Drawing on the experience in test automation of our QA consultants and engineers, ScienceSoft has compiled a list of popular tools for building a test automation toolkit in 2022. The list includes various categories of automated testing tools and tools related to all other aspects of test automation. We have employed them in our practice or see as particularly promising and winning the trust of the test automation community.

Testing via UI

In testing via UI, the automation testing tools can be categorized into the following fields:

UI automation tools

These tools help to check UI components and an application’s end-to-end functionality by mimicking the actions of a user in a browser – clicking a button, switching a page, entering symbols into a field and more.

  • Selenium WebDriver 3.0

In the pool of automated testing tools for web testing via UI, Selenium is the core one. It is an open-source and platform-independent tool, which supports test automation for all major web browsers. Since Selenium is basically a set of APIs, it provides a flexible and scalable way to test web applications. However, Selenium requires good programming skills to install, integrate and work with other tools.

  • UFT

UFT is the most popular tool among commercial alternatives to Selenium. It is a robust, user-friendly test automation tool by Micro Focus (now, part of HPE Software). UFT is easy to install, has rather good in-built reporting, and in addition to web testing, supports mobile, desktop, API/web service and database testing. At the same time, UFT-based test automation has several important limitations. It runs in Windows environments only and uses the Visual Basic language for scripting.

Other options: Protractor, Katalon, Ranorex, Robot Framework, TestComplete, Cypress, Nightwatch.js, Puppeteer, Serenity.

Visual validation tools

Visual testing tools take a screenshot of the UI in the testing process and compare it with a previously stated reference template. These test automation tools mostly help check for visual bugs, such as the wrong size, layout, or color of visual elements, overlapping visual components, incorrect/missing images and icons, but can also be used to check functionality. Screenshot-based automation can be easier and faster than pure scripting.

  • Applitools

Applitools is leading the way in visual testing automation. In addition to powerful AI-driven testing capabilities that allow ignoring non-critical inconsistencies in UI visuals, Applitools offers parallel test execution, both on-premises and cloud-based runs and concise testing reports. It integrates with popular CI tools (Jenkins, Travis CI, CircleCI, and others), Jira (issues can be created and managed directly from the Applitools test manager) and Azure DevOps Server. However, Applitools is free for open-source projects only.

Other options: Screenster, Eggplant AI, Percy, Happo.

Snapshot testing tools

These test automation tools help exclude unintended changes in the user interface much faster and report them to the developers easier than with screenshot testing. They capture a complete UI structure of an element stored within text files and compare it with a pre-stated standard using a diff algorithm.

  • Jest

Jest is currently an open-source fully featured test automation framework designed by Facebook to test any JavaScript application, and it is especially widely used with React.js applications. High performance is the focus of Jest-based testing. The framework achieves this via parallel tests, isolation of tests in their own processes as well as running previously failed tests first and more.

Other options: Ranorex.

Assertion libraries

They help verify that UI components (fields, titles, popups, texts and buttons) are correct. Some test automation frameworks (Jasmine, Jest) have them in-built, and in other cases, you need a stand-alone tool.

  • Chai

Chai is the most popular assertion library for browser and Node.js software testing. Chai integrates with any JavaScript testing framework (Mocha, Jasmine, Jest, etc.) and supports the behavior-driven development (BDD) in software testing.

Other options: AssertJ, Unexpected.

API/web services testing

The dedicated tools help check directly how the requests to an application’s business logic or external web services are processed and addressed. This allows for checking integrations and an application’s functionality 'fast and early in development.

  • SoapUI / SoapUI Pro

SoapUI is the world’s most popular test automation tool for API/web service testing. It supports HTTP, SOAP and RESTful web services. SoapUi is a simple and user-friendly tool that helps with web services performance and functional testing. It supports service mocking and complex additional configurations; Groove and JavaScript test scripting; data driven testing (DDT), HTTP recording and test reporting.

  • Postman

Postman is a popular API testing tool that supports running scripts from the command line. It has advanced features, such as API data visualization, API mocking, built-in support of variables, API monitoring, and convenient workspaces to share and organize work between team members or multiple teams.

  • REST Assured

REST Assured is an API to simplify REST services testing in Java. REST Assured is much appreciated for its flexibility and easy maintainability.

Also: JMeter, Fiddler.

Unit testing (mostly handled by developers)

Tools for this testing type ensure low-level code correctness and test a single unit of code.

  • JUnit 5

JUnit is a leader in unit testing for the Java programming language. JUnit belongs to the family of xUnit frameworks, the testing model of which is on the way to becoming a standard framework for any language (PHPUnit, CUnit, NUnit, CPPUnit, PyUnit, etc.). JUnit is supported by all major IDEs and build systems, such as Ant, Maven and Gradle.

  • TestNG

TestNG is a member of the xUnit family for Java inspired by JUnit, but it offers a more powerful functionality. Among the tool’s gains are more advanced and easier-to-use annotations and support of parallel testing.

  • Jasmine

Jasmine is a behavior-driven development framework for testing JavaScript code.

  • Mocha

Mocha is another popular test automation tool for JavaScript (especially Node.js and Angular.js). Mocha doesn’t have an in-built assertion library so it’s usually chosen by teams that want to use some specific assertion library (like Chai).

Other options: MSUnit, NUnit.

Mobile testing

Mobile testing tools help test native and hybrid mobile apps since not all web UI testing tools support testing of applications designed and developed for mobile devices.

  • Appium

Appium is a widely popular open-source and cross-platform tool that works for both Android and iOS platforms. Appium allows running automated tests on both physical devices, emulators and simulators. Based on Selenium WebDriver, it supports any programming language. The specific feature of Appium is that it allows invoking another application from the application under test, such as a camera app, for example.

  • Calabash

Calabash is a mobile test automation tool that allows testing Android and iOS native apps and hybrid applications. Calabash has an in-built function for taking screenshots in a determined instant.

  • Espresso

Espresso is an open-source testing tool by Google created to test user interfaces of native Android apps. Espresso tests both real devices and emulators. The main advantage of Espresso is faster test runs than with other mobile test automation tools and improved test coverage (up to 99% of bugs can be revealed).

Running tests in the cloud

Tools for running tests in the cloud help conduct testing for several browser/OS/device combinations without additional costs and efforts for the large test lab setup and support and for testing in parallel (especially important for massive regression testing).

  • Sauce Labs

The Sauce Labs platform provides a ready infrastructure to run over 700+ browser and operating system configurations, including those for mobile and tablet devices (simulated browsers and mobile devices, emulators and real mobile devices). In addition, the platform has a screen recorder, which captures and stores the emulated actions in the image and video formats, and in-built test analytics.

  • BrowserStack

BrowserStack is a cloud-based test automation platform that offers a large pool of browsers, OSs, and devices. It can also generate screenshots and videos of emulated actions. BrowserStack is easy to configure and use, and rather cost-effective. However, it does not allow re-using code written for Selenium in Appium-based testing.

Other options: Perfecto, LambdaTest.


Reporting tools help reduce the defect life cycle, simplify defect investigation and track down failures faster, as well as allow for the involvement of all testing stakeholders.

  • Allure

It is a popular lightweight multi-language (Java, Python, JavaScript, Ruby, Groovy, PHP, .NET, and Scala) reporting tool granting rich visual content. Allure offers a detailed representation of what has been tested and where defects are placed. Allure reports can be enhanced with text, image and video info. In addition, Allure graphs and charts with test execution statistics help non-testers better comprehend and estimate test results.

BDD testing

BDD testing tools help use the natural language to describe the behavior of the features under test.

  • Cucumber

Cucumber is a mainstream BDD tool with both open-source and commercial vesrsions.. Initially, it was designed in Ruby, but today it supports a variety of languages, including Java and JavaScript. Cucumber reads text specifications in Gherkin and maps them to Ruby code to verify those specifications.

  • SpecFlow

Basically, SpecFlow is a Cucumber for .NET. SpecFlow is an open-source tool that reads text specifications in Gherkin and maps them to C# code to verify those specifications.

Other options: Cucumber-JVM, JBehave, JGiven.

Test runners

You may use a test automation framework without in-built test runners or employ a third-party automated test runner to leverage capabilities that are more advanced.

  • Karma

Karma is a popular JavaScript test runner that plugs into many testing libraries and frameworks (Jasmine, Mocha, etc.). Karma runs tests inside real web browsers (Google Chrome, Firefox, Opera, and so on) and has in-built reporting. Karma automatically re-runs tests if needed, which means you can have the tool running unattended. You can also test against several browsers in parallel. Karma is not limited to the web front end and can be used for testing the Node.js back end as well.

  • Ava

Ava is a minimalistic test runner used for Node.js projects. Ava’s advanced capabilities include parallel test runs through separate processes, ‘fail fast’, storing snapshots (supports Jest snapshots), skipping tests and showing test coverage reports.

Other options: Wallaby, InternJS.

Codeless scripting

Codeless scripting tools capture the way a tester interacts with software and replay it on demand.

  • mabl

mabl is a paid ML-driven cloud-based tool for automated testing. It tests web apps, APIs, email and PDFs. mabl goes with test self-healing – tests adapt to UI changes automatically. The tool supports scheduled test runs and offers comprehensive test results reporting with screenshots and detailed diagnostic information. mabl tests can be created only in Chrome. However, the created tests can be re-used across other browsers (Firefox, Safari, Internet Explorer).

  • Testim.io

Testim is a commercial AI-driven record-and-replay tool platform. Testim supports dynamic locators and can run tests both on-premises and in the cloud, but it offers only high-level reporting.

Test management

Test management tools help plan and structure the testing process and its phases, coordinate manual and automated software testing efforts, store information on testing activities and progress and report the state of quality assurance.

  • Zephyr

Zephyr is the most popular test management tool natively embedded in Jira, which means you can have test issues created, tracked and reported just like other Jira tasks. Zephyr provides both forward and backward traceability reports, allows for linking requirements and test cases, can run a group of tests for a particular project version (to test a cycle/sprint deliverables), offers execution reports and provides a test board with multiple individual configurable quality metrics. However, Zephyr does not have a feature to generate test suite/requirement-based reports.

  • PractiTest

PractiTest is a cloud-based tool for end-to-end test management. PractiTest is easy to use due to intuitive GUI and hierarchical filters to organize information. It is packed with features, such as an ability to report issues directly from emails, external dashboards and embedding graphs support, and session-based test management. PractiTest integrates with Jira, Bugzilla, Mantis; Jenkins, Slack, Zapier and more.

Other options: TestRail.

Test data generators

These tools help quickly get realistic test data like names, phone numbers, IPs, emails, addresses, filenames, commerce, company names, finance, images, and more.

  • Mockaroo

Mockaroo is an online service for automated data generation. Mockaroo can provide test data in CSV, JSON and SQL formats. It generates up to 1,000 rows of data of various types in the free edition and up to 10 million rows in the paid version.

  • Faker.js

Faker.js is a JavaScript library that generates fake data in Node.js and browser. Faker.js provides a command-line interface (CLI) to generate the data.

CI/CD tools

By aligning the development and testing environments, these tools help regularly run tests after every change in software (either every time changes are submitted or at a scheduled time, say, during night builds) and automatically prepare the code release.

  • Jenkins

Jenkins is the leading open-source CI server written in Java, which supports both on-demand and scheduled tests. Jenkins is better suited for enterprise-scale projects, as it offers the needed flexibility. At the same time, it requires time to set up and configure, and the dedicated staff to run, support and customize the environment.

  • Travis CI

Travis CI is easy to set up thanks to pre-installed services and easy to maintain thanks to clear and detailed documentation. Travis CI comes with cloud-based hosting that allows testing against various environments, various machines and OSs. Travis CI supports cluster and parallel testing. The tool is free for open-source projects only.

Other options: Bamboo, CircleCI, Bitrise CI (mobile).
