Jest vs Zest: What are the differences?
## Introduction
The Key differences between Jest and Zest are highlighted below.
1. **Testing Framework**: Jest is primarily a testing framework for JavaScript, while Zest is an automation testing tool that provides a platform for web application testing across different browsers and operating systems.
2. **Community Support**: Jest has a larger community base, with extensive documentation, tutorials, and support available, making it easier to troubleshoot issues and find solutions compared to Zest, which has a smaller community.
3. **Functionality**: Jest is specifically designed for unit testing and includes features like mocking, assertion, and snapshot testing, while Zest is more focused on end-to-end testing and offers functionalities like test scripting, recording, and playback for web automation.
4. **Integration**: Jest seamlessly integrates with popular JavaScript frameworks like React, Angular, and Vue, providing specific functionalities tailored for these environments. In contrast, Zest is adaptable to various programming languages and technologies, making it suitable for a broader range of applications.
5. **Performance**: Jest is known for its fast and efficient test execution due to parallel testing capabilities and optimized test running, resulting in quicker feedback on code changes. On the other hand, Zest may have longer execution times for complex test scenarios involving multiple browsers and environments.
6. **Extensibility**: Jest offers a robust plugin system that allows developers to extend and customize the testing experience with additional functionalities and integrations, whereas Zest may have limited flexibility in terms of extending its core features.
In Summary, Jest and Zest differ in their focus on testing frameworks, community support, functionality, integration, performance, and extensibility.
