Why do QA Automation Engineers tend to use ready code?
Contain wide-ranging out-the-box functionalities. Launching the test environment. If UI testing some frameworks establish a connection with the browser. Provide integration with other tools. Let’s say CI/CD. Give fake data, mocking support and many more…
The choice of a particular tool depends on the unique requirements of the project. Determines by the tech stack. Project progress. What problems it will solve. Dev skills and their previous experience.
you should know by default
- Incredible expandability. A lot of plugins for every taste, including reporting, screenshots, video capture test results.
- Integrated with other JS testing frameworks, as example Webdriver.io, CodeceptJS.
- The best for start, because there are many documents tutorial videos 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!
What is CodeceptJS? CodeceptJS itself is not so much a testing tool rather than a wrap-around multiple testing tool. This means that with CodeceptJS you can pick between 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.
- Multiple testing tools in one
- CodeceptJS offers scenario-driven testing.
- Special BDD-style syntax makes test code concise and readable.
- Expandable you can run your test without substantial changes in any of the popular test runners.
- Easy to set up and maintain
Pretty good choice for small and middle projects 👍
It is a cross-platform behavior-driven development (BDD) tool that is used to write acceptance tests for web applications.
- 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.
- Simple syntax thus can be easily learned by testers who want to get introduced to the automated web testing
- Flexibility and extensibility.
- Scalability, performing parallel testing.
- A large community are always there to resolve your problem. Because Selenium Web Driver is the oldest testing tool.
- 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.
WebdriverIO is a browser and mobile automation test framework based on Node.js and leverages Selenium.
WebdriverIO allows you to automate any application written with modern web frameworks such as React, Angular, Vue.js as well as native mobile applications for Android and iOS according to documentation.
- 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.
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.
- Complete and clear documentation.
- Parallel and cross-browser testing.
- Convenient startup and debugging tools.
- Faster and more accurate test execution.
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.
- It is perfect for React-based applications, especially for large projects.
- Compatible with Babel-based projects, NodeJS, TypeScript, Angular, VueJS, and others.
- Everything you need for testing comes out of the box.
- Excellent documentation and support for all modern IDEs.
- An intelligent parallel testing mechanism.
- Fast and highly productive.
Puppeteer automates Chrome and Firefox. Mostly Puppeteer is an automation tool and not a test tool. 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.
- Puppeteer is generally easier to set up than Selenium for the development flow.
- Easy to set up and maintain
- Exellent documentation
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.
- The Playwright is highly fast and stable and ensures optimal usage of resources
- Parallel testing launches through Browser Context
- Playwright supports Safari.
- It works on isolated sessions in browsers for grids.
- Test creation speed is high as well.
- Like Cucumber supports multiple programming languages such as Python, Java, and .NET C#
- Simple to install and set up
- Also, available community support, great documentation, detailed instructions, good example projects.
