What is WebDriverIO?

WebDriverIO is the leading test automation framework for both web and mobile applications. It is written in JavaScript and runs on NodeJS.

WebDriverIO – is an independent framework, which means any corporate interests don’t influence which way it should be developed and where it is supposed to go. In fact, it is a unique tool in comparison to many automation tools. WebDriverIO is a definitely open-source project that evolves within open governance and is owned by a non-profit OpenJS Foundation.

A vast NodeJS community around the world helps the framework grow with new capabilities and cares about its stability. Followers communicate within Gitter Also you can ask your ques within Stack overflow. There are more than 500+ discussions there. You can see many useful links on the official Resource page in one place.

Automation testing with WebdriverIO

WebDriverIO is a flexible and powerful automation framework with good documentation, functionalities a variety of plugins and good support as we just mentioned before.

Extract from official Docs, it emphasises wdio is designed to be:

• Extendable – adding helper functions, or more complicated sets and combinations of existing commands is simple and really useful
• Compatible – testing framework coded with wdio possible runs on the WebDriver Protocol for true cross-browser testing as well as Chrome DevTools Protocol for Chromium based automation using Puppeteer.
• Feature Rich – the variety of built-in and community plugins allows QA teams to easily integrate and extend your setup to meet the requirements of Agile SDLC.

Thus, WebDriverIO is perfect choice to automate E2E tests for modern JavaScript web applications. As it is built in NodeJS, testers and developers can automate their test scripts using JavaScript, as well as with TypeScript (it is up to you). And at the same time, they can do it in a fast and reliable way. The tests performed on WebDriverIO are simple and concise.

Especially this applies to web applications designed:

• Modern frontend frameworks – such as React, Vue, Angular, Svelte etc.
• Hybrid mobile applications – empowered by iOS and Android applications using Appium, for instance, the Ionic JS framework or native mobile applications running in an emulator/simulator or on a real device.
• Native desktop applications – designed with Electron.js for Windows and macOS.
• Unit or component testing of web components in the browser.

WebDriverIO is appropriate for both Behavior Driven Development (BDD) and Test Driven Development (TDD) which one more time makes opt for it for automation testers.

To start with WebDriverIO, you need just 2 CMD commands

Look at the code extract and check out by yourself how you can initialize WDIO testing project and run your first wdio auto test really per a few clicks:

npm init wdio . //initialize WebDriverIO 
npm init wdio ./path/to/new/project /* create a project with the basic structure
in a designated folder */
yarn create wdio ./path/to/new/project //create a project with yarn packages
npx wdio run ./wdio.conf.js // run tests

Amazing! Great implementation of the idea by wdio development team, isn’t it?

The first command downloads the WebdriverIO CLI tool that wizard you to configure your test suite by prompting a set of questions that guides you through the setup. You can pass a –yes parameter to pick a default set up which will use Mocha with Chrome using the Page Object pattern. CLI also provides information on all available third-party framework adaptations, reporters, diverse services, etc.

And the second command runs your tests, by default it is the first login test. More detail with adding parameters running test scripts in Docs

Why do many QA teams choose WebDriverIO?

Eventually, in one voice, QA engineers note advantages, and we made an attemptе to categorize them. Keep these in mind when looking for a solution for your testing framework.

Benefits of test automation with WebdriverIO:

• Parallel test execution and cross-browser test automation. WebdriverIO is based on Web Standards, is supported by all browser vendors and guarantees a true cross-browser testing experience with all major browsers Chrome, Firefox, Edge, Internet Explorer, and Safari.
• Supports integrations to Chrome DevTools and Google Lighthouse, which are widely used developer tools.
• Diverse selectors and auto-waiting mechanism are able to cover common user interactions.
• Convenient test runner comes with a CLI play great utility tandem thanks to their configuration potency. This contributes to extendability due to the possibility of adding helper functions, building more complex combinations of available commands and even the ability to create your custom commands.
• Integration with commonly used Cloud and CI/CD tools. Can be used locally, as well as in the cloud, through services like Sauce Labs, Lambdatest or BrowserStack.
• Carries multiple reporters like Junit, Allure, Spec, HTML, Video, JSON and custom reporting to your convenience.

Sync WebdriverIO tests with manual testing

Since WebdriverIO is a loved tool by many test engineers, the testomat.io team didn’t want to be left out and implemented integration with it as a part of the Test automation Integrations group.

Seamless WebdriverIO integration helps many Agile teams bring their automation test management to the next level. Makes testing and debugging of the testing framework scripted with WebdriverIO a lot more efficient for our customers. Automation QA engineers are able to easily import their tests into the test management system and make them visible to the whole team.

Finally, they can collaborate with non-tech teammates in one space before they difficulty achieved a common understanding.

Let us show you how everything works

Getting started WebdriverIO from example

Our team prepared a bunch of Demo projects for success starting with the testomat.io TCMS. Besides WebdriverIO following through the link, you can find Cypress, Playwright, Cucumber, Jest, CodeceptJS and other examples of testing frameworks. Download the needed project there and try how it works by yourself.

These are the steps you need to follow to run the example in testomat.io test management:

Before exploring how to run WebdriverIO tests with test management, first of all, the prerequisites mentioned below have to be met.

Prerequisites for WebdriverIO testing framework

Check the NodeJS version, enter the following commands:

$ node -v

Install NodeJS or update the NodeJS, by entering the following command in project directory:

npm install --save-dev

If everything goes without errors, let’s head Step by Step!

#1 Create a new test project

Start by Sign Up or Sign In to the TMS, and then create your test project by honouring the system tips. We begin by writing the project name and choosing a classical type of project, as in the picture below. You may configure your WebDriverIO test project using different settings according to your testing frameworks, such as Chai or Mocha, JavaScript language or TypeScript, classical project or BDD. You will bump all these options as we go along.

After you create your project, get into it. Select Import Automated tests on the dropdown menu in the top right corner. Thanks to the Advanced Importer you can import your automated tests to the test management system with a few clicks and make them visible there for the whole team.

Configure import according to your testing project. For instance, we chose a project using WebDriverIO with Mocha and JavaScript option.

#2 Generate API key and import autotests

Our TCMS is a wise tool. TCMS recognizes your laptop OS and generates a command with API key according to it. You should copy this command and execute it on CMD. This one uploads your WebdriverIO tests from source code to test management.

Look at the console, how the importer analyzes code accurately and displays the number of founded tests in the test framework. If you enter your project, you will see these tests. You can view their structure by expanding the tree. You may enter your suites and check test cases inside.

Now you can synchronize your manual tests alongside automated tests scripted with WebdriverIO in one place and get aggregated test result reports and analytics. Even the number of tests increases significantly – custom labels and tags help organize them conveniently. Sort, Change order, Filter and Search test cases quickly in scale.

Please note: with each new import, the intelligent importer will analyze test cases present in it or not. If there are no new test cases in the test management system yet, you will add new ones. These tests will be marked as out of sync by TCMS. Vice versa, if they are not in code, they will be marked as detached test cases. You might check them and delete unnecessary tests.

#3 How do I create a report in Wdio?

Track test results to test management with our advanced reporter. Test management testomat.io reporter connects with WebdriverIO an open-source test automation tool. Copy and paste this command into CMD to install reporter:

npm i --save-dev @testomatio/reporter

#4 Configure .conf file:

We suggest adding our reporter (test management plugin) along with existing reporters in wdio.conf.js. For this purpose copy configuration suggested by TMS to the project which can find out in the DEMO project as well.

const Testomat.io = require('@testomatio/reporter/lib/adapter/webdriver');

reporters: [
[Testomat.io, {
apiKey: process.env.TESTOMATIO
}]
],

#5 Execute WebdriverIO scripts

You are ready now to run your WebdriverIO tests with test management. Execute WebdriverIO scripts and receive results synced in test management.

Run the following command from your project folder:

TESTOMATIO=<API key> npx start-test-run -c 'npx wdio'

Once the tests have finished running, the CLI will generate a report link. Test results will appear through the console on the test management dashboard. Share this test result link with stakeholders by email or messengers. Choose whom available detailed report. The type of public report does not contain security-sensitive info.

We have performed tests oft, and each of these runs saves some historical data.

We can analyze the results of running tests using advanced analytics. The following testing metrics are available on the Project Analytics dashboard and Global Analytics dashboard. Our team are currently working on expanding with new widgets.

A key characteristic of the CI/CD pipeline is the use of automation to ensure code quality. Rich reporting and real-time monitoring are essential to understand and quickly address any problems, especially matters to CI/CD pipeline. Collection and gathered statistics and metrics are necessary. Pipeline successes and failures, as well as how long each test ran can be measured by key indicators and stored in Runs history over time.

Analytics shows the history of your test runs and failures, flaky tests, slowest tests, never run tests as well as test automation coverage of your test scope.

Statistics are gathered by collecting all available test run results for the project and tags which are marked test cases. Analytics data is available on a paid subscription. You are able to filter and sort your test cases from a low to high rate or by tags.

In detail, we describe each step precisely and in order in official Documentation as well. Check it for more options.

Running WebdriverIO test on CI\CD

QAs can run their tests in the cloud and on CI\CD besides on a local machine. CI\CD test execution carries out testing delivery much faster.

Moreover, if you set up a CI\CD integration connection, you can run your tests immediately from the test management system, and non-technical specialists directly from Jira.

So, our test management solution support running wdio tests on CircleCI, AzureDevOps, Jenkins, GitHub, Gitlab, Bamboo etc.

• Running WebdriverIO test on GitHub Actions CI
• End-to-end testing with GitLab CI\CD and WebdriverIO
• WebDriverIO Integration With Cucumber
• Test Automation with CircleCI & Reporting
• Automating Tests in Azure Pipelines

Comparison table: WebdriverIO VS Cypress VS Selenium

Most of today’s software development job openings request JavaScript knowledge to be used for test automation, given the many advantages of JavaScript automation tools like WebdriverIO, Cypress, TestCafe, Nightmare, CodeceptJS, Playwright and BDD Cucumber.

As you can see by yourself, our testing tool offers a great alternative to test reporting for all these test frameworks, and much more it helps you keep your tests in a clear organizational structure.

The test case management tool testomat.io has a free subscription forever, so you should not worry you lost your tests. They will be stored securely.

Let me know what you think about this setup, and/or if you have any questions, please do not hesitate to post them below. Thank you for taking the time to read my article.

The content is available also in video format if you convenient reproduce the steps to visualize your tests and get an informative report by watching.

Which automation testing tool is in demand?

When it comes to automation testing tools, there is no one-size-fits-all solution. There are multiple criteria to consider, including usability, key features, setup and integrations, customization, cost, etc. Since there are so many available automated QA tools on the market, we’ve presented above the ones we think are best for various testing needs.

Bottom line: Are you over the first hurdle?

Opting for automating testing is a huge step for any organization. When evaluating and comparing automation testing tools, it’s essential to take time. Looking for the right test automation tool can be a long process, but putting the research in now and properly outlining your goals and expectations is a must to meet with success and drive a great ROI.

The post Best test automation tools 2025<br>comprehensive list appeared first on testomat.io.

Did you know that JavaScript has been named the most commonly used programming language for 8 years in a row? 67.7% of the developers use JavaScript

Discover Open Base link, there placed 201 best JavaScript testing frameworks and libraries for debugging. All these libraries and frameworks offer pre-written code and extra features.

Why do QA Automation Engineers tend to use ready code?

JavaScript libraries contain various code, functions, methods, objects to perform practical tasks, that QA Automation Engineers can reuse and re-purpose, instead of writing code from zero.

Contain wide-ranging out-the-box functionalities for launching the test environment. Let’s say CI/CD. If it is UI testing some frameworks establish a connection with the browser, for instance, the well-known Selenium Webdriver. Provide integration with other third party tools.  Give fake data, mocking support and many more…

Thus, JavaScript testing frameworks, bring simplicity to the entire testing process. Every JavaScript testing framework makes automation testing easier and speeds up the testing process. It saves a lot of time, effort and money for stakeholders. Moreover, these are the motive behind creating JavaScript testing frameworks and libraries, which is why you can find dozens of them for various use cases. Of course, even the best JavaScript testing framework has its own set of pros and cons.

The choice of a particular tool depends on the unique requirements of the project. Determines by the tech stack. Project progress in test automation, percentage of Automation Test Coverage has to be achieved by automated testing in comparison to manual testing. What problems might it solve? QA team testing experience. Dev skills and their previous experience.

To use a particular JavaScript framework, should read the JS framework’s documentation you intend to use and follow the steps from testing framework Docs. Rest assured that in Docs, you will find many good ready-to-use examples of tests to deal with daily routines.

Also, we would like to pay your attention to Chai. Make sure, you will apply it too. Chai is the assertion library and is used together with almost all javascript testing frameworks, which are noted below. As we know assertions are the base component of test cases. Chai provides functions and methods that ensure compare the output of a certain test with its expected value.

Chai is popular JavaScript testing library due to its simple BDD syntax. Its syntax is very similar to human language like English and makes tests more understandable for all participants of the testing process.

A list of JavaScript testing frameworks you should know by default

Mocha

MochaJS is certainly the most used JavaScript testing framework. Provides both frontend and backend testing.

Main advantages:

• Incredible expandability of Mocha. Mocha is powered by a lot of plugins for every taste, including real time reporting, screenshots and video capturing test results.
• Integrated with other JS testing frameworks, for example Webdriver.io, CodeceptJS.
• The best for starting, thank to there are many code documents, articles video tutorials on the internet.
• Sequential execution of test cases with flexible reporting.
• Mocha helps you to easily map exceptions with the relevant test cases
• Mocha support all browsers.
• It can easily support generators.

If you are looking for a very flexible and extensible testing tool, MochaJS will be an excellent choice!

CodeceptJS

What is CodeceptJS? CodeceptJS itself is not so much a testing tool rather than it is a wrap-around multiple testing tool able to test any web application. This means that with CodeceptJS you can pick between frameworks like WebDriverIO, Protactor, Nightmare, Appium Selenium, Appium, Playwright, Puppeteer and use the same script to test on all of those. You can even test your API with and integrate this with your end to end tests.

Main advantages:

• Multiple testing tools in one.
• CodeceptJS offers scenario-driven tests. These test scenarios are linear as the user’s behavior and his actions on a site.
• Special BDD-style syntax makes test code concise and readable.
• Expandable you can run tests without substantial changes in any of the popular test runners.
• Codecept testing environment is easy to set up and maintain.

Pretty good choice for small and middle projects

Cucumber

It is a cross-platform Behavior Driven Development (BDD) tool. Remember, Cucumber is not a testing tool as well as CodeceptJS. It is just a tool for describing users’ behavior, tending to how an app should work. It explains through Steps written in Gherkin syntax. It doesn’t require you, to automate user behavior verification of your system if you find it useful.

Main advantages:

• Cucumber tests are completely understandable for the business stakeholders, who are not familiar with testing at all, as they can easily read the code. Test reports are written in business readable English as well.
• Cucumber is quick and easy to set up execution and allows reusing code in the tests.
• One good feature is that both specification and test documentation are uploaded in a single up-to-date document.
• The code can be used together with other testing frameworks written not only on JavaScript but also on Java, Python and others.

Selenium WebDriver

Selenium Web Driver includes a JavaScript testing framework and is accepted for performing automated cross-browser testing web applications. Also, Selenium Web Driver is used for other programming languages. Support coding in Java, Python, PHP, etc.

Main advantages:

• Simple syntax thus can be easily learned by testers who want to get introduced to automated web testing quickly.
• Flexibility and extensibility.
• Scalability, performing parallel testing.
• A large community are always there to resolve your problem. Because Selenium Web Driver is the oldest automation testing tool.

TestCafe

TestCafe is a great alternative to Selenium-based tools. The library uses its own test structure and another way to implement control over the browser – the implementation of JavaScript scripts. You gain complete control over the JavaScript execution cycle. UI tests usually are run separately from others.

Main advantages:

• Easy to start testing.
• Clear and more readable syntax in comparison with Selenium Web Driver.
• Works in any browser and on any device.
• Parallel testing in several browsers at once.
• Convenient error reports.

Main advantages:

• WebdriverIO gives you a full-fledged framework out of the box. It doesn’t require you to implement anything from scratch, as you would with straight Selenium.
• It comes with everything you need to build scalable and sustainable test suites and contains extra features not found in the straight Selenium version.
• Out-of-the-box integrated with other JS testing frameworks, as for example Mocha, Chai, CI\CD tools, Reporters.

Cypress

Cypress is a JavaScript end-to-end testing framework that runs in the browser. Cypress definitely belongs to the top javascript testing frameworks thanks to their huge popularity.

Due to architectural design differences from other test frameworks, it provides customers with faster and more accurate test execution. It includes Test Runner and logs for interactive test execution, making it easy to debug test execution.

In addition, Cypress is intelligent enough to recognize that after saving a test file, the tester will rerun it. As a result, there is no need to define implicit and explicit waits.

Main advantages:

• Complete and clear documentation.
• Parallel and cross-browser testing.
• Convenient startup and debugging tools.
• Faster and more accurate running tests.

Jest

Jest is a great JS testing framework from Facebook. Jest is a framework for Unit Testing, a way for you to test the individual functions and components of your application, that future commits don’t break it unexpected.

Main advantages:

• Fast and highly productive. So, it is perfect for React-based applications, especially for large projects.
• Jest compatible with Babel-based projects, TypeScript, Angular, VueJS and other frontend frameworks, also many NodeJS test libraries.
• Everything you need for unit testing comes out of the box.
• Jest has excellent documentation, active worldwide community and support for all modern IDEs.
• An intelligent parallel testing mechanism.
• Working in monitoring mode, jest updates only those tests that could change. That makes Jest a popular JavaScript automation testing framework for unit tests.

Puppeteer

Puppeteer automates Chrome and Firefox. Mostly Puppeteer is an automation tool and not a testing framework. This means it is incredibly popular for use cases such as scraping, generating PDFs, etc. Puppeteer is a test automation tool maintained by Google. It uses the same debugger protocol Selenium (well, ChromeDriver) uses to perform clicks.

Main advantages:

• Puppeteer is generally easier to set up than Selenium for the development flow.
• Easy to set up and maintain
• Exellent documentation

Playwright

Playwright is a Node.js library that allows the QA Automation Engineers to control browsers through its high-level API. Playwright utilizes the same architecture as Puppeteer and is a thin WebSocket client. It uses a very similar syntax.

When the tester runs a Playwright test script, the UI is readied at the backend before the test interacts with web elements. While for other frameworks, testers have to write code for the wait explicitly.

Playwright ensures auto wait, making it easier to write concise test scripts. It also provides flexible testing through its capabilities, which covers a wide range of complex scenarios for comprehensive testing.

Playwright is a test automation tool maintained by Microsoft.

Main advantages:

• The Playwright is highly fast and stable and ensures optimal usage of resources
