No. While many frontend testing tools are popular in JavaScript ecosystems, the broader category is useful for teams working across web interfaces, component libraries, browser workflows, and UI automation.
Component testing focuses on validating individual UI units in relative isolation, while end-to-end testing validates complete user journeys across the application in a more realistic browser or runtime environment.
Start with your UI architecture and testing needs. Consider speed, browser support, maintainability, developer experience, CI integration, framework compatibility, and how well the tool fits your frontend workflow.
