Selene

Selene's API uses modules like `be` and `have` to write tests that read like natural language, reducing boilerplate and improving team collaboration, as shown in the quick start example with commands like `.should(have.text('Selenium'))`.

Built-in implicit waiting and retry mechanisms handle Ajax-like dynamic content automatically, minimizing flaky tests without manual sleep commands, which is a core feature highlighted in the README.

Provides comprehensive error reports for actions and assertions, making debugging easier by pinpointing failures in decomposed selectors, as emphasized in the 'Flexible filtering of collections' section.

Options like timeouts and selectors can be customized globally, per browser, per element, or per action, offering fine-grained control, as detailed in the 'Highly customizable' feature description.
