Jest vs Mocha

Testing-tool requirements, dependency surface, supported engine declarations, and exact-release advisories.

How to use this comparison

Choose according to your required APIs, runtime, integration constraints, and license terms. A smaller provider bundle or higher download count does not establish the best choice. Measurements use the same provider scenario; application imports and peer dependencies can change the outcome.
