCafe supports parallel testing
  • TestCafe supports all major browsers
  • Supports Page object patterns, Page Object Pattern can be designed using TestCafe

Limitations of TestCafe

  • Learning: You need to learn TestCafe syntax and API calls to use them
  • TestCafe Syntax is different from other JavaScript-based frameworks that are commonly used. 
  • TestCafe supports only Typescript/Javascript programming languages
  • TestCafe has its assertion libraries that you need to learn. Configuring third-party assertion libraries with TestCafe is not easy.
  • TestCafe supports CSS selectors only.

TestCafe is very good for beginners, as it has good documentation and everything shipped as part of their framework. However, it supports only Javascript/Typescript. TestCafe doesn’t provide customization as much as other testing frameworks. However, it is still extensible. While using TestCafe one might feel the difference while using the syntax, features,  and configurations.

6. NightwatchJS

NightwatchJSScreenshot 2022 07 18 at 3.08.56 PM is a NodeJS-based framework built with NodeJS that uses the Webdriver Protocol. Nightwatch is maintained by BrowserStack. Nightwatch can be used for End to End testing, API Testing, Unit testing, and Integration Testing using the combination of NodeJS services and NightWatchJS API.

  • No support for Native mobile apps.

NightwatchJS is evolving and adding new features so it’s worth considering. However, you must ensure the limitations are not a blocker for your organization. Since NightwatchJS is built on top of Selenium, complexities in Selenium still follow.

* We’re thrilled to announce that BrowserStack has acquired Nightwatch.js, to simplify your test automation efforts.

7. Appium

AppiumAppium Framework is an open-source test automation framework, that supports native mobile application automation. With Appium one can test  Android, iOS, and windows SDK native mobile apps. Appium comes with a good GUI which helps to inspect and efficiently write the code. 

Appium Data at Glance

Advantages of Appium:

  • Appium is an open-source library, saving costs for the license.
  • Cross-Platform Support Appium Provides cross-platform support for Safari on IOS and Chrome and in the built browser for Android, and the test works seamlessly across the devices.
  • Appium supports multiple programming languages such as Java, Ruby, C#, PHP, and Python

  • Integrating reports is difficult compared to other frameworks.
  • Appium supports only a newer version of Android  version below 4.2  is not supported
  • Appium’s support for the hybrid application is complicated; switching from a browser to a native app requires writing complex code

Appium is the most popular framework for mobile testing. However, the setup requires coding expertise. So the beginner might feel complicated. Appium can be integrated with Selenium, you can make the framework work across the computer and mobile seamlessly with the customized framework. If you already have a Selenium-based framework ready and looking for a tool to extend the framework for mobile applications, then Appium is the best choice.

8. Cucumber

CucumberCucumber Logo is an Open Source framework for Behavior Driven Development and Testing (BDD). Cucumber comes in various flavors, such as Cucumber for Java, Cucumber for Javascript, SpecFlow for C#, etc.

Cucumber is most popular because of its integration with different types of frameworks. Nowadays, almost all major automation frameworks support the Cucumber framework. Cucumber Tests are written in Gherkin language, which are called feature files, and the implementation is written in a step definition file.

Cucumber Data at Glance

Advantages of Cucumber

  • Easy to write the test, since it is in natural Gherkin language format.
  • The business teams can understand the features and test cases
  • High reusability can be achieved without technical knowledge
  • Easy to translate business requirements to test cases

Disadvantages of Cucumber

  • Cucumber is just a layer on top of your testing framework. Cucumber alone can’t be used for building a framework. So the testers must have skills in the TDD framework like Selenium and Cypress
  • Maintaining the Cucumber framework is difficult

There is no doubt that Cucumber is the best BDD Tool for testing, but implementation and maintaining the Cucumber framework is not easy as you think. The product team can easily understand the test cases and validate the requirements. Gherkin languages sometimes add a lot of complexity, especially when it comes to data-driven testing. Hence, it is essential to keep these contraints in mind and choose Cucumber for BDD Testing.

Bonus Test Automation Tools

9. Puppeteer Test Automation Libraries

Puppeteer is an open-source framework, managed by Google. Puppeteer is built with NodeJS and supports Javascript/Typescript programming languages. Puppeteer is shipped with Apache 2.0 License. Puppeteer is the best tool in terms of speed and stability but the main problem with Puppeteer is it officially supports only Chromium-based browsers. The firefox support for Puppeteer is still in an experimental state. Puppeteer provides a wrapper over Chrome DevTools protocol, you need to integrate assertion libraries such as Jest Mocha, etc.  Implementing a puppeteer requires good knowledge of Javascript programming language.

10. Katalon Studio Test Automation Tool

Katalon Studio is not an Open Source, however, it has a Free version, since many manual testers are considering it helpful due to its recording feature and hassle-free integration we are mentioning it here.  Katalon Studio supports Windows, macOS, and Linux-based systems. There are limited features available in Katalon Free version. Note that Katalon is a free tool, not an Open-source. Unlike open source project the feature, and restrictions are controlled by Katalon. It can change at any time.

11. Gauge Testing Framework

Gauge is an Open Source Test Automation framework, mostly used for Acceptance Testing. Gauge tests contain two files, the specification file which is similar to the feature file in Cucumber but the syntax will be different and the other file is the implementation file which is similar to the definition file in Cucumber. Gauge can be integrated with C#, Java, JavaScript ruby, etc. It is easy to Integrate with DevOps tool and also supports running parallel tests. However, as the userbase is less, the community support for the Gauge is considerably low.

Conclusion

It’s common to get confused when selecting the best test automation framework. Keep in mind that just because some framework is trending doesn’t mean it fits best into your organization. While selecting a framework you should always think about your current needs and future scope. The organization requirement plays a major role in selecting the best automation framework.

Though it might take some time to analyze and finalize the framework for your organization, it’s worth it if you compare it with the time taken to switch to another framework after a year. Switching to different frameworks from one is always risky and takes its own time. There is no such thing as the Best framework for the whole world but there is always the best framework for your organization so choose carefully. The best way to start the evaluation process is to gather requirements, understand the scope, do a smaller POC, and conclude your framework.

No matter which test automation framework you choose, it is highly recommended to run tests on real devices to take real user conditions into account while testing. With real device cloud like BrowserStack, you can test on 3000+ real device-browser combinations for a wide test coverage.
