Jest has revolutionized test automation for JavaScript projects. Developed by Facebook, this powerful and intuitive test framework enables teams to ensure the reliability, efficiency, and quality of their software products. With its robust features, seamless integration capabilities, and ease of use, Jest helps accelerate the development process, minimize risks, and deliver flawless software products with confidence.

When Do You Need Jest Test Automation Services?

Rapid Development Cycles

If your team practices agile principles with frequent releases, Jest-based test automation can streamline your QA process. Its fast setup and execution allow for quick feedback loops, enabling developers to iterate rapidly without sacrificing quality.

Complex Application Logic

When it comes to applications with intricate business logic or intricate workflows, manual testing can be time-consuming and error-prone. Jest, as a robust testing framework, allows for thorough testing of complex scenarios, ensuring that every feature of your application functions as intended.

Cross-Platform Compatibility

With applications being accessed across various devices and browsers, ensuring cross-platform compatibility is crucial. Jest provides excellent support for testing across different environments, allowing you to catch compatibility issues early in the development cycle.

Large Codebases

Managing testing in large codebases can be daunting without proper automation. Jest comes with great scalability, providing efficient test management and execution even in complex codebases, which makes it ideal for projects of any size.

Continuous Integration and Deployment (CI/CD)

Integration of Jest into your CI/CD pipeline enables automated testing with every code change. This ensures that new features and fixes are thoroughly tested before deployment, reducing the risk of introducing regressions into your production environment.

Lack of time

If every minute counts, Jest is the best tool to use for test automation. First of all, it does not require configurations on the majority of JavaScript projects. Secondly, Jest can run tests in parallel. Moreover, to fast-track the testing process, it runs previously failed tests in the first turn and adjusts runs based on the time that test files take.

Maintainability and Refactoring

As your application evolves, code maintenance and refactoring become inevitable. The comprehensive test suites of Jest serve as a safety net, allowing you to refactor with confidence and detect any unintended side effects.

Collaborative Development

Jest test automation promotes collaboration by providing a standardized testing framework. Developers can easily understand and contribute to existing test suites, fostering a culture of shared responsibility for code quality.

Dev capacity:



Didn’t have a formal QA process

Built smooth and well-working processes

Didn’t make automated testing

Test automation : smoke, API, UI on all supported browsers

Testing was carried out by the devs

Full coverage of the application by test cases

Test coverage :



Existing workflow in Jira didn’t allow to understand how many bugs were left unfixed before the release and their priorities

Adjusted the Jira workflow, integrated TestRail with Jira to be able to see statisticls of the issues per release

The lack of test documentation

Developed necessary test artifacts that adhere to industry standards and are easily maintainable

No Automation test coverage

Added multithreading to run tests in parallel on 10 different threads, which reduced the time of the test run in 7 times
