Nightwatch is more popular and widely used compared to CasperJS. Nightwatch has a larger community and more active development.
Ease of Use
Nightwatch has a simpler and more intuitive API, making it easier for developers to write and maintain tests. CasperJS, while powerful, has a steeper learning curve and requires more configuration and setup.
CasperJS provides more flexibility and control over the testing process. It allows you to interact with the DOM and perform more complex actions. Nightwatch, on the other hand, follows a more opinionated approach and provides a higher-level API for easier test creation.
Nightwatch has better documentation with comprehensive guides and examples, making it easier for developers to get started and find answers to their questions. CasperJS documentation, while available, may not be as extensive or up-to-date.
Nightwatch is actively maintained and regularly updated with new features and bug fixes. CasperJS, on the other hand, has seen a decline in maintenance and updates in recent years, which may indicate a less active community and potential compatibility issues with newer versions of browsers and dependencies.
